摘要

利用EVAP-COND软件

模拟对比了在室内换热器中分别采用R22与R410A制冷剂时蒸发器的性能随支路数的变化

结果表明:室内换热器作为蒸发器时

R410A的换热量比R22的要大

换热量之差随支路的增多先减后增

最大差别幅度为19.41%; 作为蒸发器时

R410A第1排管的传热温差和传热系数都比R22的要大

而第2排管基本相同

因此R410A和R22蒸发器换热量的差别主要是由第1排管引起的; 随支路数的增多

传热温差对蒸发器换热量差别的影响逐渐减弱

而传热系数的影响逐渐增强

制约R410A和R22蒸发器换热量差别的主导因素从传热温差逐渐转变为传热系数.

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 version simulation package of NIST. The variation in the evaporator capacity with the circuit number is also analyzed. The results show that the capacity of the evaporator with R410A is greater than that with R22. Moreover

the difference in the capacity of the evaporator with R410A and R22 drops first

and then it rises with the circuit number and the maximum difference is 19.41%. Both the air-and-refrigerant temperature difference and the overall heat transfer coefficient of the evaporator with R410A are greater than those with R22 in the first row

but they are almost equal in the second row. Thus the tube capacity sum in the first row contributes to the difference in the evaporator capacity. In addition

the effect of the air-and-refrigerant temperature difference on the difference in the capacity of the evaporator with R22 and R410A may decrease with the increase of the circuit number while the effect of the overall heat transfer coefficient may increase with the circuit number.
