Description

Outdoor unit for air conditioner {OUTDOOR UNIT FOR AIR CONDITIONER}

The present invention relates to an outdoor unit for an air conditioner, and more particularly, to an outdoor unit for an air conditioner that can be installed indoors.

Conventional air conditioners with a refrigerant cycle consist of an integral type and a separate type, which are divided into indoor units and outdoor units. In addition, the air conditioner is divided into a cooling cycle and a heating cycle according to the circulation direction of the refrigerant cycle. An air conditioner of such a cooling cycle includes an indoor unit installed indoors to cool an indoor unit, connected by an indoor unit and a refrigerant pipe, and installed outside to contact the atmosphere to condense heat exchange and condensate refrigerant gas using external air as a cooling medium. It consists of an outdoor unit for flowing the refrigerant to the evaporator of the room. The indoor unit is composed of an evaporator for cooling and heat-exchanging the indoor air by evaporating the refrigerant, and a ventilation fan for circulating the indoor air.In the outdoor unit, a compressor for compressing the refrigerant gas to flow to the condenser and an air-cooling type for condensing the refrigerant gas flowing from the compressor A condenser and a cooling fan for cooling and condensing the refrigerant gas by forcibly venting external air to the air-cooled condenser. The compressor, air-cooled condenser and cooling fan are housed in a casing that forms the exterior. On the rear or side of the casing is provided an air supply for supplying air to the air-cooled condenser inside the casing, and on the front or the upper surface of the casing is provided an air exhaust for exhausting the air absorbed by the condensation heat to the outside of the casing. .

However, in the conventional outdoor unit for an air conditioner, due to the high density of the city and the strengthening of environmental management, it is a target for the civil complaints of the surroundings due to the limitation of the outdoor installation place, the noise and the heat emission. In particular, common residential facilities such as apartment complexes are regulated to install outdoor units on the veranda of indoors due to aesthetics and noise problems.In some cities, outdoor units installed around India have been changed to upward heat emission structure in order to manage pleasant urban environment. The building legislation is attempted, and due to environmental awareness and quality of living culture, conventional outdoor units are increasingly restricted in the installation place. It is now common to install such a conventional outdoor unit in an interior of an apartment porch and open a window and use an outdoor unit without technical considerations, which are easy to install and operate indoors, but in this case, there are many side effects. In case of operating outdoor unit in the room near the window with exhaust louver considering crime prevention and more efficient exhaust, it is necessary to open the window to guide the outdoor air to the indoor unit and supply it to the outdoor unit. As heat is flowed back to the room and the room temperature is increased, the cooling efficiency of the condenser may be lowered, and heat loss of the cooling room may be caused by the supply / exhaust that is not isolated from the room air. Even if you open one or more windows and operate the outdoor unit, if the heat from the outdoor unit is not completely exhausted and is partially recycled, the room temperature will rise and the heat loss will be incurred. In addition, there is a problem in crime prevention as well as indoor exposure from the outside, it is inconvenient to open and close windows one by one when driving. In addition, there is a problem that the operating noise of the outdoor unit is transmitted to the room by opening the air supply and exhaust ports of the outdoor unit. As described above, the conventional indoor unit is difficult to form a supply / exhaust unit separated from the indoor air due to its structure, and is installed in a basement or an interior spaced apart from the outside and cannot be operated by combining the supply / exhaust duct. It is common to install in a place close to the window. In order to solve the problem of indoor installation of the outdoor unit, a technology designed to directly discharge the outdoor unit exhaust from the indoor air and discharge it to the outside has been disclosed by the outdoor unit discharge guide device of the separate air conditioner of Utility Model Publication No. 1999-030847. .

Accordingly, it is an object of the present invention to provide an outdoor unit for an air conditioner that can be installed indoors, does not affect indoor air and the environment, reduces noise and heat loss, and can be installed even at a predetermined distance from the outside. .
