| 摘 要： | 试验对比研究在翅片管换热器底部设置1根U形管过冷、2根并联U形管过冷、2根串联U形管过冷的过冷效果，测试数据表明用2根U形管串联进行过冷的效果最好。当把2根铜管串联用于过冷时，对R22制冷剂在B工况测试条件下，与没有过冷相比，过冷度增加了1．1℃，能效比高出0．33W／W，提高了8．25％；对R410A制冷剂在B工况测试条件下，与没有过冷相比，过冷度增加了2．0℃，能效比高出0．10W／W，提高了2．69％。

| Abstract: | Three kinds of subcooled U tube design of a fin- tube heat exchanger on the performance of the air conditioner were investigated experimentally. The 1 U tube, 2 parallel U tubes and 2 series U tubes at the bottom of a fin - tube heat exchanger were designed and tested. It is showed that the design of 2 series U tubes design will get the best performance of the air conditioner. Comparing to the no subcooled U tube design, the 2 series U tubes subcooled design gets the results of subeooling increasing 1.1 ℃, energy efficiency ratio increasing 0.33W/W, that is 8.25 percent for R22 refrigerant under B test of ARI 210- 240; and the subcooling increasing 2.0℃, energy efficiency ratio increasing 0.10W/W, that is 2.69 percent for R410A refrigerant under B test of ARI 210- 240. |
