浅析热泵

通过回顾热泵的发展及应用，论述了热泵的能量流动及转化过程，分析了热泵供热制冷系统的技术性和热泵供热的经济性，对热泵供絷系统和传统供热系统进行了比较，指出热泵供热在实际应用中具有优缺点，即：热泵供热技术对大气及环境无污染，能源消耗低，年运行费用也低，但热泵的初投资费用较高。

Simple analysis on heat pump

Through looking back on the development and applica tion of heat pump, the writer discusses the energy flowing and converting process of heat pump, ana lyses the technicality of heating?refrigerating system and the economical quali t y of heating system. In addition, the writer compares the heat system of heat pu mp with the traditional heat system, pointing out the advantages and disadvantag es of the heat pump in actual application. That is heat pump technique can't pol lute the air and environment and consumes fewer energy, costs lower expenditure per year, but it invests more at first.
