Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention mainly relates to an air conditioner for commercial use.

[Prior Art and Its Disadvantages] A conventional air conditioner is configured for each air conditioner, and is provided with an intake duct for return air.

Therefore, in the case of multiple air conditioners, each requires an intake duct, resulting in high costs and troublesome installation work.

[Purpose of the present invention] The purpose of the present invention is to use the space between a pair of left and right air conditioners mainly as an intake duct for return air from the room, and therefore there is no special need for an intake duct for return air. An object of the present invention is to provide an air conditioner that does not cause any problems, has low manufacturing costs, and is easy to install.

[Means of the Present Invention] The air conditioner of the present invention includes a pair of left and right casings each containing a cooler, a filter, and a blower, and having air ports in each upper plate portion and opposing side plate portions. A space for forming a duct is provided, and a closing plate that also serves as an entrance/exit door is provided in front of this duct space.

[Embodiment] An embodiment of the present invention will be described below with reference to a specific example shown in the accompanying drawings.

In the figure, symbol A indicates the left air conditioner, and symbol B indicates the right air conditioner.

The left air conditioner A has casing 1A as shown in Figure 2.
Cooler 2, filter 3, humidifier 9, blower 4 inside
The air outlet 5A, which is an air outlet, is provided in the upper plate.

Just like the left air conditioner A, the right air conditioner B is equipped with a cooler, a filter, a humidifier, and a blower in the casing 1B (not shown), and an air outlet 5B, which is an air outlet, is opened in the upper plate of the casing. There is.

The left and right air conditioners A and B are arranged with a space S for forming a duct, and a closing plate 6 is provided at the front of the space S between the two air conditioners. Air ports 7A and 7B serving as suction ports are provided at the lower portions of the opposite sides of the air conditioner, that is, the right side plate of the left air conditioner and the right side plate of the left air conditioner, respectively.

Further, the closing plate 6 is constructed with an opening/closing door, so that the space can be entered and exited during maintenance or the like.

In addition, in the illustration, symbols 8A and 8B indicate front doors of the left and right air conditioners.

The air conditioner of this embodiment is installed and used as shown in FIGS. 1 and 3, for example.

That is, this device is installed in a machine room R2 separated from an air-conditioned room R1, with the back side of the device in close contact with the wall surface 10 of the same room, and a blocking plate is installed between the opposing side plates of the left and right air conditioners 1A and 1B. 6 and the space S with the wall surface of the machine room constitute a duct.

However, the upper air outlet 5 of the left and right air conditioners A and B
A, 5B connect the air supply port 11 to parallel inlets 12A, 12B of the air supply duct 12 that opens into the air conditioned room R1, and also connect the return air suction port 13 to the upper part of the space S between the left and right air conditioners. connects the other end opening 15 of the return duct 14 which opens into the air-conditioned room R1.

In the air conditioner installed in this way, the return air that has passed through the return duct 14 from the air conditioned room R1 enters the space S between the left and right air conditioners A and B, and the return air in the same space is distributed between the left and right air conditioners. The air is sucked into the air conditioners A and B from the suction ports 7A and 7B on the opposite side plates, and the sucked air is purified and cooled by the filter 3 and the cooler 2, and then sent from the supply air duct 12 to the air-conditioned room by each blower 4. The air is sent to R1 again and air-conditions the air-conditioned room R1.

Fig. 4 shows a schematic diagram of a plane in which two units of this device are installed back to back. By installing this device in this way, the space S between the left and right air conditioners is closed by the front and rear closing plates 6, 6, and the air intake duct for return air is formed. It is not necessary to use the walls of the room to configure the duct.

[Effect] According to this device, the space between the left and right air conditioners can be configured as a return air duct using the front closing plate and the wall of the installation room, or two devices can be installed back to back. As a result, the space between the left and right air conditioners can be configured as an intake duct for return air using the front and rear closing plates, so there is no need to separately manufacture intake ducts for the return air for the left and right air conditioners, and this reduces the equipment cost. Expected to reduce production costs.

Further, since the closing plate between the left and right air conditioners also serves as a door, it is possible to enter and exit the intake duct formed by the space between the left and right air conditioners, making maintenance and maintenance easier.
