Combined air conditioner It is modern and advanced air conditioner The equipment is relatively simple in use and operation, and can effectively solve the indoor air pollution, but you must understand some details of the use and maintenance of the combined air conditioner, which will help improve the performance of the equipment.

Combined air conditioner The team shall be managed by a specially assigned person. During operation, the operation of the unit shall be checked regularly, and any abnormality found shall be eliminated in time. The unit shall be fully maintained after 2-3 years of operation. Chemical removal Heat exchanger Wash the fins of heat exchanger with compressed air or water for scale inside. The air filter must be cleaned regularly, and the interval between two cleanings depends on the use environment. It shall be replaced when the final resistance reaches 2 of the initial resistance. The orifice plate of the micro perforated plate muffler shall be blown with compressed air every quarter to prevent the surface dust from blocking the small holes and reducing the noise elimination effect. Frequently check the water spraying section, check whether the floating ball has faults, whether the water filter network is complete, whether the nozzle is blocked and whether it needs cleaning. Regularly check the electrical equipment of the unit to ensure that there is no leakage. When the unit is shut down temporarily or for a long time in winter, the fresh air valve shall be closed; If the machine needs to be shut down for a long time, the water in the heat exchanger shall be drained to prevent the heat exchanger from freezing. When starting the unit in winter, start the water first pump , and then open the fresh air valve; During shutdown, the fresh air valve shall be closed first, and then the water pump shall be closed. When the air duct of the combined air conditioning unit is not connected to the load, the air outlet should be blocked by about 3/4 to prevent burning electric machinery 。 The flow rate of cold (hot) water in the heat exchanger should be adjusted to 0.6~1.8m/s, and its working pressure should not exceed 1.2MPa. Combined air conditioner The refrigerant used in Group A is low-temperature chilled water (5-7 ℃), and the hot coal is hot water (60 ℃). The water quality should be softened.

For the use and maintenance of equipment, we should pay attention to many aspects, and it is impossible to list them one by one. We can only talk about the common problems that need special attention. In addition, we should also pay attention to summing up experience, reducing the occurrence of problems and extending the service life of equipment.
