JPH0289935A - Air conditioning and ventilating device for house - Google Patents

Abstract

PURPOSE:To allow a natural ventilation which is warm during the winter and cool during the summer by using the geotherm by burying an air supply pipe at a required depth in the ground under the floor, one end of which is open to the under-the-floor space or at any point in the ground surface and the other end connected to the air supply opening disposed in the floor. CONSTITUTION:In a house 1, the air supplied through an air supply opening 3 in the floor 2 flows through the rooms R1, R2, R3... serially or selectively through the vent opening 4 to be released out of the air discharge opening 5 or air discharge duct 10. One end of the air supply pipe 12, which is buried at a required depth in the ground under the floor, is connected to the air supply opening 3 in the floor 2, and the other end of it is opened to the under-the-floor space or at any point away from the house 1. As the air flowing through the air supply pipe 12 exchanges heat with the ground heat, its temperature tends to be higher during the winter, and lower during the summer than the atmo spheric temperature, and so, it becomes possible to concurrently perform the natural ventilation and the air conditioning in the house.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is directed to an air system for a house that utilizes geothermal energy under the floor.

[Conventional technology]

House number 1! ! ! There is a method in which air is supplied from under the floor as an air system, rises through the room with air currents, and is exhausted from a ventilation chimney installed on the roof.

This has the advantage of allowing natural ventilation even when all openings such as windows and doorways are closed. Moreover, when the air supplied into the room is heated indoors, the warmed air naturally rises, is naturally exhausted from the lower floors to the upper floors, and is naturally exhausted from the roof. does not require

[Problem to be solved by the invention]

A natural ventilation system that supplies air from under the floor and exhausts it from the roof is directly affected by the outside temperature. Therefore, especially in winter, the cold air under the floor is supplied directly into the room, cooling the room.

The purpose of the present invention is to perform air tA ventilation using the geothermal heat under the floor.

[Means for solving r18] An air supply port in which one end of an air supply pipe buried at a required depth underground under the floor can be opened under the floor or any ground surface to supply air, and the other end is provided on the floor surface. The underfloor geothermal heat is exchanged with the underground air supply pipe and then brought into the room.

[For production]

After exchanging heat with geothermal heat through air supply pipes buried in the basement,
The high-temperature air that is supplied into the room and heated indoors rises due to the temperature difference in the air, and is naturally exhausted from an exhaust port provided on the room side or an exhaust pipe provided on the roof. By this exhaust air, fresh air is taken into the room through the air supply pipe. At this time, geothermal heat will be utilized and natural ventilation will be provided.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS The air conditioning and ventilation system for a house according to the present invention will be explained below based on the illustrated embodiments.

In the figure, 1 is a house having the required shape and area, and although the illustrated one is a two-story house, a one-story house can also be adopted.

In this house ff1l, 19 air is ventilated from the air supply port 3 on the floor 2 through the ventilation port 4 continuously or selectively individually through the rooms R1, R2, R3...
- Exhaust the air to the outside through an exhaust port 5 provided on the ceiling 6, or through an exhaust lower or exhaust duct 8 provided on the ceiling 6, and then exhaust to the outside air from an exhaust chimney or exhaust pipe protruding from the roof 9.

In this way, the entire building 1 is supplied with air from below the floor, passes through the room, uses the temperature difference in the air, and the high temperature air inside the room rises and is sent to the outer wall 11c: the stepped exhaust port δ or the roof 9. Exhaust air is discharged from one or both of the provided exhaust chimneys 10, and ventilation is performed by natural convection.

One end of the air supply pipe 2 is connected to the air supply port 3 provided in the floor 2, and this air supply pipe 12 is buried at the required depth in the ground under the floor, and its tip is placed at an arbitrary position under the floor or outside the building m1. It is opened at an arbitrary position, and air is supplied into the pipe through this opening 13. The opening 13 of this power supply pipe 12 shall be located at a position or equipped with such equipment to prevent rainwater from entering.

Furthermore, the depth and length of the air supply pipe 12 are appropriately determined so that the air flowing through the pipe exchanges heat using geothermal heat, so that the temperature of the supply air is slightly higher than the outside temperature in winter. On the other hand, in the summer, the temperature is set to be slightly lower than the outside temperature, so that when the building is naturally ventilated, it can also be air-conditioned at the same time.

〔Effect of the invention〕

According to the present invention, one end of the air supply pipe is buried underground at a required depth under the floor and can be opened under the floor or on any ground surface to supply air, and the other end is connected to an air supply port provided on the floor. death,
Since the underground geothermal heat is exchanged through the underground air supply pipes and then brought into the room, it has the advantage of natural ventilation that uses geothermal heat to keep you warm in the winter and cool in the summer.

[Brief explanation of drawings]

The drawing shows an embodiment of the air conditioning and ventilation system for a house according to the present invention. 1 is the house, 2 is the floor, 3 is the air supply port, 5 is the exhaust port, 10 is the exhaust chimney, l 2 is the air supply pipe.

Claims (1)

[Claims] (1) In a ventilation system that takes in air from the floor and guides it into the room and exhausts it from the roof, one end of the air supply pipe is buried at the required depth underground under the floor and is opened either under the floor or on any ground surface. The other end is connected to an air supply port provided on the floor surface, and the underground geothermal heat is introduced into the room after heat exchange through the underground air supply pipe.
