摘要

本文通过实验研究了电动汽车三换热器热泵空调系统在冬季运行时的采暖性能，研究分析了压缩机在不同转速(2 000~5 000 r/min)下，室内外环境温度和相对湿度对系统内压缩机排气特性、汽车HVAC总成出风温度和COP等系统性能参数的影响。结果表明：较高的压缩机转速使出风温度和制热量明显上升，但系统COP有所降低；当保持压缩机转速不变时，环境温度每升高5 ℃时，制热量升高9%~22%，出风温度上升6~9 ℃，COP上升7%~11%；室外相对湿度由40%增至80%时，制热量增加了15%~20%，出风温度上升2~3 ℃，COP上升6%~9%。

Abstract

The heating performance of a three-heat exchanger heat pump air-conditioning system of an electric vehicle in winter is investigated experimentally. The effects of indoor

outdoor ambient temperatures and relative humidity on the outlet temperature of the heating ventilation and air conditioning (HVAC) module

coefficient of performance (COP) and other performance parameters are investigated at different compressor speeds. The results show that higher compressor speeds can improve the outlet air temperature and heating capacity of the HVAC module

but the COP of the system decreases. When the compressor speed is maintained constant

for every 5 ℃ increase in the ambient temperature

the heating capacity increases by 9%–22%

the outlet temperature increases by 6–9 ℃

and COP increases by 7%–11%. When the outdoor relative humidity increases from 40% to 80%

the heating capacity increases by 15%–20%

outlet temperature increases by 2–3 ℃

and the COP increases by 6%–9%.
