Claims

[Scope of utility model registration request]

A refrigerant evaporator and multiple series circuits of electromagnetic valves are installed in parallel in a cooling circuit with a refrigerant compressor, and a blower for blowing cold air is installed corresponding to each refrigerant evaporator, making it compatible with any blower. In a multi-stage vehicle cooling system, the refrigerant evaporators are selectively brought into operation, and the opening and closing of the corresponding electromagnetic valve is controlled by the output of a temperature switch provided corresponding to each refrigerant evaporator. A variable capacity compressor whose compression capacity can be changed by opening and closing a valve is used as the refrigerant compressor, and the variable capacity compression is performed according to a predetermined combination of outputs of temperature switches corresponding to each of the refrigerant evaporators. A multi-stage axle cooling system characterized by controlling the opening and closing of the machine's valves.
