WHAT ARE AIR CONDITIONING SYSTEMS?
Air conditioning systems are advanced mechanical climate control systems used to control indoor temperature (dry-bulb temperature), relative humidity, air quality (IAQ - Indoor Air Quality), and air circulation. In modern HVAC (Heating, Ventilation and Air Conditioning) applications, these systems perform not only cooling, but also multi-parameter environmental control functions such as heating, ventilation, filtration, humidification, and dehumidification. In this respect, air conditioning systems are critical engineering solutions not only for achieving comfort conditions, but also for human health, process safety, and energy management.
Today, air conditioning systems are designed with different capacities, control algorithms, and system architectures for a wide range of applications such as residential buildings, commercial facilities, hospitals, cleanrooms, data centers, and industrial plants. Engineering parameters such as heat gain, cooling load, intended use of the space, and air change requirements are taken into account during system selection. These calculations are generally performed in accordance with the ASHRAE Handbook and the relevant European standards.
Energy efficiency is one of the most important design criteria of today's air conditioning systems. In this context, performance parameters such as COP (Coefficient of Performance), EER (Energy Efficiency Ratio), and SEER (Seasonal Energy Efficiency Ratio) play a decisive role in system selection. In addition, Eurovent certification is accepted as an important reference for verifying equipment performance. In line with current environmental policies, the use of new-generation refrigerants with low GWP (Global Warming Potential), such as R32 and R1234yf, is becoming increasingly widespread.
As a result, air conditioning systems are not merely comfort equipment; they are complex systems based on engineering calculations and are critically important in terms of energy efficiency, sustainability, and indoor air quality. Correct project design and appropriate system selection both minimize operating costs and provide maximum user comfort.
SPLIT AIR CONDITIONING SYSTEMS
Split air conditioning systems are space-based climate control solutions operating on the direct expansion (DX - Direct Expansion) cycle principle and consisting of an indoor unit (evaporator) and an outdoor unit (condenser + compressor). In these systems, the refrigerant circulates within a closed thermodynamic cycle and transfers heat through evaporation and condensation processes. Indoor air passing over the evaporator coil in the indoor unit is cooled and dehumidified by transferring its sensible and latent heat to the refrigerant. The fluid, whose pressure and temperature are then increased by the compressor, condenses in the condenser located in the outdoor unit and releases heat to the outdoor environment. High-efficiency refrigerants with relatively low environmental impact, such as R32 and R410A, are commonly used.
The inverter compressor technology used in split air conditioning systems provides high energy efficiency under partial load conditions by adjusting the compressor speed through frequency control. In this way, the system's COP (Coefficient of Performance), EER, and SEER values are optimized, while inrush currents and mechanical wear are minimized. In addition, precise refrigerant control is provided by an electronic expansion valve (EEV), thereby improving system stability.
These systems offer advantages such as low noise level (dB), compact structure, easy installation, and low initial investment cost. However, they are not preferred in large-volume or multi-zone projects due to limited air distribution, the absence of fresh air integration, and limited integration with central automation systems. Therefore, split air conditioning systems stand out as technically and economically optimum solutions for residences, small offices, and low-volume commercial spaces.
WALL-MOUNTED SPLIT AIR CONDITIONING SYSTEMS
Wall-mounted split air conditioning systems are among the most commonly used air conditioning systems and are an ideal climate control solution especially for residences, small offices, and individual use areas. In these systems, the indoor unit is generally mounted on the upper part of the wall in order to provide homogeneous air distribution within the space. Wall-mounted split air conditioners are equipped with inverter technology that provides energy savings by offering high efficiency in low-capacity ranges. In this way, both low energy consumption and optimum indoor comfort are achieved.
Wall-mounted split air conditioning systems stand out with their compact design, easy installation, and low initial investment cost. In addition, their filtration systems help improve indoor air quality (IAQ) by removing dust, pollen, and particles from the environment. However, air distribution may remain limited in large-volume spaces. For this reason, wall-mounted split air conditioning systems are among the most preferred air conditioning solutions in small and medium-sized spaces.
FLOOR-STANDING SPLIT AIR CONDITIONING SYSTEMS
Floor-standing split air conditioning systems are vertical air conditioning systems placed on the floor and developed for large-volume areas requiring high-capacity climate control. These systems are generally preferred in restaurants, shops, showrooms, and large office areas. Thanks to their high airflow rate, floor-standing split air conditioning systems provide more effective air circulation in large areas and offer rapid cooling/heating performance.
