Abstract

PURPOSE:To enable utilization of exhaust heat for space heating and cold air under a floor during the summer season and to utilize exhaust heat for space heating with high efficiency, by a method wherein a duct is installed around an exhaust cylinder for space heating, and a suction port communicating with a position under a floor is formed in the lower part of the duct. CONSTITUTION:When the interior of a house is heated during winter days, the suction port 11 of a duct 10 is closed with a damper 12. The open air under a floor 4 is sucked through a suction port 8, and by heating a space heater 6, air in a first floor room and air in a duct 10 around an exhaust cylinder 9 are heated. By feeding air, heated in the duct 10, to a second floor room with the aid of a blast fan 18, a first and a second floor room can be heated. Further, during the middle seasons, e.g. spring and autumn, and during the summer season, the suction port 8 of the heater 6 is closed with a damper 12, and the suction port 11 of the duct 10 is opened. With fans 15 and 15 run, cooled air under a floor 4 is taken in a first and a second floor room through a suction port 14 or a blast port 17. This constitution enables cleaning of air in a room, and lowering of a room temperature to effect cooling.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an air conditioning structure for a house, and in particular, a duct is provided around a heating exhaust stack, and a heater and an intake port of this duct are installed on the floor. This relates to the air conditioning structure of the constructed house.

<Prior art> Conventionally, for example, in the Franklin Stove shown in FIGS. 5(A) and 5(B), fresh air is taken directly from the outside into the stove 2 through the pressure passage 1, and then indoors through the exhaust pipe 3, etc. The heating structure has been put into practical use. In addition, a double chimney system (not shown) is adopted in which ducts are arranged concentrically around the exhaust stack, and air warmed in the surrounding ducts is diffused into the room through a diffusion hood installed in the middle of the duct. A structure that heats a room by heating the room has also been put into practical use.

<Problems to be solved by the invention> However, since the above-mentioned conventional structure only takes into account heating in the winter, a completely separate device is required for cooling in the summer, which increases equipment costs and makes it difficult to utilize waste heat. There were problems such as low efficiency.

The air conditioning structure according to the present invention relates to a completely new technology developed in view of these conventional drawbacks.

<Means for Solving the Problems> The present invention installs the air intake port of the heater on the floor, provides a duct around the exhaust pipe of the bracket heater, and connects this duct with the under-floor air intake port and indoor ventilation port. This is an air conditioning structure for a house in which opening/closing dampers are installed at the inlet of the heater and the underfloor inlet of the duct.

<Function> As described above, in the present invention, the intake port of the heater is installed on the floor, and a duct is provided around the exhaust pipe of the heater, and this duct is connected to the underfloor intake port and the indoor ventilation port. In addition, dampers for opening and closing were installed at the air intake of the heater and the underfloor intake of the duct, so during the Chinese and summer seasons such as spring and autumn, the cooled air under the floor can be taken indoors through the air intake and the duct. It can freshen the air in the room and cool it at the same time.

〈Example〉To specifically explain one embodiment of the air conditioning structure according to the present invention with reference to the drawings, in Figs. 5 is provided. 6 is a heater installed on the floor 7 of the first floor,
The floor 7 has an air intake port 8 that allows communication between the heater 6 and the underfloor 4.
is provided. Reference numeral 9 denotes an exhaust pipe of the heater 6, which is installed vertically inside the building, with its tip protruding outward from the roof, and around the exhaust pipe 9 is an air conditioning duct 1.
0 are provided concentrically. An intake port 11 communicating with the underfloor 4 is provided at the lower end of the duct 10, and a damper 12 is provided at the intake port 11 and the intake port 8 of the heater 6 to alternately open and close them. Further, a fin type heat exchanger 13 is attached to the upper part of the duct 10. The floor 7 is provided with an indoor intake port 14 that communicates with the underfloor 4, and an intake fan 15 is attached to this portion. Furthermore, the duct 10 is installed on the floor 16 of the second floor of the building.
A plurality of ventilation ports 17 are provided which communicate with each other, and a ventilation fan 18 is attached to the ventilation ports 17.

Also, an air outlet 19 similar to the floor 16 is provided in the ceiling of the second floor (in this case, it sends air from the room to the duct 10).

Next, the operation of the air conditioning structure according to the present invention will be explained.
First, when heating indoors in winter, as shown in Figure 2,
The damper 12 closes the intake port 11 of the duct 10, and while the outside air from under the floor 4 is taken in from the intake port 8, the heater 6
1 by heating the room on the first floor and the air in the duct 0 around the exhaust pipe 9, and sending the warmed air in the duct 10 to the room on the 2nd floor via the ventilation fan 18.
Each room on the first and second floors can be heated.

Furthermore, during the spring, autumn, and summer seasons, as shown in FIG. The cooled air under the floor 4 is taken into the rooms on the first floor and each room on the second floor through the opening 14 or the ventilation opening 17, thereby making it possible to freshen the air in the room and lower the temperature of the room for cooling.

In the air conditioning structure according to the present invention, as shown in FIGS. 4(A) and 4(B), the above-mentioned underfloor 4 is made into a raised floor structure with concrete walls, and this air conditioning structure 5 can be opened and closed along the outside air intake port 5. It is also possible to provide a sand protection embankment 21 to prevent sand from flowing into the damper 20 and the underfloor 4, and further to provide a partition plate 22 for the purpose of increasing the air cooling effect by lengthening the air circulation path.

<Effects of the Invention> As mentioned above, the air conditioning structure according to the present invention is provided with a duct around the heating exhaust stack and an intake port that communicates with the underfloor at the bottom of this duct, so that the underfloor cooling is carried out from this part. Air can be taken into the duct and cooled air can be circulated indoors through the duct, making it possible to utilize waste heat from heating and cool air under the floor in the summer. Because the system is connected to the house through the system, waste heat from heating can be used extremely efficiently, and heating and cooling equipment can be installed in an integrated manner, which reduces construction costs. It is something that you have.
