Abstract

PROBLEM TO BE SOLVED: To permit space saving in both of the inside and outside of a room and reduce the cost of applying work by a method wherein constituting parts of an air conditioner such as a compressor, heat exchangers, ventilating fan unit and the like are arranged on a base while an air outlet chamber, sending air after heat exchange, is attached to the lower surface of the base. SOLUTION: The constituting components of this water-cooled air conditioner or a compressor 1, a water side heat exchanger 3, an air side heat exchanger 2, a fan 4, a motor for the fan 14 and the like are arranged on a base 5 while an air outlet chamber 6, sending air, whose heat exchange is finished by an air side heat exchanger 2, is attached to the lower surface of the base 5. On the other hand, hanging fittings 9 are attached to the base 5 so as to be capable of being used as a ceiling hanging type air conditioner. According to the hanging fittings 9, the water-cooled air conditioner can be hung from the ceiling. Accordingly, the floor surface of an installation place can be utilized effectively while direct air sending type can be developed and duct applying works become unnecessary. According to this method, space can be saved in both of the inside and outside of a room while the cost of applying works can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a water-cooled air conditioner used in stores, factories and the like.

[0002]

2. Description of the Related Art FIG. 1 shows an example of installation of a conventional water-cooled air conditioner. Conventional water-cooled air conditioners are floor-standing and are divided into two types: duct connection type and direct blow type.

In many cases, the duct connection type is installed in a room (for example, a machine room) different from the room for air conditioning the air conditioner.
A duct is connected to the air outlet of the air conditioner to air-condition the conditioned air. The air is blown out from the air outlet in the ceiling or wall of the room.

The direct-blowing type is installed near the wall surface of the room to be air-conditioned, and blows out the conditioned air from the air outlet of the air conditioner to air-condition the room.

FIG. 2 shows an installation example of a conventional air-cooling type air conditioner. A conventional air-cooled air conditioner is composed of an outdoor unit and an indoor unit, and several indoor units such as a ceiling cassette type are installed on the ceiling surface to air-condition the room.

[0006]

In the case of the conventional water-cooled air conditioner, the floor surface of the room to be air-conditioned for floor placement is occupied by the installation space of the air conditioner. In addition, in the case of duct connection, the construction cost is higher than the direct blowing type by the duct construction cost.

The conventional air-cooling type air conditioner is more expensive than the water-cooling type air conditioner, and requires more space for installing the outdoor unit than the water-cooling type cooling tower. Further, the length of the indoor / outdoor connecting refrigerant pipe is limited as compared with the length of the water pipe between the water-cooled air conditioner and the cooling tower (the pipe length is short), so that the installation location of the outdoor unit is limited.

An object of the present invention is to provide an air conditioner which takes advantage of both of them in order to solve the problems of the conventional water-cooled air conditioner and air-cooled air conditioner.

[0009]

According to the present invention, a compressor, a water side heat exchanger, an air side heat exchanger, a blower, an electric motor for a blower, etc., which are components of a water-cooled air conditioner, are arranged on a base. Then, a blow-out chamber that blows out the air heat-exchanged by the air-side heat exchanger is attached to the bottom surface of the base. Also, hanging brackets were attached to the base so that it would be a ceiling hanging type. The blow-out chamber that blows out air is provided with several blow-out ports so that the air can be blown in various directions, and the blow-out chamber can be removed so that duct connection is possible.

The air conditioner is suspended from the ceiling of the room to be air-conditioned, and the air-conditioned air is blown in multiple directions from the blow-out chamber attached to the bottom surface of the base.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 3 shows a structural diagram of the present invention.
The structure consists of parts such as compressor, blower, air side heat exchanger, water side heat exchanger, blower, electric component box, base, cover and blowout chamber. The compressor, the blower, the air side heat exchanger, the water side heat exchanger, the blower, and the electric component box are arranged on a base having a structure capable of withstanding their respective weights, and are fixed to the respective bases. In addition, the base is fitted with hanging metal fittings for hanging this unit from the ceiling or beam at the installation site. Arrange the components on the base, and make the base strong enough to withstand the weight of the components,
Attach the hanging bracket to the base. Therefore, it is possible to suspend the water-cooled air conditioner from the ceiling, and since the hanging metal fittings are attached to the base on the lower surface of the components, the structure of the covers and frames around the components does not burden the weight and is simple. It is possible to reduce the weight of the unit. Further, by bringing the unit to the ceiling, unlike the conventional floor-standing type, the floor surface is not occupied by the unit installation space, and the space can be effectively used. In addition, since it is a water-cooled type, compared to an air-cooled outdoor unit, the piping length of the cooling tower to be connected is wide and the installation space is small, so you do not have to worry about choosing the installation location. In addition, the price is cheap, which leads to the cost saving of equipment. Since the blowout chamber is provided with blowout ports so that air can be blown separately in four directions, the heat-exchanged air can be blown out directly, which eliminates the need for duct construction and saves construction work. Also, although the blowing chamber is attached to the base,
Since it has a detachable structure, it can be removed during installation work or transportation of the unit, which saves work.
In addition, it is possible to construct a duct from the outlet when necessary.

[0012]

EFFECTS OF THE INVENTION By attaching the hanging metal fitting to the base that supports the weight of the unit, the weight of the outer parts such as the cover and the frame is not burdened, and the unit structure is simplified and the weight is reduced.

By suspending the ceiling, the floor surface of the installation site can be effectively used, and by installing the blowout chamber, a direct blow type is achieved, and duct construction is unnecessary. Also, since the cooling tower to be connected is water-cooled, the cost is lower than that of an air-cooled outdoor unit, and it is easy to select the installation location and secure the installation space. As a result of the above, space is saved both indoors and outdoors, and construction work is also cost-saving.
