If the air conditioner is re assembled, will it damage the copper tube?
1. Fluoride collection. Turn on the machine and refrigerate. After the compressor works, turn off the high pressure valve, run for one minute, turn off the low pressure valve and stop the machine. Unplug the power plug (remember!!!!!!!!)!2, outdoor machine brass fittings (plastic cloth, to prevent the soil), outdoor electrical connector (remember line order)3. Remove the indoor and outdoor units.Loading machine:1, according to the position of the indoor machine tube wall play: in a predetermined position hanging plate nail of the indoor machine (must ensure the level, the level of instrument calibration), the pipe is penetrated out after hanging indoor machine;2, according to the length of the pipe to determine the location of outdoor machines, outdoor machines should also ensure that the level;3, connect high and low pressure pipe, first open high pressure valve, and then loose low-pressure pipe lock mother (exhaust pipe air), hear the voice of the vent, 8~10 seconds later, the lock mother, open the low pressure valve, in order to connect the wire.4. Switch on the power and test the machine. Check the joint (lock) with soap water for leaks.Note: 1. old air conditioning copper poor toughness, easy bending die into laos;2. take fluoride and exhaust air thoroughly;3., internal and external confidential level, firm, otherwise loud noise;4. there is no leakage.These are personal experiences that I hope will help you. In addition, the above procedure is only applicable to summer (the working condition of air conditioner is refrigeration)
Influential。 Depending on the location of the copper tubes, the effect on the air conditioning is different.When the air conditioner indoor and outdoor machine connecting copper pipe bend, air conditioning and refrigeration system piping "pressure loss" will become large, from the compressor working point, variable pressure loss large led directly to the air conditioning compressor capacity output of small systems, such as air conditioning compressor is 2 horsepower capacity, due to internal and external connecting pipe bending machine fold to a certain extent lead to evaporation pressure air conditioning system is reduced, the compressor habit pressure is reduced, the corresponding proportion of the output capacity of the compressor capacity may become smaller, 1.8 horses or even lower number of horses compressor value.When the air conditioner indoor and outdoor machine bending connecting copper pipe to a certain extent, if we can repair the best, it can not be repaired, can only replace the connecting copper pipe or the bending place on both sides are connected by pipe cut to brazing.
Air conditioning pipe to minimize the number of disassembly and disassembly often has some damage, (brass of the demolition more hard, easily broken, sharp anti disk attention circle).
