The role of air conditioning is extremely significant, and it must absolutely not malfunction during operation. Otherwise, it could impact the health of patients. Therefore, the cleaning of central air conditioning units becomes especially crucial!

Central Air Conditioning Cleaning

Terminal equipment should have a scheduled maintenance plan established.

2. During the operation of the central air conditioning system, the internal surfaces of the air disinfection unit, filters, heat exchanger coils, condenser plates, and air handling equipment boxes should be tested every two months. The detection results of biological pollutants should meet the surface hygiene standards specified in GB 50365. When the air conditioning and ventilation system is in operation, it should comply with the surface hygiene standards for objects. Disinfection should be carried out when there are biological pollutants, and this should be done when the air conditioning and ventilation system is stopped. The disinfection method should be carried out according to the requirements of WS/T 396.

Within 7 days after the central air conditioning system is cleaned and disinfected, the air handling equipment, filters, heat exchanger coils, condensate trays, and air disinfection devices on the interior surfaces of the equipment should be retested for sanitation. Test results must comply with the cleaning and disinfection requirements of WS/T 396.

4. Establish your own air filter inspection, cleaning, disinfection, and replacement schedule based on local environmental conditions and usage frequency.
