Abstract
A refrigerating apparatus employs a mixture of coolants and a coolant controller for controlling a ratio between the coolants to adjust refrigerating capacity during a refrigerating operation. The apparatus has a compressor whose revolution speed is controlled to provide required refrigerating capacity. When the revolution speed of the compressor decreases below a lower set value or rises above an upper set value, the coolant controller controls the ratio between the coolants.
