In some cases, a heat source such as a heating wire such as a heating cable or an electric heating sheet is installed separately using each electric power as a power source, and the power is turned on by separately detecting the floor surface temperature or indoor temperature during each use time. has been controlled.

、一般料金電力の使用を極力抑える必要がある。Problems to be Solved by the Invention〉 Discounted electricity or snow melting electricity from the ``Commercial Thermal Storage Adjustment Contract System'' can be used as a heat source by energizing an electric heater, etc.
In a regenerative electric floor heating system that uses a heat storage material, when the amount of heat storage is insufficient and the heat supply from the floor is insufficient, such as in the afternoon of a bitterly cold season, heat is supplied indoors by some method. There is a need for what is called "rekindling." With conventional concrete heat storage, when this "reheating" is performed, heat can be supplied to the room, but at the same time, heat is also stored in the concrete, and as a result, there is less room for heat storage during the period when discount rate electricity is on. Even in floor heating systems that use latent heat storage materials, there are cases where there is almost no difference between the melting temperature and solidification temperature,
A similar situation occurs when the temperature of the latent heat storage material in the container is uneven. If "reheating" is performed using a separate heater, the feeling of heating will be different and it will be expensive to purchase the heater, which is not desirable. In order to keep the maintenance costs required for floor heating low, it is necessary to make maximum use of discount rate electricity to store heat and to minimize the use of regular rate electricity.

ことが必要である。In order to achieve the above objective, the temperature of the heat storage material needs to be maintained uniformly at a desired temperature such as melting temperature or solidification temperature. Furthermore, the mounting position of the temperature detector that detects these temperatures needs to be able to accurately detect the temperature of the heat storage material.

し易いという問題がある。In a latent heat storage type electric floor heating system that uses in-floor or floor heat storage, the solidification temperature of the latent heat storage material is from 22℃ to 2.
Approximately 80'O is appropriate to maintain the melting temperature at around 8°C, but if you raise the melting temperature, there is a greater risk of low-temperature burns if you sleep with a futon on the floor late at night when discounted electricity is supplied. Another problem is that floor finishing materials are susceptible to thermal deformation.

硝系潜熱蓄熱材を例示することができる。Means for Solving the Problems> The present invention has been made to achieve the above problems, and is characterized by using a latent heat storage material having a difference of at least 2°C between its melting temperature and solidification temperature. Regarding the heat storage type electric floor heating system, the heat storage material is not particularly limited as long as there is a difference of 2°C or more between the melting temperature and the solidification temperature, and the solidification temperature is in an appropriate temperature range. . For example, a mirabilite-based latent heat storage material obtained by blending a second component with mirabilite or mirabilite can be exemplified.

体的な構成は次のとおりである。Heat storage in the latent heat storage material is normally carried out at night using discounted electricity at a reference temperature of the melting temperature or higher, while regular electricity is used to maintain the floor temperature. To this end, the power supply to heaters that use general electricity is controlled by setting the solidification temperature below the melting temperature of the latent heat storage material as the reference temperature, and turning it off when it exceeds this temperature, and turning it off when it is equal to or below this temperature. is on. A more specific configuration of the device is as follows.

るように取り付けた温度検知器で行うこととする。In an in-floor or floor heat storage type electric floor heating system, in order to uniformly maintain the temperature of the latent heat storage material at the desired temperature, the container that stores the latent heat storage material is shaped like a plate with a thickness of 10 m to 80 m. The heater for melting the latent heat storage material is a rectangular parallelepiped, and either a planar heater that is in close contact with the latent heat storage plate or a linear heater that is uniformly arranged and has good heat transfer to the latent heat storage plate is used. Temperature detection will be performed with a temperature sensor installed in a groove provided in a surface opposite to the surface of the plate-shaped rectangular parallelepiped container that is in contact with a heat source such as an electric heater.

快適な床暖房による室内環境が得られる。According to the present invention, it is possible to reduce the possibility of heat storage using regular rate electricity and to make maximum use of discount rate electricity for heat storage. In addition, there is no difference in floor temperature during normal heating due to heat dissipation from the heat storage material and during "reheating", so there is no difference in the feeling of heating.
Enjoy a comfortable indoor environment with underfloor heating.

にくくなる。In addition, with an in-floor or floor heat storage type electric floor heating system, the floor surface temperature does not rise too much when electricity is supplied at a discounted rate late at night, so there is less risk of low-temperature burns and the floor finishing material is less likely to become distorted.
