Phase change heat storage floor radiation device capable of preventing overheating

Abstract

The invention relates to the technical field of floor heating systems and provides a phase change heat storage floor radiation device capable of preventing overheating. The phase change heat storage floor radiation device comprises a structural layer, a thermal insulating layer, a phase change heat storage layer, an overheating preventing layer and a floor layer, wherein the structural layer, the thermal insulating layer, the phase change heat storage layer, the overheating preventing layer and the floor layer are sequentially overlapped together from bottom to top; and the overheating preventing layer comprises hot bimetallic strips, and the hot bimetallic strips are distributed between the phase change heat storage layer and the floor layer from the left to the right at intervals. Through promoting the hot bimetallic strips heated to have curved deformation, the thermal resistance of the overheating preventing layer can be increased, heat losses are reduced, and indoor overheating is prevented. When temperature suffered by the hot bimetallic strips is lower than the lower threshold, through restoring the hot bimetallic strips and promoting the hot bimetallic strips to be in contact with flexible heat conducting strips, heat radiation is promoted, and heat transmission efficiency is increased. Therefore, the regulation of heat radiation can be realized, and the keeping of a constant indoor temperature range is facilitated. Besides, through storing excessive heat and releasing the excessive heat when needed, resource wastes can be avoided, indoor temperature fluctuation can be effectively prevented, the range of temperature differences is reduced, and the comfort of users is improved.

Description

technical field [0001] The invention relates to the technical field of floor heating systems, and relates to a phase-change thermal storage anti-overheating floor radiation device. Background technique [0002] Existing floor heating systems mostly use floor heating coils for direct heating, which cannot regulate the heat dissipation. Once the temperature of the heat supply source is too high, the indoor temperature will be too high; Influenced by various factors, it cannot be kept constant. When the heating temperature is low, the indoor temperature will also drop, which will affect the user's comfort and make them feel that the room temperature is hot and cold; especially when the solar heating system is used , because of the discontinuity of solar energy, there is sufficient sunlight at noon, but there is no sunlight at night, which leads to the problems of excessive indoor temperature difference and poor comfort. At the same time, because it cannot store excess heat, us...
