Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a floor heating system, and more particularly to a floor heating system that uses a heat storage material and a heating means and maintains heat mainly by the heat of solidification of the heat storage material.

C. Prior Art] As an indoor heating device, a special composition with large latent heat is used as a heat storage material, and after the heat storage material is heated and melted, heat is retained by the solidification heat (latent heat) released when the heat storage material solidifies. A floor heating system has been proposed.

Examples of the heat storage material include sodium sulfate decahydrate (Na2SO4.10H20, also called Glauber's salt),
Materials having a predetermined melting point (for example, 25° C. to 60° C.) can be used, such as calcium chloride or sodium acetate-based M heat material.

In addition, heating means for this heat storage material include hot water pipes, heater wires made of electrical resistance wires, high-temperature planar heating elements printed or etched with metal or carbon, or electrical resistance materials made of resin mixed with conductive powder. Any material can be used, such as a low-temperature planar heating element formed from a sheet.

The latent heat of the mirabilite is, for example, 40 to 45 kcal/kg.
Once it is melted, it gradually releases a large amount of heat over a long period of time at a nearly constant temperature when it solidifies, so it maintains the room at a comfortable temperature (for example, 20°C) for a long period of time (for example, about 10 hours) even after heating. It can be kept at a temperature of ~25°C.

By the way, in a conventional latent heat type floor heating device of this type, the heating means is installed adjacent to the latent heat material (usually housed in a case such as a plastic case) in a desired distribution state. Ta.

However, with such a conventional structure, it is difficult to uniformly heat and melt the latent heat material, and when high-temperature heating means are used, the temperature of some parts of the latent heat material may rise rapidly, or the latent heat material may not melt due to the high temperature. There is a problem in that the case is damaged, and in order to avoid these problems, the type and structure of the heating means are extremely limited, and the design and construction are restricted.

〔the purpose〕

The present invention has a configuration in which a heating means is installed on the floor, a thermal interference zone is provided at a predetermined interval on the heating means, and an N heat material is installed on the thermal interference zone, that is, a heat storage material and a heating The above object is achieved by providing a thermal interference zone at a predetermined interval between the device and the device.

It is preferable that the thermal interference zone is formed of a layer with relatively small thermal conductivity, such as a mortar layer, a felt layer, or a space, and the thickness (interval) thereof is set within the range of 5 to 30 fins.

〔Example〕
