本発明は冷凍サイクル用ドライヤーに係り、特に吸湿剤
の摩滅防止に好適な冷凍サイクル用ドライヤーに関する
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dryer for a refrigeration cycle, and more particularly to a dryer for a refrigeration cycle suitable for preventing abrasion of a moisture absorbent.
一般に冷凍サイクル系統に挿入するドライヤーは、円筒
状の本体内を一定間隔で仕切り、その空間に吸湿剤を充
填し構成されているが、振動や冷媒流で吸湿剤が踊り、
粒子同志の摩擦によって吸湿剤が摩滅し、硬質な微細粉
末を生じる。この微細粉末が圧縮機の摺動部に入り込み
、圧縮機の異常摩耗の原因となるという欠点があワた。Generally, a dryer inserted into a refrigeration cycle system is constructed by dividing a cylindrical body at regular intervals and filling the spaces with a moisture absorbent, but the moisture absorbent dances due to vibrations and refrigerant flow.
The moisture absorbent is worn away by the friction between the particles, producing a hard, fine powder. The disadvantage was that this fine powder entered the sliding parts of the compressor and caused abnormal wear of the compressor.
吸湿剤の摩滅を防止するものとしては実公昭６０−３２
５３７号公報に示されるように、吸湿剤充填部の前方に
整流板を設は冷媒の渦流発生を防ぎ、後方から吸湿剤を
スプリングで押えて踊りを防止するものが知られている
。As a method to prevent moisture absorbent from being worn out, the Utility Model Act 1986-32
As shown in Japanese Patent No. 537, it is known that a rectifying plate is provided in front of the moisture absorbent filling part to prevent the generation of a vortex flow of the refrigerant, and the moisture absorbent is pressed from behind by a spring to prevent dancing.
上記従来技術は、吸湿剤の粒子径にはバラツキがあり、
大きな粒子の集団に小さな粒子が入ると槁かけ状態とな
り、スプリングで押えても大きな粒子の間で小さな粒子
が踊り、吸湿剤の摩滅が発生する恐れがあった。In the above conventional technology, the particle size of the moisture absorbent varies;
When a small particle enters a group of large particles, it becomes jammed, and even when pressed with a spring, the small particles dance among the large particles, which may cause wear and tear on the moisture absorbent.
本発明の目的は吸湿剤粒子が硬質な摩耗粉を生じない冷
凍サイクル用ドライヤーを提供することにある。An object of the present invention is to provide a dryer for a refrigeration cycle in which the moisture absorbent particles do not produce hard abrasion powder.
上記目的は、冷媒流入口と冷媒流出口を有する容器の外
殼の中に、一定間隔を設けて複数の微少貫通穴を設けた
仕切板と半球状の金網を配置固定して、仕切板と金網と

ティングすることにより達成される。The above purpose is to arrange and fix a partition plate with a plurality of minute through holes at regular intervals and a hemispherical wire mesh in the outer shell of a container having a refrigerant inlet and a refrigerant outlet. This is achieved by coating the surface of the moisture absorbent with a moisture-permeable polymer in a refrigeration cycle dryer in which a moisture absorbent is filled in the space between the moisture absorbent and the moisture absorbent.
吸湿剤粒子の表面にコーティングした透湿性ポリマーが
吸湿剤の保護膜となり、吸湿剤同志が直接接触すること
がな（なるので、圧縮機の異常摩耗の原因となる吸湿剤
の摩耗粉が発生することがない。The moisture permeable polymer coated on the surface of the moisture absorbent particles acts as a protective film for the moisture absorbent, preventing the moisture absorbents from coming into direct contact with each other. Never.

Figure 2 is a cross-sectional view of the dryer of the present invention, Figure 2 is a cross-sectional view of the adsorbent in the dryer, Figure 3 is a refrigeration cycle system diagram equipped with the dryer of the present invention, and arrows indicate the flow of refrigerant. This shows that.

る。The refrigeration cycle includes a compressor 7, a condenser 8, a dryer 1,
A partition plate 2 consisting of a capillary tube 6, an evaporator 9, and an accumulator, and a hemispherical wire mesh 3 are fixed at regular intervals on the refrigerant outflow side, and the space between the partition plate 2 and the wire mesh 3 is a moisture absorption device coated with a moisture-permeable polymer. Agent 4 is filled.

湿剤４ａの摩滅粉による圧縮機７の摺動部異常摩耗が防
止できる。The refrigerant circulating in the refrigeration cycle enters the dryer 1 from the piping 5 and reaches the capillary tube 6, but the moisture in the refrigerant easily passes through the moisture permeable polymer layer 4b coated on the surface of the moisture absorbent 4a. It is removed by adsorption. Furthermore, even if the moisture absorbent 4 dances due to the refrigerant flow or the vibration of the compressor 7, it will cause friction between the flexible moisture permeable polymer layers 4b. Fine abrasion powder is no longer generated. Therefore, abnormal wear of the sliding portion of the compressor 7 due to the abrasion powder of the moisture absorbent 4a can be prevented.
また、吸湿剤に透湿性ポリマーをコーティングするだけ
で摩耗粉の発生を防止できるので、ドライヤーの製造が
安価にできる。Furthermore, simply coating the moisture absorbent with a moisture permeable polymer can prevent the generation of abrasion powder, so the dryer can be manufactured at low cost.

生を防げるので圧縮機摺動部の摩耗防止に効果かある。According to the present invention, it is possible to prevent the generation of hard fine powder due to wear of the moisture absorbent, which is effective in preventing wear of the sliding parts of the compressor.
