The basic method of central air-conditioning maintenance of: 1, regular cleaning the air filter. Cleaning time usually 2-3 weeks. The steps are: Remove the panel; extract air filter; clean air filter. The air filter on the rinse under the tap, as the filter with plastic frame and polyester filament repression central air conditioning installation, so we can not use more than 40 ℃ hot water central air conditioning Which is better, to prevent shrinkage. After cleaning the filter net of the water can be drying, insert panel central air-conditioning company, installed air conditioning. 2, the protection of the condenser and evaporator fins. The condenser and evaporator fins is 0.15 mm after aluminum expander set into the brass made, it can not withstand a collision, if damaged fins (rewind), will affect the cooling effect of air conditioning, refrigeration reduced efficiency. Therefore, pay special attention to protecting. 3, protect the cooling system. If damaged parts or connecting pipe cooling system, it will cause a refrigerant leak, the air conditioner will not be cooling. 4, the correct selection of fuse (fuse). By product specification indicated nominal current fuse specifications, can not afford the insurance effect is too large, too small, often blown. 5, the air conditioning manual stop, open operating time, should every 2 minutes, can not continuously stop, start. In recent years, with the urbanization construction and real estate market, and commercial housing transaction volume has increased steadily. While residents' demands for a comfortable life is becoming strong, central air conditioning awareness continues to improve, the proportion of fine decoration Chengpinfang significant improvements in recent years. Thereby pulling the home central air-conditioning applications in the residential decoration market, which is driving the direct cause of home central air conditioning domestic market sustained growth. Ovid Consulting data show that in 2013 China market size of home central air conditioning is about 40 billion yuan, the central air conditioning has been widely used in high-end residential and villa projects. Jiangsu and Zhejiang Provinces of new homes currently for home machines such home central air conditioning unit, and has accounted for 70%. With China's economic development, home central air-conditioning market will show rapid growth, it has been widely used in high-end residential and villa projects. Next 8--10 years, China Central Air Conditioning annual market growth rate will remain at 20%. China has been a split type air conditioner market dominated Guiji, window machine hegemony pattern.
