PERFORMANCE OF SOLAR ASSISTED HEAT PUMP USING PV EVAPORATOR UNDER DIFFERENT COMPRESSOR FREQUENCY
A novel photovoltaic solar assisted heat pump (PV-SAHP) system was constructed with the PV cells laminated onto the evaporator-collector plate. So a portion of the solar energy received was converted to electricity and the rest was converted as heat. The heat energy was then absorbed by the refrigerant and carried over to the condenser. Photovoltaic efficiency was increased in this way due to the lowered PV cell operating temperature as a result of the refrigerant evaporation process. The COP of the heat pump was also substantially improved because of the solar energy absorption. Performance tests under frequency 40Hz, 60Hz of compressor were conducted on the experimental rig. The dynamic performance of this PV-SAHP system was analyzed and the influencing factors were identified. The results indicate that this PV-SAHP system has a superior performance than the conventional heat pump system and at the same time, the photovoltaic efficiency is also higher.
