摘要
燃气机热泵是一种高效节能的制热、制冷系统,回收燃气发动机的余热对于提高燃气机热泵的一次能源利用率有着十分重要的意义。对燃气机余热的组成,余热利用的限制条件,燃气机热泵在制热工况下的余热直接回收方式及在制冷工况下的采用压缩式与吸收式制冷循环相结合的余热联合回收方式进行了分析。
Gas engine-driven heat pump is a high-efficient energy-saving heating and refrigeration system. It is of great importance to recover the residual heat from gas engine for improving the primary energy utilization rate of gas engine-driven heat pump. The composition of residual heat, limit conditions of residual heat utilization, direct recovery mode of residual heat of gas engine-driven heat pump under heating work condition and combined recovery mode of residual heat of gas engine-driven heat pump using compression and absorption refrigeration cycles under refrigeration work condition are analyzed.
