Abstract: Aiming at the facts that lots of low temperature waste heat from some industries(such as oil, chemical, power and steeel works) is abundant but rarely used, a waste heat recovery analog experiment on a home-made high temperature heat pump set-up is conducted. According to the test data and results, the empirical expressions of all performance indexes are regressed under the condition of using R142b as refrigerant, heat source temperature at 35～45 °C, heating temperature at 60～85 °C, and compressor output at 2.3～3.7 kW. Also the impacts of parametric variations on performance indexes is analyzed. Furthermore, an engineering trial is performed by an industrial heat pump made overseas operating in oil field. The investiga-tions indicate massive energy can be saved if heat pump is ap-plied to recover the low temperature waste heat from oil pro-duction process. The operating cost of heat pump system is nearly the same as that of heater system, which restricts the popularization of heat pump.
