Energy Analysis of Gas Engine Driven Heat Pump

In the face of power shortages, an analytical investigation on the displacement of electrically driven heat pump by gas engine driven heat pump is undertaken. The energy conversion process comparison based on existing data between electrically driven vapor compression heat pump (EVCHP) and gas engine driven vapor compression heat pump (GVCHP) indicates that GVCHP can improve the energy efficiency and exergy efficiency with the application of waste engine heat recovery for heat supply and the majority of loss in GVCHP occurs in the engine.
