BEST MODE FOR CARRYING OUT THE INVENTION Embodiment 1. Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a conceptual diagram showing a ventilation air conditioning system of the present invention.
D is an independent room, each of which is partitioned by a wall, etc.
Is an air conditioner that is an air conditioner installed in room A,
Reference numeral 2a denotes an air supply device that is provided in the room A and supplies the outdoor air to the room A. Reference numeral 3a denotes an exhaust device that is provided in the room B and exhausts the indoor air of the room B to the outside.

Reference numeral 4a denotes an air passage member for connecting the room A and C to each other, 4b denotes an air passage member for connecting the room C and D, and 4c connects the room D and room B. In the air passage member, the room A and the room B are in communication with each other by these air passage members 4a to 4c. Further, the air conditioner 1 and the air supply device 2a are arranged close to each other, and the air passage member 4a is arranged in a symmetrical position in the room of the air conditioner 1 and the air supply device 2a.

Next, the operation will be described. Air supply device 2a
When air is supplied from outside the room, the air in the room A is pressurized. Further, when the air in the room is exhausted to the outside by the exhaust device 3a, the air in the room B is decompressed. As a result, an air pressure difference is generated between the room A and the room B. For example, 100 m3 from the air supply device 2a
/ Hr of air is supplied to the room A, and 100 m3 / hr of air is exhausted from the room B of the exhaust device 3a, the volumes of the rooms A, B, C, and D are 30 m3, A,
Natural ventilation frequency of each room of B, C, D is 0.5 times / hr
And

At this time, in the room A, 100 m3 / hr of air is supplied from the air supply device 2a, and 30 × 0.5 =
The air of 15 m3 / hr is naturally exhausted, and the air in the room A heated and cooled by the air conditioner 1 is 100−15 = 85.
m3 / hr is sent to the room of C through the air passage member 4a. In the room of C, 85m3 / hr is sent from the room of A through the air passage member 4a, the air of 15m3 / hr is naturally exhausted, and the air of 85-15 = 70m3 / hr is passed through the air passage member 4b. Sent to room D.

In the room of D, 70 m3 / hr of air is sent from the room of C through the air passage member 4b, and the air of 15 m3 / h
The air of r is naturally supplied, and 70 + 15 = 85m3 / h
The air of r is sent to the room of B through the air passage member 4c.
In the room B, 85 m3 / hr of air is sent from the room of D through the air passage member 4c, the air of 15 m3 / hr is naturally supplied, and the air of 85 + 15 = 100 m3 / hr is discharged from the exhaust device 3a to the outside of the room. Exhausted to.

According to the above construction, the room A and the room B are
Using the pressure difference from the room A, the fresh air supplied in the room A by the air supply device 2a is conditioned by the air conditioner 1 provided in the room A, and the fresh air is conditioned. The air velocity can be evenly sent to each of the rooms B, C, and D without a large difference in the air volume, and efficient ventilation and air conditioning of the entire building can be performed without using duct piping. Therefore, it is possible to construct a ventilation and air-conditioning system for the entire building even in the case of a conventional house or the like where the duct piping is difficult or the space above the ceiling cannot be secured, and since there is no duct piping, it can be realized at low cost.

In the above embodiment, the exhaust device 3a is provided in the room B, and the room A is communicated with the air passage members 4a to 4c so that the room A is upstream and the room B is downstream. However, even if the room A provided with the air supply device is provided with the air conditioner and each room is communicated with the air passage member and the exhaust is performed by natural exhaust, the room A of the room is provided by the air supply device. Since the pressure is high, the pressure distribution is A
It is possible to supply the fresh and conditioned air taken in the room A to the rooms in the building by gradually lowering from the room A to the room B.

