Abstract

PROBLEM TO BE SOLVED: To perform reliable ventilation of the whole of a house by a minimum ventilation amount without the occurrence of uncomfortable cold draft. SOLUTION: A second story hall 12 ventilated by a ventilation fan 42 for exhaust and a ventilation fan 46 for air supply is built in a housing 10, and the second story hall 12 is full up with fresh indoor air. By ventilating a living room 16 with air in the second story hall 12 by a ventilation fan 20, air in the living room 16 is replaced with fresh air. By taking air in the second story hall 12, having temperature reaching an indoor temperature, without directly taking outdoor air in the living room 16, uncomfortable cold draft is not generated and a difference in atmospheric pressure between living rooms is prevented from generating.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a ventilation method for a house.

[0002]

2. Description of the Related Art As shown in FIG. 2, as a conventional residential ventilation method, an air conditioner 58 with a forced outside air supply function is provided in each of the living rooms 50, 52, 54, and a ventilation fan 60 for forced exhaust is provided in a kitchen 56. There is an installation in which a living room and a kitchen 56 are communicated through a vent 62 (see JP-A-7-305874).

[0003] In this ventilation method, the amount of air supplied by the air conditioner 58 with a forced outside air supply function is made equal to the amount of exhaust air exhausted by the ventilation fan 60 for forced exhaust, thereby reducing the pressure difference between each room. To eliminate variations in ventilation capacity between rooms.

Incidentally, an air conditioner 58 with a forced outside air supply function is provided.
Although the temperature of the outside air to be supplied can be adjusted to some extent, since the outside air temperature is low in winter, an unpleasant cold draft (cool air) is likely to be generated around the air supply port.

[0005] In the conventional ventilation method, the ventilation volume of each room is determined by the assumed number of users in each room. For example, 1
When the required amount of ventilation per a 20 m ³ / h, left room 54 (living) Since use with four 80 m ³ /
h, the middle room 52 (bedroom) is used by two people, so 4
0 m ³ / h, the living room 50 (child room) on the right side is 40 m ³ / h because it is used by two people, and the total ventilation volume of the entire house is:
120 m ³ / h.

[0006] That is, although four people actually live, ventilation for eight people is performed, and a great amount of energy is lost. However, no ventilation method has been found that has improved such problems.

[0007]

SUMMARY OF THE INVENTION In view of the above fact, it is an object of the present invention to reliably perform ventilation of an entire house without generating an unpleasant cold draft and with a minimum ventilation volume.

[0008]

According to the first aspect of the present invention, a core space ventilated by outdoor air is provided in a house, and the core space is filled with fresh air. The air in the living room is replaced with fresh air by ventilating each living room with the air in the core space.

As described above, by not taking in the outdoor air directly into the living room, but taking in the air in the core space approaching the room temperature into the living room, unpleasant cold draft does not occur and there is no pressure difference between the living rooms. .

[0010] According to the second aspect of the present invention, the temperature of the core space further approaches the living room temperature by the heat exchange ventilation, so that the temperature difference in the house can be suppressed.

According to the third aspect of the present invention, the ventilation amount of the core space is set based on the number of residents of the house. In other words, there is no energy loss because the ventilation volume is not the sum of the ventilation volume calculated by the total number of assumed users for each room but the ventilation volume optimized for the resident. In addition, the entire house can be required and sufficiently ventilated by this ventilation amount.

According to the invention described in claim 4, the core space is:
It is a sanitary zone, corridor, or staircase hall. For this reason, moisture, odor, etc. in the sanitary zone are exhausted to the outside intensively. In addition, the corridor and staircase hall adjacent to the living room are used as the core space, so that the living room can be smoothly ventilated.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a floor plan of a first floor of a house 10 using a ventilation method for a house according to the present embodiment.

At the center of the house 10, a staircase hall 12 is provided as a core space. On the left side of the staircase hall 12, there is a living room 16 partitioned by a partition wall 14.
Is provided. The partition wall 14 is provided with an access door 18 and a ventilation fan 20.

A bedroom 28 and a children's room 30 are formed on the right side of the staircase hall 12 by partition walls 22, 24 and 26. An entrance door 32 and a ventilation fan 34 are provided on the partition wall 22 of the bedroom 28, and an entrance door 36 and a ventilation fan 38 are also provided on the partition wall 26 of the child room 30.

On the other hand, on the outer wall 40 of the staircase hall 12, an exhaust ventilation fan 42 is provided, and on the outer wall 44, an air supply ventilation fan 4 is provided.
6, the outdoor air supplied by the air supply ventilation fan 46 blows through the stair hole 12, and the exhaust ventilation fan 42 is provided.
It is designed to be exhausted from outside.

Next, the operation of the residential ventilation method according to this embodiment will be described. As shown in FIG. 1, when the exhaust ventilation fan 42 and the air supply ventilation fan 46 are driven, fresh outdoor air is taken into the staircase hall 12. Here, the ventilation fan 20,
Driving 34, 38 replaces the dirty air in each room with fresh air in staircase hall 12.

As described above, the outdoor air is not directly taken into the room, but the staircase hole 12 approaching the room temperature is taken indirectly, so that unpleasant cold draft does not occur and there is no pressure difference between the rooms.

The required ventilation volume of the staircase hall 12 is set based on the number of residents of the house 10. That is, the number of people in the living room 16 is four, the number of people in the bedroom 28 is two, and the number of people in the children's room 30 is two. It is determined. This required ventilation amount is a ventilation amount at which the exhaust fan 42 constantly ventilates.

The required ventilation volume per person is 20 m
When ³ / h, it is necessary ventilation 4 people ^{× 20m 3 / h = 80m 3} / h. This allows necessary and sufficient ventilation of the entire house without losing energy as in the related art.

In the present embodiment, the core space is the staircase hole 12, but a sanitary zone such as a toilet or a bathroom may be added as the core space. As a result, moisture, odor, etc. are exhausted to the outdoors intensively. In addition, by making the corridor and stair hall adjacent to the room a core space, the room can be ventilated smoothly.

As a further developed example, the exhaust path of the exhaust ventilation fan 42 and the air supply path of the air supply ventilation fan 46 may intersect, and a heat exchanger may be installed there. As a result, not only the heat loss can be further suppressed, but also the capital investment can be suppressed as compared with the case where the devices are distributed.

The air supply to the staircase hall 12 may be replaced by forced air supply by the air supply ventilation fan 46, and may be natural air supply by simply providing an air supply port or a gap in the outer wall 44. Furthermore, the ventilation volume between each room and the staircase hall 12 is determined by the number of persons actually using the room.

That is, for example, if there are two persons in the bedroom 28, the ventilation fan 34 is driven such that the required ventilation volume is 2 persons × 20 m ³ / h = 40 m ³ / h.

In this embodiment, the ventilation fans 18, 34, 3
8 and exhaust air from the undercuts (gap around the doors) of the doors 18, 32 and 36.
Air may be supplied by a ventilation fan and exhausted from the undercut. Further, the ventilation fan may be a door ventilation fan mounted on a door.

[0026]

Since the present invention has the above-described structure, the entire house can be reliably ventilated with a minimum amount of ventilation without generating an unpleasant cold draft, and energy can be saved. You can also.
