SOLAR-ASSISTED HEAT-PUMP AND ENERGY-STORAGE FOR RESIDENTIAL HEATING

In order to investigate the performance of a solar-assisted heat pump system with energy storage for residential heating in the Black Sea re gion of Turkey, an experimental setup was constructed. This experiment al apparatus consisted of flat plate solar collectors with total area of 30 m2, a laboratory building with 75 m2 floor area for heating purp ose, a latent heat thermal energy storage tank filled by 1500 kg encap sulated phase change material (PCM), a heat pump with double evaporato rs (air-sourced and water-sourced) and one condenser, a water circulat ing pump, and measuring equipments. The experimental results were obta ined December-May during the heating season of 1992 for the solar-assi sted heat pump system used. The experimentally obtained results were u sed to calculate the collector efficiency, coefficient of performance of heat pump (COP), system COP, storage efficiency, and total energy c onsumption of the system during the heating season. The mean value of the collector efficiency, heat pump COP, system COP, and storage effic iency were found 70%, 4.5%, 4.0%, and 60%, respectively.
