Abstract

PURPOSE:To make power supply not necessary and make the provision of a filter for preventing clogging unnecessary, by introducing the outside air taken through an air intake cylinder installed outside into a heat exchanger tank burried in the earth incorporating the top ends of heat pipes inserted into the earth and then feeding said air into the inside of a house, while discharging the inside air to the outside through a vertically installed discharge cylinder. CONSTITUTION:Heat exchange of the outside air at a base tank 3 and a heat exchanger tank 5 is performed in such a manner that in summer the outside air is cooled since the heat of the earth has lower temp. compared with the outside temperature and in winter it is heated since the heat of the earth is higher in temp. compared to the outside temperature; however, as the top ends of heat pipes 6 inserted into the earth are incorporated in the heat exchanger tank 5, heat exchange between the outside aid and the heat of the earth is performed more effectively. Further, by opening or closing properly opening and closing means provided on air inlet port 7, 7 and a connecting passage 14, ventilation or no ventilation, or the extent thereof is freely chosen, wherein power for a fan etc. is not required. Moreover, since the outside air passes through a relatively long passage from an air intake port 4 to the air inlet ports 7, and the base tank 3 is located under the lower end of an air intake cylinder 1, a filter for preventing clogging need not be placed on the inlet and outlet of the outside air passage.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an indoor ventilation method, and more specifically, to a method for indoor ventilation, and more specifically, to a method for ventilating indoor and outdoor air naturally, that is, by using outdoor wind force and temperature difference between indoor and outdoor. Regarding indoor ventilation methods.

[Conventional technology and problems]

As shown in Figure 2, an outer cylinder a with one end opened indoors and the other end opened outdoors is hung horizontally under the ceiling, and one end of the inner cylinder fitted inside this outer cylinder a is opened outdoors. An indoor ventilation method is known in which the other end is opened indoors, and outside air is taken in through the inner tube, while indoor air is exhausted through the outer tube a. According to this ventilation method, during the winter, the warm air discharged through the outer tube warms the cold outside air taken in through the inner tube, and during the summer, the temperature is lower than that of the indoor air taken in through the inner tube. The high temperature outside air will be cooled by the low temperature indoor air discharged through the outer cylinder a.

However, in the above case, it is necessary to install and operate an exhaust fan a' and an air supply fan b' at the indoor opening end of the outer cylinder a and the inner cylinder, for example, to promote ventilation, or to install a filter to improve ventilation. There was a problem in that clogging had to be prevented.

The present invention aims to provide an indoor ventilation method that does not require such a fan for promoting ventilation, that is, power, and also does not require a filter to prevent clogging.

[Means for solving problems]

Outside air taken in through an intake pipe installed outdoors is introduced into an underground heat exchange tank containing the head end of the Hee-I Vibe, which is inserted into the ground, and then sent indoors. An indoor ventilation method characterized by exhausting air through an upright exhaust stack.

[Effect]

Due to the draft effect that occurs between the exhaust stack and the intake stack, outside air is guided into the room and indoor air is exhausted outside, resulting in natural ventilation.

What's more, outside air is cooled in the summer and warmed in the winter by being exchanged with geothermal heat in a heat exchange tank buried underground.

〔Example〕

1 is a basic tank 3 (capacity: 0.5n()-H) buried under the eaves of house 2 (1.5m);
The intake port 4 at the upper end is located near the eaves. 5 is a heat exchange tank (volume 1.0%) buried in the basement of the house 2 (1 m), 6 is a heat pipe filled with a heat medium such as fluorocarbon gas, and its head end is inserted into the heat exchange tank 5. ing.

7.7 is an air supply port equipped with a suitable opening/closing device, and is connected to the room (
indoors). 8, 8 is the air supply lower, 7
This duct connects the heat exchange tank 5 and the heat exchange tank 5, and is installed under the floor and in the walls with the necessary heat insulation treatment.

Reference numeral 9 denotes an air supply passage connecting the basic tank 3 and the heat exchange tank 5.

Reference numeral 10 denotes an exhaust pipe installed upright on the opposite side of the house 2 to the side where the intake pipe 1 is located, and in this embodiment, the exhaust pipe 2 is formed by forming an exhaust passage 12 outside a central flue 11. Although we have shown an example of a heavy structure and shared use with a collective smoke stack, it may also be a dedicated exhaust stack consisting of only an exhaust path. Reference numeral 13 denotes an exhaust port which opens the upper ends of the above-mentioned flue 11 and exhaust passage 12 to the atmosphere, and is located above the roof.

Reference numeral 14 denotes a connection path that connects the lower part of the room and the exhaust path 12. An appropriate switch device is attached to the open end of the room, and the connection path 14 is designed to prevent indoor air from flowing into the exhaust path 12. Required dampers (not shown) are provided to allow but prevent opposing airflow.

A draft effect occurs between the exhaust pipe 10 and the intake pipe 1, and the outside air flows from the intake air D4 through the intake pipe 1 and flows into the basic tank 3, where it exchanges heat to some extent with the surrounding geothermal heat. At the same time, the air enters the heat exchange tank 5 through the air supply passage 9, and further heat exchanges with the surrounding geothermal heat via the heat vibro. In order to perform heat exchange more effectively in this heat exchange tank 5, it is recommended to fill this tank 5 with a heat storage material such as sand, gravel, or ceramics so as not to obstruct the flow of outside air. be.

The outside air that has entered the heat exchange tank 5 is sent to the room from the air supply lower 7 through the duct 8.8.

Further, the air in the room is sucked into the exhaust path 12 of the exhaust pipe 10 through the connecting path 14 opening at the bottom of the room, and is discharged into the atmosphere from the exhaust port 13.

- In the above, heat exchange in the outside air basic tank 3 and heat exchange tank 5 involves cooling the outside air in the summer because the geothermal heat is lower than the outside temperature, and cooling the outside air in the winter because the geothermal heat is higher than the outside temperature. Particularly, the heat exchange tank 5 has a built-in head end of a heat vibro inserted underground, so that heat exchange with geothermal heat is performed more effectively. In addition, by appropriately opening and closing the above-mentioned switching devices installed in the air supply lower 7 and the connection path 14, it is possible to freely select whether or not to ventilate and the degree of ventilation. No other power is required. Furthermore, the outside air is
Because it passes through a relatively long passage from the air intake lower to the intake air intake cylinder 7, and because the basic tank 3 is located at the lower end of the intake pipe 1, dirt, dust, sand, etc. in the outside air are particularly susceptible to Since the objects fall into the basic tank 3, there is no need to install a filter to prevent clogging at the entrance and exit of the outside air passage.

〔Effect of the invention〕

According to the present invention, indoor ventilation is performed smoothly due to the draft action between the intake pipe and the exhaust pipe, and in particular, after outside air is taken into the intake pipe, it is transferred to a heat exchange tank buried underground. The W4 end of the heat pipe inserted into the ground is introduced indoors through the built-in heat exchange tank, so the indoor air supply is cooled in the summer and warmed in the winter by heat exchange with the geothermal heat. This makes it an ideal indoor ventilation method.
