Basic knowledge of air energy

At present, the most commonly used vapor compression heat pumps, compressors, evaporators, condensers, and throttle valves are the four main components. Other auxiliary components include fans, four-way valves, liquid storage tanks, gas-liquid separators, copper pipes, and Protectors and electronic control parts used to ensure the normal operation of the machine, etc. Direct-heating models also include a water flow regulating valve.

How to solve if the air conditioner is not cooling

If it is not in the cooling state, we can adjust it to the cooling mode; if the dust accumulation of the air conditioner severely reduces the cooling function, we can find professional personnel to disassemble the evaporator, fan blade, and filter. Completely clean up; if it is because no refrigerant is added, then we can add refrigerant.

Which is better, semiconductor refrigeration and compressor refrigeration

Which is better, semiconductor refrigeration and compressor refrigeration <img src="{{media url=&quot;o4YBAF3LcwuAC1ILAAEzxLDPcHA979.jpg&quot;}}" alt="" />Semiconductor refrigeration 　　Semiconductor refrigerator refers to a device that uses the thermo-electric effect of semiconductor to produce cooling capacity, also known as thermoelectric refrigerator. Connect two different metals with conductors, and connect direct current, then the temperature at one contact will decrease and the temperature at the other contact will increase.