Further, when there is a room in the building where ventilation or air conditioning is not particularly required, it does not have to be incorporated in the room communicating with the air passage member from the room A to the room B. In the above-described embodiment, in order to perform the most efficient ventilation and air conditioning, the system is configured such that the room B equipped with the exhaust device 3a is located at the most downstream side of the room communicated by the air passage member. Therefore, if the exhaust device is provided in, for example, the room A, and each room is communicated with the air passage member, and the air supply amount of the air supply device is made larger than the exhaust amount of the exhaust device, the pressure of the room A becomes high. Therefore, the room B does not have an exhaust device, and even if the room is naturally exhausted, efficient ventilation and air conditioning can be performed to some extent. In this case, since the air is exhausted in the room A, more fresh air is transferred to each room, and the air in the room B, which is the most downstream, is less polluted.

If there is a room in which ventilation / air conditioning is particularly required and a room in which the ventilation / air conditioning system is desired to be installed for the time being, one of the rooms in which ventilation / air conditioning is particularly required is designated as room A and the other ventilation is performed. The room that requires special air conditioning is designated as room B, and the rooms from room A to room B are connected by air passage members so as to relay each room where ventilation and air conditioning are particularly necessary, and the room for air supply to room B is supplied by the air supply device. By providing an exhaust device with a smaller exhaust air volume than the air volume and performing ventilation air conditioning by the pressure difference, by connecting the room that you want to incorporate into the ventilation air conditioning system for the time being with the room where ventilation air conditioning is particularly necessary by the air passage member,
For the time being, it is also possible to supply fresh, conditioned air at the level of natural exhaust to the rooms that are to be incorporated into the ventilation air conditioning system.

Embodiment 2. FIG. 2 is a conceptual diagram showing a ventilation air-conditioning system according to another embodiment. In the figure, the configurations from 1 to 4 are the same as those of the first embodiment, and the description thereof will be omitted. Reference numeral 5a denotes a heat exchange device provided between the room A and the room B, which is an air supply device 2a for supplying air from the outside to the room A and an exhaust device for discharging indoor air from the room B to the outside. Heat exchange between the air supply by the air supply device 2a and the exhaust air by the exhaust device 3a is performed with the air supply device 3a.

Next, the operation will be described. Since the operation from the supply of the outdoor air to the room A by the air supply device 2a to the exhaust device 3a is the same as that of the first embodiment,
The description is omitted. A feature of the present embodiment is that heat is exchanged between the air supply by the air supply device 2a and the exhaust air by the exhaust device 3a, whereby the indoor air and the outdoor air that are ventilated and air-conditioned are exchanged. Since heat exchange is performed in the air conditioner, air conditioning loss such as cooling and heating is reduced, and efficient ventilation and air conditioning of the entire building can be performed.

Embodiment 3. FIG. 3 is a conceptual diagram showing a ventilation air-conditioning system according to another embodiment. In the figure, the configurations from 1 to 4 are the same as those of the first embodiment, and the description thereof will be omitted. Reference numeral 6a denotes a circulation device that connects the room B and the room A and has a blowing unit that blows indoor air from the room B to the room A. The circulation device 6a allows the room B and the room A to communicate with each other. And the indoor air circulates.

Next, the operation will be described. Since the operation from the outdoor air being supplied to the room A by the air supply device 2a to the outdoor air being exhausted by the exhaust device 3a is the same as that of the first embodiment, the description thereof will be omitted.

A feature of this embodiment is that the circulation device 6a forms an air flow from the room B to the room A, so that the transfer of air between the rooms is accelerated and the air flow is increased. However, not only the straight flow that the air supply by the air supply device 2a is exhausted by the exhaust device 3a, but also a part of the air-conditioned air passes from the room B through the circulation device 6a to the air in the room A again. The harmonized circulation allows for quick air conditioning of the rooms combined by the ventilation air conditioning system. The system according to the present embodiment is very effective in such a case where a large space as a whole is ventilated and air-conditioned.

Fourth Embodiment FIG. 4 is a conceptual diagram showing a ventilation air conditioning system according to another embodiment. In the figure, the configurations 1 to 5 are the same as those in the second embodiment, and 6
The configuration is the same as that of the third embodiment, and the description thereof is omitted. A characteristic of the present embodiment is that the air supply device 2
The point is that heat is exchanged between the air supply by a and the exhaust by the exhaust device 3a, and an air flow is formed from the room B provided with the exhaust device 3a to the room A by the circulation device 6a.