In these systems, air distribution is made more homogeneous thanks to the powerful fan structure and wide air discharge angle. In addition, floor-standing split air conditioners equipped with inverter technology are optimized in terms of energy efficiency. However, these systems are less preferred in residences due to the disadvantage of occupying floor space and their limited use in terms of aesthetics. Floor-standing split air conditioning systems stand out as a powerful and effective air conditioning solution in large-volume commercial areas.
CASSETTE TYPE SPLIT AIR CONDITIONING SYSTEMS
Cassette type split air conditioning systems are advanced air conditioning systems installed inside suspended ceilings and providing homogeneous air distribution through their four-way airflow feature. These systems are among the ideal solutions that combine aesthetics and performance, especially in offices, shopping malls, hotels, and commercial areas. Cassette type split air conditioning systems provide a significant advantage in terms of spatial aesthetics due to their structure that can be concealed within the ceiling.
In these systems, air is distributed evenly in four different directions, minimizing temperature differences within the space. In addition, effective climate control is provided even in large-volume areas thanks to the high-airflow fan structure and wide discharge area. Cassette type split air conditioning systems can be integrated with central control systems and increase the level of comfort. Thanks to these features, cassette type split air conditioning systems are among the professional air conditioning solutions frequently preferred in commercial projects.
CEILING TYPE SPLIT AIR CONDITIONING SYSTEMS
Ceiling type split air conditioning systems are air conditioning systems preferred in areas without suspended ceilings and operate by being mounted on the ceiling. These systems are generally used in large-volume spaces where cassette type air conditioning cannot be applied architecturally. Ceiling type split air conditioning systems provide effective air distribution in large areas thanks to their long-distance air discharge capacity.
In these systems, air is generally blown in one direction or at a wide angle, creating air circulation throughout the entire space. Rapid cooling and heating performance is achieved thanks to the high fan capacity. In addition, energy efficiency is increased with inverter technology. Ceiling type split air conditioning systems are among the powerful air conditioning systems preferred especially in restaurants, workshops, and commercial areas.
DUCTED TYPE SPLIT AIR CONDITIONING SYSTEMS
Ducted type split air conditioning systems are advanced air conditioning systems that offer concealed installation and can distribute air to multiple spaces through air ducts. These systems are considered hybrid solutions that combine the comfort of central air conditioning with individual systems. Ducted split air conditioning systems offer significant advantages in terms of aesthetics and performance, especially in villa, office, and commercial projects.
In these systems, the indoor unit is generally concealed inside the suspended ceiling, and air is distributed to the space through grilles via the duct system. In this way, homogeneous air distribution and high comfort are achieved. In addition, the ability to integrate fresh air is one of the most important advantages of these systems. Ducted split air conditioning systems are frequently preferred in professional projects by offering low noise level, high comfort, and an aesthetic appearance.
MULTI SPLIT AIR CONDITIONING SYSTEMS
Multi split air conditioning systems are advanced air conditioning systems operating with direct expansion (DX - Direct Expansion), in which multiple indoor units can be connected to a single outdoor unit, and are optimized especially for multi-room residences and small/medium-sized commercial spaces. In these systems, climate control of multiple spaces is provided through a single outdoor unit, while each indoor unit can be controlled independently. This feature allows different temperature set values to be assigned to each space through zoning capability and significantly increases user comfort. Multi split air conditioning systems reduce external facade clutter by offering compact solutions both aesthetically and from an engineering perspective.
In multi split air conditioning systems, the capacity of the outdoor unit is calculated according to the total cooling/heating load of the connected indoor units, and the system is generally designed to operate with high efficiency under partial load conditions. Thanks to inverter compressor technology, the compressor speed is continuously modulated, thereby optimizing energy consumption. While system performance is evaluated using COP (Coefficient of Performance), EER, and SEER values, Eurovent certification is accepted as an important reference for verifying equipment performance. In addition, ERP (Energy Related Products) directives are the fundamental regulations that determine the energy classification of these systems.
However, in multi split air conditioning systems, piping distances, elevation differences, and total capacity must be designed within specific limits. Otherwise, system performance may decrease. In addition, due to the configuration connected to a single outdoor unit, a failure that may occur can affect all indoor units. Therefore, multi split air conditioning systems stand out as one of the most appropriate and balanced air conditioning solutions in villa, residence, and small office projects as an alternative to central systems.
