DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is installed on a ceiling of a room having a large area such as a hall, an exhibition hall, a factory and the like, and flows indoor air stagnating around the ceiling and mixes it with fresh outside air to cover the entire room. The present invention relates to a ceiling-mounted air conditioner that distributes cooling and heating air almost uniformly.

[0002]

2. Description of the Related Art Conventionally, as a means for cooling and heating a relatively large area such as a hall as described above, a necessary number of cooling and heating air conditioners are installed and used at appropriate places such as a floor or ceiling in a room. However, depending on the area, etc., as well as the installation location, the indoor air is not completely recirculated and stays in high places in the room, especially on the ceiling side, etc., thereby significantly contaminating the indoor air. It was a serious problem in health management. Even if the above exhaust is completely performed, the amount of heat for cooling and heating the room is discarded together with the contaminated air, which is very uneconomical.

[0003]

SUMMARY OF THE INVENTION In view of the above problems, the present invention has been made in consideration of the above-described problems, and has a cooling / heating device which also serves as a circulator.
In other words, it is intended to ensure that the air stagnating around the ceiling is completely circulated and that fresh air is efficiently and reliably delivered to the entire room. Its main purpose is to efficiently deliver warm winds.

[0005]

The present invention has the above structure, and is installed at a corner of a ceiling at a high place in a room, such as a hall, and connects the air outlet 3 and the suction port 4 of the body 1 to the indoor side. Next, the outside air introduction port 2 and the exhaust port 5 are installed on a wall surface so as to be led out of the room. By operating both the suction and exhaust blowers 6 and 7 installed on the left and right sides in such a state at the same time, fresh outdoor air passes through the ventilation passage A from the outside air inlet 2,
Appropriate cooling / heating air is blown into the room from the air outlet 3 in front of the body 1. On the other hand, the air on the indoor side is discharged from the suction port 4 through the ventilation passage B to the outside through the exhaust port 5, and the total heat exchanger 8 installed between the upper and lower ventilation passages A and B during the airflow inside the machine.
By recovering a part of the amount of heat in the indoor air by the action of the above, a certain amount of heat is applied to the introduced air at the same time, so that the amount of heat in the exhaust gas can be used economically.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. An airframe 1 is formed of a horizontally long casing, and an air outlet 3 is provided diagonally forward and downward, and a room is provided on the lower surface. Air inlets 4 are provided at respective openings, and both sides of the body 1
The blower 6 for suction and return air and the blower 7 for
Outside air inlet to be installed and opened on one side of the back of the fuselage 1
Inverted U-shaped ventilation passage between the air outlet 2 and the air outlet 3 opened at the front of the room
At A, the air return port, suction port 4 on the indoor side and the back of the fuselage 1
And at a considerable distance from the outside air inlet 2
Exhaust port 5 to be opened on the side and exhaust and return air ventilation passage B
It is connected and connected in a cross shape, and furthermore, the upper and lower ventilation passages A and B
45 ° inclined horizontal total heat exchanger 8 in the cross section between
With respect to the blowing direction of the suction and return air blower 6
It is installed almost in parallel, and in FIG.
Fresh air introduced from outside air inlet 2 as shown
It passes through the upper side ventilation passage A of the horizontally long total heat exchanger 8
Is the upper part between the fins of the total heat exchanger 8 during the passage.
Bent downward at an angle of approximately 45 °
Sent inside.

Further, the air flow is switched between the two air passages A and B.
It is also possible to install a damper 9 for the room and return the whole or a part of the room air to the room again without directly exhausting the whole amount of room air to the outside, so that the amount of heat in the room air can be used more effectively. It is.

[0008]

As described above, the ceiling-mounted air conditioner according to the present invention is provided with an outside air inlet 2 and an exhaust port 5 on both left and right sides of a body 1 formed in an elongated shape corresponding to the entire length. Suction and return air blower 6 and blower and exhaust blower 7
Is installed, and the inverted U-shaped air passage A and exhaust
And a return air blowing passage B formed in a cross shape.
Cross section between roads A and B, sideways between left and right blowers 6 and 7
The long total heat exchanger 8 is set at an inclination angle of 45 ° and the above suction,
It should not be installed almost in parallel with the blow direction of the return air blower 6.
Air flow inside and outside the cabin that can be introduced into the cabin.
Naturally and very smoothly distributed,
It has economic effects such that the amount of heat in the air can be used most effectively and the amount of heat used can be greatly reduced. In particular, in the present invention, the overall shape of the total heat exchanger 8 is as described above.
Formed into a horizontally-long shape and stagnate widely on the ceiling of indoor high places
Air that conveys contaminated air smoothly and reliably
More efficient mixing of indoor air with indoor air
This allows ideal air to be quickly distributed throughout the room.
There are also effects such as gain . Moreover, the entire casing is connected to the total heat exchanger 8.
Since both are formed in an elongated shape, the corner of the ceiling
It can be easily installed in corners, narrow places, etc.
In comparison with conventional bulky ceiling-mounted air conditioners,
It also has the advantage that the installation area can be reduced as much as possible.
You. Further, the outside air inlet 2 and the exhaust port 5 are
Opened on both sides and at a considerable distance
In general, when introducing fresh outside air,
It was said that it was a drawback in the past without any worries such as mixing
The outside air introduction and the contaminated air are mixed and naturally sent into the room.
Can be solved fundamentally
It is.

Further, in the present invention, as described in claim 2, an airflow switching damper 9 is provided at an appropriate position between the upper and lower airflow passages A and B, without discarding the whole amount of indoor air to the outside. By recirculating the whole or a part of the air to the room again, there is also an economic effect such that the amount of heat in the discarded air can be more effectively used.
