Affect the efficiency of high temperature heat pump has two factors, one is the heat pump circulation internal loss size popularly said compressor mechanical loss is two high temperature end and low temperature end heat exchanger irreversible heat loss.
主要还是跟载热介质有关，?#36816;?#20026;载热介质的热泵其热泵效率一般要大于相同温度范围工作的空气热泵， 大型热泵?#20302;?#30001;于压缩机效率较高和流程损失相对较少其热泵效率一般要大于小型热泵，随着高低位热源的温差加大，热泵系数总是降低的。而对较大型的?#20302;?#21487;采用多级压缩、回热等各种措施减少不可逆损失，从而提高热泵效率。随着大型全封闭和半封闭式压缩机技术的成熟及高温热泵工质研究的进展，开发和生产供热温度为100 ℃～150 ℃的地源、水源或空气源高温热泵装置并不困难，其关键是如何降低热泵装置成本和提高它的效率。
It is with the heat carrying medium, air heat pump with water as the heat pump heat carrying medium of the heat pump efficiency higher than the same working temperature range, large heat pump system due to high efficiency of the compressor and flow loss is relatively less than the pump efficiency of small heat pump with high temperature, low heat source heat pump coefficient increase, always reduced. For large systems, multi-stage compression, heat recovery and other measures can be used to reduce irreversible losses, thus improving the efficiency of heat pump. With the development of large-scale closed and semi closed compressor technology and high temperature heat pump research, development and production of heating temperature is 100 DEG C to ground source, water or air source heat pump device high temperature 150 DEG C is not difficult, the key is how to reduce the cost and improve the efficiency of heat pump it.
