摘要(Abstract):

模拟5个不同的环境工况,对外盘管空气源热泵热水器进行了一系列的试验研究。分析了环境温度对水加热速率的影响,以及环境温度和水温变化对系统制热量、压缩机压比、性能系数(COP)、排气温度、排气压力等参数的影响,为提高系统性能的进一步研究提供了理论依据。
Through simulating five different environmental conditions,a serials of experimental studies were carried out on external coil air source heat pump water heater.The influence of ambient temperature on water heating rate,and the influence of ambient temperature and water temperature on heat output,compression ratio of compressor,coefficient of performance(COP),exhaust temperature,exhaust pressure,etc,were analyzed in this paper,which will provide theoretical basis for further study on improving the sytem's performance.
