摘　　要： 通过对翅片管蒸发器建立集中参数模型,研究了管排数对变频空调蒸发器换热性能的影响。研究结果表明,管排数增加,总换热量的增加并不显著,但管排数每增加一排平均每排管的换热量减少18%左右;风机功率越大,达到最大换热量的管排数也越多。 A lumped-parameter model of tube-fin evaporator was proposed.The influence of number of tube rows on the heat transfer performances of evaporator in inverter air-conditioner system was analyzed.The results show that the total heat transfer rate increases indistinctively as number of tube rows increases,while the average heat transfer rate of each tube row reduces about 18% for one row added.The number of tube rows increases as the power of fan increases when the total heat transfer rate reaches maximum.
