PROBLEM TO BE SOLVED: To provide a compact stirling cold energy supply system 1 easy in its air vent. SOLUTION: A working gas-side heat exchanger 35 is built in a stirling refrigerating machine 4, two such stirling refrigerating machines 4 are prepared and accompanying this, two radiators 65 are also mounted. The cooling water is allowed to flow successively in a first radiator 65a, a first working gas-side heat exchanger 35a, a second radiator 65a, a second working gas-side heat exchanger 35a, and a cooling water pump 67. An air vent tube 85 is mounted on a position of the maximum difference in height in the cooling water circuit to release the air in the cooling water circuit, when the cooling water is charged into the cooling water circuit to be utilized, and an air vent valve 79 is mounted on its end part.
