摘要
搭建了电动汽车热泵空调系统仿真模型和性能仿真分析平台,分析了热泵空调系统在不同模式下的性能,并采用试验结果对仿真模型进行验证。结果表明:试验得到压缩机功率、换热量、系统COP值与对应的仿真值之间的最大误差为4%~10.09%。在制冷模式和制热模式下,随着压缩机转速的增大,压缩机功率逐渐增大,换热量逐渐增大,系统COP逐渐减小。此外,研究了冷凝器、蒸发器进风风量、进风温度、进风方式等因素对制冷模式和制热模式下系统性能的影响,结果表明,制冷时采用大风量有利于提高制冷量,进风温度的影响取决于工况特征,而采用部分进风方式更有利于系统制热节能。
A heat pump air conditioning system performance simulation platform for electric vehicle is designed and built, which can be used to analyze the system performance in different working modes. The experimental results are used to verify the simulation model accuracy. The results show that the maximum error between experiment and simulation data of compressor power, heat exchange rate and system Coefficient of Performance(COP) is 4%~10.09% in different working modes. The compressor power gradually increases, the heat exchange rate gradually increases and the system COP gradually decreases with the increase of compressor speed in the cooling mode and heating mode. The influence of inlet air flow rate, inlet air temperature, inlet air mode and other factors of condenser and evaporator on the system performance in the cooling or heating mode are also researched in the paper. The results indicate that high air flow rate will improve the cooling capacity, and the effect of inlet air temperature is dependent on working condition, while the partial inlet air mode can save energy in heating mode.
