Abstract

PURPOSE:To eliminate the need for maintenance practice to prevent the generation of piping corrosion, the leakage of radiation water or supplement the radiation water, by carrying out indirect heat exchange between combustion gas generated in an outdoor combustion device and indoor circulation air by way of a heat exchanger so that they may be discharged indoors from a floor panel. CONSTITUTION:A heat exchanger 13 is designed to perform indirect heat exchange between combustion gas generated in a combustion device 1 installed outdoors A and indoor circulation air sucked up by an indoor air circulation fan 16. The heated air is adapted to be discharged indoors from a spout 23 of a floor heating panel 2 so as to heat a room. This construction uses the indoor circulation air as a heating medium, eliminating the penetration of the combustion gas indoors, which makes it possible to improve the safety of the heating device. Furthermore, the heated air is spouted out indoor uniformly, which also improves the distribution of temperature.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for converting indoor circulating air that is indirectly heated through a heat exchanger that is heated in a combustion device installed outdoors into a combustion device installed indoors. The system is designed to supply heat to a radiant surface-type floor heating panel.

[Prior Art] Fig. 3 is a cross-sectional view of a conventional outdoor heating device.
) A combustion device for heating outdoors (A), (3) a distern for heated water, (4) a pump for circulating heated water,
(5) is the heating water piping, (6) is the heat radiation panel installed in the room (B), and (7) is when heating from this heat radiation panel (6) alone is insufficient or when the indoor temperature rises faster. (8) is the heat exchanger inside this indoor unit, (9) is the indoor air convection fan installed directly below this heat exchanger, (1,0) is the above A heat exchanger plate (11) installed on the pipe (5) so as to be located inside the heat radiation panel (6) is branched from the pipe (5) and conducts heated water into the heat exchanger (8) in the indoor unit. It is a distribution pipe.

Next, the operation of the above-mentioned conventional device will be explained.

First, we will explain the basic case where only floor heating is used.

The heat generated in the combustion device (1) is transferred by a heat exchanger (2) to the heated water inside it, which is stored in a small-capacity distern (3), and the heated water therein is After reaching a certain temperature, the pump (4) connects the pipe (5).
) into the heat dissipation panel (6), is transmitted to the entire floor surface via the heat transfer plate (10) at the tip, and is radiated into the room by natural convection. Then, the heated water that has received heat from the heat dissipation panel (6) returns to the heat exchanger (2), where the temperature rises again and the above-mentioned circulation is repeated.

Next, when the indoor unit (7) is added, the heated water whose temperature has risen will flow at a constant rate to the distribution pipe (11) branched from the middle of the pipe (5), and will flow indoors via the heat exchanger (8). Heat is exchanged with the air, and the hot air is sent into the room by a convection fan (9), and the heated water that has cooled down here is heated again in the heat exchanger (2), and is stored in the distiller (3), where the above circulation is carried out. Repeated.

[Problems to be Solved by the Invention] Conventional heating devices use heated water such as antifreeze fluid, which causes problems such as corrosion of pipes, leakage of heated water, and the need for maintenance such as replenishment. there were. This invention was made to solve the above problems, and uses hot air as a heat medium.

[Means for Solving the Problems] In the case of the present invention, indoor circulating air heated indirectly through a heat exchanger heated in a combustion device installed outdoors is transferred to a floor installed indoors. It is supplied to the inside of the heating panel.

[Function] In the case of this invention, heat is radiated from the surface of the floor heating panel installed indoors, and warm air is blown out from the numerous blow-off holes provided in the panel, causing indoor air to convect. Increase temperature.

[Example] An example of the present invention will be described below. In other words, in Fig. 1, (1) is the combustion device installed outdoors (A), (12) is the burner inside it, (13) is the heat exchanger installed above this burner, and (14) is the combustion device installed outside (A). A wind tunnel (15) installed in the combustion device (1) so as to surround the burner (12) passes the gas combusted in the burner (12) into the wind tunnel (14).
) An exhaust pipe that exhausts the combustion device (1) to the outside while being isolated from the inside, (16) is a fan for indoor air circulation installed on the upstream side of the wind tunnel (14), and (17) is its inlet duct that exhausts the air indoors. is communicated with. (18) is this inlet duct (
17) is an air filter provided on the indoor side, and (19) is a heat exchanger (13) provided downstream of the wind tunnel (I4).
This is an exit duct for guiding the warm air heated by the air into the room, and it communicates with a hollow floor heating panel (20) laid on the floor of the room (B). And this floor heating panel (
20) has an aluminum sheet (21) with good heat conduction on the top.
and its surface is made of fiber cloth (2)
2), and a large number of blow-off holes (23) for the supplied high-temperature indoor circulating air are opened in the surface, and the indoor air blown out from these holes is made to circulate. Furthermore, an appropriate amount of metal oxide that efficiently emits far infrared rays is fixed to the surface of the carpet-like fiber cloth (22).

(24) on the map is the above air filter (18)
The sensor installed inside the room controls the amount of heat generated according to the rise in room temperature, and controls the room temperature to the desired temperature.

When heating operation is performed in the above configuration, the burner (12
) The high temperature gas combusted in the heat exchanger (13) passes through the heat exchanger (13) and is discharged outdoors from the exhaust pipe (15). On the other hand, the indoor air sucked by the indoor air circulation fan (16) undergoes heat exchange in the heat exchanger (13), reaches a high temperature, and flows into the floor heating panel (20).
) emits far-infrared rays from the surface, and hot air is blown out from a large number of blow-off holes (23) provided on its circumferential surface. Thereafter, the indoor air passes through the air filter (18) and the inlet duct (17) again to the indoor air circulation fan (16).
), is reheated and blown out into the floor heating panel (20), and the circulation is repeated in this way.

Note that in the above embodiment, the inlet duct (17) and the outlet duct (
18) are provided in parallel, but these ducts may be made into double pipes as shown in another embodiment of FIG. With this configuration, the high-temperature outlet duct does not touch the wall surface, so there is no need to provide insulation material around it, and only one torch is required, making piping work easier.

[Effects of the Invention] Since the heating device of the present invention is constructed as described above, the following effects can be obtained.

(1) Since heat is radiated from the surface of the floor heating panel and heating is performed with hot air blowing out from the panel at the same time, the indoor temperature distribution is improved.

(2) Even if the airtightness of the duct or floor heating panel deteriorates and the heat medium leaks, it is safe because it is air.

(3) Since the heat medium is indoor circulating air, there is no need for maintenance such as corrosion of ducts or replenishment.
