Different air-conditioner maintenance method

different methods of air-conditioner maintenance in the air-conditioner market, air-conditioner refrigerant there are two basic types, one is without freon, one kind is with freon. Then the two freezers when fault occurs, the maintenance method is the same? The answer is not the same, then we will combined with living example, to tell you how no freon air-conditioner maintenance. Non-fresno freezers R134a has a refrigeration system, to maintain absolute dry in normal work, freezers minor repairs, want to see, ear to listen to and hand touch, careful analysis and accurate judgement, blocking can confirm the fault for the filter drier, or compressor is bad, need to open the system, disconnect the pipe mouth shall timely sealing, welding also want to quickly, especially in the compressor repair process pipe is put into a three-way valve, charge the hose after loading with refrigerant steel cylinder valve connection, want to use the same kind of working medium gas internal cavity pressure leak detection, ensure good air tightness, fast repair, opening time is shorter, all operation is not greater than 20 minutes. When in operation, is a tricky opening decision, pipeline once cracked, there will be water and debris into the system. Above is a little fault, so if it is big trouble? So how to operate? The following methods to share with you. Overhaul refers to the commercial freezer of leakage fault, need to drive back to repair, move hand, cleaning refrigeration system to irrigate with everything, everything is also available gas pressure leak detection, repeatedly filling again, after passing out everything method instead of time, especially in the leak appeared on the low voltage side of the compressor, it is best to replace the compressor. Every dynamic system line, must be replaced is the filter drier, capillary inserts and ordinary freezers are basically the same, if with soap and water leakage, low pressure test shall be carried out after the outage pressure balance, maintenance actions must be quick, pay attention to ready before opening line, prepare tool material, the complete process of no more than 50 minutes, or air-conditioner repairing quality cannot be guaranteed. These are the basis of method, if not to find a professional company to repair such as the snow of air-conditioner.
