PURPOSE: A refrigerating system for a refrigerator car is provided to improve energy efficiency and reduce the volume of a refrigerating system. CONSTITUTION: A refrigerating system for a refrigerator car comprises a generator(13), a battery charger(15), a DC motor(21), a compressor(23), a condensation generator(25), an evaporator(37), and a refrigerating unit(20). The generator is driven by an automobile engine and an engine. The battery charger stores electricity produced by the generator. The DC motor is driven by the electricity of the battery charger. The compressor is driven by the DC motor and compresses refrigerant. The condensation generator generates power using the kinetic energy of the refrigerant compressed by the compressor and condensates the refrigerant compressed by the compressor, simultaneously. The evaporator heat-exchanges the refrigerant condensed by the condensation generator to cool the inside of a freezer The refrigerating unit comprises the DC motor, the compressor, and the condensation generator and is installed on the front top of the refrigerator car. |
