In some embodiments of the present invention, the phase transition temperature of the first flexible phase change material layer 210 is 15-20 ℃, and the phase transition temperature of the second flexible phase change material layer 220 is 25-29 ℃. It can be understood that the conventional phase transition temperature range is adopted here, and those skilled in the art can change the phase transition temperature range of the flexible phase transition material according to the actual situation of the local air temperature, so as to meet the purpose of storing and releasing energy, and achieve the requirements of cooling and heating.
In some embodiments of the present invention, a pipe 600 is disposed between the first flexible phase change material layer 210 and the second flexible phase change material layer 220, and the pipe 600 is provided with a water inlet 610 and a water outlet 620. The water flow channel is provided by arranging the pipeline 600, and water flowing through the pipeline 600 can be used as a cold source or a heat source according to the water temperature, so that the effects of cooling and heating are achieved. For example, in chilly winter in the north, use the utility model provides a double-effect radiation floor based on flexible phase change material, through the boiler, warm up, modes such as heat supply network, produce a certain amount of hot water entering cladding pipeline in flexible phase change material layer, the hot water that gets into the rivers passageway is as the heat source, can provide the heat for flexible phase change material, flexible phase change material begins to melt this moment, according to the phase transition principle, melt the heat absorption, the heat just stores in flexible phase change material layer like this, can release when the temperature descends, maintain indoor temperature. If so, in summer of southern hot, use the utility model provides a double-effect radiation floor based on flexible phase change material can link to each other the outlet conduit of central air conditioning cooling water set with the water inlet of pipeline, makes the cold water that central air conditioning provided as the cold source, can provide cold volume for flexible phase change material, and flexible phase change material begins to solidify this moment, and according to the phase change principle, it is exothermic to solidify, and cold volume just so stores in flexible phase change material layer, can release when the temperature rises, slows down the rising of indoor temperature.
In some embodiments of the present invention, the conduit 600 is in the shape of a serpentine or spiral disk. It is understood that the size and number of the pipes 600 are determined according to the area size of the floor, and the shape of the pipe 600 is preferably designed in a serpentine or spiral disk shape, so that the heat distribution is more uniform.
