摘要(Abstract):

建立了超临界二氧化碳汽车空调器循环计算模型 ,结合美国Illinois大学制冷空调中心 (ACRC)二氧化碳汽车空调样机实验结果 ,对两种压缩机转速和两种气体冷却器空气进口温度的不同组合条件下的工况 ,进行了循环计算 ,并对计算结果作了分析。计算结果表明 ,压缩机转速越高 ,或者气体冷却器空气进口温度越高 ,二氧化碳汽车空调的工况越恶劣 ,COP值越低
A model of a carbon dioxide automobile air conditioner is established, combined with the experimental results of air conditioning and refrigerating center (ACRC) of Illinois University in the United States. The performance under different working conditions with three compressor rotating speeds and four inlet air temperatures of gas cooler is calculated and analyzed. The results show that, higher the compressor rotating speed or the inlet air temperature of gas cooler is, worse the working condition and smaller the value of coefficient of performance.
