The temperature of the exhaust heat during the process of yielding the oil and the remaining heat in the electricity plant is low , and they are usually been regarded as wasting heat and thrown away , but the temperature of these heat is higher than the temperature of the environment . if we can design the corresponding heat pump device and reclaim this part of heat , the economic benefit is very considerable 石油生产中的废热和电厂余热温度低，通常被当作废热扔掉，但这部分热量的温度比环境温度高许多，设计相应的热泵装置，回收这部分热量，经济效益可观，本文以石油生产和电厂余热回收利用为出发点，研究热泵技术在油田及电厂的应用。
