Abstract

PROBLEM TO BE SOLVED: To provide an electric heat storage heater to heat a heat resisting brick during the night and radiate it during the daytime as arts to effectively utilize a surplus power or a floor heating system to make a concrete plate right below a floor material and arrange a hot water pipe and an electric wire at an internal part to warm the concrete plate but the former has a problem that indoor air becomes abnormally dry and when a forced feed of hot water is stopped, a room temperature is reduced. SOLUTION: Cobble gravel is laid in a given thickness right below a floor material and warmed by hot water to constitute a heat storage type floor heating.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a regenerative floor heating system using debris.

[0002]

2. Description of the Related Art Conventionally provided one has the following configuration. 1. As a technology for effective use of surplus electricity, heat-resistant bricks
There is an electric heat storage heater that heats at about 00 ° C. with electric power at night and dissipates it during the day to use as heating. 2. There is a regenerative floor heating system that builds a concrete plate directly under the floor finishing material, arranges hot water pipes and heating wires inside it, and warms the concrete plate.

[0003]

The above-mentioned prior art has the following problems. 1. The problems of the conventional electric heat storage heater are as follows. A. In the electric heat storage heater, the indoor air dries abnormally. B. Since the heat storage material is at a high temperature (700 ° C.), it is necessary to devise heat insulation. 2. The problems of the conventional regenerative floor heating system are as follows. In floor heating using a concrete plate, when the supply of hot water stops, the room temperature drops in about 2 to 3 hours.

The present invention has been made in view of the problems of the prior art, and has as its object to provide the following. 1. Abnormal drying is suppressed in the indoor humidity by the regenerative floor heating at a low temperature (50 ° C. to 75 ° C.) instead of the thermal storage heating at a high temperature (700 ° C.). 2. In the present invention, since the heating is performed at a low temperature (50 ° C. to 75 ° C.), a special heat insulating material for preventing danger of the heat source portion is unnecessary. 3. It has long been said that gravel is a material with good heat. Utilizing this characteristic, it is intended to be used for floor heating as a low-temperature heat storage material. In addition, as a result of experimenting the cobblestone and the concrete plate under the same condition, the rate of temperature decrease immediately below the floor and at the center of each material was as shown in FIG. This phenomenon is consistent with the difference in the heat time constant of the material. By the way, in the case of the gravel, no decrease in the room temperature is observed until 5.5 to 7.5 hours after the hot water pumping stops. 4. The purpose of the present invention is to utilize the surplus electric power effectively by utilizing the characteristic that the gravels have a longer heat radiation time than the concrete plate or the like in the heat time constant.

[0005]

Means for Solving the Problems In order to achieve the above object, the present invention is as follows. The invention according to claim 1 is characterized in that, in floor heating of a building, gravel is disposed at a predetermined thickness immediately below a floor finishing material, and it is heated with warm water to form a heat storage type floor heating. is there. Claim 2
The described invention is characterized by arranging a hot water pipe on the upper surface of a structural floor in a wooden house, wrapping it with gravel, and covering the upper part with a floor finishing material to provide a regenerative floor heating system. According to a third aspect of the present invention, a hot water pipe is arranged on the upper surface of a structural floor of a building such as a concrete structure, wrapped with cobblestone, and its upper part is covered with a floor finishing material to provide a regenerative floor heating system.

The operation is as follows. 1. A space of about 100 mm is created between the floor finishing material and the general structural floor, a hot water pipe is arranged in the space, filled with gravel, and hot water of 50 ° C. to 75 ° C. is pumped according to the room temperature. 2. The heat from the hot water pipe is stored in the gravel (combined material of 5 mm to 25 mm). 3. The hot water heated by the electric boiler 16 is sent to the heads 18 and 19 in each room through the electric valve 17. Further, the hot water is sent to the respective circuits from the respective heads of the respective rooms to warm the debris, and the heads 18A and 19H are heated.
Returning to A, it returns to the electric boiler 16. 4. As a method of utilizing the present invention, the boiler is turned on in the fall to warm the gravel in the floor. At the same time, the temperature is set by the room temperature controller 17A installed in each room, and the electric valve 1 is set.
7 is opened and closed to maintain the set room temperature. Turn off the boiler when heating is no longer needed in the spring. 5. The hot water temperature of the boiler depends on the outside air temperature at that time.
Adjust within the range of 0 ° C to 75 ° C.
