PERFORMANCE OF A SOLAR INTEGRATED HEAT PUMP AIR-CONDITIONER, WATER HEATER AND DRYER

In this study, a solar assisted heat-pump system for air-conditioning, water heating and drying was designed, constructed and performance evaluated. The three applications can be served simultaneously or independently. The presence of an innovative two-phase unglazed solar evaporator-collector, wher...
