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.

Description

technical field [0001] The invention is an integrated terminal device and an application system that combines traditional capillary radiation cooling / warming and phase change energy storage technology, and belongs to the field of building heating and air-conditioning new technologies, and the field of building energy optimization utilization and energy storage technology . In particular, it relates to the structural design of a novel energy storage floor. Background technique [0002] Floor radiant cooling / heating has been developed to this day, no matter from theoretical research or engineering practical application, it is constantly maturing and has achieved great development. Capillary floor radiation system, as a new type of air conditioning with low-temperature hot water and high-temperature cold water, can better create a comfortable environment, improve indoor air quality, and conform to the development direction of energy conservation. Moreover, with the continuous...
