Experimental study on cooling performance and energy saving of gas engine-driven heat pump system with evaporative condenser

“…The results showed that the exergetic efficiency values were in the range of 77.68-79.21% for the heat pump unit, 39.26-43.24% for the gas engine driven heat pump unit, 81.29-81.56% for the during chamber and 48.24-51.28% for the overall drying system. Chen et al [19] presented a new system of air source energy independence driven by internal-combustion engine, and investigated a thermal model of a GEHP system working as water heater, furthermore, the heating capacity, coefficient of performance and primary energy ratio of the GEHP system were also studied by thermodynamic simulation and experiment. Kamal et al [20] investigated the field performance of gas engine driven heat pumps used in a commercial buildings.…”

Natural gas engine driven heat pump system – a case study of an office building

“…The gas engine-driven heat pump (GEHP) is a new energy-efficient heating and air conditioning equipment that utilizes natural gas as the fuel in the gas engine that drives compressor coupled to it [4][5][6][7]. The GEHP system is predominantly composed of vapor compression heat pump system that is driven by a gas fueled internal combustion engine, the cold and heat source system, the data acquisition and controlling system.…”

“…The GEHP system is predominantly composed of vapor compression heat pump system that is driven by a gas fueled internal combustion engine, the cold and heat source system, the data acquisition and controlling system. Among the heat pump systems, recently GEHPs have been given more emphasis as a preferable choice in the heating and air-conditioning system [7]. This is due to their notable advantages such as capability to recover about 80% waste heat from internal combustion engine [8], higher primary energy ratio [5], elimination of losses caused by electricity production and transportation [9] and easy modulation of the compressor speed (by adjusting the gas supply) to meet the different load demands [10,11].…”

Experiments and thermal modeling on hybrid energy supply system of gas engine heat pumps and organic Rankine cycle

“…The dynamic modeling of GEHP system during startup in cooling mode and variation of evaporator and condenser temperature, shaft power consumed by compressor, engine fuel consumption and primary energy ratio of system were also researched [13]. A new system of air source energy independence driven by internal-combustion engine [14,15] has been presented, and a thermal model of a GEHP system working as water heater was investigated, furthermore, the heating capacity, coefficient of performance and primary energy ratio of the GEHP system were also studied by thermal simulation and experiment.…”
