Abstract

PURPOSE:To reduce noise by attaching a cushioning material and a coating material to the compressor in a compressor unit which is independent of a main body, and a sound proof material between a first frame and a second frame so as to place the compressor in the closed state. CONSTITUTION:In a compressor unit 20 provided independently of a main body 3, a first frame 21 which can be dissembled is formed, and at a bottom part 22 of its frame 21, a cushioning material 23 and a base plate 24 fixed to it with an adhesive are constituted integrally. A compressor 26 is provided on this base plate 24 with a vibration isolator 25 interposed. This compressor 26 is entirely coated by a coating material 27. A sound proof material 28 is stuck to the outside of the frame 21, and a protrusion part 29 appropriately formed in the protruded state is provided over the whole circumference. In the meantime, a vibration proof material 31 is stuck to a second frame 30, which is constituted through engagement with the sound proof material 28 to provide a sound and a vibration proof effects. By this, most of the noise generated by operation of the compressor is absorbed and leakage of noise can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to noise reduction of individual air conditioners installed in the perimeter zone of a building.

2. Description of the Related Art Conventionally, this type of individual air conditioner is as shown in Fig. 3.
A main body 3 of the air conditioner is provided below the window 1 of the building with a chamber unit 2 interposed therebetween, and inside the main body 3 there are an outdoor unit part 4, a total heat exchange unit part 5,
It is composed of an indoor unit section 6. The outdoor unit section 4 is equipped with an outdoor blower 7 and an outdoor heat exchanger 8, and has a flow path shown by an arrow BC that sucks outside air and passes through the outdoor heat exchanger 8 as shown by an arrow A, and a flow path shown by an arrow mark. A duct 9 is provided as an air supply path to communicate with the total heat exchange unit 5. On the other hand, the indoor unit section 6 sucks indoor air as shown by arrow E, passes through a filter 10, passes through an indoor blower 11, passes through an indoor heat exchanger 12, and blows out indoors from an indoor air outlet 13. . Further, a compressor 14 is mounted on the side of the indoor unit section 6,
When the compressor 12 is operated, the areas that make a lot of noise are covered with a covering material 5 made of felt material to reduce noise when the compressor 14 is operated.

Problems to be Solved by the Invention In such a conventional compressor covering device, the entire periphery is surrounded by the covering material 15, but the noise is still annoying and the indoor unit part 6. Total heat exchange unit section5. The problem is that the noise is transmitted throughout the outdoor unit section 4 and the main body 3, and the noise level has not yet been satisfactorily reduced.In particular, people who work near the main body 3 find it extremely harsh on the ears. was one of the issues.

The present invention aims to reduce such problems and to reduce the noise caused by compressor operation, which is the largest cause of noise.

Means for Solving the Problems In order to solve the problems, the present invention includes a main body consisting of an outdoor unit section, a total heat exchange unit section, and an indoor unit section, and a compressor unit independent of this main body. , the compressor unit includes a first frame, a base plate integrated with a cushioning material at the bottom of the first frame, and a vibration isolator attached to the base plate to operate the compressor. A sound insulating material having a convex portion formed in an appropriate convex shape is attached to the outer periphery of the first frame, and a second sound insulating material is installed around the compressor. The second frame includes a vibration-proofing material that fits between the second frame and the sound-proofing material.

Effect: With this configuration, the sound when the compressor is operated is insulated by the covering material, then sound insulated in the first frame, further absorbed by the sound insulating material, and sound is absorbed by the second frame. They fit together with the vibration isolating material and absorb sound, at least most of the noise caused by the operation of the compressor, thereby preventing noise leakage.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. It should be noted that the same numbers as those given in the explanation of the conventional example indicate the same thing, and the explanation will be omitted.

That is, the main body 3 includes an outdoor unit 4, a total heat exchange unit 5. It is composed of an indoor unit 6.

Separately from the main body 3, a compressor unit 20 is installed independently in the same perimeter zone, and a discharge pipe 21 is installed.
and suction pipe 22 are indoor heat exchanger 12. and suction pipe 22, respectively. It is connected to an outdoor heat exchanger 8. As shown in FIG. 1, the compressor unit 20 has a first frame 21 that can be disassembled, and a cushioning material 23 made of hard rubber is attached to the bottom 22 of the first frame 21. The material 23 and a base plate 24 made of sheet metal are fixed together with an adhesive.

A compressor 26 is provided to the base plate 24 with a vibration isolator 25 made of rubber and springs interposed therebetween. The entire circumference of the compressor 26 is covered with a covering material 27 made of felt material. A soundproofing material 28 made of a non-washed rubber sheet with high specific gravity is pasted and attached to the outside of the first frame 21, and a convex portion 29 is formed in a convex shape as appropriate around the entire circumference.
has been established. On the other hand, the second frame 30 is disassembleable, has a vibration-proofing material 31 made of high-density butyl rubber pasted on the inside, and is fitted with the sound-proofing material 28 to achieve a soundproofing effect and a soundproofing effect. This is to create a vibration effect. A discharge pipe 32 and a suction pipe 33 are led out from the compressor 26 to form a heat pump type refrigeration cycle, and are sealed with a bushing 34 so that there is no gap in the first frame 21.

In the above configuration, the compressor unit 20 is provided as a separate unit from the main body 3. Therefore, the refrigerant pipes, that is, the discharge pipe 32 and the suction pipe 33, are routed along the inside of the peri-counter to the indoor heat exchanger 13. It is connected to an outdoor heat exchanger 8, etc., to configure a heat pump type refrigeration cycle. Therefore, the compressor 26. The air is conditioned by operating the indoor blower 11° and the outdoor blower 7, but the sound generated from the compressor 26 is below the
The buffer material 23 absorbs primary sound, and the covering material 23 above absorbs primary sound. Next, secondary sound is absorbed by the sound insulating material 28 pasted on the first frame 21 and the vibration isolating material 31 pasted on the second frame 30. That is, the compressor 26 includes the covering material 27 and the cushioning material 23,
Most of the sound and vibrations are absorbed by the sound insulating material 28 and the vibration isolating material 31 between the first frame 21 and the second frame 30 in a sealed state. Moreover, the compressor unit 20
Since it is constructed as an independent and separate unit, it will never propagate to the main body 3 provided in the perimeter zone.

Effects of the Invention As is clear from the description of the above embodiments, the present invention comprises an independent compressor unit separate from the main body, and the compressor in this compressor unit is provided with a cushioning material, a covering material, and a first frame. Since the compressor is sealed by installing soundproofing material between the body and the second frame, most of the operating noise generated by the compressor is eliminated and does not propagate to the main body, reducing noise. This eliminates harsh noises that may bother you even in a quiet room. This has the effect that even people who work near the main body of the air conditioner will not feel any harsh noise.
