This small series from "what is a refrigeration compressor" and "key performance indicators of the refrigeration compressor" two ways to share knowledge, to spread out the refrigeration compressor.
1 What is a refrigeration compressor
Compressor is used to increase the gas pressure and gas transportation machinery,used in chiller and heat pump compressors are called refrigeration compressors.
Compressors in the system as follows: suction refrigerant vapor from the evaporator, and raise its temperature and pressure, put it into the condenser. In the condenser, high pressure thermal condensation of refrigerants at condensation temperatureof superheated steam down. Then through the throttling element, step down after gas-liquid mixture flows to the evaporator, where the liquid refrigerant at evaporation temperature heat to boil, steam back into the compressor, enables the constant circulation of the refrigerant in the refrigeration system. Therefore, compressor system of "heart".
2 key performance indicators for refrigeration compressor
Cooling capacity
Compressor working ability to visually represented by arising out of cooling capacity per unit of time, it is one of the most important performance of refrigeration compressors.
Electric power
Input power is consumed by the compressor motor electric power.
Energy efficiency ratio
To ultimately measure the compressor power and budget, using the coefficient of performance COP (Coefficient of performance), under certain conditions it is compressor refrigerating capacity and power consumption ratio.
