摘　　要：R32因其良好的热物性和环保性能,作为制冷空调系统的一种过渡性替代制冷剂受到越来越多的关注。本文利用实验研究的方法,研究了一种R32家用空调系统名义制冷/制热工况下不同风机转速、压缩机频率和制冷剂充注量对系统制冷量/制热量、制冷/制热功率以及COP/EER。实验结果表明,室内机和室外机风速的改变对空调效率的影响不完全相同,压缩机频率在制热工况下对空调效率的影响更大,更改制冷剂充注量对于COP/EER的影响曲线呈现不同趋势。R32 is receiving increasing attention as a transitional alternative refrigerant for refrigeration and air conditioning systems due to its good thermo-physical and environmental performance.In this paper,the cooling/heat production,total power and COP/EER of an R32 domestic air-conditioning system under different fan speeds,compressor frequencies and refrigerant charges at nominal operating conditions are investigated using an experimental study.The experimental results show that the effect of changing the air speed of the indoor and outdoor units on the efficiency of the air conditioner is not exactly the same,the compressor frequency has a greater effect on the efficiency of the air conditioner under heating conditions,and the effect of changing the refrigerant charge on the COP/EER curve shows different trends.
