Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner installed on a ceiling.

[0002]

2. Description of the Related Art Conventionally, as an air conditioner of the type installed on the ceiling side, a casing having a compressor, a condenser, an evaporator and a blower is all installed in a ceiling foot, and an air inlet and an air outlet are ducted. There are a concealed type that is connected to the indoor side to perform air conditioning, and an exposed type that has the casing attached to the underside of the ceiling board and is entirely exposed to the indoor side.

[0003]

However, since the conventional concealed type is installed in the space of the ceiling back, it was not conventionally suitable for a large unit. In addition, the exposed type can blow air in a horizontal direction in parallel with the ceiling, but since the casing is entirely exposed, the volume occupying the indoor space is large, and it is not preferable from the viewpoint of appearance. , Giving the residents a sense of oppression.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an air conditioner which can omit duct work and does not occupy much indoor space. Moreover, in the present invention, the degree of freedom of the cooling water pipes (and electric wiring) is obtained, the work is easy, and these pipes are made invisible from the inside of the room (house), so that they are good in appearance. The driving noise is not transmitted directly into the room, so that the noise is low. In addition, any space in the room (by the window,
It can be installed even in the center of the room), and as a unit that can be installed without a ceiling, the degree of freedom of the installation location is increased.

[0005]

According to a first aspect of the present invention, a condenser, a compressor, and an electric box are housed in an upper part of an air conditioner (half-filled water cooling package), and an evaporator and a blower are arranged in a lower part. And an air inlet and an air outlet are provided.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. 1, 2 and 3 are a sectional view, a plan view and a perspective view, respectively, showing an embodiment of an air conditioner according to the present invention. In each of the figures, reference numeral 1 denotes a lower casing made of a box having an appropriate thickness. The lower casing 1 is located below the ceiling board 2. An air inlet 3 provided with a filter is provided on the rear wall 1a side of the lower casing 1, and an air outlet provided with a grill panel for distributing air upward, downward or left and right is provided on the front wall 1b side. 4 is installed.

In the lower casing 1, an evaporator 5, a blower 6, and an air discharge space 7 are provided in order from the air inlet 3 to the air outlet 4.

On the rear upper surface of the lower casing 1, a horizontally long upper casing 8 is provided. The upper casing 8 is located at the ceiling foot 9 of the ceiling board 2, inside which a compressor 10 and a condenser 11 are arranged on the left and right sides, and a distribution switch box (electric box) at its end. 12 are arranged.

Further, cooling water outlets 12a and 12b are located on the left and right side surfaces of the upper casing 8, and cooling water inlets 13a and 13b are located therebelow. Cooling water outlet 1
2a, 12b Common piping 14 and cooling water inlet 1
A common pipe 15 that connects the elements 3a and 13b is connected to the capacitor 11.

In this case, when one of the cooling water outlets 12a and 13a is used, the other cooling water outlet 12a is used.
b, a plug is provided at the cooling water inlet 13b and closed.
When the other one is used, on the contrary one side is provided with a plug and closed.

A cooling water ring and a supply pipe 16a, 16b from a cooling tower installed on a roof or the like (not shown) are provided with a cooling water outlet 12a and a cooling water inlet 13a in accordance with the convenience of pipe routing.
Alternatively, it is connected to one of the cooling water outlet 12b and the cooling water inlet 13b.

Incidentally, at an appropriate place of the lower casing 1,
A clamp 20 is attached to the lower ends of the stays 19, 19 hanging from the ceiling slab 18, by screws. Further, a drain pump is provided on the lower casing 1 side, and the coil drain is connected to the compressor and the drain on the condenser side so as to be integrated with the drain pipe. For example, a three-phase power distribution line 21 is guided to the distribution switch box 12. 22 is a drain pipe port.

The operation of the above configuration is as follows. When the compressor 10 is energized and operated, the refrigerant is compressed and circulated through the condenser 11 to the evaporator 5 to cool the evaporator 5. The air sucked from the air inlet 3 by the blower 6 is cooled by the evaporator 5 and then discharged from the air outlet 4 through the air discharge space 7 and substantially horizontally along the lower surface of the ceiling board 2. After being blown out, it circulates indoors,
Indoor cooling is performed. At the time of heating, it may be blown slightly downward and circulate indoors.

On the other hand, the condenser 11 condenses the refrigerant. The cooling water introduced into the condenser 11 enters the cooling water inlet 13a or 13b, cools the condenser 11, and then cools the cooling water outlet 12a or 12a. From 12b, it is circulated to a cooling tower installed on a rooftop or the like.

According to the present invention, noise based on the operation of the compressor 10 is cut off at the ceiling foot 9,
Noise that goes out indoors can be reduced.

When a drain pump is provided on the lower casing 10 side, the coil drain can be guided to the compressor 10 and the condenser 11 section. As a result, the drain of the compressor and the condenser section joins and the local drain pipe becomes one. It is easy to secure the drain gradient even when this unit is installed in the center of the room because of the construction cost reduction. Further, there is an advantage that the drain pipe cannot be seen when the unit is viewed from the indoor side. However, this drain pump may not be equipped depending on the installation condition of the unit. Also, the air outlet 4 faces downward,
It may be provided in the lower part of the lower casing 1.

FIG. 4 shows an example of installation of an air conditioner according to the present invention. In this case, four pillars are surrounded by the pillar C so that the rear air inlet side is located on the pillar C side of the center of the beams A and B. Shows the side where the machine is installed. In this case, the common pipes 30 and 31 are provided so as to surround the column C, and each of the air conditioners 1
The cooling water outlets and inlets of A, 1B, 1C and 1D are connected. According to this, since each air conditioner is installed in a column shape so as to blow air in four directions at a right angle of 90 degrees,
Air can be blown in the radial direction.

[0018]

As described above, according to the present invention,
The upper part of the air conditioner houses a condenser, a compressor and an electric box, the lower part houses an evaporator and a blower, and has an air inlet and an air outlet, so it occupies a lot of indoor space. Noise from the compressor.
