The present invention relates to an outdoor unit for an air conditioner having a front suction and discharge method for exchanging heat with a refrigerant passing through the condenser by blowing the outdoor air to the front of the case in which the compressor and the condenser are installed. The present invention relates to a compressor installation structure of an outdoor unit for an air conditioner of a front air suction / exhaust system that can be easily separated from a case so as not to interfere with other components even if a plurality of compressors are installed as it is increased.

Air conditioners including both air conditioners or heaters can be divided into one-piece and separate types. In the case of describing the air conditioner as an example, the separate type air conditioner, which is the object of the present invention, is installed indoors to cool the room, and is connected to the indoor unit and the refrigerant pipe, and is installed in the outdoor contact with the air to provide external air to the cooling medium. It consists of an outdoor unit that supplies the condensed refrigerant after condensation heat exchange with the refrigerant gas in the condenser to the evaporator of the indoor unit through the refrigerant pipe. The indoor unit includes an evaporator for cooling heat exchange to absorb evaporative heat from the indoor air by evaporating the refrigerant, and a ventilation fan for circulating the indoor air. The outdoor unit includes a compressor for compressing the refrigerant gas and supplying it to the condenser, and a refrigerant gas supplied from the compressor. An air-cooled condenser for condensing, and a cooling fan for cooling and condensing the refrigerant gas by forcibly blowing external air to the air-cooled condenser. The compressor, the air-cooled condenser and the cooling fan of the outdoor unit are accommodated inside the outdoor unit case forming the exterior. The conventional hexahedron outdoor unit case has an air inlet for sucking air into an air-cooled condenser on three sides, and an air for discharging the air absorbed from the refrigerant gas to the outside through heat exchange in an air-cooled condenser on its upper surface. The discharge part is provided.

However, such a conventional outdoor unit for an air conditioner has been restricted in the installation place due to the high density of the city and the strengthening of environmental management, and has been subjected to complaints of the surroundings due to noise and heat emission. In particular, common residential facilities, such as large apartment complexes, require outdoor units to be installed inside the veranda due to aesthetics and noise problems.

Therefore, recently, many outdoor air absorber-type outdoor air conditioners have been developed such that the outdoor air is sucked out into the open space at the front and heat exchange is performed with the condenser. The problem is that the flow resistance is greatly generated due to the limited space in which air is absorbed and discharged, so that the blowing efficiency and the heat exchange efficiency are lowered. In order to increase the heat exchange capacity of the refrigerant, not only a large-capacity compressor but also a condenser having a large heat exchange capacity is used.

As described above, the use of a large-capacity compressor in a large-capacity front suction / outtake air conditioner increases the starting current required for initially operating the compressor. Thus, the starting current in the electrical appliance becomes higher than the set value. As a result of the previous regulation, a plurality of low-capacity compressors have recently been applied rather than large-capacity compressors.

However, even if a plurality of compressors are used in the outdoor unit for the air conditioner of the front suction type as described above, the compressors are sufficiently connected between the various internal components and the refrigerant piping because the compressors are more complicatedly connected to each other by the condenser, the accumulator and the refrigerant piping. Since there is no space for inserting a tool for disassembling, it is difficult to disassemble the compressors, and thus there is a problem in that the compressors cannot be easily repaired and inspected.

The present invention has been made to solve the above-described problems of the prior art, even if a plurality of compressors are included can be installed with a predetermined space with other components, so that the compressors can be easily removed to facilitate repair and inspection It is an object of the present invention to provide a compressor installation structure of an outdoor unit for an air conditioner of a front suction discharge type.
