The requirements for hospital operating theaters include stringent control over temperature, humidity, cleanliness, airflow velocity, direction, and air quality to ensure the safety and efficiency of surgical procedures. Frimec's solution involves the integration of a stable chiller with a third-generation purification air handling unit to create a consistently clean and sterile environment.

The system design shall encompass the following aspects: an independent temperature and humidity control (dual cooling source) system, employing air-cooled (variable frequency) chillers in conjunction with medical-grade air conditioning units specifically designed for clean operating rooms, to achieve precise control over temperature and humidity within the operating room. This system eliminates the counteraction of cooling and heating during summer, resulting in lower energy consumption. Filter: The clean air conditioning unit is equipped with a comprehensive set of filters; its internally smooth surfaces and rounded corners effectively prevent dust accumulation. The dry-type antibacterial water tray and coil inhibit the growth of bacteria, prevent internal water accumulation, and possess antibacterial properties. These features fundamentally disrupt the chain of microorganism growth and transmission, ensuring the safety of the medical environment and preventing secondary pollution and microbial growth within the air conditioning system.
