Description

[Detailed description of the invention] [Industrial application field] The present invention heats and cools a room using an air conditioning unit that exchanges heat by receiving a supply of a concentrated heat medium, and also uses a ventilation fan unit. This invention relates to an air-conditioning ventilation system for apartment buildings that uses air to ventilate rooms.

[Prior art] In the case of high-rise housing complexes, air conditioning units and ventilation fan units are used for heating, cooling, and ventilation in each room, in order to ensure that the rooms are highly airtight and to prevent fires. This is now being done for each residential unit.

FIG. 2 shows this conventional example, in which each dwelling unit is equipped with an air conditioning unit 1 and a ventilation fan unit 2. And this air conditioning unit 1
The ventilation fan unit 2 is integrated and usually attached to the ceiling of a hallway, etc., and a main air supply/exhaust duct 3 extends from the ventilation fan unit 2 to the outside of the outer wall 4. On the other hand, for ventilation in the washroom, toilet, and bathroom, an independent sanitary duct 5 is extended outside the outer wall 4, and a sanitary fan 6 is attached to this sanitary duct 5.

In addition, air supply and exhaust to the kitchen is carried out through a kitchen air supply and exhaust duct 7.

In the figure, 8 is an air conditioning/ventilation duct extending from the air conditioning unit 1 into each living room, and 9 is a bathroom drying unit, which has a built-in fan for blowing hot air.

As is clear from the above explanation, in the case of conventional air conditioning ventilation equipment for apartment buildings, there are a total of five fans: one for ventilation, one for air conditioning, one for sanitary purposes, one for kitchen, and one for drying bathrooms. A total of five duct through holes are required: two for main air supply and exhaust, one for sanitary use, and two for kitchen use.

[Problems with the Prior Art] As described above, the conventional ventilation system requires a total of five fans for each residential unit, which poses problems in terms of equipment costs, space, and energy conservation.

Also, having a total of five holes penetrating the outer wall increases the number of construction restrictions due to problems with the strength of the building, and having five through holes in the outer wall 4 also poses problems with the aesthetics of the building. be.

The purpose of the present invention is to reduce the number of air conditioning and ventilation fans and the number of through holes in the outer wall in an apartment complex.

[Structure of the present invention] The present invention proposes the following ventilation device as a means for achieving the above object.

Air conditioning/ventilation ducts are extended from the air conditioning unit, which exchanges heat by supplying a centrally generated heat medium, to each room to heat and cool the room, and ventilation fan units are used to heat and cool each room. In an air-conditioning ventilation system for an apartment complex designed to provide ventilation, the air-conditioning unit and the ventilation fan unit are separated and the ventilation fan unit is installed close to the exterior wall. A sanitary duct that discharges air sucked in from the washroom, toilet, and bathroom to the outside is connected to the exhaust side of the main air supply and exhaust duct. , an air conditioning ventilation system for an apartment complex, characterized by a sensor for monitoring the usage status of the bathroom, and a controller for receiving a signal from the sensor and prioritizing exhaust air from the sanitary duct side. Device.

In the above configuration, the sanitary duct is connected to the main supply/exhaust duct and a ventilation fan is used to exhaust both sides, so if this continues, there is a risk that bad odors from the sanitary side will enter the living room.
This measure is necessary. As a means of this, the usage status on the sanitary side is monitored by detection means such as sensors, and when a usage signal is input, the rotation speed of the fan in the ventilation fan unit is increased to increase the air volume, or the main air supply and exhaust A tamper is installed on the commercial duct side where the sanitary duct is connected or upstream from this, and the opening degree of this tamper is controlled to favor the sanitary side, thereby eliminating the entry of bad odors into the living room side. You can do it like this. Note that these controls are automated by using a controller.

Next, if the bathroom is also used as a drying room, a bathroom drying duct is extended from the air conditioning unit into the bathroom.

[Operation] Fresh outside air is taken in and exhausted from the ventilation fan unit via the main supply/exhaust duct and the air conditioning unit. The air-conditioning unit of each dwelling unit is supplied with a concentrated heat medium generated via a pipe (not shown), which is sucked in from the air supply side of the main air supply and exhaust duct. The outside air exchanges heat with this air conditioning unit and is blown into the room through the air conditioning/ventilation duct for heating or cooling. Also, part of the air (circulated air) sucked from the room is circulated after undergoing reheat exchange, and the other part is exhausted via the exhaust fan unit.

Ventilation of each room is performed by operating a ventilation fan unit and an air conditioning unit, and via an air conditioning/ventilation duct. Additionally, each room is equipped with a controller, allowing users to freely control heating, cooling, ventilation, and other modes by automatically controlling heating, cooling, and ventilation.

On the sanitary side, when either the washroom, toilet, or bathroom is used, a sensor detects this and a signal is input to the controller. When the controller receives this signal, it sends a high-speed rotation signal to the ventilation fan unit. As a result, the ventilation fan unit enters high-speed rotation mode, increasing the air volume and suction volume (exhaust volume). Alternatively, the opening degree of the damper is controlled to switch to the sanitary side exhaust priority mode.

