The Analysis of the Performance of Heating and the Economical Efficiency of the Solar Energy and Gas Heat Pump.

The solar and gas heat pump heating system is a system that combines the gas heat pump and the solar heat pump driven by electricity. On the one hand, the system makes full use of the solar, and it is a real High-efficiency, energy-saving system. On the other hand, the system use natural gas as an energy source which can relieve the energy crisis, reduce environmental pollution and relieve the pressure of the grid. During the operation of the system, it will save operating costs due to the cheaper price of gas compared with electricity. Therefore, the research of the solar and gas heat pump has a great sense of energy-saving and economical. [ABSTRACT FROM AUTHOR]