TYPES OF INDOOR UNITS USED IN MULTIDISCIPLINARY CLINICS
Multi split air conditioning systems used in multidisciplinary clinics must meet not only temperature control requirements, but also critical parameters such as hygiene, low noise level, and controlled air distribution. Therefore, indoor unit selection must be made carefully according to the intended use of the clinical area, such as examination room, waiting area, or laboratory. The most commonly used indoor unit types in clinical projects are detailed below.
WALL-MOUNTED INDOOR UNIT (CLINICAL APPLICATIONS)
Wall-mounted indoor units are air conditioning solutions preferred in multidisciplinary clinics, especially in examination rooms, doctor rooms, and small-volume areas. These systems prioritize patient comfort thanks to their compact structure and quiet operating principle. Wall-mounted indoor units equipped with advanced filtration systems improve indoor air quality (IAQ) by filtering particles, dust, and allergens from the ambient air. These units, which can operate in integration with multi split air conditioning systems, provide individual control and allow different temperature settings in each room.
CASSETTE TYPE INDOOR UNIT (CLINICAL APPLICATIONS)
Cassette type indoor units are preferred in multidisciplinary clinics in waiting areas, polyclinic entrances, and large-volume common areas. These systems, installed inside suspended ceilings, provide homogeneous air distribution thanks to their four-way airflow feature. This increases comfort levels in clinical environments by minimizing temperature differences. In addition, their visually concealed structure preserves architectural integrity. Cassette type indoor units that operate compatibly with multi split air conditioning systems can also be integrated with central control systems.
DUCTED TYPE INDOOR UNIT (CLINICAL APPLICATIONS)
Ducted type indoor units are one of the most preferred professional air conditioning solutions in multidisciplinary clinics. These systems allow the indoor unit to be completely concealed and distribute air through grilles via the duct system. In this way, they offer a superior solution in terms of both aesthetics and hygiene. Ducted split air conditioning systems are an ideal option for improving indoor air quality in clinical environments because they are suitable for fresh air integration. In addition, they maximize patient and staff comfort thanks to their low noise level and homogeneous air distribution.
CEILING TYPE INDOOR UNIT (CLINICAL APPLICATIONS)
Ceiling type indoor units are air conditioning systems preferred in clinical areas where suspended ceiling applications are not possible. These systems provide effective air circulation in medium and large-volume areas thanks to their wide-angle air discharge capability. They can be used especially in laboratories and technical spaces in clinical environments. Ceiling type split air conditioning systems offer rapid cooling and heating performance thanks to their powerful fan structure. By operating in integration with multi split systems, they allow independent control of different areas.
FLOOR-STANDING INDOOR UNIT (CLINICAL APPLICATIONS)
Floor-standing indoor units are used in multidisciplinary clinics in large-volume areas, particularly in entrances and waiting halls with heavy human traffic. They provide rapid climate control thanks to their high airflow rate and powerful discharge capacity. These systems operate by being mounted on the floor and create effective air circulation in large areas. However, in clinical environments with high hygiene requirements, they are generally preferred as a supporting solution together with other systems.
VRF / VRV AIR CONDITIONING SYSTEMS
VRF (Variable Refrigerant Flow) or VRV (Variable Refrigerant Volume) air conditioning systems are central climate control solutions with high energy efficiency that operate with variable-flow refrigerant control. In these systems, the refrigerant flow rate is modulated according to the instantaneous load demand through inverter-controlled compressors and electronic expansion valves (EEV). Thus, independent capacity control is provided for each space, while the system's partial load performance is maximized. This feature provides significant energy savings, especially in large commercial buildings with constantly changing heat gains throughout the day.
VRF air conditioning systems have two main configurations: heat pump and heat recovery. Heat recovery VRF systems increase system efficiency by recovering waste heat thanks to their ability to provide both heating and cooling simultaneously in different zones. This plays an important role in reducing operating costs, especially in hotels, hospitals, shopping malls, and large office projects. System performance is evaluated through parameters such as COP, EER, and IPLV (Integrated Part Load Value).
VRF systems operate in integration with central building management systems (BMS - Building Management System), offering advanced automation, remote monitoring, and energy management capabilities. They can be easily adapted to architectural projects thanks to long piping distances, high elevation difference tolerance, and flexible indoor unit options. ASHRAE, ISO 5151, and Eurovent standards are important references that determine the performance and design criteria of VRF systems. Although the initial investment cost is high, VRF/VRV air conditioning systems are considered one of the most advanced technologies among modern central air conditioning solutions thanks to their high energy efficiency, flexible use, and long service life advantages.
