BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation air conditioner capable of performing air conditioning together with ventilation.

[0002]

2. Description of the Related Art This type of ventilating air-conditioning apparatus has a heat exchange ventilation function and a cooling / heating function. Conventionally, for example, Japanese Patent Publication No. 4-40615 and Japanese Patent Laid-Open Publication No. 1-1551
The configuration is as shown in Japanese Patent Publication No. 32. In the former, a ventilation part performing a ventilation function and an air conditioning part performing an air conditioning function are adjacently formed and integrally formed, and the ventilation part is provided with an exhaust blower that forms an exhaust flow for exhausting indoor air to the outside. Exhaust passage, an air supply passage provided with an air supply blower for forming an air supply flow for supplying outdoor air to the room, and a heat exchanger for performing heat exchange between the exhaust air flow and the air supply flow. ing. The air-conditioning unit includes an air passage provided with a blower for forming an airflow that takes in room air and blows out the room, and an air-conditioning heat exchanger interposed in the air passage. However, the above-described structure, which is integrally formed as a whole, is easy to handle because it is a unit. However, the installation space is limited, the weight is large, and much labor is required for installation.

The latter problem has been solved by configuring the ventilator 101 and the air conditioner 102 to be separable as shown in FIG. In this ventilation air conditioner, the ventilation unit 10
1 and the air-conditioning unit 102 can be integrated or separated from each other and connected to each other by a duct 103. This improves the workability and workability, and improves the compatibility with the installation location. ing.

In such a ventilation air conditioner, the ventilation unit 1
When the air conditioner 01 is operated, the indoor air is sucked into the exhaust passage from the indoor air intake, passes through the heat exchanger 104, and is exhausted to the outside. At the same time, outdoor air is also drawn into the air supply passage,
After passing through the heat exchanger 104 and performing heat exchange with the exhaust gas flow, the air is blown into the room from the air outlet through the air passage of the air conditioning unit 102. When only the air conditioner 102 is operated, room air is sucked into the air passage from the room air inlet, passes through the air conditioning heat exchanger 105, and is blown back into the room as warm or cold air. When both the ventilation unit 101 and the air conditioning unit 102 are operated, a part of the indoor air is mixed with the outdoor air sucked into the ventilation unit 101 and passes through the air conditioning heat exchanger 105 as it is. Is blown out to
The other part is sucked into the exhaust passage of the ventilation unit 101 and exhausted outside the room.

In the conventional ventilating and air-conditioning apparatus as described above, the ventilating unit 101 and the air-conditioning unit 102 can be separated from each other. There is a problem that it is heavy and difficult to handle when installed. In addition, when the ventilation unit 101 and the air conditioning unit 102 are separated from each other, a connection operation by the duct 103 is required, which tends to reduce workability and complicate the configuration.

It is not only impossible to carry out the ventilation that matches the characteristics of the air conditioner, but also it is difficult to make the air conditioner 102 correspond to the difference in the type of the heat source. These problems can be solved, for example, by adopting a configuration in which each functional body is configured as a unit and the units are replaceable and each unit is connected by a duct or the like, but the number of connection operations by the duct increases, as described above. The workability at the time of installation will be greatly reduced.

[0007] As technologies related to air conditioning to be taken into consideration, several technologies for giving flexibility to the combination of units have been disclosed. For example, Japanese Unexamined Patent Publication No.

The technology of the connection structure is shown. However, even if such a technique is applied to a ventilation air-conditioning apparatus as it is, the configuration becomes complicated, the operation of the connection port and the connection parts become complicated, and the workability and workability are impaired, so that a very good result cannot be obtained.