The operation of air supply and exhaust on the kitchen side is well known.

[Embodiment and its operation] FIG. 1 shows an embodiment of the present invention. Number 1 is an air conditioning unit, and this unit is attached to the ceiling of the hallway. A heat exchanger and a fan (not shown) for heating and cooling are built into the air conditioning unit 1, and a heat medium generated in a concentrated manner is passed through a circulation pipe (not shown) to this heat exchanger. ), and heats the air and circulating air taken in from the air supply side of the main air supply and exhaust duct 3 and the ventilation fan unit 2 that is installed independently on the air supply and exhaust duct 2' and the outer wall 4 side. Alternatively, it has a function of cooling and sending hot or cold air to each room via an air conditioning/ventilation duct 8 using a fan provided in the air conditioning unit 1.

Reference numeral 5 denotes a sanitary duct, and the exhaust from the washroom, toilet, and bathroom is concentrated in this duct 5, and its tip is connected to the exhaust side of the main air supply/exhaust duct 3.

7 is a kitchen air supply and exhaust duct.

Numeral 10 is a bathroom drying duct extending into the bathroom from the outlet side of the air conditioning unit 1, so that the hot air generated by the air conditioning unit 1 can be sent into the bathroom.

Reference numeral 11 denotes a controller, which performs the following control.

The operation of the air conditioning unit 1 and the ventilation fan unit 2 is controlled by receiving signals from the controller installed in each room.

For example, when heating or cooling mode is selected in any of the rooms, the fan is operated while circulating the heat medium in the air conditioning unit 1.
Furthermore, at the same time, the ventilation fan unit 2 starts operating, takes in outside air from the air supply side of the supply/exhaust duct 2', and enters the outside air into the air conditioning unit 1 via the air supply side of the main supply/exhaust duct 3. Send it in. The outside air is heat exchanged with the heat exchanger in the air conditioning unit 1,
The hot air or cold air is sent out from the air conditioning/ventilation duct 8 into each room. In addition, the hot or cold air sent into each room from the air conditioning/ventilation duct 8 can be controlled so that some or all of the circulating air is mixed with the outside air taken in as described above, or it can be controlled so that it does not mix at all. It is.

Next, when the ventilation mode is selected in each room, the ventilation fan unit 2 is operated, and only the outside air is air-conditioned and ventilated by operating the fan without passing the heat medium through the heat exchanger in the air-conditioning unit 1. duct 8
It is sent indoors via. Exhaust air from each room is collected into the air conditioning unit 1 via the exhaust space, and then flows from the exhaust side of the main supply/exhaust duct 3 to the ventilation fan unit 2 and the exhaust side of the supply/exhaust duct 2'. released outside.

Next, when use is detected in the washroom, toilet, or bathroom, the ventilation fan unit 2 is operated in response to the signal, and at this time, if heating/cooling or ventilation is being performed in each room, If so, either switch the operation to increase the air volume of the ventilation fan unit 2, or send a signal to the valve 12 attached to the exhaust side of the main air supply/exhaust duct 3 as shown in Figure 1, and change the opening degree of this valve 12. Prioritizes the exhaust from the sanitary side and controls the odor so that it does not reach each room. However, when no heating/cooling or ventilation is performed in each room, the valve 12 can be completely closed.

Next, when a bathroom drying signal is input, the air conditioning unit 1 and the ventilation fan unit 2 are operated. However, when heating is in progress, a damper (not shown) is opened to allow hot air to flow to the bathroom drying duct 10, and when cooling is in progress, an auxiliary heater or heat exchanger (not shown) is opened. (not shown). Ventilation in the bathroom during bathroom drying is performed via the sanitary duct 5.

Note that the above example is only a part of the functions of the controller 11, and other functions and operation modes can of course be added at will.

[Effects of the present invention] As described above, in the present invention, the air conditioning unit and the ventilation fan unit are separated, and ventilation on the sanitary side is performed via the ventilation fan unit.

As a result, there is no longer a need for a ventilation fan on the sanitary side, which was previously required, and there is no longer a need to provide a through hole for a duct on the sanitary side in the outer wall.

Next, when drying the bathroom, the hot air for drying the bathroom is sent from the air conditioning unit, so there is no longer a need to install a separate bathroom dryer in the bathroom.

Therefore, according to the present invention, a sanitary fan and a through hole are omitted, and a bathroom drying fan is also omitted. As a result, in air conditioning ventilation systems for apartment buildings, the number of fans has been reduced from 5 to 3, and the number of through holes has been reduced from 5 to 4.
It is possible to reduce equipment costs and operating costs, improve the appearance of the building, and reduce obstacles to the strength of the building, which has the effect of expanding the range of implementation.
