Title:
PRE-COOLER OF HYDROGEN GAS FILLING FACILITY AND PRE-COOLING METHOD
Document Type and Number:
Japanese Patent JP2017067178
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To keep a cooling temperature constant where hydrogen gas is cooled even if its configuration is simplified and its energy saving is carried out.SOLUTION: This invention relates to a pre-cooler 21 of hydrogen gas filling facility for cooling hydrogen gas prior to its filling where there is provided a refrigerant circulation passage 22 having liquid refrigerant R having a boiling point under a specified pressure as a temperature suitable for a cooling temperature of hydrogen gas filled in sealed state therein. A heat exchanging part 23 for evaporating refrigerant is provided in a liquid phase portion Ra of the refrigerant R in the refrigerant circulation passage 22 to cool the hydrogen gas through heat exchanging between the hydrogen gas to be cooled and the liquid-phase-refrigerant R to be evaporated. A heat exchanging part 24 for condensing refrigerant is provided in a gaseous phase portion Rb of the refrigerant R in the refrigerant circulation passage 22 to condense the gaseous-phase-refrigerant R through heat exchanging with the liquefied hydrogen. In addition, there is provided pressure adjustment means 29 for adjusting a pressure of refrigerant R in the refrigerant circulation passage 22 to a prescribed specific pressure to keep a temperature of the refrigerant R constant.SELECTED DRAWING: Figure 1
