摘要(Abstract)：

为了了解高温热泵系统中,压缩机频率对系统循环参数影响规律,本文在R410A高温热泵试验台上,在较大频率范围内(40~120Hz)对各循环参数如蒸发温度、冷凝温度、排气温度、压比、过冷度、过热度等与频率之间的关系进行了试验研究。试验结果表明,冷凝温度、排气温度、压比、过热度随频率的升高而增大,蒸发温度,过冷度随频率的升高而减小。
study the affection of the compressor frequency on the cycle parameters in medium-high temperature heat pump system.On R410a medium-high temperature heat pump bench,experimetlly study the relationship between the evaporating temperature,condensing temperature,discharge temperature,comprssion ratio,degree of superheat,degree of subcooling and frequency,with the frequencies changing from 40Hz to 120Hz.The result showed that the condensing temperature,discharge temperature,compression ratio,degree of super heat was direct ration with frequency,but evporating temperature,degree of subcooling was reverse with it.
