PURPOSE: To improve the safety and reliability by correctly detecting temperature inside a high pressure chamber of a sealed container to which a compressed refrigerant gas is discharged.
CONSTITUTION: A compressed refrigerant gas is discharged through 4 discharge port 4 into a high pressure chamber 1A of a sealed container 1. A temperature- detecting device 10 for detecting temperature of the refrigerant gas is set in the high pressure chamber 1A. The temperature-detecting device 10 consists of pipe members 12 and 13 comprising a front temperature-detecting part 10a having a built-in temperature sensor 11 and an introduction part 10b forming a wiring passage for the temperature sensor 11 respectively. The pipe members 12 and 13 are brought into the high pressure chamber 1A from the outside of the sealed container 1. The pipe members 12 and 13 are formed out of different materials so that a thermal conductivity of the pipe member 12 of the temperature-detecting part 10a is higher than the pipe member 13 of the introduction part 10b.
