In particular, the present invention relates to an air conditioning system for treating outside air for performing air conditioning in a building to which a large amount of outside air needs to be introduced, a place with a large entrance and a lot of people coming and going, and the like.

[0002]

2. Description of the Related Art In general, air-conditioning equipment such as a building is mainly equipped with equipment mainly in a dedicated machine room (air-conditioning room) because the equipment becomes large in size. Ducts are laid from the machine room to each room. Cool air or warm air obtained by air-conditioning the outside air circulated or taken in from an air conditioner is supplied to each room through a duct.

However, in recent years, from the viewpoint of space saving that a machine room is not required, and realization of comfort by introducing outside air having a temperature close to room temperature after being heated or cooled, external air processing air conditioning equipment has been developed. Widespread.

[0004] With regard to this type of air conditioner for treating outside air,
For example, there is JP-A-1-988841. This configuration will be described below with reference to the front view of FIG. 5 and the front view of FIG. 6 showing the state of installation in a building.

[0005] As shown in FIGS. 5 and 6, an outdoor-side suction port 32 and an outdoor-side air outlet 33 are provided at one end of a main body 31 constituting a housing, and an indoor-side suction port 34 is provided at an opposite end surface. And an indoor outlet 35 are provided. Most of the outer peripheral surface of the main body 31 is covered with the heat insulating layer 36.

Further, an air supply filter 37 is provided inside the main body 31 so as to communicate with the outdoor suction port 32.
Total heat exchanger 38, air supply fan 3 in order of outdoor air flow
9. Each of the air conditioning heat exchangers 40 is installed. Also,
An exhaust filter 41 and an exhaust fan 42 are provided in the order of the flow of the indoor air. In addition, a partition wall 43 is provided to separate the installation space of the air supply fan 39 and the air conditioning heat exchanger 40 from the upper space, and a portion of the partition wall 43 that contacts the total heat exchanger 38 has a circulation opening. A damper 45 is provided so as to open and close the circulation opening 44.

As shown in FIG. 6, the main body 31 is generally installed at the back of a ceiling 46a of a building 46, and an outdoor suction duct 47 is connected to the outdoor suction port 32.
7 is connected to an outdoor opening 48 communicating with the outside air.
Similarly, an outdoor air outlet duct 49 is connected to the outdoor air outlet 33, and the outdoor air outlet duct 49 is connected to an outdoor opening 50 communicating with the outside air. Further, the indoor side suction port 34
Is connected to an indoor suction duct 51, and the indoor suction duct 51 is connected to an indoor suction port 52 provided in a ceiling 46b. An indoor outlet 54 is provided on the ceiling 46b, and the indoor outlet 54 and the indoor outlet 3 are provided.
5 is connected to the indoor outlet duct 53.

In the above configuration, floating dust 55 (FIG. 2)
(Shown in FIG. 2) is introduced into the main body 31 through the outdoor suction duct 47 by the negative pressure of the air supply fan 39. Further, after the floating dust 55 is removed by the air supply filter 37, the airborne heat exchanger 40 cools or heats the air to near the temperature of the indoor air, and then blows out the room through the indoor air outlet duct 53.
The indoor air is supplied to the main body 31 by the exhaust fan 42.
When a negative pressure is formed inside, the air is introduced into the main body 31 through the indoor suction duct 51 and exhausted to the outside (outdoor).

The heat exchange between the air supply and the exhaust is performed by a total heat exchanger 38 installed at the intersection of the air supply passage 56 and the exhaust passage 57 in the main body 31. Further, the main body 31
When the damper 45 is in the open state, a part of the room air introduced into the inside of the room passes through the circulation opening 44 and is supplied to the air supply fan 3.
9 and is further circulated indoors via the air conditioning heat exchanger 40.

[0010]

However, in the above-described conventional air conditioning equipment for treating outside air, two air temperatures different from each other are required.
In addition to the crossing of the two airflows in the total heat exchanger portion, due to the temperature difference between the inside of the main body and the housing and the ceiling behind the airflow passage, dew condensation occurs on the partition plate provided inside and outside of the main body, The installation of a heat insulation layer becomes essential. For this reason, there is a problem that productivity in a manufacturing factory is impaired and manufacturing costs are increased.

In addition, there is a problem that a large number of ducts are required to be installed in the space above the ceiling, which makes the installation at the installation site very complicated.

