除去が重要な問題となる。If a large amount of water is present in the refrigerant circulation system of the refrigeration system, the water in the circulation freezes in the low temperature portion of 0 ° C. or lower, blocking the refrigerant circulation system, resulting in insufficient refrigerating capacity and seizure of the compressor. To do. Further, a large amount of water may react with the refrigerating machine oil to accelerate the deterioration of the oil. In particular,
In the case of a new refrigerant that is being developed as a control measure for specific CFCs, there is the fact that ester refrigerating machine oil that is compatible with the new refrigerant is easily hydrolyzed, and removal of water from the refrigerant circulation system is an important issue. Become.
【０００５】上記のような事情から上記した冷媒回路に

目的から水分を吸着する乾燥剤粒子を充填した冷媒乾燥
装置が設けられることとなっている。Under the circumstances as described above, as in the refrigerant circuit described above, a refrigerant drying device filled with desiccant particles that adsorb water is provided for the purpose of removing the water mixed in the refrigerant circulation system. There is.

知られている。As the above-mentioned refrigerant drying apparatus, as disclosed in Japanese Utility Model Publication No. 60-32537, the inside of a main body case having a refrigerant inlet at one end and a refrigerant outlet at the other end is dried inside. It is known that a desiccant-filled container filled with agent particles and having a large number of refrigerant circulation holes is arranged.

【発明が解決しようとする課題】ところで、上記のよう
な構成の冷媒乾燥装置の場合、水分吸着のためには乾燥

ざるを得ないため、加圧蓋による加圧力が乾燥剤粒子全
体に付与されにくく、乾燥剤粒子相互のこすれあいを完
全に防止できないという問題がある。By the way, in the case of the refrigerant drying apparatus having the above-mentioned structure, it is necessary to bring the desiccant particles filled in the desiccant-filled container into contact with the refrigerant in order to adsorb water. Therefore, the refrigerant flows through the desiccant particles. Therefore, vibration may occur due to the collision between the refrigerant and the desiccant particles, and the desiccant particles may rub against each other to be pulverized. In order to prevent this, as disclosed in the above-mentioned known example, a device for suppressing rubbing between desiccant particles by providing a pressure lid for compressing the desiccant particles in the desiccant-filled container has been proposed. However, in order to secure the contact area between the desiccant particles and the refrigerant, the desiccant filling container must be lengthened in the pressing direction by the pressure lid, so the pressure applied by the pressure lid is dried. There is a problem that it is difficult to be applied to the whole of the agent particles and rubbing between the agent particles cannot be completely prevented.

うにしたものも提案されている(例えば、実開平４ー５
７１７１号公報参照)。Further, the refrigerant drying apparatus completely adsorbs and removes the water initially mixed in the refrigerant circulation system within a predetermined period (for example, about 100 hours) from the start of operation of the refrigerating apparatus. It has also been proposed that a desiccant particle is prevented from being pulverized by providing a refrigerant passage bypassing the device (for example, actual Kaihei 4-5).
7171).

の別途配管および稼動開始から所定期間バイパス通路側

操作が必要となるという問題もある。However, in the case of the known technique, not only a separate pipe for bypass and a valve for preventing the refrigerant from flowing to the bypass passage side for a predetermined period from the start of operation are required, but also a new refrigerant is charged. There is also a problem that valve operation is required in some cases.
