Solar floor heating and energy-storage heat-supply embedded layer combined heating system

Abstract

The invention discloses a solar floor heating and energy-storage heat-supply embedded layer combined heating system. The solar floor heating and energy-storage heat-supply embedded layer combined heating system comprises a solar panel, a floor heating system connected with the solar panel, embedded layers installed on the indoor peripheral walls, annular thin tubes arranged between the embedded layers and the walls, and one or more heating tubes arranged in the embedded layer on each wall. The output ends of the annular thin tubes are connected to the solar panel. The embedded layers are made from phase-change materials. According to the solar floor heating and energy-storage heat-supply embedded layer combined heating system, when solar heat is gathered, heating can be provided for the floor heating system, a radiator and an air conditioner, and heat can be provided for domestic hot water; meanwhile, heat can be sent to the embedded layers for heat insulation, heating can be provided for the indoor floor and the indoor peripheries, and the comfort of a whole room is improved; and when the temperature falls, the embedded layers can be used for heating the annular thin tubes, the whole circulating system can operate, and the solar panel is prevented from being frozen off at the same time.

Description

technical field [0001] The invention relates to a phase-change energy storage device, in particular to a combined heating system for solar floor heating and energy storage heating embedded layers, and belongs to the technical field of phase-change energy storage. Background technique [0002] Phase change materials have the ability to change their physical state within a certain temperature range; taking solid-liquid phase change as an example, when heated to the melting temperature, a phase change from solid to liquid occurs. During the melting process, the phase change material Absorb and store a large amount of latent heat; when the phase change material is cooled, the stored heat will be dissipated to the environment within a certain temperature range, and a reverse phase change from liquid to solid is carried out; in the two phase change processes, all The energy stored or released is called phase change latent heat; when the physical state changes, the temperature of t...

Problems solved by technology

[0002] Phase change materials have the ability to change their physical state within a certain temperature range; taking solid-liquid phase change as an example, when heated to the melting temperature, a phase change from solid to liquid occurs. During the melting process, the phase change material Absorb and store a large amount of latent heat; when the phase change material is cooled, the stored heat will be dissipated to the environment within a certain temperature range, and a reverse phase change from liquid to solid is carried out; in the two phase change processes, all The energy stored or released is called phase change latent heat; when the physical state changes, the temperature of the material itself remains almost unchanged before the phase change is completed, forming a wide temperature platform. The classification of phase change materials mainly includes inorganic PCM , organic PCM and composite PCM; among them, inorganic PCM mainly includes crystalline hydrated salts, molten salts, metals or alloys, etc.; organic PCM mainly includes paraffin, acetic acid and other organic substances; composite phase change heat storage materials Emerged as the times require, it can not only effectively overcome the shortcomings of a single inorganic or organic phase-change heat storage material, but also improve the application effect of phase-change materials and expand its application range; existing phase-change materials are generally used in electric storage It can be heated on equipment, but it is difficult to heat at the same time as the existing heating system
