摘要
本文通过实验与仿真手段研究极端气候条件下家用空调的性能。文中首先采用RefProp软件建立了家用空调的理想性能模型,利用焓差室对家用空调在极端气候条件下的性能进行测试,再通过实验数据来修正模型。在修正后的空调模型中,空调的制冷/制热量、COP和电功率的平均误差都小于10%。通过实验数据与仿真计算可知,在夏季工况下,室外温度的上升将严重降低空调的能效,当室外温度为50℃时,产生相同冷量所需要的电量将是室外温度30℃时的210%左右;在冬季工况下,室外温度的下降将严重降低空调的能效,当室外温度为-5℃时,产生相同热量所需要的电量将是室外温度10℃时的170%左右。
The performance of household air conditioners in the extreme climate condition was reached in this paper by experimental and simulation method. The performance model of household air conditioners in the ideal conditions was built by RefProp software firstly. The performance of household air conditioners in the extreme climate condition was tested through an enthalpy difference lab. Then the performance model was modified by the experimental data. By the modified model the average deviations of heating/cooling capacity, COP and electric power are all less than 10%. The experimental data and simulation results shown that in summer, the rise of outdoor temperature will obviously reduce the energy efficiency of the air conditioner. When the outdoor temperature is 50 ℃, the electric power will be about 210% of the electric power if the outdoor temperature is 30 ℃. And in winter, the fall of outdoor temperature will also obviously reduce the energy efficiency of the air conditioner, when the outdoor temperature is -5 ℃, the electric power will be about 150% of the electric power if the outdoor temperature is 10 ℃.
