2, cleaning services program air system: 2.1 Air Systems Cleaning reason: Most commonly used in central air-conditioning systems coarse filter, air filter out up to 40 percent of respirable particulate matter, more than half of respirable particulate matter will enter central air conditioning system. On the one hand refrigeration plant, these respirable particulate matter may become carriers of the virus, the virus in the air duct flow propagation, resulting in cross-infection; on the other hand, small particles of respirable particulate matter interconnected become a big dust accumulated in the air duct The bottom and corners, over the edge breeding microorganisms (such as Legionella). Wind systems exist with these viruses and microbes ease of duct was sent around the indoor refrigeration equipment parts, will cause secondary pollution of indoor air, which people live and work environment and long-term hazards of second-hand refrigeration equipment, cause reduced efficiency, and prone to respiratory diseases. Therefore, it is necessary to periodically conduct a thorough cleaning and disinfection of air system work. 4 chiller maintenance, if not an emergency case not by cutting off the main power supply to shut down the unit; if the crew to stop using winter long, then turn off the unit, and then turn off the main power supply of refrigeration equipment, water and exhausted within the system. 5, to keep the room clean and well-ventilated, in addition to regular cleaning of the condenser masonry work to ensure stable operation of the unit normal.
