Embodiment Construction

[0009] The implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0010] like figure 1 As shown, the present invention includes an active solar collector 101, a heat exchanger 102, a heat storage tank 103, a CO 2 An air source heat pump system 200 and a heating terminal system 300 .

[0011] The active solar heat collector 101 completes heat exchange with the water in the heat storage tank 103 through the heat exchanger 102, and the water in the heat storage tank is sent to the terminal heating system 300 through the circulation equipment.

[0012] CO 2 The air source heat pump system 200 is composed of a gas cooler 201 and a regenerator 202 , a throttle valve 203 , an evaporator 204 , a gas-liquid separator 205 and a compressor 206 . The CO 2 The air source heat pump system is connected to the water storage tank. When the solar radiation is weak, the water temperature in the water tank does not reach the pr...

Abstract

The invention discloses a heating system combining active solar energy and a CO2 air source heat pump. The heating system comprises an active solar energy collector 101, a heat exchanger 102, a heat storage water tank 103, a CO2 air source heat pump system 200, a heating tail end system 300 and a circulating system 400. The active solar energy collector 101 and the CO2 air source heat pump system 200 are two independent heating systems and supply heat to the heat storage water tank 103, and water in the heat storage water tank 103 is conveyed to the heating tail end system 300 through a circulating device. Renewable solar energy and energy-saving devices are utilized comprehensively for heating, renewable energy sources are utilized as efficient as possible, and the heating system combining the active solar energy and the CO2 air source heat pump is low in cost, high in system efficiency and remarkable in energy-saving and emission-reducing effect.
