PURPOSE:To increase the reliability of a cooling system, to prolong the life of the title transformer as well as to reduce the suspension of operation of the transformer by a method wherein an air pump. That works as a refrigerant circulating pump as well as compressed air in the circulating system of a cooling system. CONSTITUTION:An air pump 20 having compressed air as the source of power, an air pipe 21 wherein compressed air which is the source of power of a refrigerant circulating pump is passed through, and a compressor 22 which produces compressed air are provided, and the power sources of the compressor 22 and a condenser are formed independently. Consequently, as an auxiliary pump is provided on the compressor, the air pump 20 does not stop immediately even when the pump of the compressor 22 stops by the suspension of electric power of the auxiliary power source. As a transformer can be stopped while its load value and heating power are being reduced without stopping the transformer immediately, the thermal deterioration of the insulator can be prevented. Also, as the compressor 22 and the condenser are formed on separate system, thermal breakdown is not generated on the transformer immediately even when either of the power source is in trouble, and as the condenser and the refrigerant circulating pump have the independent source of power for electricity and air, the reliability of the title transformer can be enhanced. |
