Described CO 2 trans-critical heat pump air-conditioning system is connected into the loop by compressor 1, cross valve 2, fluid reservoir 4, internal exchanger 5, and the left side one tunnel and the cross valve 2 of the right one tunnel by cross valve 2, first evaporator 3, cross valve 4, second evaporator 7 connect into the loop; Wherein internal exchanger 5 also and cross valve 4, valve 6 composition loops.
Described heat pump type air conditioning system adopts critical carbon dioxide as working medium, and corresponding critical piece and pipe-line system should satisfy the requirement of withstand voltage of 15MPa.
The water loop system and the refrigeration system of described solar thermal collector can be separate.
Described hot water storage tank 11 inner water-tank heat exchange coils 20 both can be used as the hot water storage tank that the domestic hot-water is provided, and can be used as the low level heat energy that heat is provided again.
The described low level heat energy that heat is provided (if simple soil source as low level heat energy, temperature is greatly between 5-20 ℃) adopts independent hot water storage tank loop or soil source and hot water storage tank series loop.
The invention has the beneficial effects as follows solar thermal collection system, heat transfer system of underground heat exchanger, CO 2 trans-critical heat pump air-conditioning system are closely cooperated, heat, freeze, heat to adapt to the spring, summer, autumn and winter Various Seasonal+hot water, different demands such as refrigeration+hot water, hot water, reach facility compact, complete function, the requirement of energy efficient.
The present invention at first adopts this green working medium of carbon dioxide, and next adopts solar thermal collection system, has utilized reproducible solar energy, has the advantage of energy-conserving and environment-protective.Adopt soil as low level heat energy once more, improved the coefficient of performance, and " urban heat land effect " of having avoided employing air heat transmission equipment to bring.
