Abstract

Absorption heat pump system using R1234ze(E)/ionic fluid is developed for cooling and heating application in Proton-Exchange Membrane Fuel Cells (PEMFC) vehicles. Waste heat from the PEMFC is utilized as the heat source of the absorption heat pump system. A low global warming potential (GWP) refrigerant of (R1234ze(E)) and an ionic fluid of [hmim][Tf2N] are used as refrigerant and absorbent, respectively. Additionally, the heat pump system is assisted by a compressor placed between evaporator and absorber. Cooling and heating performance of the absorption heat pump is evaluated under various generator and absorber temperatures and concentrations. The results show that the coefficient of performance of refrigeration (COPc) is up to 0.566 and the COP of heat pump(COPH) is up to 1.517.
