摘要
对热泵空调系统制热工况下的性能进行了研究,基于热泵空调系统制热工况与制冷工况的差异性,提出制热时以车内冷凝器温度作为目标温度的控制策略。基于Simcenter Amesim搭建了热泵空调系统制热循环模型,利用Simulink建立了控制策略仿真模型,并联合仿真对比研究了以车内冷凝器温度和车内传感器温度分别作为目标温度时的系统性能。与控制车内传感器温度相比,以车内冷凝器温度作为目标温度时,前600 s系统COP高出5%以上,车内温度调节时间较长,舒适性较差。
The paper investigates the heating performance of heating condition for heat pump air conditioning system and proposes a new control strategy which treat the inner condenser inlet temperature as control objective in heating condition based on the differ-ence between heating condition and cooling condition of heat pump air conditioning system.A simulation model about heating mode of heat pump air conditioning system based on Simcenter Amesim is built and a control strategy model is built by Simulink.By joint simulation,the system performance is studied despite of the control objective is inner condenser inlet temperature or temperature sensor’s value in a car.Compared with temperature sensor’s value,the system COP of heating mode is 5 percent more and temperature regulation time is longer when inner condenser inlet temperature is selected as control objective during first 600 s.
