Title:
ガス気化システム
Document Type and Number:
Japanese Patent JP7209965
Kind Code:
B2
Abstract:
To provide a gas vaporization system using a heat pump system.SOLUTION: A gas vaporization system 1 comprises an underground heat exchanger 11, a water-air heat exchange unit 12, a heat pump device 13, a first flow passage 21, a second flow passage 22, a third flow passage 23, and a first motor-operated valve 31. The first flow passage 21 connects the underground heat exchanger 11 and the water-air heat exchange unit 12. The second flow passage 22 connects the water-air heat exchange unit 12 and the heat pump device 13. The third flow passage 23 connects underground heat exchanger 11 and the heat pump device 13. The first motor-operated valve 31 switches between a case where first liquid 81 is passed to the water-air heat exchange unit 12 from the underground heat exchanger 11 via the first flow passage 21, and a case where the first liquid 81 is passed to the heat pump device 13 from the underground heat exchanger 11 via the third flow passage 23.SELECTED DRAWING: Figure 1
