| 摘 要： | 利用软件EVAP-COND,模拟对比了在室内换热器中分别采用R22与R410A制冷剂时冷凝器的性能随支路数的变化,结果表明:室内换热器作为冷凝器时,R410A的换热量比R22的要大,换热量的差别是由两排管共同造成的,两排管中R410A的换热量都比R22的要大;随支路数的增多,第一排管对冷凝器换热量差值的影响越来越显著,而第二排管的影响逐渐减弱;第一排管换热量的差别主要受传热系数的影响,而第二排管受传热温差和传热系数的综合影响。因此,支路增多时制约R410A和R22冷凝器换热量差别的因素,从传热温差和传热系数共同作用逐渐转变为传热系数起主导作用。

| Abstract: | The performance of the indoor coil in a split-type air-source heat pump with R22 and R410A is investigated numerically and compared by EVAP-COND 2.1.The indoor coil serves as an evaporator in a cooling cycle and as a condenser in a heating cycle.The variation in the condenser capacity with the circuit number is also analyzed.The results show that the condenser capacity with R410A as a refrigerant is greater than that with R22.The sums of the tube capacity in both the first and second rows with R410A are hig... |
