Abstract

PURPOSE:To establish storing for the cold energy thrown away till now as the fluid medium of normal temperature and high pressure by storing the medi um liquidized by cold energy of low temperature, liquidized gas in the fluid condition of normal temperature and high pressure to use it at the desired time. CONSTITUTION:The gas medium of normal temperature and low pressure sup plied from a gas holder 1 is changed by a cold energy exchanger 2 to the fluid condition of low temperature and low pressure to store it in a receiver tank 3. The pressure of the store liquidized medium is increased by a pump 4 and then the temperature of the medium is raised by a heat exchanger 5, therefore the medium is changed to the fluid condition of normal temperature and high pressure. The fluid medium is temporarily stored at normal temperature and high pressure in a medium store tank 6. The medium is optionally taken out in response to the request from the load side and is expanded by an expansion valve 7 to the low temperature and low pressure condition, consequently the cold energy can be supplied to the load 8 such as a freezing warehouse, etc.
