Abstract

PURPOSE:To provide an indoor ventilation method of which installing expenditure and maintenance expenditure are less expensive and a silent ventilation of an entire room can always be carried out and further it may be operated even under no air condition by a method wherein more than two ventilation ports having a heating source are attached to a slant or vertical aeration circuit. CONSTITUTION:Ventilation ports A with a heating source are constructed such that a heating source 2 such as heater and the like is set at a slant aeration circuit 1. So, when surrounding cold air enters a room 4 through ventilation ports having a heating source, the air is heated and thus an interior temperature is not decreased. An aeration circuit 1 at the ventilation port A having a heating source at the lower part of the room 4 ascends from outside toward an interior of the room. Due to this arrangement, surrounding atmosphere is taken into the indoor area through heat of the heating source 2 and then ascending air flow is generated. In turn, the aeration circuit 11 for the ventilation port A having a heating source attached to the upper part of the room 4 ascends from an interior side to the outside part. Due to this fact, indoor air is discharged due to heat of the heating source 2 and then the ascending air flow discharged out of the room is generated. Thus, in case of no air, an air flow indicated by an arrow is generated and ventilation of the interior area is carried out.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application This invention relates to an indoor ventilation method that does not reduce the temperature of the room.

(B) Prior Art Conventionally, a heat exchange type ventilation fan was used to ventilate a room without lowering its temperature, but it had the following drawbacks.

■ The fan is noisy.

■ Ventilation throughout the room is insufficient because air is supplied and exhausted from one place.

■ Equipment costs are high.

■ If you ventilate for 24 hours, maintenance costs such as electricity costs will be high.

■ It becomes large and tends to spoil the aesthetics of the room.

Also, in patent application no. 82-139449.

An air supply with a heat source is presented. According to the content, air supply and exhaust vents are installed in the room, and a heat source is attached only to the air supply vents to warm the cold outside air that enters the room and prevent the indoor temperature from dropping, but nothing has been devised for the exhaust vents. However, there have been proposals to install check valves to prevent backflow.
In that case, indoor ventilation will be stopped and depending on the wind direction, ventilation may become insufficient.

Moreover, when there is no wind, the function becomes even more inadequate.

(C) Problems to be Solved by the Invention The present invention solves the above-mentioned drawbacks and provides indoor ventilation that is low in equipment and maintenance costs, allows constant ventilation of the entire room without making noise, and works even in windless conditions. The present invention provides a method.

(D) Means to solve the problem Let me explain how to solve this problem by following the drawings.

The ventilation opening A with a heat source shown in FIG. 1 has a heat source 2 such as a heater set in an oblique ventilation circuit 1.

In the ventilation opening B-C with a heat source shown in FIG. 2, a heat source 2 such as a heater is set in a vertical ventilation circuit 3.

Therefore, when the outside cold air enters the room 4 through the ventilation opening with a heat source, it is warmed and the indoor temperature does not drop.

Each embodiment will be described according to the drawings.

FIG. 3 shows an example in which a ventilation opening A with a heat source is installed, and the ventilation circuit 1 of the ventilation opening A with a heat source at the bottom of the room 4 ascends from the outside to the indoor side. Therefore, the heat of the heat source 2 causes an updraft in which outside air is taken into the room. On the other hand, the ventilation circuit 1 of the ventilation port A with a heat source attached to the upper part of the room 4 extends from the inside of the room to the outside. Therefore, the heat of the heat source 2 causes an upward airflow in which the air inside the room is discharged to the outside.

Therefore, when there is no wind, air flows like an arrow and the room is ventilated.

At this time, the room temperature does not drop.

FIG. 4 shows an example in which a ventilation opening B with a heat source is installed, and the main body is housed within a wall 5.

FIG. 5 shows an example of a ventilation opening C with a heat source attached, and the main body is attached to the wall on the indoor side.

In FIG. 6, the main body is attached to the outside wall of the ventilation port C with a heat source.

Both are set up so that air is supplied from the bottom of the room and exhausted from the top.

Each arrow indicates the flow of air in a calm state, but when there is wind, air is supplied from the positive pressure side and exhausted from the negative pressure side, but since each ventilation port has a heat source 2, the air is not supplied. The cold air outside is warmed and the indoor temperature does not drop.

In addition, the room is constantly ventilated because there is no check valve or other restriction on supply and exhaust. Because the room is constantly ventilated,
Since the size of each ventilation opening is small, it does not require much energy from the heat source, resulting in energy savings.

Furthermore, since only a small heat source, such as a heater, is installed in a ventilation opening with a small opening, the cost is low.

(E) Effects of the Invention As described above, the present invention provides an indoor ventilation method that can constantly ventilate the entire room without noise, with low equipment and maintenance costs, whether there is wind or not.

(F) Other EmbodimentsAlthough not shown in the drawings, A type, B type, and C type may be freely combined.

Only the upper part or only the lower part can be used, and the combination of supply and exhaust directions is also free.

Furthermore, it does not depend on the type of heat source.
