In everyday life, the appliance is probably the most common problem is the use of second-hand air-conditioning installation of Xuzhou, in the event tends to make us helpless. Particularly complex home appliances, such as air-conditioning appliances such a problem will make us know what to do. Today, it gives us some air conditioning problems should do the inspection. Families with air conditioning friends might often used together to understand. (1), drain: refers to refrigerant leakage; electrical (wiring, body) leakage and other damage caused by the insulation. (2), block: refers to fouling and plugging the ice refrigeration system; air filter is clogged; air inlet and outlet are an obstacle blockage. (3) off: an electrical line break; fuse blown; due to overheating or excessive current overload caused by the contact is open; the cooling system pressure caused by abnormal pressure switch contact is opened and the like. (4), burn: refers to the compressor motor windings, fan motor windings, solenoid coils, relay coils and contacts, etc. are burned. (5), the card: a compressor means jammed, jammed fan, moving parts of bearings jam. (6) damage: broken finger compressor valves, piston scuffing, fan blade fracture and various parts breakage. The company reminds you're looking for professional repair air conditioning maintenance master! Wedding dresses four caveats air conditioning process moves sideways, you need to pay attention to a lot of questions, particularly, the following stations are wedding dresses summary exceptionally important to note local, as follows: First, the income received fluorine fluorine can say is the most important local second-hand air conditioning, because the air conditioning refrigeration power play, shut down the compressor operation pressure valve (with a hex close the outdoor unit small brass) job for a minute and then close the low pressure valve (outdoor unit large brass), stop . Unplug the power cord. Exceptionally important to note that must unplug the power plug. Second, remove the indoor and outdoor unit three, open the outdoor unit Copper Pipe Fittings (plastic sheeting wrapped into the soil to avoid), open outdoor electromechanical cable connector (particularly need to remember the line sequence) Fourth, same time be installed The first to open the outdoor unit small brass, with a little bit of air blowing fluorine indoor unit (10 seconds), then turn off the big brass. Thus there will be no air in it (evacuation is needed particularly to note) Chunlan a boot on the trip can detect the presence of air conditioning capacitor is not a breakdown or short questions Xuzhou hand air conditioning recovery, then testing whether the inter-turn short circuit fault Chunlan. Chunlan a boot on the trip cause of the malfunction and repair methods: 1, the detection Chunlan compressor launch capacitance is not failure; repair or replace. 2, testing Chunlan is not present insulation aging, short questions: high temperature after the air conditioning operation due to short circuit between turns representation; view sweep. 3, Chunlan belong rational load, sudden current compressor when the engine is greater than the rated current of the protection device and lead Chunlan a boot on the trip doubt; replace rated current greater protection. 4, the electricity peak period, the voltage is low, Chunlan compressor current becomes large, resulting in trip condition air conditioning; avoid peak hours of electricity use or devices regulated pumps. 5, the air conditioning unit is dirty condenser fins form the heat load is too high; timely to Chunlan condenser cleaning. 6, to remove the above reasons, it shall detect Chunlan air-conditioning compressor is not damaged; timely repair or replacement.
