Description

[Detailed explanation of the invention] Purpose of the invention A: Industrial application field This invention is an economical and efficient method that can easily provide underfloor heating to any type of building such as residences, offices, stores, and meeting halls. This relates to a floor panel for floor heating that can provide heating.

B. Conventional technology and its problems A. Conventional built-in floor heating takes a long time to construct, has high equipment costs, has poor fuel conductivity, and has high running costs, so it cannot be called economical heating.

(b) With conventional floor heating panels, the floor heating panel twists due to the difference in heat load resistance, and since the floor heating panel is fixed to the joists with needles, the needles may come off due to temperature changes. , carpets, jerseys, etc. are often damaged.

C. With conventional floor heating panels, the floor surface temperature is not proportional to the room temperature, making the floor surface extremely hot, so it is difficult to say that it provides comfortable heating.

D. Conventional heated floor panels do not have heat storage properties and must be operated continuously, making them difficult to call economical.

Structure of the invention A: Means for solving the problem The purpose of this invention is to easily provide underfloor heating to any type of building, such as residences, offices, stores, and meeting halls, and to provide economical and efficient heating. That is. In order to achieve this objective, the present invention was completed with the following points in mind.

Point 1: By unitizing the functions of floor heating and flooring, design and construction can be standardized and simplified, reducing the time and effort required for design.
This will significantly shorten the construction period and save labor.

Second point: Construction is possible for all targets. Namely, new construction;
Can be installed on existing buildings, first floors, second floors, Western-style rooms, Japanese-style rooms, wooden structures, reinforced concrete private residences, apartment complexes, especially in cold regions.

Third point It is durable enough to be used as a flooring material.

4th point: Underfloor heating equipment costs are stable and construction can be completed in a short time.

5th point: Twisting or misalignment of floor heating panels due to temperature changes.
There are no creaks or other malfunctions.

Point 6: Sunlight from the windows during the day accumulates heat in the floor heating panel, and when the sunlight disappears, heat is radiated from the floor heating panel, making it an energy-saving panel.

Point 7: It has an excellent heat storage effect, stabilizes indoor temperature changes, and slows down the rate of room temperature drop even after heating is stopped, providing comfort and energy saving effects.

B. Embodiment of the invention FIG. 1 is a plan view showing a state in which floor heating panels 7 are installed at a desired heating location 1, in which 2 is a pipe connecting the floor heating panels 7 to each other, 3 is a heat source boiler, 4 and 5 indicate the outgoing pipe and return pipe from the heat source boiler to the floor heating panel, respectively.

FIG. 2 shows a cross section of the state shown in FIG. 1 when the spaces between the floor heating panels, the gaps between the floor heating panels and the walls, etc. are filled with concrete mortar 6.

Therefore, the structure of the floor heating panel 7 is as follows.

A copper pipe 7B is arranged in a planar meandering manner at the center of a laminated pressurized concrete plate 7A containing a mixture of high-density natural stone and aluminum particles, and the lower surface of the copper pipe is in contact with the copper pipe. Vertical and horizontal reinforcing bars 7C and 7D are installed. 7E is a notch that exposes the connecting ends 7B', 7B'' of the copper pipe 7B. Also, for the panel 7, the ends 7B', 7 are cut out for convenient piping work.
It is preferable to manufacture an A-type panel 7' and a B-type panel 7'' with different exposure directions of B''. In the figure, 8 is a large drawer, 9 is a heat insulating material such as glass wool filled in this large hole, and 10 is Styrofoam (trademark).
11 is a cushion floor or carpet, 12 is a room, and 12A is a window through which sunlight enters.

C About the experiment A Condition of the experiment Test location 5-chome Mihara, Kushiro City Test date S59.1.21 - S59.2.22 (32 days) Building floor area 1st floor 61.66m ² 2nd floor 63.39m ² Total 125.04m ² (38 tsubo) Architectural use: Residential (wooden mortar) Family composition: Couple, 2 children Floor heating panel installation status: Floor heating living room 17.10 m ² , Number of floor heating panels installed: 16
The floor heating installation area is 63% of the room area, and the floor heating surface finishing material is Jyutan 7m/m throughout.
A 7m/m thick piece of sweatshirt mat is laid all over the floor as a cushion material under the sweatshirt.

Floor heating kitchen ^9.99m2 , number of floor heating panels laid 6
The floor heating area will be 40% of the room area, and the floor heating surface finishing material will be a cushion floor covering of 2.2 m/m.

Floor heating panels will be connected using U-bent copper pipes with silver brazing.

Floor heating panels and spaces will be embedded with concrete mortar. The main pipes will be arranged in a series for each room using the Hettar method.

Heat medium: Use a 30% antifreeze mixture as the heat medium.

Heat source 31000kcal/h2 can type hot water simultaneous boiler Heat medium temperature 40℃~60℃ Measuring instrument CHINO EH100−06 Wire color Black Outside temperature Purple Boiler room (indoor temperature) Red Heating room temperature (living room) Light blue Heating room floor temperature Green Heating forward Brown Heating return B Experimental results A partial report during the measurement period is as follows.

When the outside temperature is -20°C, if the heating medium temperature is 60°C for 2 hours (from 5am to 7am), the room temperature will rise from 16°C to 23°C. Average outside temperature until 5pm in the evening -
The temperature was 10 degrees Celsius, and the boiler was shut down at 7 a.m. until 5 p.m. The boiler was not run once, but due to the heat stored in the floor heating panels, the room temperature remained at 18 degrees Celsius even at 5 p.m. When the heating medium temperature was passed through the boiler again at 60°C for 1.5 hours (from 5:00 pm to 6:30 pm), the room temperature rose to 24°C, and although the boiler was stopped until 5:00 am the next morning, the room temperature remained at 16°C. The outside temperature was -20℃. It has been proven that floor heating panels have a long heat storage capacity.

Effects of the invention A: It is robust. Durable enough to be used as flooring material.

(b) Construction is fast. The entire room becomes a hot zone. It is economically efficient because the floor heating panels equivalent to a room are laid down, and the spaces between the floor heating panels and the gaps between the floor heating panels and the walls are filled with concrete mortar and the entire floor becomes a heating zone. .

C. There are no twisting, curling, or squeaking sounds in the floor heating panel due to differences in hot water temperature or room temperature, and there are no malfunctions.

(d) It can improve heat conduction and heat storage effects, stabilize indoor temperature changes, and slow the rate of room temperature drop even after heating has stopped, providing sufficient comfort and energy-saving effects.

E. It has a special heat storage structure, so the room temperature rises quickly, and even after the heat source is stopped, there is little difference between the room temperature and the floor temperature, so there is no temperature unevenness.

F. In the case of extensions and renovations, repairs and additions can be made without destroying the building.

G. Heat from the sunlight during the day is stored in the floor heating panels, and in the evening when there is no sunlight, the room temperature does not drop due to the heat released by the floor heating panels, and it also acts as a natural humidity regulator, so the humidity is always almost constant. It is also a feature.
