Résumé

A simulation study on solar hybrid heat pump system using carbon dioxide for residential applications was carried out for varying operating conditions. The system consists of a solar system (concentric evacuated tube solar collector and heat storage tank) and a CO2 heat pump system (double-pipe heat exchanger, fin-tube heat exchanger, electric expansion valve,and compressor). As a result, the solar collector efficiency and solar collector heat were decreased by 7.6% and 2.7 kWh, respectively, when the heat pump operating temperature rose by 2°C. As the outdoor temperature rose by 2°C, the heat pump heating COP increased by about 6.5% and heating load decreased by about 7.6%, on average. Also, the heating load increased by 14.3% with a rise of indoor setting temperature of 2oC. The solar hybrid CO2 heat pump system in this study had maximum solar fraction of 24.5%.