VRF AIR CONDITIONING OUTDOOR UNITS
In VRF (Variable Refrigerant Flow) air conditioning systems, outdoor units are the most critical components that serve as the main energy generation and distribution center of the system. Thanks to inverter-controlled compressor technology, these units modulate the refrigerant flow rate according to instantaneous load demand and provide high energy efficiency. Today, VRF outdoor units are manufactured in two main configurations: full DC inverter or hybrid structure (approximately 50% DC inverter + 50% fixed-speed compressor). In full DC inverter systems, all compressors are variable speed, providing maximum efficiency under low-load conditions (high COP and IPLV), while in hybrid systems fixed-speed compressors are activated when high capacity is required, creating a cost-performance balance.
VRF outdoor units also have two main operating principles: heat pump and heat recovery. Heat recovery VRF outdoor units are capable of providing both heating and cooling simultaneously in different spaces. In these systems, heat energy extracted from one space is used to heat another space, thereby providing energy recovery. This significantly increases system efficiency and reduces operating costs. Such systems provide major advantages especially in hotels, hospitals, and mixed-use buildings.
Another important feature of VRF outdoor units is their modular structure and modular combination capability. Multiple outdoor units can be connected in parallel on the same copper piping line (refrigerant piping system) and operated as a single system. In this way, capacity expansion becomes flexible and high-tonnage systems can be created in large projects. These connections are generally carried out within the maximum capacity and piping limits specified by the manufacturers. In addition, this modular structure improves the system's partial load performance while preventing the entire system from being disabled in case of a failure, thereby ensuring operational continuity.
As a result, VRF air conditioning outdoor units are considered one of the most advanced technology components of modern HVAC systems with their high efficiency, flexible capacity expansion, advanced control capability, and energy recovery features.
TYPES OF INDOOR UNITS USED IN VRF / VRV SYSTEMS
VRF / VRV air conditioning systems are among the most flexible central air conditioning systems that can be customized according to the intended use of different spaces thanks to their wide range of indoor unit options. The indoor unit types used in these systems are determined according to architectural structure, ceiling height, air distribution requirements, acoustic comfort, and aesthetic expectations. In VRF air conditioning systems, indoor unit selection is a critical engineering parameter not only for comfort, but also for energy efficiency, air distribution homogeneity, and system performance. These units operate in synchronization with inverter-controlled outdoor units and provide independent temperature control in each space. The most commonly used indoor unit types in VRF air conditioning systems are explained below with technical details.

Cassette type VRF indoor units are advanced air conditioning systems integrated into suspended ceilings and providing homogeneous air distribution with their four-way airflow feature. These systems are preferred especially in commercial buildings such as offices, hotels, hospitals, and shopping malls. Thanks to the 360° air distribution principle, temperature gradients within the space are minimized and thermal comfort is maximized. Cassette type VRF indoor units provide effective air circulation even in large areas thanks to their high-airflow fan motors and optimized blade geometry.
In these systems, precise refrigerant control is generally provided by an electronic expansion valve (EEV), and acoustic comfort is maintained with a low noise level (dB). In addition, decorative panel options contribute to architectural integrity. VRF cassette type air conditioning systems are one of the most preferred indoor unit types in professional projects by offering energy efficiency and aesthetic solutions together.
DUCTED TYPE VRF INDOOR UNIT
Ducted type VRF indoor units are advanced climate control solutions that provide comfort closest to a central air conditioning system and allow completely concealed installation. In these systems, the indoor unit is positioned inside the suspended ceiling, and air is distributed to the environment through grilles via galvanized air ducts. In this way, homogeneous air distribution, low noise level, and high aesthetic standards are achieved.
Ducted VRF air conditioning systems are preferred especially in villa projects, luxury residences, hotels, and large office areas. One of the most important advantages of these systems is their suitability for fresh air integration. In addition, their fan structure with adjustable static pressure adapts to different duct lengths. With high comfort, low noise level, and central control advantages, ducted VRF systems are among the upper-segment solutions in professional HVAC projects.
WALL-MOUNTED VRF INDOOR UNIT
Wall-mounted VRF indoor units are compact and economical solutions that have the appearance of conventional split air conditioners while operating with VRF system infrastructure. These systems are designed for use in small and medium-sized spaces. Wall-mounted VRF air conditioning systems provide individual control and allow independent temperature settings in each space.
