The copper tube is cold. Why doesn't the air conditioner give the cold air?
The summer air conditioning unit in operation, in a constant flow of circulating refrigerant tube, in order to achieve the purpose of cooling air conditioner, if your time for a long time or not will be brass with thermal warm bag, brass exposed in the air, then the hot weather and the formation of anti poor outdoor copper, will be condensed into water if the pressure is not enough, lack of freon, the compressor will be more difficult, generally a frost in the brass nut, which is typical of the lack of air conditioning freon, outside the machine copper frost tract symptoms, suggest to add freon, and check out the bare copper, because it will greatly reduce the cooling effect. A: the obvious lack of fluoride does not add to the compressor! If too much fluorine leakage that leak air conditioning pipeline leak leak after you!! plus fluoride! Or after adding the time not long! This is the structure of air conditioning appliance two is a machine (evaporator, condenser, compressor) is the basic working principle of the heat from moving in electric drive from outdoor to indoor. In winter, summer in.B: if the outdoor temperature is too low, for example, to ten degrees below zero and low heat.
When the heat is not little, cocoa moved much. Air conditioning effect is not obvious...C recommends that you use electric heating air conditioning: This is a lack of snow, with you the pressure gauge pressure, if not up to the pressure, we must add a snow, at the same time to check and see if there is no place to leak, leak, to be repaired, otherwise a snow added is almost all.D: air conditioning pressure Guan Jieshuang: 1: 98% The fault is refrigerant shortage. For this reason 99% is to install the problem!!! Check the connection pipe it has received!!! If the installation process has extended the connection tube should check the welding have trachoma!! if the installation process is reduced at the length of the connecting pipe on the weight check our expansion is qualified! 2: 0.5% is the quality of the machine itself caused by leakage, which requires professional maintenance maintenance inspections! 3: 0.5% machine is capillary clogging caused by the fault for the performance of the air conditioning pipe frosting machine capillary also appear frost, the current boot from the start all the way until the rise.
Overheating of the compressor shutdown!!! Released after the replacement refrigerant capillary can be solved! If the electronic expansion valve with the check the electronic expansion valve is no fault!!! If there is no problem in the proposed replacement pipe temperature thermistor, because it will be The opening and closing degrees of the electronic expansion valve are unknown factors of 4:1% E: Freon is circulated in the heat pipe under the motion of the compressor, and the internal heat is passed through the Freon, and the refrigerant is circulated repeatedly to the outside. The lack of fluoride, too little Freon enter, in the form of liquid flow can be a high pressure pipe, and rapid vaporization, while absorbing the high-pressure pipe near the heat, water vapor cooling and high pressure pipe external to a certain temperature and frost; while the normal amount of freon in the high-pressure pipe section is still liquid circulation, high temperature pipe will not decrease rapidly.
