Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a residential ventilation system for ventilating a room in a house.

[0002]

2. Description of the Related Art Conventionally, in a general-purpose house, an appropriate amount of ventilation has been obtained through a gap between fittings. However, in recent years, in detached houses and condominiums such as condominiums, airtightness of rooms tends to be improved in order to improve air-conditioning efficiency.

As a result of the improved airtightness, there has been a problem that the air permeability of each room in the house is deteriorated, and mold is liable to be generated due to dew condensation or the like generated on the window glass and walls.

Therefore, there is an air conditioning system in which a duct is provided in each room and the air is adjusted by this duct. However, this air conditioning system is suitable for use in large-scale buildings such as buildings in which one floor is almost in communication, but in single-family houses and condominiums such as condominiums, individual devices must be provided. However, there was a problem that the cost increased.

For this reason, the ventilation method described in Japanese Patent Laid-Open No. 3-199841 is adopted.

That is, a forced exhaust port for forcibly exhausting air is provided at the entrance of a house or an apartment. Further, each room is provided with a natural air supply port for flowing outside air into the room and a ventilation port for flowing air inside the room.

Further, a ventilation flow passage is formed in which the air from the natural air supply port is made to flow into the room and the air in the room is made to flow through the ventilation port to the forced exhaust port.

[0008]

However, in such a conventional ventilation structure, cold air (cold draft) is given to a person in the vicinity of the natural air supply port because the outside air taken in from the natural air supply port is cold during heating. It gives a feeling of discomfort.

Further, since there is only one forced exhaust port, if the exhaust amount of forced exhaust is increased, the pressure difference between the room in which the forced exhaust port is provided and the other rooms becomes large, making it difficult to open and close the door. There was also a problem that there was a wind noise, depending on the amount of air passing through the gap between the fittings.

In order to eliminate this pressure difference, it is conceivable to increase the opening area of the intake port, but in this method, when the wind is strong, it is easily affected by the outside air, and moreover, the cold air (cold draft) is generated. The problem increases.

The problem of this pressure difference can be understood to some extent at the time of construction planning. Therefore, in a room far from the forced exhaust port, it is possible to increase the opening area of the ventilation port to reduce the ventilation resistance. Depends on the fitting position,
In recent years, if the floor plan is changed due to reform or the like performed, it cannot be dealt with.

Moreover, the ventilation amount required for each room varies depending on the presence or absence of people and the presence or absence of pollutants (water vapor, smoke, carbon monoxide, etc.) in the room. It is not possible to control the amount of ventilation for each room, and even a room that does not require ventilation is uniquely ventilated. For this reason,
As the cooling and heating efficiency decreases, the amount of electric power for operating the forced exhaust port increases. Also, exhaust noise is large,
There was also a problem that it hindered a good night's sleep at night.

Therefore, according to the present invention, regardless of the outside air condition,
A house where the outside air can be comfortably introduced, the pressure difference between the rooms can be reduced, the necessary ventilation can be provided for each room, and the construction cost and running cost can be suppressed and noise can be reduced. It is an object to provide a ventilation system for a vehicle.

[0014]

In order to achieve the above object, according to the first aspect of the present invention, an air conditioner having a forced outside air intake function is provided at the outside air intake of each room of a house, and A ventilator for forced exhaust is provided that forms a vent for ventilating between rooms and is provided in a vent that communicates the inside and outside of the house, and forcibly exhausts the air in each room to the outside of the house through the vent. The provided ventilation system for a house is characterized in that the ventilation system for a house has a control means for making the amount of outside air introduced into the room by the air conditioner approximately equal to the amount of exhaust air exhausted by the forced exhaust fan.

According to a second aspect of the present invention, the control means includes a contaminated atmosphere sensor in each room,
The ventilation system for a house is characterized by detecting the polluted atmosphere with the polluted atmosphere sensor and controlling the air conditioner in each room to operate.

[0016]

[Operation] According to the first aspect of the present invention having such a configuration, the control unit exhausts the amount of outside air introduced into the room by the air conditioner provided in each room by the forced exhaust ventilation fan. Is almost the same as.

Therefore, the pressure difference between the rooms can be eliminated.

Further, since the outside air is introduced after the temperature, humidity, air volume, etc. are adjusted by the air conditioner provided in each room, each room should have a comfortable atmosphere regardless of the state of the outside air. Can be done.

Moreover, since it is only necessary to exhaust the amount of outside air introduced into the room by the forced exhaust ventilation fan, the operating amount of the forced exhaust ventilation fan can be varied as necessary to suppress running costs and reduce noise. It can be reduced.

According to the second aspect of the present invention, the control means detects the polluted atmosphere by each polluted atmosphere sensor provided in each room and operates each air conditioner in each room. To control.

For this reason, since only the room in which the pollution has occurred is ventilated, the cooling and heating efficiency is good, and the exhaust air volume of the forced exhaust fan is only the amount required for the room having the contaminated atmosphere. Moreover, running costs can be suppressed and noise can be reduced.