As a result, heat exchange is performed between the indoor air that has been ventilated and air-conditioned and the outdoor air, air conditioning loss such as cooling and heating can be reduced, and efficient ventilation and air conditioning of the entire building can be performed.
Also, the transfer of air between rooms is accelerated, and the flow of air is
Not only the straight flow that the air supply by the air supply device 2a is exhausted by the exhaust device 3a, but also a part of the air-conditioned air is air-conditioned again in the room A through the circulation device 6a from the room B. Because it circulates, the rooms combined by the ventilation air conditioning system can be quickly conditioned.

The circulation device does not necessarily have to use the room B as the end room of the air flow as in the present embodiment, but in particular, as in the present embodiment, the room B is the most distant from the room A. If the room is located downstream and the ventilation and air conditioning are the slowest, in the initial stage of the ventilation air conditioning operation, the air circulating between the rooms by the circulation device 6a has a large temperature difference from room B to room A. Since the heat exchange device 5a efficiently recovers heat from the air exhausted by the exhaust device as it is guided to the room and air-conditioned, it is recommended to promote efficient air conditioning in the terminal room. Become.

Embodiment 5. FIG. 5 is a system configuration diagram showing a ventilation air-conditioning system according to another embodiment. In the figure, A to E and the kitchen, toilet, washroom, and bathroom are independent rooms each partitioned by a wall or the like. Is an air conditioner provided in the room A, 2a is provided in the room A, and an air supply device for supplying the outdoor air to the room A is provided in the room B 3a is provided in the room B. Exhaust device for exhausting air to the outside, 5a is a heat exchange device provided between the room A and the room B, and 6a communicates the room B and the room A, from the room B to the room A A circulation device having a blowing means for blowing air, each of which has the same configuration as that of the fourth embodiment.
Are the same as those of the same reference numeral.

Reference numeral 4a denotes an air passage member for connecting the room A and C to each other, 4b denotes an air passage member for connecting the room C and D, and 4c connects the room D and E. Air duct member,
Reference numeral 4d denotes an air passage member that connects the room E and the room B, and the room A and the room B are in communication by the air path members 4a to 4d. In addition, the air conditioner 1 and the air supply device 2
a is arranged close to each other, and the air passage member 4a is arranged in a symmetrical position in the room of the air conditioner 1 and the air supply device 2a and A. Similarly, the air passage members 4a and 4 in each room
b, 4b and 4c, 4c and 4d are also arranged at symmetrical positions.

3b is an individual exhaust device provided in the bathroom for exhausting the air in the bathroom to the outside, and 3c is an individual exhaust device provided in the washroom for exhausting the air in the washroom to the outside,
3d is an individual exhaust device that is installed in the toilet and exhausts the air in the toilet to the outside of the room. 3e is an individual exhaust device that is installed in the kitchen and exhausts the air in the kitchen to the outside of the room. Also, 4
e is an individual air passage member connecting the room B and the washroom, 4f
Is an individual air passage member for connecting the bathroom and the bathroom, 4g is an individual air passage member for connecting the room B and the toilet, and 4h is an individual air passage member for connecting the room B and the kitchen.

Next, the operation will be described. The outdoor air is supplied to the room by the air supply device 2a, and the operation until the room B is exhausted by the exhaust device 3a and the heat exchange operation by the heat exchange device 5a, the indoor air by the circulation device 6a The operation to circulate is the same as that of the fourth embodiment, and the description thereof will be omitted.

Now, when the washroom is in use and the individual exhaust device 3c is operated, the air ventilated and air-conditioned in the room A moves to the room B due to the pressure difference, and the room air in the room B is changed. A part is supplied to the washroom via the air duct member 4e.
This allows the washroom to be ventilated and air conditioned. Unlike ordinary rooms, the washroom does not require constant ventilation. If this washroom is incorporated into the series of flow from room A to room B, it will always enter the operating state of the ventilation air conditioning system.

