A refrigerating system is disclosed. Since heat exchange is performed between first and second evaporators by a heat exchanging unit, the first and second evaporators have temperatures similar to each other, thereby requiring no additional‘pump-down’operation. Also, a compressor does not have a discharge occurrence owing to no additional‘pump-down’operation, thereby having no loss and an enhanced reliability. Besides, since no additional pump-down operation is required, power consumption for operating the compressor so as to collect a remaining refrigerant is reduced. Accordingly, the efficiency of the refrigerating system is enhanced. Furthermore, as the‘pump-down’operation is not required, a backflow preventing unit for preventing a refrigerant collected from an evaporator from backflowing to the evaporator is not required. Accordingly, the fabrication cost is reduced.
