MECHANICAL INSTALLATION SYSTEMS IN THE HEALTHCARE SECTOR
Healthcare facilities such as hospitals, medical centers, medical faculties, research hospitals, and laboratories are among the buildings where mechanical installation systems are used most intensively and critically. In these facilities, parameters that directly affect human health, such as temperature, humidity, air quality, pressure control, sterilization, and energy efficiency, are of great importance. HVAC systems, cleanroom systems, medical gas installations, central air conditioning systems, fire extinguishing systems, and building automation systems used in healthcare facilities are designed in accordance with international standards. Mechanical installation systems used in hospitals are designed and implemented in compliance with many technical standards, primarily ASHRAE, HTM, DIN, EN, ISO, NFPA, and TSE standards.
VENTILATION SYSTEMS IN HOSPITALS
Hospital ventilation systems are among the most critical mechanical installation systems in terms of patient safety and infection control. Ventilation systems used in hospitals are designed according to different criteria for operating rooms, intensive care units, isolation rooms, laboratories, imaging centers, sterile areas, and general-use areas.
HEPA filters, pre-filters, bag filters, UV sterilization systems, and high-efficiency fans are used in these systems. Air change rates are determined according to ASHRAE and HTM standards, and 20–25 air changes per hour can be provided in operating rooms. While positive pressure areas protect sterile zones, negative pressure isolation rooms prevent the spread of infections.
In hospital ventilation systems, air handling units, VAV systems, CAV systems, duct installations, silencers, fire dampers, and automation-controlled air distribution equipment are used. In addition, plate-type or rotary-type heat recovery systems are applied for energy saving purposes. In modern healthcare buildings, ventilation systems not only provide comfort but also serve as one of the most important components of infection control.
HEATING SYSTEMS IN HOSPITALS
Heating systems in hospitals are designed to maintain patient comfort and ensure uninterrupted medical processes. Heating systems used in healthcare buildings consist of central boiler systems, condensing boilers, hot water installations, radiator systems, fan-coil systems, underfloor heating systems, and heating coils of air handling units.
Different temperature values are determined for operating rooms, intensive care units, laboratories, and patient rooms. For this reason, zone-controlled heating systems are preferred. Hot water installations used in hospitals are generally designed with dual pumps and backup systems to ensure energy continuity.
High energy efficiency is achieved through frequency-controlled pumps, three-way valves, balancing valves, manifold systems, and automation integration used in heating systems. Especially in large-scale city hospitals, electricity, heat, and cooling energy can be produced together by using cogeneration and trigeneration systems.
COOLING SYSTEMS IN HOSPITALS
Cooling systems ensure that stable temperature and humidity conditions are maintained throughout the year in hospitals. Operating rooms, MRI rooms, tomography centers, intensive care units, laboratories, and pharmaceutical storage areas are particularly sensitive areas that require precise air conditioning.
Air-cooled and water-cooled chiller systems are widely used in hospitals. Chiller systems operate in integration with fan-coil units, air handling units, and precision-controlled cooling systems. Primary-secondary pump systems, frequency inverters, automatic balancing valves, and high-efficiency plate heat exchangers are used in cooling installations.
In order to increase energy efficiency, free cooling, variable flow pumping systems, and heat recovery chiller technologies are preferred. In critical healthcare areas, temperature and humidity parameters are continuously monitored and controlled through the building automation system.
CLEANROOM SYSTEMS IN HOSPITALS
Cleanroom systems are special HVAC applications used in the most sensitive departments of hospitals. Operating rooms, hybrid operating rooms, organ transplant centers, sterile production areas, and some laboratories are designed according to cleanroom standards.
In these systems, HEPA H13 and HEPA H14 filters, terminal filter boxes, laminar flow units, and special air distribution systems are used. In cleanrooms designed in accordance with ISO 14644 and GMP standards, particle counts are continuously monitored.
Thanks to laminar flow systems, unidirectional sterile air flow is created over the operating table. With positive pressure control, contaminated air entry from the external environment is prevented. Temperature, humidity, and pressure values are continuously monitored and recorded through the automation system.
Cleanroom systems are of great importance in terms of reducing infection risk, increasing surgical success rates, and ensuring maximum hygiene in healthcare services.
CENTRAL AIR CONDITIONING SYSTEMS IN HOSPITALS
Central air conditioning systems are advanced HVAC solutions that can manage all air conditioning needs of hospitals from a single center. In these systems, air handling units, chiller groups, fan-coil units, VAV boxes, air ducts, and automation systems operate together.
Thanks to central air conditioning systems, temperature, humidity, air quality, and pressure parameters are kept under continuous control. Precise air conditioning is provided especially for operating rooms, intensive care areas, and laboratories.
For energy efficiency, high-efficiency EC fans, frequency-controlled motors, heat recovery systems, and smart automation applications are used. In large-scale healthcare campuses, central air conditioning systems reduce energy costs while also providing ease of maintenance.
FIRE PROTECTION INSTALLATION SYSTEMS IN HOSPITALS
Fire protection installations are one of the fundamental elements of life safety in hospitals. Fire systems used in hospitals are designed in accordance with NFPA, EN 12845, and relevant local regulations.
These systems include sprinkler systems, fire cabinets, hydrant systems, fire pumps, foam extinguishing systems, and gas extinguishing systems. FM200 or inert gas extinguishing systems can be used in electrical rooms, UPS rooms, and data centers.
Mechanical fire protection installations integrated with fire detection systems are automatically activated in emergency situations. Smoke control systems and stair pressurization systems increase evacuation safety. Fire systems in hospitals are designed with backup systems to ensure uninterrupted operation.
BUILDING AUTOMATION SYSTEMS IN HOSPITALS
Building automation systems (BMS) enable centralized control of all mechanical installation equipment in hospitals. Air handling units, chillers, boilers, pumps, fans, cleanroom systems, and energy monitoring systems are connected to the automation infrastructure.
Thanks to BMS systems, temperature, humidity, differential pressure, energy consumption, and equipment performance are continuously monitored. In the event of a malfunction, instant alarms are sent to operators.
SCADA and PLC-based automation systems provide energy savings while also reducing maintenance costs. Especially in city hospitals, thousands of mechanical equipment can be managed from a single center.
MEDICAL GAS SYSTEMS IN HOSPITALS
Medical gas systems are among the most critical mechanical infrastructures of hospitals. These systems ensure the safe distribution of gases used in patients’ life support processes.
Medical gas installations include oxygen (O₂), vacuum, medical air, nitrous oxide (N₂O), carbon dioxide (CO₂), and nitrogen (N₂) lines. The systems are installed with copper pipes, and special welding techniques are used.
Central gas stations, manifold systems, vacuum pumps, compressor stations, and alarm panels are the main components of medical gas systems. All systems are designed and certified in accordance with HTM and ISO 7396 standards.
PNEUMATIC TUBE TRANSPORT SYSTEMS IN HOSPITALS
Pneumatic tube transport systems are automatic logistics systems that ensure the rapid transportation of laboratory samples, blood products, medicines, medical documents, and small medical equipment in hospitals.
In these systems, special transport capsules, PVC or steel pipe lines, high-speed blower systems, routing stations, and central control software are used. The transport process is carried out based on the principle of vacuum and positive pressure.
Thanks to pneumatic systems in modern hospitals, laboratory result times are shortened, staff workload is reduced, and operational efficiency is increased. Especially in large city hospitals, hundreds of stations can operate on the same network.
Pneumatic tube systems have become an indispensable part of hospital logistics and significantly increase the speed and quality of healthcare services.
