Design and Economic Analysis of Photovoltaic-Double Resource Heat Pump.

Abstract: In order to improve the photoelectric efficiency and solar energy utilization of PV module, a set of photovoltaicdouble resource heat pump (PV-DHP) is designed in this paper. Through calculation of system performance, the result shows that the efficiency of PV-DHP system can be up to 4.86 and photoelectric efficiency increases highly. According to economic compare, it is known that the operation cost of PV-DHP is 61.6% of air source heat pump, 16.6% of oil-fired boiler and 19.5% of electric heater. [Copyright &y& Elsevier]
