The solar energy combined radiant wall heating system of the present utility model, combined with Fig. 1, Fig. 2a and Fig. 2b, combines the solar energy heating system with the wall radiant heating mode, effectively utilizes clean energy for heating and reduces building energy consumption. Including the radiant heating pipe network structure 9, one end of the radiant heating pipe network structure 9 is connected with the auxiliary heat source 7, the other end of the radiant heating pipe network structure 9 is connected with the hot water storage tank 5 through pipes, and the radiant heating pipe network structure 9 is connected with the heat storage. The pipes between the water tanks 5 are also provided with a heat supply pump 8 and a three-way valve 6 in turn. The other port of the three-way valve 6 is connected to the auxiliary heat source 7 through the pipeline, and the hot water storage tank 5 is also connected to the plate heat exchanger through the pipeline. 3 connection, the plate heat exchanger 3 is also connected with the solar collector 1 through pipes.

A heat collection pump A2 is also arranged between the water inlet end of the plate heat exchanger 3 and the solar heat collector 1 .

A heat collection pump B4 is also provided on the pipeline between the hot water storage tank 5 and the water outlet end of the plate heat exchanger 3 . As shown in FIG. 1 , under the action of the heat collection pump A2 and the heat collection pump B4 , the water body in the solar heat collector 1 is heated by solar radiation and then exchanges heat through the plate heat exchanger 3 and stores it in the hot water storage tank 5 . The hot water in the hot water storage tank 5 finally flows to the wall radiant heating pipe network structure 9 through the auxiliary heat source 7 to heat the room.

The radiant heating pipe network structure 9 is placed in a wall with insufficient light and large heat loss. The wall body is composed of a fine stone concrete layer 11 , a radiant heating pipe layer 12 , a thermal insulation layer 13 , a reinforced concrete structure layer 14 , and an outer wall decorative layer 15 in order from the inner wall decoration layer 10 .

The radiant heating pipe layer 1 is a pipe regularly curved between the fine stone concrete layer 11 and the thermal insulation layer 13 . On the basis of combining with the solar heating system, it can effectively reduce the indoor heat loss while heating the room.

The auxiliary heat source 7 may be one of air source heat pump, electric heating and the like.

The solar energy is converted into heat energy by the solar collector 1, and the heat is exchanged to the hot water storage tank 5 through the plate heat exchanger 3 for storage. When the temperature of the water body in the hot water storage tank 5 meets the heating requirements, the hot water storage tank 5 directly provides heat for the radiant heating terminal; Finally, it flows to the radiant heating pipe network structure 9 to heat the room; when the temperature of the water body in the hot water storage tank 5 is lower than the heating return water, the heating return water directly enters the auxiliary heat source 7 for reheating, and the hot water storage tank 5 does not participate in the heating process.

The hot water in the hot water storage tank reaches the radiant heating pipe network on the side wall of the room under the action of the heating circulation pump, and heats the indoor air through convection heat exchange and radiation heat exchange. Compared with traditional floor radiant heating, the heating pipe network is laid in the side walls, the heating speed is fast, and the heat exchange is sufficient, which solves the shortcoming of fast heat loss caused by less solar radiation and low temperature on the north wall. Clean energy, reduce energy consumption, greatly reduce environmental pollution and achieve the effect of energy saving and emission reduction.
