Description

Packaged Compressor {PACKAGED COMPRESSOR}

The present invention relates to a packaged compressor containing a compressor body for compressing fluid in a soundproof box.

In general, the packaged compressor is roughly composed of a soundproof box surrounded by a front plate, a rear plate, left and right side plates, a bottom plate and an upper surface plate, and a compressor body installed in the soundproof box to compress the fluid. Noise generated when the operation can be reduced by the soundproof box.

By the way, this type of package type | mold compressor is normally made to cool the compressor main body by the cold air which distribute | circulates in a soundproof box, to suppress the temperature rise in a soundproof box, and to improve durability of the motor etc. which drive a compressor main body. For this reason, the intake duct and the exhaust duct for distributing a large amount of cold air in the said soundproof box are provided in the soundproof box (for example, Unexamined-Japanese-Patent No. 3-164583 etc.).

However, since the intake duct and the exhaust duct are provided on the rear plate constituting the soundproof box so as to protrude rearward, the package compressor of the prior art is enlarged, and the installation space of the packaged compressor is increased. There is a problem that is thrown away.

On the other hand, as another prior art, a packaged compressor is known in which an intake duct and an exhaust duct are formed in a soundproof box so that the compressor main body can be cooled efficiently by a large amount of cold wind, and the installation space can be limited small. have.

Therefore, the above-described packaged compressor according to the related art will be described with reference to FIG.

In the drawing, reference numeral 101 denotes a soundproof box, and the soundproof box 101 is a front plate 102, a rear plate 103, a left side plate 104, a right side plate 105, a bottom plate 106, and an upper side plate ( It is formed in the box shape of the rectangular parallelepiped surrounded by 107).

Reference numeral 108 denotes a first partition plate installed in the soundproof box 101, and the partition plate 108 extends from the bottom plate 106 to the top plate 107 while facing the rear plate 103. Extend in the direction. Reference numeral 109 denotes a second partition plate provided between the rear plate 103 and the partition plate 108, and the partition plate 109 is located at the center of the left and right directions of the rear plate 103 and the partition plate 108. It extends in the up-down direction from the bottom plate 106 to the upper surface plate 107.

As a result, the intake duct 110 and the exhaust duct 111, which are partitioned left and right by the partition plate 109, are formed between the rear plate 103 and the partition plate 108. On the other hand, an accommodation space 112 is formed between the front plate 102 and the partition plate 108 to accommodate a compressor main body (not shown).

In addition, the partition plate 108 is provided with a cold air inlet 108A for opening to the intake duct 110 and a cold air outlet 108B for opening to the exhaust duct 111. In addition, the right side plate 105 is formed with an intake port 105A opening to the intake duct 110, and the upper side plate 107 is formed with an exhaust port 107A opening to the exhaust duct 111.

When the cooling fan (not shown) rotates during the operation of the compressor main body, cold air is sucked into the intake duct 110 at the inlet port 105A of the right side plate 105, as shown by arrow A of FIG. Thereafter, it is introduced into the accommodation space 112 through the cold air inlet 108A of the partition plate 108. The cold air introduced into the accommodation space 112 cools the compressor main body, etc. in the accommodation space 112, and then is led into the exhaust duct 109 at the cold air outlet 108B of the partition plate 108, and the upper portion thereof is cooled. It is the structure discharged | emitted to the exterior through the exhaust port 107A of the face plate 107.

Some recent packaged compressors have an inverter device that can easily control a motor. The inverter device is attached to a soundproof box in a state accommodated in an inverter accommodating box.

However, in the above-described packaged compressor according to the related art, the intake duct 110 and the exhaust duct 111 partitioned by the partition plate 109 between the rear plate 103 and the partition plate 108 are left and right. The side inlet is formed side by side, so that the inlet port 105A is provided only on the right side plate 105 positioned on the intake duct 110 side, and the left half located on the exhaust duct 111 side of the upper side plate 107. Only the exhaust port 107A is provided.

For this reason, there is a problem that the opening area of the exhaust port 107A is limited to be small, and sufficient cold air cannot be flowed into the soundproof box 101, and the compressor main body and the like cannot be cooled efficiently.

In addition, since the inlet port 105A is provided only in the right side plate 105, when the packaged compressor is installed in a building such as a factory, it is necessary to separate the right side plate 105 provided with the inlet port 105A from the wall of the building. There is a problem that the installation place of the packaged compressor in a building is limited.

On the other hand, a packaged compressor in which an intake duct and an exhaust duct are formed in a soundproof box generally increases the opening area of the inlet and the exhaust port so that a large amount of cold air can be distributed in the soundproof box, thereby efficiently cooling the compressor main body and the like.

However, when the opening area of the intake port or the exhaust port is enlarged, there is a problem that noise generated from the compressor main body is likely to leak to the outside through the intake port or the exhaust port, and the working environment around the package compressor is deteriorated.

Moreover, in the package compressor by the prior art provided with an inverter device, the inverter accommodating box which integrated the inverter device is arrange | positioned in a soundproof box. However, since an inverter device is comprised by electrical components, such as a switching element, it generates heat at the time of operation. For this reason, when the inverter device (inverter accommodating box) is accommodated in a soundproof box that is easy to heat, there is a problem that the inverter device cannot be sufficiently cooled and the temperature of the inverter device rises above the set reference value. In this case, when the temperature of the inverter device rises, the temperature of the capacitor in the inverter device rises, and the capacitor changes characteristics significantly due to temperature change (for example, the life of the capacitor is halved every time the ambient temperature rises by 10 ° C). box).
