| 摘 要： | 为了优化热泵系统效率,主要采用编程计算,对以R32、R290以及R410A为工质的两级压缩热泵系统进行性能研究,对比了系统的蒸发温度、冷凝温度、中间温度和混合温度等对COPh的影响。研究发现不完全冷却系统COPh比完全冷却系统更高,在不同工况下存在不同的最佳中间温度,使得COPh有最大值,R290和R410A的混合温度变化对系统COPh影响较大。

| Abstract: | Since air source is a renewable energy source,air source heat pumps have been more and more widely used in building heating.How to reduce the energy consumption of heat pumps has become the theme of energy saving and emission reduction.In order to optimize the efficiency of the heat pump system,this paper mainly uses programming calculations to study the performance of a two-stage compression heat pump system using R32,R290 and R410A as working fluids.The evaporation temperature,condensation temperature,intermediate temperature and mixing temperature of the system are compared for COPh Impact.The study found that the COPh of the incomplete cooling system is higher than that of the complete cooling system.There are different optimal intermediate temperatures under different working conditions to make the COPh have the maximum value.The mixed temperature changes of R290 and R410A have a greater impact on the COPh of the system. |
