Many users want to buy central air condition and water chiller, but do not know about air-conditioning and water chiller cooling professional knowledge, so they do not have confidence in purchasing air-conditioning and water chiller equipments.
If you are not a professional purchaser, you may be confused by the professional vocabulary of air conditioning by the salesmen. Even if you buy the right air conditioner, but in the process of using some problem will comes because you do not know the air conditioner or chiller professional knowledge. You can not help but spend money to ask professionals to solve, but in fact, the problem is not complex, you may be able to solve it by yourself, but you do not understand what’s happening.
The following article is the most basic refrigeration knowledge, let you understand the principle of air conditioning or chiller refrigeration, let's started!
Cooling circuit and Basic refrigeration system
Air conditioner has 4 main parts: Compressor, condenser, evaporator and liquid refrigerant control device.
For example please check the above cooling circuit principle diagram , this system is totally same as the split air condition used in your home.
Compressor is the heart of refrigeration system. Compressor compresses refrigerant into high-temperature and high-pressure gas. High-temperature and high-pressure gas will enter the condenser.
Condenser distributes heats to air or water to reduce the temperature and pressure of refrigerant. After that, refrigerant will pass through liquid refrigerant control device, generally is expansion valve. Expansion valve will change refrigerant into low-temperature and low-pressure liquid, the low-temperature and low-pressure refrigerant will flow through the evaporator, which releases the cooling heats of the refrigerant into the air or water, and the cold air or water is used to cool our room or industrial process.
Finally, the refrigerant releases the cooling energy and absorbs the heats from the outside evaporating into the low temperature and low pressure gas. Finally, the refrigerant returns to the compressor for another compression process, so the cycle reciprocates, forming a refrigeration cycle.
Wish this article can help you to improve the central air conditioning system .
