[0027] In the embodiment of the utility model, the solar collector 2 is a PV / T collector, and the components thereof are in sequence: tempered glass, EVA, photovoltaic cell, TPT, flat heat pipe, rectangular heat collection water tank, water flow channel and thermal insulation layer. In the initial assembly, taking the north-south orientation of a building as an example, the solar collector 2 is installed on the south direction (high radiation surface) of the building, and the capillary tube 3 is arranged on the north direction (low temperature surface). The solar collector 2 on the south direction of the building efficiently absorbs solar radiation, and at the same time, the circulating pumps 51 of the two circulating output pipes 5 are started to Figure 1 For example, the two circulating pumps 51 are a south circulating pump 51 and a north circulating pump 51. When the south circulating pump 51 works, water in the energy storage water tank 1 is transported to the solar collector 2 through the corresponding circulating output pipe 5. The flat heat pipe laid on the back of the photovoltaic cell absorbs the waste heat of the back of the photovoltaic cell, which can strengthen the heat transfer and transfer heat to the circulating water entering the rectangular heat collection water tank. The water after being heated is returned to the energy storage water tank 1 through the corresponding circulating input pipe 4. At the same time, under the action of the north circulating pump 51, the water after being heated in the energy storage water tank 1 is transported to the capillary tube 3 through the corresponding circulating output pipe 5. The capillary tube 3 exchanges heat with the surrounding air to achieve the purpose of heating the room. At the same time, the water in the capillary tube 3 enters the energy storage water tank 1 through the corresponding circulating input pipe 4 and is heated again by the solar collector 2, which improves the temperature of the north direction of the room and ensures the uniformity of the indoor temperature distribution.
