DETAILED DESCRIPTION
[0012] The specific embodiment of the present application is further described below.
[0013] The high-altitude solar heat collecting and storing integrated heating floor of the present application, as shown in Figure 1, comprises a floor base layer 11, a floor surface layer 6 and a solar heat collector 1 installed outside a building, further comprises a heat insulation layer 10 arranged on the floor base layer, a floor coil layer 9 arranged above the heat insulation layer, a phase change heat storage layer 8 arranged above the floor coil layer, and the floor surface layer 6 arranged above the phase change heat storage layer 8; the solar heat collector 1 comprises a heat collector coil, and the heat collector coil and the coil of the floor coil layer are connected through a water supply pipeline 2 and a return water pipeline 3 to form a circulating pipeline.
[0014] During the day, the solar heat collector 1 arranged outside collects solar energy and converts it into heat to heat the liquid heat conducting medium in the heat collector coil, the liquid heat conducting medium is generally water, and the water in the heat collector coil is transported in the circulating pipeline formed by the heat collector coil, the floor coil, the water supply pipeline 2 and the return water pipeline 3 passing through the outer wall 5, so that hot water continuously enters the floor coil layer through the water supply pipeline; the heat insulation layer below the floor coil layer is used to prevent heat loss to the floor below, and the heat insulation layer 10 generally uses polyurethane or rock wool; the phase change heat storage layer 8 is above the floor coil layer, which is easy to obtain heat in the coil layer below and also transfers heat to the floor surface layer above. The water in the floor coil layer returns to the solar heat collector for continuous heating after heat dissipation, realizing the transfer of heat in the water circulation process. The water in the floor coil layer radiates heat to the floor, and at the same time, part of the heat is absorbed by the phase change heat storage layer, which generally uses paraffin. The phase change heat storage layer can store heat by phase change of its own substance, from pure solid state to flowing state. When the water in the floor coil layer 9 cannot provide heat, the phase change heat storage layer will gradually recover to the solid form and release heat after the surrounding temperature decreases, slowly releasing the heat stored during the day at night, transferring heat to the room through convection and radiation in the phase change heat storage layer, thereby improving the indoor environment temperature.
[0015] As shown in Fig. 1, a regulating valve 4 can be arranged on the water supply pipeline 2 or the water return pipeline 3 in the water circulation pipeline, and the regulating valve can realize the regulation and closing of the flow of the liquid heat conducting medium in the circulation pipeline.
[0016] A leveling structure layer 7 is usually arranged above the floor coil layer, and the leveling structure layer 7 is provided with cavities for accommodating the fixed phase change heat storage layer 8, so that the phase change heat storage layer is inlaid in the cavities enclosed by the rigid support structure in the leveling structure layer 7, and deformation or penetration of the phase change heat storage layer is avoided. The leveling structure layer 7 is usually a cement or reinforced cement structure.
[0017] After the sun sets or the solar collector cannot output heat, the circulation pipeline can be cut off by the regulating valve, so that the water no longer circulates, thereby avoiding the cold water outside the room such as the collector coil circulating in the circulation pipeline at night, causing the temperature to decrease.
[0018] The utility model discloses a solar collector efficiently collects solar energy, and stores the excess heat energy generated during the day through the phase change heat storage layer, can maintain indoor temperature at night, and improves energy utilization efficiency. The heat is stored in the phase change heat storage layer below the floor, not only the heat dissipation amount is big, and directly releases to the indoor in the form of floor heat dissipation, improves the comfort degree of indoor environment.
[0019] The foregoing is each preferred embodiment of the utility model, and each preferred embodiment can be arbitrarily stacked and combined if not obviously self-contradictory or with a certain preferred embodiment as a prerequisite. The embodiments and specific parameters in the embodiments are only for clearly describing the utility model verification process of the utility model person, and are not used to limit the patent protection scope of the utility model. The patent protection scope of the utility model is still subject to its claims, and any equivalent structural changes made by using the content of the utility model specification should also be included in the protection scope of the utility model.
