Research on the triple system based on solar and air source heat pump.

We submit a triple system based on solar and air source heat pump and establish steady-state operation mathematical model Based on the 60 m2 room in Wuhan city. We obtain the different system parameters under the cooling model, heating model, hot water supply model, cooling and hot water supply model, heating and hot water supply model, heating by hot water mode. It shows the high-performance, remarkable energy-saving effect, even in extreme weather, it still can meet the requirements.
