を冷却してコールドボックス２に戻る。To explain the operation of the refrigerator, the refrigerant gas compressed by the compressor 1al is led to the cold box 2, and is cooled by the return of the cold through the heat exchangers 5 and 9~[while a part of the compressed refrigerant gas is enters the expansion turbine 7.8 via the expansion turbine artificial valve 6, generates cold by adiabatic expansion, and joins the cold return line. The compressed refrigerant gas finally expands at the JT valve B, cools the object to be cooled, and returns to the cold box 2.

なっており、水分。In the above refrigerator, compression I! The refrigerant gas compressed by 1 adsorbs impurities (moisture, oil, etc.) in the adsorption cylinder 3. The adsorption cylinder 3 is maintained at a low temperature by guiding a portion of the low-temperature cold return through the adsorption cylinder cooling gas supply valve 4, which has the effect of improving the adsorption capacity. The adsorption cylinder 3 has a structure that allows it to be easily taken out using the joints 14a to 14d.

．． The expansion turbine artificial valve s, the JT valve port, the adsorption cylinder cooling gas supply 5'F4, and the valve 17 are closed to stop the refrigerant gas. Desirably, the inside of the cold box 2 is evacuated to a vacuum by an exhaust device (not shown).

吸着筒３に導入された圧縮機ｌからの高圧の冷媒ガスは
、吸着筒３で不純物を除去されるとともに冷却される。Furthermore, although the adsorption tube 3 is cooled by using the refrigeration of the return refrigerant gas, there is no heat loss in the refrigerator as a whole. That is, although not shown, the heat exchanger 5 is precooled by LN2, and the return refrigerant gas is cooled as well as the compressor l.
It is designed to cool high-pressure refrigerant gas from. Therefore, if a portion of the return refrigerant on the upstream side of the heat exchanger 5 is used for cooling the adsorption column 3'I), the high-pressure refrigerant gas will not be sufficiently precooled. However, the high-pressure refrigerant gas from the compressor 1 introduced into the adsorption column 3 cooled in this manner is cooled while removing impurities therein.
冷却された高圧の冷媒ガスは、冷却されたまま熱交換器
５へ送られるので、予冷のための寒冷は少なくてすむ。Since the cooled high-pressure refrigerant gas is sent to the heat exchanger 5 while being cooled, less refrigeration is required for pre-cooling.
このように、吸着筒３を冷却するのに用いられた寒冷は
、高圧の冷媒ガスの予冷で回収されるので熱ロスがない
。In this way, the cold water used to cool the adsorption column 3 is recovered by pre-cooling the high-pressure refrigerant gas, so there is no heat loss.

This figure differs from Figure 1 in that the vacuum cold storage tank is provided independently from the cold box 2, and is evacuated to a vacuum by an exhaust device (not shown). This is because a suction cylinder 3 is provided inside. In addition, the joints 14m and 14b of the suction cylinder 3