Further, since the air supply and the exhaust are performed in substantially the same state, the pressure in the room becomes substantially equal to that of the outside air. As a result, in places where there are relatively large entrances and exits, such as stores, etc., which are always open and traffic is intense, problems such as increased air conditioning load due to invading outside air and intrusion of floating dust contained in outside air may occur. I was

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances of the prior art, and has as its object to provide an outside air processing air-conditioning system capable of improving productivity and reducing manufacturing costs with a simple configuration. I have.

It is a second object of the present invention to provide an air conditioner for outside air treatment which enables a ventilator or an air conditioner to operate independently.

Further, a third object of the present invention is to use the inside of the ceiling as a duct to simplify the duct construction at the installation site, improve the workability, and allow outside air to enter the room from the open doorway. It is an object of the present invention to provide an outside air treatment air-conditioning system capable of preventing the air-conditioning operation.

A fourth object of the present invention is to stably blow the conditioned air in the space above the ceiling, and to further selectively control the amount of air to be blown for each room use time zone, for each zone, or for the number of occupants. It is an object of the present invention to provide an outside air processing air conditioning system that can be increased or decreased.

[0017]

In order to achieve the above object, the present invention is directed to an outdoor suction port provided at one end of a main body and an indoor suction port at the other end. A ventilator provided with an air supply fan in communication with the mouth, a chamber chamber formed between the two suction ports, and an air-fuel mixture outlet for communicating the chamber chamber with the outside of the machine; An air-conditioner suction port is provided at one end of the main body, and an air-conditioner air outlet is provided at the other end, and an air-conditioning heat exchanger is provided adjacent to the air-conditioner air outlet and adjacent to the air-conditioner air inlet. And an air conditioner provided with an air conditioning fan, so that the indoor side suction port and the air conditioner air outlet communicate with each other.

Further, in order to achieve the second object,
The installation atmosphere of the air supply fan is set in an isolated state with respect to the chamber, and a first one-way wind pressure shutter that allows an air flow to pass only to the chamber is provided on a partition wall thereof, A second one-way wind pressure shutter that allows the passage of the air flow only to the chamber chamber is provided near each of the indoor-side intake port and the air conditioner outlet port.

[0021]

According to the above-mentioned means, the outdoor air is introduced into the main body of the ventilator through the outdoor-side suction port by the air supply fan, and is blown out to the chamber chamber. In addition, the indoor air is introduced into the main body of the air conditioner from the air conditioner suction port by the air conditioner fan, and after being air-conditioned, is blown out from the air conditioner outlet to the chamber. In the chamber, the air from the air supply fan mixes with the air from the air conditioner,
The mixture is blown out of the device from the outlet. Therefore,
A large amount of air with a uniform temperature can be blown out of the device with a simple configuration, thereby improving productivity and reducing costs.

Also, a first one-way wind pressure shutter provided on a partition wall of the air supply fan, and a second one-way wind pressure shutter installed near each of the indoor side air inlet or the air conditioner air outlet. The directional wind pressure shutter functions to allow the air taken in from the outdoor suction port and the air from the air conditioner to flow only to the chamber. As a result, when the operation of one of the ventilator and the air conditioner is stopped, the inflow of air to the other is prevented, and the air can be prevented from leaking outside (or outside). In addition, independent operation using only one of the ventilation device and the air conditioner is also possible.

Further, the ventilator and the air conditioner are connected to each other and installed inside the ceiling, and the room air supplied into the room from the ceiling is taken in from the opening in the room and introduced into the main body of the air conditioner. After the air is forcibly mixed with the outside air in the chamber, the air is blown out from the air outlet to the ceiling. As a result, the pressure inside the ceiling becomes higher than that in the room,
The air is blown into the room through the indoor air outlet. Therefore, the inside of the ceiling functions as an air-fuel mixture chamber, and the duct construction at the site can be simplified, and the workability can be significantly improved. In addition, there is a relatively large entrance such as a store, and even in a place where the entrance is always open and traffic is intense, floating dust contained in the outside air does not easily enter the room.

Further, the configuration in which the electric fan is installed in the indoor blowout opening provided on the ceiling of the room makes it possible to individually control the operation / stop and strong / weak switching of the fan, and the amount of air blown out from each indoor blowout opening. Can be adjusted individually. Therefore, the mixed conditioned air inside the ceiling can be stably blown into the room, and the amount of blown air can be selectively increased or decreased for each zone in the room.
