[0002]

2. Description of the Related Art The above-mentioned air-conditioning and ventilating apparatus of the type described above basically has the following configuration. That is,
An exhaust air path for exhausting indoor air and an air supply path for supplying outdoor air are formed in the main body casing. A part of the exhaust air path and a part of the supply air path are constituted by a heat exchange element having two working fluid passages, and the exhaust air path is provided with an exhaust blower, and the supply air path is provided with a supply air blower. Embedded,
An exhaust flow is formed in the exhaust air passage, and a supply air flow is formed in the supply air passage. In the main body casing, four duct connection ports, which serve as entrance and exit ends of the exhaust air flow and the supply air flow, are provided two on one side and two on the other side. Also, for example, Japanese Utility Model Publication No. 56-32773
As disclosed in Japanese Patent Application Laid-Open Publication No. H10-209, there is a configuration in which a heat exchange element, an air filter, and each of the blowers are individually packaged, and a combination thereof is used to perform an air conditioning and ventilation function.

[0003] The conventional air-conditioning ventilator having the above configuration can supply outside air to a room through a heat exchange element and exhaust indoor air to the outside of the room through the heat exchange element. Ventilation by air supply and exhaust can be performed without using. In particular, in the device disclosed in the above publication, the main functional components are packaged and configured by a combination of these, so that the duct connection port for air supply and exhaust is not fixed, and the characteristics of the installation location Accordingly, a convenient position of the duct connection port can be obtained by combination.

The heat exchange unit 7 has two heat exchange elements 11 and 12 in which two working fluid passages are oriented in the horizontal direction in a parallel state. In the air supply chamber 8, an air blower 13 whose outlet side faces the air supply outlet 5 is incorporated. The exhaust flow formed by the exhaust blower 9 merges from the exhaust suction port 4 through one of the working fluid passages extending obliquely rearward from the front of each of the heat exchange elements 11 and 12 of the heat exchange unit 7 in the drawing. Air is blown from the chamber 6 to the exhaust outlet 2 via the exhaust blower 9. The supply air flow formed by the supply air blower 13 is guided from the supply air inlet 3 to the heat exchange unit 7 by the internal duct 10,
The heat exchange elements 11 and 12 merge through the other working fluid passages extending obliquely forward from the rear in the drawing, and blow out from the air supply chamber 8 to the air supply outlet 5 through the air supply blower 13. The exhaust air path and the air supply air path through which the exhaust air flow and the air supply air flow pass do not pass through the working fluid passages of the heat exchange elements 11 and 12, respectively, from the exhaust air inlet 4 to the exhaust chamber 6, and from the air intake air inlet 3. Bypasses 14 are respectively connected to the air supply chambers 8. The heat exchange part 7 serving as the outlet end of each bypass 14, the exhaust chamber 6, and the air supply chamber 8

Supply / exhaust ventilation (air conditioning ventilation) involving heat exchange between the exhausts can be performed. Further, the damper 15 of the exhaust air passage and the damper 15 of the supply air passage are opened to open each bypass 1.
4 is opened, the exhaust air flow and the supply air flow are
It is also possible to exhaust and supply with a large air volume without passing through 12,
A comfortable environment in the interim period such as spring and autumn can be thereby formed. The feature of this air-conditioning ventilator is that the exhaust air outlet 2 and the air supply inlet 3 which communicate with the outside of the room by the duct are on the upper surface of the main body casing 1, and the exhaust air inlet 4 which communicates with the indoor side by the duct and the air supply Outlet 5 is main body casing 1
Is arranged on the front surface of the main body 1, thereby facilitating the connection work of the ducts. In addition, since the connection space for the ducts communicating with the outdoor side is accommodated in the projection plane of the main body casing 1, extra space is provided. This means that the entire installation area is smaller than before.
Even if it is necessary to bend the connecting duct between the exhaust air outlet 2 and the supply air inlet 3, the bent part also has a main casing 1
In the projection plane. Heat exchange element 1
By incorporating the elements 1 and 12 in parallel, it is possible to reduce the vertical dimension of the entire apparatus without lowering the heat exchange capacity.
