Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a damper that is installed on the ceiling and is used to adjust the amount of outside air taken in by an air conditioner that ventilates through a heat exchanger to cool and heat a room.

[Conventional technology]

Fig. 4 is a combination diagram of a conventional ceiling-suspended air conditioner and a damper for adjusting the amount of outside air intake, and Fig. 5 is a cross-sectional view of this ceiling-suspended air conditioner along the - line. A harmonizing machine body, 2 is an air intake port, 3 is a filter for removing dust in the intake air, 4 is a blower, 5 is an outside air intake opening provided on the side plate of the machine body 1, 6 is a cooling medium or a heating medium, A well-known heat exchanger that exchanges heat with the air sucked by the blower 4, 7 is a cooling heat exchanger 6
Drain pan that receives drain water such as dew water, 8
9 is a chamber for distributing heated or cooled air; 9 is an outlet for the air distributed by chamber 8; 11 is a panel having the above-mentioned inlet 2, outlet 9, and inspection door 10, and is attached to the fuselage 1; ,1
Reference numeral 2 denotes an outside air intake duct, which communicates with an opening 5 provided in a side plate of the body 1 via a connecting flange 13. A damper 14 includes a disc 14a, a shaft 14b, and a handle 14c fixed to the shaft 14b, and is rotatably disposed within the duct 12. 15 is an inspection port for the damper 14 provided in the ceiling 16.

In such a configuration, the indoor air sucked through the suction port 2 is removed by the filter 3, and the fresh outside air that has been primarily treated by an outside air processing air conditioner (not shown) is sent to the duct 12 and the damper. 1
Air is sucked into the fuselage 1 through an opening 5 provided in the side plate of the fuselage 1 through a ventilation passage 4.

Here, the indoor air that has passed through the filter 3 and the fresh outside air taken in from the opening 5 are mixed, passed through the blower 4, entered the heat exchanger 6, where they are cooled or heated, and sent to the chamber 8, where they are sent to the air outlet. 9, the air is released into the room as cold or warm air. Further, when it becomes necessary to adjust the amount of outside air taken in, the damper is adjusted through an inspection hole 15 provided at the bottom of the damper 14.

[Problem that the invention attempts to solve]

Since the conventional ceiling-suspended air conditioner is configured as described above, the damper 14 must be arranged and constructed on-site, and an inspection port 15 for adjusting the damper is required, and the damper 14 is installed in the duct. 1
Since the opening was installed inside the 2nd floor, it was not possible to visually check the opening, which caused many problems in terms of cost, ceiling design, and reliability. This invention was made in order to solve the above-mentioned problems, and the purpose is to obtain an air conditioner in which the damper opening degree can be adjusted while visually observing from the indoor air intake port of the aircraft body.

[Means for solving problems]

In the air conditioner according to this invention, a damper for adjusting the amount of outside air is provided at a position inside the machine that can be visually seen from the air inlet when the filter is removed from the air inlet.

[Effect]

The air conditioner according to this invention can adjust the opening degree of the damper while visually observing it from the air suction port, improving operability.

[Example of idea]

An embodiment of this invention will be described below.
Figure 1 is a plan view of a ceiling-suspended air conditioner showing an embodiment of this invention, Figure 2 is a sectional view taken along the - line in Figure 1, and Figure 3 is a detailed view showing the main parts of this invention. be.

In these figures, 1 is a ceiling-suspended air conditioner body, 2 is an indoor air inlet, and 3 is a filter that removes dust from the intake air, and is attached to the air inlet 2. 4 is a blower; 5 is an opening for taking in outside air provided on the side plate of the fuselage 1; 6 is a well-known heat exchanger for exchanging heat between a cooling medium or a heating medium and the air sucked in by the blower 4; 7 is an air conditioner. Time,
A drain pan that receives drain water such as condensed water from the heat exchanger 6, 8 a chamber for distributing heated or cooled air, 9 an outlet for the air distributed by the chamber 8, and 11 the above-mentioned inlet 2 and outlet. A panel 9 and an inspection door 10 are attached to the fuselage 1, and 12 is an outside air intake duct, which is communicated with an opening 5 provided in a side plate of the fuselage 1 via a connecting flange 13. 14 is a damper provided in the fuselage 1 corresponding to the opening 5 provided in the side plate of the fuselage 1, and as shown in FIG. It consists of a fixed rotating member 14b, and a connecting piece 14e for connecting the rotating member 14b to the side plate of the fuselage 1 via a rotating shaft 14d.
An elastic member 14f is inserted into one of the connecting piece 14e and the connecting piece 14e. Further, a handle 14c is attached to one end of the disc 14a. The damper 14 configured as described above is disposed at a position inside the machine where it can be visually seen through the air suction port 2 when the filter 3 is removed.

Next, the operation will be described. The indoor air sucked through the suction port 2 is cleaned by the filter 3. In addition, fresh outside air that has been primarily processed by an outside air processing air conditioner (not shown) passes through the duct 12 and the opening 5 provided in the side plate of the fuselage 11, and an amount corresponding to the opening degree of the damper 14 is released into the fuselage 1. be sucked into.

Here, indoor air and outside air that have passed through the filter 3 are mixed, enter the heat exchanger 6 through the blower 4, are cooled or heated, are sent to the chamber 8, and are cooled or warmed from the air outlet 9. It grows and is released into the room.

On the other hand, if it becomes necessary to adjust the amount of outside air taken in, the panel 11
Open the inspection door 10, remove the filter 3,
While visually observing the disc 14a of the damper 14, the opening degree is adjusted as necessary using the handle 14c. After adjustment, the disc 14a can maintain its adjusted opening degree due to the restoring action of the elastic member 14f held between the rotating member 14b and one of the connecting pieces 14e.

[Effect of idea]

As described above, with this invention, it is possible to adjust the opening of the outside air intake adjustment damper while visually observing it from the air intake port by simply removing the filter from the indoor air intake port. This saves time and effort, and there is no need to provide a separate inspection port, and the damper can be adjusted easily while visually checking.
