Caidian air conditioning receive fluorine 1.1 machine should be preceded by the liquid refrigerant within the air conditioner outdoor unit of income. 1.2 collect fluid steps: first air conditioning unit in a cooling state, and start running. 1.3 The high-pressure valve on the outdoor unit hexagonal brass valve cover is opened with a hex wrench high-pressure valve is closed, (on one side of the outdoor unit only has two-way valve, a large diameter low-pressure valves, one small diameter high pressure valve). 1.4 At this time the air conditioner is still running because the high pressure valve has been closed, so the cooling fluid can no longer flow through the high-pressure valve of the indoor unit heat exchange, and is compressed into the outdoor unit. 1.5, etc. runs about 3-5 minutes, the indoor unit should no longer have air conditioning blowing, instructions have been received all the liquid refrigerant in the outdoor unit. 1.6 At this low-pressure way valve is turned off and then the outdoor unit. At this time it was closed liquid refrigerant in the outdoor unit in the. 1.7 The air conditioning is turned off. 1.8 In this case can be disassemble operation, connecting pipeline to remove indoor and outdoor unit, remove the cable between indoor and outdoor unit 1.9 Remove Unicom brass pay attention to clean, with a plastic bag to pipe outlet and three-way valve interface They are sealed. Hanyang air conditioning repair with the rising popularity of home appliances, air-conditioning usage is gradually improving, but at the same time spread a large area, problems arising in the use of home appliances is also another. Some friends will ask, why not heating air conditioning at home? How to clean the filter? How much air conditioning effect for many reasons caused by poor air conditioning repair air conditioning ineffective, specifically, roughly 10 aspects of the following reasons: (1) lack of refrigerant in the system; (2) System slight blockage; (3) the machine filter dirty; (4) unit heat sink dirty; (5) the thermostat is faulty; improper (6) temperature settings; (7) the fan speed is too slow; (8) Air conditioning power does not match; (9) Cooling Too many agents; (10) supply voltage variations;
