Description

Technical Field [0001] The present invention relates to a spraying system for an outdoor unit,

The present invention relates to a mounting structure of a spray apparatus for cooling an air conditioner outdoor unit using latent heat of vaporization, and more particularly, to a mounting structure that is simple to install and can be commonly used in outdoor units of various sizes.

Generally, the air conditioner consists of a compressor, a condenser, an expansion valve, and an evaporator, and uses the refrigerant serving as an intermediate medium of the refrigeration cycle to discharge the heat of the room to the outside. The compressor is operated by the electric motor to compress the gaseous refrigerant and send it to the condenser, and the compressed refrigerant is cooled by liquefying the outside air. When the liquid refrigerant is injected from the expansion valve into the evaporator, it rapidly expands to vaporize and absorbs heat from the evaporator to cool the room air. The gaseous refrigerant returns to the compressor again and is compressed and becomes liquid. This four-stage change of repeated compression, condensation, expansion, and vaporization is called a refrigeration cycle.

In the condenser, a considerable amount of heat is generated when the high-temperature and high-pressure gas refrigerant is liquefied. Typical methods of cooling the condenser include air-cooling and water-cooling, but air-cooling is commonly used. In the air-cooled type, the cooling fin is densely arranged on the surface of the condenser coil through which the refrigerant flows to maximize the cooling effect, and the heat of the cooling fin is released by blowing the outside air with the electric fan. Therefore, the surface of the cooling fin is cooled to condense the gas refrigerant in the coil.

However, the air-cooling method for condensing the refrigerant into the outside air has various problems. First, since the heat capacity of the air is small, a large amount of air to be blown can lead to sufficient cooling performance. For this reason, large-sized electric fans must be used or the heat transfer area must be widened to use high-output air conditioners. Second, when the temperature of the outside air is high, the temperature difference between the refrigerant and the refrigerant is reduced, which makes condensation difficult. If the external temperature is more than 35 ℃, overload will damage the compressor or deteriorate the air conditioner performance. Finally, in the case of a separate type air conditioner, the cooling efficiency may be lowered depending on the place where the outdoor unit is installed. If they are exposed to direct sunlight or close to an outdoor unit adjacent to each other, the ambient temperature rises and the flow of air is disturbed, thereby lowering the cooling efficiency.

In order to solve this problem, the prior art attempts to improve the cooling performance by finely injecting cooling water into the condenser. The basic constitution and the method in Document 1, Document 2, Document 3 and Document 4 are as follows. A condensate or an external water generated in an indoor unit is used as cooling water, and a pump for supplying cooling water at high pressure is provided. Spray into the condenser. The cooling water finely sprayed toward the condenser absorbs heat from the surface of the cooling fin and evaporates, and the latent heat of evaporation improves the cooling performance.

The method of mounting the atomizing device to the outdoor unit to perform the conventional technique can be classified into an internal installation type and an external installation type. The internal installation formula refers to a system in which a spray device is mounted inside a case constituting an outdoor unit, and is shown in Document 5, Document 6, Document 7, and Document 8. In this type of installation, a separate space is provided for installing a spray device in the outdoor unit, and the cooling water is directed so as to be directed toward the condenser. In the external installation formula, a spray device is provided outside the outdoor unit case. Reference 9, document 10, document 11, document 12, and document 13 show various mounting structures.

However, the internal installation method has a problem in installation and a structural problem. In order to install a spraying nozzle, it is necessary to separate the case of the outdoor unit and the space for installing the nozzle and the related parts in the outdoor unit, and work in a narrow space. In addition, there is a drawback that the nozzle mounted inside the outdoor unit and the hose supplying the cooling water to the nozzle interfere with the flow of air and contaminate dust in the air.

Further, in the case of the external mounting equipments 9, 10, 11, 12 and 13, when a plurality of nozzles are provided, the hose route for supplying the cooling water to each nozzle is complicated and the appearance is dirty and it is not clean . In addition, the conventional mounting structure can not be installed in only one direction, so interference may occur in mounting the atomizing device according to the space where the outdoor unit is installed.

In the external installation type document 9, a radial structure made of a wire rod is attached to an outdoor air intake port for mounting a spray device, and a nozzle is mounted in the center of the radial structure. However, since the shape of the outdoor unit and the size of the inlet are different for each output of the maker and the air conditioner, such a mounting structure can not but manufacture the respective structures.

In the external installation type document 13, a structure in which a grip made of a flexible material is provided to the nozzle and the grip is fixed to the rear grill of the outdoor unit is used. However, as described above, the cross-sectional shape of the grill differs depending on the size of the manufacturer and the outdoor unit, and therefore, each grip must be manufactured.

The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a mounting structure which can be easily installed and firmly fixed.

Another object of the present invention is to provide a mounting structure in which a hose route for supplying cooling water is clean and a common structure is possible regardless of the size of an outdoor unit manufacturer and a cooling water is supplied even if a plurality of nozzles are used.

Another object of the present invention is to provide a mounting structure that allows installation of the atomizing device in various directions to avoid interference and does not interfere with the flow of air

According to another aspect of the present invention, there is provided a spraying apparatus including: a manifold having a hollow portion formed therein for receiving cooling water and transferring the same to at least one nozzle; a nozzle connected to the manifold for spraying cooling water; And a clip for fixing and mounting the manifold to the outdoor unit.

The clip is preferably a screw for fixing the outdoor unit case panel, but the panel can be pierced and fixed with a screw if necessary.

It is preferable that two or more clips for fixing the manifold are provided so as to be spaced apart from each other.

The existing outdoor unit case panel fixing screw can be used to fix the manifold with the clip, so that it can be installed without any change, and the atomizing device can be easily installed by unscrewing and tightening the screw.

Since the outdoor unit case has the same structure regardless of the maker and the size, the spraying device and the mounting structure can be used in common, and since a plurality of nozzles can be connected to the manifold, only one supply hose is used. It has a simple and clean appearance.

In addition, since the screw that fixes the outdoor unit case panel is located in various positions, it is possible to fix the manifold in various directions, and the degree of installation is high. When mounting the manifold with a clip, the manifold can be easily rotated to easily adjust the injection angle .

Hereinafter, a mounting structure of a spray apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the mounting structure of the spray apparatus according to the present invention includes a manifold 11 formed in a hollow shape to receive cooling water and transfer it to one or more nozzles 12, And a clip 13 for fixing the manifold 11 to the outdoor unit.

Generally, the outdoor unit has a box-shaped case in which a front panel and a rear panel, both side panels, and an upper panel and a lower panel are combined. In this case, the front panel and the side panel, or the two panels such as the side panel and the rear panel, or the front panel and the upper panel, may be formed by bending the entire panel. The rear panel and one side panel are provided with a suction port for sucking outside air in most areas, and a discharge port through which air introduced into the inside of the rear panel and the front panel through the suction port is formed. The other side panel is provided with an opening for connecting piping and a protective cover to constitute an outdoor unit case.

The length of the screw is sufficient because the thickness of the clip is small even if the clip 13 is fastened by using an existing outdoor unit panel fixing screw. The rear panel with the intake port and the screws to secure the side panel are used, and the panel can be punched and screwed if necessary. The manifold 11 to which the nozzle 12 is connected is rotated when the nozzle 13 is fixed by the clip 13 so as to set the injection direction of the nozzle 12 appropriately. For example, when the manifold 11 is fixed to the upper panel, the nozzle 12 is installed so as to face downward, and is installed at an appropriate angle according to the height of the outdoor unit.
