GROUND FREEZING SYSTEM, AND GROUND FREEZING METHOD
To realize a technology that can derive the optimal pipe length and an appropriate refrigerant flow rate by quantitatively measuring a gas-liquid mixture ratio in a refrigerant returned to a refrigerator side.SOLUTION: A ground freezing system 10 comprises: a freezing pipe 16 cooling surrounding soil 22 with a refrigerant undergoing a gas-liquid phase change; a refrigerator 12 cooling the refrigerant vaporized by heat exchange with the soil 22 to return it to a liquid; third piping 70 circulating the refrigerant between the freezing pipe 16 and the refrigerator 12; and dryness detection means measuring a proportion of gas components in the refrigerant discharged from the freezing pipe 16 and outputting to the outside. The dryness detection means is, for example, a dryness sensor 18.SELECTED DRAWING: Figure 1
【課題】冷凍機側に戻される冷媒中の気液の混合比率を定量的に計測することにより、最適な配管長及び適正な冷媒流量を導出可能とする技術の実現。【解決手段】気液の相変化を伴う冷媒によって周囲の土壌22を冷却する凍結管16と、土壌22との熱交換によって気化された冷媒を冷却して液体に戻す冷凍機12と、凍結管16と冷凍機12との間で冷媒を循環させる第３の配管70と、凍結管16から排出された冷媒中の気体成分の割合を計測し、外部に出力する乾き度検出手段を備えた地盤凍結システム10。乾き度検出手段としては、例えば乾き度センサ18が該当する。【選択図】図１
