- 230000006837 decompression Effects 0.000 description 1
Description
一方、圧力Ｐ１が目標圧力より低い場合には（Ｓ４１でＮＯかつＳ４３でＹＥＳ）、制御装置１００は、第２膨張弁４０の開度を増加させる（Ｓ４４）。これによって、第２膨張弁４０による減圧量が減るので、圧力Ｐ１は上昇する。 On the other hand, when the pressure P1 is lower than the target pressure (NO in S41 and YES in S43), the control device 100 increases the opening degree of the second expansion valve 40 (S44). As a result, the amount of decompression by the second expansion valve 40 is reduced, so that the pressure P1 rises.