[0019]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram showing a planar configuration of a ventilation air-conditioning apparatus according to one embodiment of the present invention. This ventilating air-conditioning apparatus has a configuration in which a ventilating unit 1 and an air-conditioning unit 2 are adjacent to each other. It is installed using the space above the ceiling. The ventilation unit 1 is configured by connecting the blower unit 3 and the heat exchange unit 4 on their side surfaces. The blower unit 3 mainly includes an exhaust blower 5 that forms an exhaust flow for exhausting indoor air to the outside, and an air blower 6 that forms a supply flow for supplying outdoor (mostly outdoor) air to the room. The exhaust blower 5 is provided in an exhaust passage 7, and the air supply blower 6 is provided in an air supply passage 8 provided independently of the exhaust passage 7. One end of the exhaust passage 7 and one end of the air supply passage 8 are opened on one side of the blower unit 3 so as to be duct-connectable. The other end of the exhaust passage 7 and the other end of the air supply passage 8 are individually opened on the other side surface of the blower unit 3.

As the blower unit 3, several types having different capacities of the exhaust blower 5 and the supply blower 6 are prepared, and one that is suitable for the characteristics of the space to be ventilated and the installation place is used. However, each of the blower units 3 has the same configuration except for the blowers of the exhaust blower 5 and the supply blower 6.

The heat exchange unit 4 is mainly composed of a ventilating heat exchanger 9 for performing total heat exchange with air, and has an air supply passage 10 communicating with one working fluid passage of the heat exchanger 9 and the other. And an exhaust passage 11 communicating with the working fluid passage. The ends of the air supply passage 10 and the exhaust passage 11 are respectively opened on both sides of the heat exchange unit 4. When one side of the heat exchange unit 4 is joined to one side of the blower unit 3, the air supply passages 8, 10 and the exhaust passages 7, 1 of both units are joined.
1 communicates with a series of air supply passages and exhaust passages. The connection between the blower unit 3 and the heat exchange unit 4 is made by butting of the side surfaces. However, the connection is unstable by itself, so a connection structure 12 as shown in FIG. 2 is provided.

That is, one side of the blower unit 3 is provided with a connection tube 13 surrounding the side surface around the periphery thereof, and one side of the heat exchange unit 4 is configured to be able to fit inside the connection tube 13. . The fitting between the blower unit 3 and the heat exchange unit 4 is maintained by tightening with the screw 14 from the outside of the connection tube portion 13, and the fitting can be released by removing the screw 14 and pulling out the fitting to remove the fitting. It is.

An indoor air intake unit 15 is connected to the heat exchange unit 4 connected to the blower unit 3 on the side opposite to the blower unit 3 by the connection structure 12 described above. The indoor air intake unit 15 is connected to the end of the air supply passage 10 of the heat exchange unit 4, one end of which is connected to the room through a duct or the like, and the end of the exhaust passage 11 of the heat exchange unit 4. , And one end thereof is provided with an intake passage 17 which can also be connected to the room via a duct or the like. On the side of the indoor air intake unit 15 opposite to the side where the heat exchange unit 4 is connected, one end of an intake passage 16 communicating with both the room and the air supply passage 10 of the heat exchange unit 4 is opened. The indoor air intake unit 15 is substantially an air chamber, and the inside is not clearly divided into the intake passage 16 and the intake passage 17. Therefore, it is also possible to directly connect one side of the blower unit 3 and one side of the indoor air intake unit 15 without using the heat exchange unit 4. Since the working fluid passages of the heat exchanger 9 intersect with each other via the heat exchange unit 4 and not through the heat exchange unit 4, the supply passages 8, 10 and the exhaust passages 7, 11
The relationship between the indoor air intake unit 1
There is no functional hindrance merely by changing the indoor air intake in 5.

The air conditioning unit 2 is connected to the indoor air intake unit 15 by the same connection structure 12 as described above. The air conditioner 2 is also configured by connecting the heat exchange unit 18 and the blower unit 19 on their side surfaces. The heat exchange unit 18 mainly includes an air-conditioning heat exchanger 20 for exchanging heat between a heat source and air, and the heat exchanger 20 is interposed in a processing air passage 21 formed therein. One side of the heat exchange unit 18 is connected to one side of the indoor air intake unit 15, and one end of the processing air passage 21 is communicated with one end of the intake path 16 of the indoor air intake unit 15.

