摘要
定期对分体式房间空调器的换热器进行清洗,不仅可以有效避免其长期运行累积的病菌、灰尘等对室内空气的污染,而且有助于提高空调器的节能效果。因此,本文采用空气焓差法对换热器清洗前后的分体式房间空调器性能进行测试,通过制冷能力和消耗功率这两个参数计算得到换热器清洗前后空调器的能效比。测试结果表明:进行换热器的清洗后,空调器的制冷能力测量均值增加4.37%,消耗功率增加1.21%,而能效比则由2.07增加到2.14,提高幅度为3.12%。
Cleaning heat exchangers of split-type air conditioning regularly has two key effects, not only can it avoid the long run cumulative bacteria, dust and other pollution of indoor air effectively, but also it can improve the performance of the air-conditioning system hence energy can be saved. After the energy performance measurement of split-type air conditioning by air enthalpy difference method before and after the cleaning of heat exchangers, the refrigerating capacity and power consumption was gotten, and the energy efficiency ratio was calculated. The result indicates that after the cleaning of split-type air conditioning heat exchangers, mean refrigerating capacity increases 4.37% and power consumption increased by 1.21%, and the energy efficiency ratio was increased from 2.07 to 2.14, increased by 3.12%.