These units stand out with their low noise level and high energy efficiency. In addition, by operating in integration with an inverter-controlled system, they provide maximum performance under partial load conditions. They are preferred in offices, small commercial areas, and residential projects due to their ease of installation and maintenance advantages. Since they are used within a VRF system, central automation (BMS) integration is also possible.
CEILING TYPE VRF INDOOR UNIT
Ceiling type VRF indoor units are air conditioning solutions developed for areas where there is no suspended ceiling or where cassette type systems cannot be applied architecturally. These systems provide effective air circulation in large-volume areas thanks to their wide-angle air discharge capability and long-distance air throw.
Ceiling type VRF air conditioning systems are frequently preferred in restaurants, showrooms, gyms, and commercial areas. Thanks to their powerful fan structure and high airflow capacity, they provide rapid cooling and heating performance. In addition, airflow is optimized through adjustable louver structure. These systems operate in integration with VRF infrastructure and provide both central control and energy efficiency advantages.

They provide rapid and effective air distribution in large areas thanks to their high airflow rate and powerful fan structure.
Floor-standing VRF air conditioning systems operate by being mounted on the floor and stand out with their wide-angle air discharge capability. However, in projects with high aesthetic and hygiene requirements, they are generally used as supporting systems. By operating in integration with the VRF system, they offer the advantages of central control, energy management, and high efficiency. With these features, floor-standing VRF indoor units stand out as a powerful air conditioning solution in large-volume commercial areas.
DX HEAT RECOVERY INDOOR UNITS
A heat recovery ventilation unit with a DX coil is an advanced HVAC solution used to meet fresh air demand, improve indoor air quality (IAQ - Indoor Air Quality), and increase energy efficiency. The basic principle in these systems is to pre-condition the fresh air taken from outside by recovering heat from the exhausted polluted air. The heat recovery process is generally carried out through plate heat exchangers or rotary type heat exchangers (enthalpy wheel). In this way, the outdoor air load is significantly reduced and the total energy consumption of the system is decreased.
In ventilation units with DX coils, after heat recovery, fresh air is passed over a direct expansion (DX) coil connected to the VRF system and subjected to precise temperature and humidity control. This DX coil provides high-efficiency heat transfer through the direct expansion of the refrigerant and offers a faster response time compared to conventional water-based systems. Especially under variable load conditions, fresh air conditioning is kept at an optimum level thanks to the modulation capability of the DX coil.
These systems are widely used in areas with high fresh air demand, such as offices, hospitals, cleanrooms, and commercial buildings. While the ASHRAE 62.1 standard defines indoor air quality requirements, Eurovent certification is an important reference for verifying system performance. Heat recovery ventilation units with DX coils are professional systems that stand out among sustainable HVAC solutions due to their high energy efficiency and low operating cost.
HEAT RECOVERY VRF AIR CONDITIONING SYSTEMS
Heat Recovery VRF Air Conditioning Systems are advanced central climate control systems that allow simultaneous heating and cooling in different spaces within the same building. Unlike conventional Heat Pump VRF systems, Heat Recovery VRF systems provide energy recovery by using the cooling energy generated in one space for heating another space. Thanks to this feature, system efficiency is significantly increased and operating costs are reduced.
Heat Recovery VRF systems, which are particularly preferred in hotels, hospitals, business centers, residences, shopping malls, airports, and mixed-use commercial buildings, can meet the heating and cooling demands that change throughout the day in buildings with different facades. While a space on the northern facade may require heating, a space on the sun-exposed southern facade may require cooling. Heat Recovery VRF technology meets these different requirements through a single system and provides maximum energy efficiency.
Modern Heat Recovery VRF systems are among today's most efficient climate control solutions thanks to advanced inverter compressor technologies, intelligent control systems, and building automation integrations.
OPERATING PRINCIPLE OF HEAT RECOVERY VRF SYSTEMS
In Heat Recovery VRF systems, the outdoor unit, indoor units, and special branch selector boxes (Branch Selector Box - BS Box) operate together. The refrigerant circulating within the system is directed according to the operating mode of the space requiring conditioning.
When cooling is performed in one space, the heat energy extracted from the environment is recovered within the system instead of being discharged to the outdoor environment, and is used to heat another space. Therefore, the system can provide both heating and cooling at the same time.
For example, in a hotel, rooms on the sun-exposed facade may operate in cooling mode while rooms on the shaded side may operate in heating mode. The Heat Recovery system transfers the energy it obtains from the rooms being cooled to the rooms being heated, thereby providing energy recovery.