If a separate flow is created as in the present embodiment, the ventilation and air conditioning can be performed only when the bathroom is used, and the system from the room A to the room B can be downsized. It is possible to quickly perform ventilation and air conditioning from room B to room B, which is efficient. Moreover, since the washroom is usually a small space, even if the ventilation air conditioning is performed only during use, the ventilation air conditioning can be immediately performed to prepare the environment.

Next, when the toilet is in use and the individual exhaust device 3d is operated, the air ventilated and air-conditioned in the room A moves to the room B due to the pressure difference, and one of the indoor air in the room B is The parts are supplied to the toilet via the air passage member 4g.
As a result, the toilet can be ventilated and air-conditioned. Unlike a normal room, the toilet does not need to be constantly ventilated and air conditioned, like a toilet. Therefore, the system from room A to room B can be downsized by ventilating and air-conditioning only when using the toilet without incorporating it in the series of flow from room A to room B. Ventilation and air conditioning of room B can be performed quickly from room to room B, which is efficient.

Further, since the washroom is usually a small space, even if the ventilation air conditioning is performed only during use, the ventilation air conditioning can be immediately performed to prepare the environment. Moreover, since the air in the toilet is unpleasant to mix with the air in other rooms from the point of odor, it is desirable that it be at the end of the air flow, and is circulated through a heat exchanger or a circulation device. It is desired to be exhausted as it is. According to this embodiment,
The air in the rooms A to E is heat-exchanged and circulated so that the air can be quickly ventilated and air-conditioned, and as a result, the room such as a toilet can be efficiently ventilated and air-conditioned.

Next, a case where the bathroom is in use will be described. When the bathroom is used, the bathroom is usually used for undressing, and the bathroom is used to enter and leave the bathroom. Therefore, the usage of the bathroom is equal to the usage of the bathroom and the bathroom. When the bathroom is in use and the individual exhaust devices 3c and 3b are operated at the same time, the air ventilated and air-conditioned in the room A moves to the room B due to the pressure difference, and a part of the room air in the room B partially It is supplied to the washroom via the air duct member 4e. Further, a part of the room air in the washroom is supplied to the washroom via the air passage member 4f.

This makes it possible to ventilate and air-condition the bathroom and the washroom that are used at the same time when the bathroom is used. Thus, unlike a normal room, the bathroom does not require constant ventilation and air conditioning. If this bathroom is incorporated into a series of flows from the room A to the room B, it will always enter the operating state of the ventilation air conditioning system. If a separate flow is created as in this embodiment, ventilation and air conditioning can be performed only when the bathroom is in use, and the system from room A to room B can be made small. Ventilation and air conditioning of the room can be done quickly and it is efficient.

Further, since the bathroom and the washroom are usually small spaces, even if the ventilation and air conditioning are performed only during use, the ventilation and air conditioning can be immediately performed to prepare the environment. In addition, since the humidity of the bathroom becomes high when used, it is desirable to mix it with the air in other rooms, so it is desirable to be at the end of the air flow, and it is circulated through a heat exchanger or a circulation device. It is desired to be exhausted as it is. According to the present embodiment, the air in the rooms A to E is heat-exchanged and circulated, and the ventilation and air conditioning can be quickly performed. As a result, the bathroom can also be efficiently ventilated and air-conditioned.

According to this control method, the degree of ventilation and air conditioning for each room can be adjusted by appropriately controlling the opening of the damper, and the air passage can be closed by closing the damper to perform ventilation and air conditioning. Since unnecessary rooms can be excluded from the system, airtightness is improved, and ventilation and air conditioning of the entire building can be efficiently performed. Similarly to the case of the room D, by adjusting the opening degree of the damper corresponding to each of the other rooms, the rapid ventilation and the rapid air conditioning of each room can be efficiently performed, and the rapid ventilation and the rapid ventilation are performed. Ventilation and air conditioning can be performed at least in a room that is not air-conditioned, and ventilation and air conditioning of the entire building can be performed efficiently.
