PURPOSE:To enable to lower the discharge pressure of a compressor, by utilizing cold liquefied gas stored in a cold liquefied gas storing tank as coolant in a condenser, and thereby lowering the condensation temperature. CONSTITUTION:Compressed, vaporized gas carried to a condenser 24 is cooled by cold liquefied gas and condensed into liquid by the condenser 24. The liquefied gas is carried via a liquefied gas passage 26 back to a cold liquefied gas storing tank 21, and at the same time, liquefied gas supplied to the condenser 24 and heated to a normal temperature while passing through the condenser 24 is carried to a normal- temperature liquefied gas storing tank 30 via a normal-temperature liquefied gas passage 29. By thus utilizing cold liquefied gas as coolant in the condenser 24, it is enabled to lower the condensation temperature and to lower the discharge pressure of a compressor 22. |
