| 摘 要： | 当室外气温较高时，风冷热泵系统冷凝器存在换热效果下降的问题，而蒸发式冷凝器可以改善此问题，蒸发式冷凝器因此逐步得到广泛重视。为研究采用蒸发式冷凝器制冷系统的能耗情况，通过正交实验的方法，对比研究了蒸发式冷凝器与风冷式冷凝器在相同工况下压缩机能耗情况，并对影响其性能的因素进行了分析。研究表明，各因素对压缩机耗功量的影响能力依次为：冷凝器进口空气温度、速度及冷凝器喷水量。压缩机耗功量随进口空气温度的升高、进风空气速度降低而增大，随喷水量增加存在先减小后保持不变的现象。

| Abstract: | The heat transfer efficiency of air-cooled heat pump system would decrease in high outdoor temperature. Evaporative condenser gradually get wide attention due to its contribution to solve the problem. In order to study the energy consumption of heat pump with evaporative condenser, it was made a comparative study about compressor power consumption of evaporative condenser and air cooling condenser under the same conditions by orthogonal experiment and analyzed factors of efficiency. The results show that the influence of factors on power consumption and energy efficiency of compressor are as follows:inlet air temperature of condenser water volume, air velocity. Compressor power consumption increases with the increase of inlet air temperature and the decrease of air velocity. The compressor energy consumption decreases at first and then is constant with the increase of water volume. |
