Cooling-heating-integrated double-capillary-tube-layer phase-change energy storage floor terminal device and application system

Abstract

The invention relates to a cooling-heating-integrated double-capillary-tube-layer phase-change energy storage floor terminal device and an application system. The cooling-heating-integrated device combining a traditional capillary tube radiant cooling / heating with the phase-change energy storage technology comprises a ground source heat pump, a water distributor, a water collector, a solar heat collector, an auxiliary electric heater and an energy storage floor. The energy storage floor comprises a floor surface layer, a concrete layer, a heat storage phase-change material layer, a cement mortar screeding layer, a cool storage phase-change material layer, a reflecting film and an insulating layer from top to bottom, wherein the heat storage phase-change material layer is used for storing heat at night in winter, the cement mortar screeding layer is used for separating the heat storage phase-change material layer from the cool storage phase-change material layer and facilitates laying of the phase-change material layers, the cool storage phase-change material layer is used for storing cool at night in summer, the reflecting film is used for reflecting and blocking heat to decrease heat exchange between the cool storage phase-change material layer and the insulating layer, and the insulating layer is made of materials low in heat conductivity and small in density and used for further decreasing heat loss of floor structural layers. Capillary tubes are laid in the heat storage phase-change material layer and the cool storage phase-change material layer to be used for supplying hot water and cool water respectively.
