Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention covers a compression device, more specifically, a compressor body containing a compression element, with a heat storage container filled with a heat storage agent, and the heat storage agent is discharged from the compressor body. The present invention relates to a compression device that stores the heat generated and uses it for defrosting operations, etc.

(Prior Art) Conventionally, this type of compression device is disclosed in, for example, Japanese Patent Application Laid-Open No.
As described in Japanese Patent No. 26465 and as shown in FIG. A heat storage heat exchanger E having a plurality of fins F in an annular shape is disposed in the storage chamber S.

(Problem to be solved by the invention) By the way, when attaching the accumulator to the side of the heat storage container T in which the compressor main body C is installed, it is necessary to attach the accumulator to the compressor main body C. During operation of C, the vibrations were transmitted to the accumulator side and generated large operating noise.

The present invention was made in view of the above-mentioned problems, and its purpose is to provide a compression device that has a simple structure and can reduce operating noise.

(Means for Solving the Problem) In order to achieve the above object, in the present invention, the compressor body 1 containing the compression element CF is covered with a heat storage container 2 filled with a heat storage agent. In a compression device configured to store released heat, an accumulator 5 connected to the suction side of the compression element CF is attached to the side of the compressor body 1, and the heat storage container 2 is attached together with the compressor body 1. It is characterized by being stored inside.

When installing the accumulator 5, the outlet pipe 7 is fixedly supported on the compressor main body 1, the inlet pipe 6 is fixedly supported on the heat storage container 2, and the body outer peripheral wall 51a of the accumulator 5 is fixedly supported. is brought close to the inner wall 21c of the heat storage container 2.

(Function) Since the compressor main body 1 and the accumulator 5 are housed together with the heat storage container 2 loaded with a heat storage agent, noise due to vibration etc. is less transmitted to the outside, and operational noise is reduced. It is.

Further, an outlet pipe 7 extending from the accumulator 5 is connected to the compressor main body 1, and an inlet pipe 6 is connected to the heat storage container 2.
and the body outer peripheral wall 51a of the accumulator 5 is fixed to the inner wall 21c of the heat storage container 2.
When installing the accumulator 5 in close proximity to the compressor main body 1, use a paraffin-based heat storage agent with a relatively low melting point as the heat storage agent loaded into the heat storage container 2, and move this heat storage agent away from the compressor body 1. By keeping the heat storage agent in a solid state between the body outer circumferential wall 51a of the accumulator 5 and the inner wall 21c of the heat storage container 2, which are not easily affected by heat, the heat storage agent in the solid state and the compressor of the outlet pipe 7 are The connecting portion to the main body 1 and the heat storage container 2 of the inlet pipe 6
