It is the most popular oneR22Refrigerant comparison,R410AThere are many advantages in performance and good heat transfer property. Its main performance advantages are reflected in the following aspects:

1) andR22Comparison,R410AThe system has a distinct advantage: the heat transfer of the evaporator is high35%The heat transfer of condenser is high5%But,R407CandR134aThe heat transfer coefficient is lower than that of the heat transfer coefficientR22

2The cycle work pressure ratioHCFC-22About57%Unit volume refrigerating capacity ratioHCFC-22About43%Refrigeration coefficient ratioHCFC-22About small7.7%And the other parameters andHCFC-22Basically close.

3Under the same mass flow rate,R410AThe pressure drop is small so that it can be usedR22Or other refrigerants, smaller pipes and valves, which can reduce the cost of materials

4) andR410AThe matching system is better than that of the matched systemR22The system can be used with smaller volume condensers and evaporators, with lower cost and highest accessibility30%Refrigerant charge reduction. The reduction of refrigerant charge can not only reduce the cost, but also improve the reliability of the whole system.

5Due to the lower loss of compressor in compression process, the evaporator and condenser have stronger heat transfer, and the pressure drop in the whole system is smaller, so the system has the same cooling capacity and the same condensing temperature,R410AEnergy efficiency ratio of the systemCOPThan)R22Higher system6%. The high efficiency heat transfer and smaller pressure drop make the condensing temperature lower and the evaporation temperature higher under the same operation condition, which makes the compressor obtain a better operating range under the condition of less power consumption and higher efficiency.

(6) because R410A is a mixed refrigerant, please shake it several times before charging.