Thanks to this operating principle, compressor load is reduced, electricity consumption decreases, and the system's COP and EER values increase significantly.
EQUIPMENT USED IN HEAT RECOVERY VRF SYSTEMS
HEAT RECOVERY VRF OUTDOOR UNIT
The Heat Recovery VRF outdoor unit is the main energy center of the system. It contains inverter-controlled compressors, condenser coils, electronic expansion valves, and advanced control boards. The outdoor unit manages the capacity of the entire system and enables energy transfer between indoor units.
New-generation outdoor units use DC Inverter Scroll Compressor technology. Thanks to this technology, the compressor speed is automatically adjusted according to capacity demand, and unnecessary energy consumption is prevented. In Heat Recovery systems, outdoor units provide high partial load efficiency and deliver significant energy savings, especially in large projects.
BRANCH SELECTOR BOX (BS BOX)
The BS Box, or Branch Selector Box, is one of the most important pieces of equipment in Heat Recovery VRF systems. Thanks to this equipment, each indoor unit can operate independently in heating or cooling mode.
The electronic valves and routing equipment inside the BS Box send the refrigerant to the relevant indoor units in the required mode. Unlike Heat Pump VRF systems, the BS Box system is the main equipment that enables different operating modes to be available simultaneously in Heat Recovery VRF systems.
VRF INDOOR UNITS
Cassette type, ducted type, wall-mounted type, floor-standing type, and ceiling type indoor units can be used in Heat Recovery systems. Different indoor unit types are selected according to the intended use and architectural structure of each space.
Indoor units provide precise capacity control through electronic expansion valves and maintain the space temperature at the desired value. They increase user comfort thanks to their low noise levels and high energy efficiency.
INVERTER COMPRESSORS
Inverter compressors continuously adjust system capacity according to demand. They provide much lower energy consumption compared to conventional on-off operating systems.
Continuous modulation of the compressor speed reduces temperature fluctuations, increases user comfort, and extends equipment service life.
CENTRAL CONTROL AND AUTOMATION SYSTEMS
Heat Recovery VRF systems have advanced automation infrastructures. Thanks to central control panels, hundreds of indoor units can be managed from a single point.
Systems can be connected to building automation systems through BACnet, Modbus, LonWorks, and BMS integrations. Energy monitoring, remote access, alarm management, and performance reporting operations can be carried out centrally.
ADVANTAGES OF HEAT RECOVERY VRF SYSTEMS
Heat Recovery VRF systems are among the central climate control solutions with the highest energy efficiency today. Thanks to their ability to provide both heating and cooling simultaneously, they offer significant advantages especially in buildings with different usage requirements.
Energy recovery is achieved by using the energy obtained from cooled spaces in areas requiring heating, and electricity consumption is significantly reduced. This reduces operating costs while also lowering carbon emissions.
In addition, user comfort is increased to a high level because each space can be controlled independently. These systems are frequently preferred in hotels, residences, and office projects because they offer the advantages of central systems while also providing individual control.
Low piping costs, long piping distances, flexible architectural solutions, low noise levels, and high automation capability are among the other important advantages of Heat Recovery VRF systems.
APPLICATION AREAS OF HEAT RECOVERY VRF SYSTEMS
Heat Recovery VRF systems are used especially in buildings where heating and cooling demands occur at different times or simultaneously within the same building.
Hotels, hospitals, shopping malls, business centers, residences, plazas, educational buildings, airports, public buildings, and mixed-use projects are the most common application areas of these systems.
Especially in projects targeting LEED, BREEAM, and sustainable building certification, Heat Recovery VRF systems provide significant advantages due to their high energy efficiency. Considering that energy costs are continuously increasing today, Heat Recovery VRF systems stand out as a long-term and sustainable climate control solution for both investors and operators.
MAINTENANCE AND SERVICE WORKS IN HEAT RECOVERY VRF SYSTEMS
Regular maintenance is required for Heat Recovery VRF systems to operate with high efficiency. Within the scope of periodic maintenance works, indoor unit filter cleaning, evaporator cleaning, condenser cleaning, refrigerant pressure checks, leak tests, electronic board checks, sensor calibrations, and communication infrastructure checks are carried out.
Thanks to the maintenance works performed by ASROYAL technical service teams, system performance is maintained, energy consumption is optimized, and potential failures are detected before they occur. Regular maintenance practices extend system service life while significantly reducing operating costs.
