Abstract:For the facts that lots of low-temperature waste heat from industries (such as oil plants, chemical plants, power plants or steel plants) is abundant but rarely used, a series of analogue tests are conducted by using indoor high-temperature heat pump set-up. According to the tested 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  , heating temperature at 60  85  , and compressor output at 2.3  3.7kw. Also the impact of parametric variations on performance indexes is analyzed. Furthermore, an engineering trial is performed by an industrial heat pump abroad operating in oil field. The investigations indicate that massive energy can be saved if heat pump is applied to recover the low temperature waste heat discharged from oil production process. But the operating cost of heat pump system is nearly the same as that of heater system in practical operation. This restricts the popularization of heat pump in oil field. ? 2010 IEEE.
