| 采用平衡环境型房间量热计测试了亲水性不同的三组铜翅片蒸发器在不同含湿量下空调制冷性能,测试结果显示,在低湿时,除湿量较小,凝结水排除能力足够,亲水性改善空调制冷性能作用不大,在高湿时,除湿量较大,需要较强的凝结水排出能力,亲水性改善空调制冷性能作用明显。 |

| Abstract: |
| Performance tests were conducted on three finned tube evaporators, which included one untreated copper fin evaporator, two hydrophilic treated copper fin evaporators. Each evaporator was tested with it being installed in the indoor unit of a cabinet- type air conditioner, which was used as the platform of the performance tests. Tests were conducted using the calorimeter method under the different humidity air conditions. The results showed that the evaporator surface wettability has notable effect on the air conditioner performance at high humidity air conditions because of strong ability to discharging great dew water, not at low humidity air conditions because of less water condensate. |