The blower unit 19 is mainly composed of a blower, and in this embodiment, two blowers 22 and 23 are incorporated in parallel. Each of the blowers 22 and 23 is incorporated in a processing air passage that is independently arranged inside and is formed therein, and forms an airflow in the same direction in each processing air passage. One side of the blower unit 19 has an opening on the suction side of each processing air passage, and the other side has an opening on the blowing side of each processing air passage for duct connection. The heat exchange unit 18 and the blower unit 19 are also connected by the connection structure 12 shown in FIG.

In this embodiment, the air conditioning unit 2
2 and 23 are separated by a partition plate 24 to be independent, and the air-conditioning heat exchanger 20 is commonly used. However, a single blower may be used, or the air-conditioning heat exchanger may be used. The vessel 20 may be divided into two parts by a partition plate or the like.

There are several types of air-conditioning heat exchange units 18 incorporating heat exchangers 20 corresponding to the types of heat sources, so that they can be used for both direct expansion type heat sources and cold / hot water type heat sources. ing. However, the heat exchange unit 18 corresponding to any of the heat sources has the same configuration except for the heat exchanger 20.

When the ventilating air-conditioning apparatus having the above-mentioned structure is installed, for example, behind a ceiling, as shown in FIG.
5, the blower unit 3, the heat exchange unit 4, the indoor air intake unit 15, the heat exchange unit 18, and the blower unit 19 are sequentially mounted on the opposed common rail 26 suspended and fixed in a manner to connect the trains. What is necessary is just to connect mutually by the connection structure 12, and to connect and connect. Each unit is not so large and easy to handle, and when supported by the rail 26 as described above, it can be constructed by one worker alone. Further, since the connection between the units is a direct connection without passing through a duct, the workability and the workability are good, and the configuration itself for connection is simple.

When the air conditioner 2 is operated by flowing cold water or hot water (refrigerant) as a heat source into the heat exchanger 20 for air conditioning in the ventilating air conditioner of this embodiment, the blowers 22 and 23 convert the indoor air into the indoor air. It is taken in via the intake unit 15 and processed for cooling and heating, and is supplied as processing air to the supply target room via a duct. When the ventilation unit 1 is operated to perform ventilation, the outdoor air taken in through the air supply passages 8 and 10 exchanges heat with the exhaust flow in the heat exchanger 9 and then passes through the indoor air intake unit 15. The air is mixed with the air in the room to be sucked, flows into the processing air passage 21, is processed for cooling and heating, and is supplied to the supply target room via the duct. On the other hand, the operation of the exhaust blower 5 causes the indoor air intake unit 1 to operate.
The indoor air sucked in through the air outlet 5 is exhausted from one side of the blower unit 3 through the heat exchanger 9 and the exhaust passages 11 and 7 to the outside through the duct. That is, the ventilation by the introduction of fresh outside air and the exhaust of the polluted room air to the outside of the room is performed together with the cooling and heating.

In each of the chambers to which the processing air is supplied by each of the blowers 22 and 23, for example, 400
Processing air is supplied at each air volume. Exhaust by the ventilation unit 1 is performed at an air volume of 150, for example, and air supply is also performed at
It is carried out with an air volume of zero. In the air-conditioning unit 2 into which the supply airflow from the ventilation unit 1 is sucked, 150 is used for air supply and 400 is used for blowing indoor air.
When necessary, 250 is sucked in from the indoor air intake unit 15 and 150 is sucked in the exhaust air.

In a warm climate area, ventilation with heat exchange as described above may not always be necessary, but the apparatus of this embodiment can easily cope with such regional characteristics. That is, the heat exchange unit 4 of the ventilation unit 1 may be removed, and the ventilation unit 3 and the indoor air intake unit 15 may be directly connected to form a ventilation air conditioner that does not include the heat exchanger 9. When it is necessary to increase or decrease the amount of air required for ventilation, the ventilation unit may be configured by selecting an air supply unit 3 having an appropriate air supply performance. Furthermore, it is possible to easily cope with a difference in the type of the heat source by configuring the heat exchange unit 18 corresponding to the heat source.
