As the compressors 150 and 150 ', a scroll compressor having low noise and excellent efficiency is preferably used. In particular, the inverter compressor 150' uses an inverter scroll compressor whose rotation speed is adjusted according to a load capacity. Therefore, when a small number of indoor units (not shown) are used and the load capacity is small, the inverter compressor 150 'is operated first, and the load capacity is gradually increased until the inverter compressor 150' cannot be handled by the inverter compressor 150 '. Constant speed compressor 150 is operated. Of course, as described above, instead of the pair of compressors 150 and 150 ′, only one compressor may be used.

The accumulator 160 is installed on the right side of the barrier 120. That is, the accumulator 160 that filters the liquid refrigerant in the refrigerant flowing into the compressors 150 and 150 'is positioned above the compressors 150 and 150'.

Gas refrigerant flowing from the indoor unit (not shown) enters the accumulator 160. The accumulator 160 filters the liquid refrigerant, and the gas refrigerant passing through the accumulator 160 flows into the compressors 150 and 150 '.

As described above, the compressors 150 and 150 'may use only the inverter compressor 150' or both the constant speed compressor 150 and the inverter compressor 150 'according to the load amount.

The refrigerant discharged from the compressors 150 and 150 ′ flows into the heat exchanger 130. Since the heat exchanger 130 acts as a condenser (in the cooling mode), the refrigerant is cooled through heat exchange with external air to become a liquid refrigerant.

The refrigerant passing through the heat exchanger 130 again flows into an indoor unit (not shown), and the refrigerant introduced into the indoor unit undergoes heat exchange in an indoor heat exchanger that serves as an evaporator, and the refrigerant passing through the indoor heat exchanger again. It flows into the outdoor unit. Through this process, one cycle is completed.

Next, the state in which the accumulator 160 is fixed by the fixing means 200 and 210 will be described.

First, in order to fix the refrigerant pipe 170 using the first fixing means 200, the first fixing means 200 in a state in which the refrigerant pipe 170 is inserted into the pipe accommodating part 204. The fastening part 202 of the close to the barrier 120 is fastened. At this time, a screw is passed through the through hole 202 ′ to be fastened to the barrier 120.

Of course, since the first fixing means 200 may be bent to a certain portion by its elasticity, first, the fastening part 202 is fixed to the barrier 120, and then the coolant to the pipe accommodating part 204. It will be possible to allow the pipe 170 to be inserted.

In addition, the method of directly fixing the accumulator 160 by using the second fixing means 210 will be described. In this case, the second fixing means 210 in the state as shown in FIG. 7 is first fixed to the barrier 120 or the heat exchanger 130. That is, a screw is fastened to the screw fastening hole 222 ′ of the support part 222 so that the support part 222 is tightly fixed to the right end of the heat exchanger 130 or the right side of the barrier 120. do.

Then, while holding the right end (in Fig. 7) of the fixing holder 230 to be bent in a counterclockwise direction (as seen from above), so that the fastening end 232 is in close contact with the fastening surface 226 do. In this case, a screw is connected to the through hole 232 in the state where the through hole 232 ′ of the fastening end 232 and the fastening hole 226 ′ of the fastening surface 226 match each other. ') And the fastening holes 226' are fastened to each other.

In this case, as shown in FIG. 6, the fixing holder 230 surrounds the outer circumferential surface of the accumulator 160, and the support bracket 220 is mounted to the heat exchanger 130 or the barrier 120.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

As described above, in the outdoor unit of the air conditioner according to the present invention, the accumulator is fixed to the barrier or the heat exchanger by separate fixing means. Therefore, there is an advantage that the accumulator connection part is prevented from being broken by vibration during movement of the product (outdoor unit) or operation of the product.

That is, since the accumulator is fixed by the fixing means to reduce the left and right shake, it is prevented that the connecting portions at both ends of the accumulator are damaged by vibration. As a result, according to the present invention, there is an effect that the reliability of the product is improved.
