Abstract
A refrigerating system is provided in which a heat exchanging unit performs heat exchange between first and second evaporators, so that the first and second evaporators have similar temperatures, and so that an additional 'pump-down' operation may be avoided, thereby reducing compressor losses due to discharge occurrences. Since the additional pump-down operation may be avoided, power consumption may be reduced, and reliability and efficiency of the system may be enhanced. Additionally, a backflow preventing unit for preventing backflow of refrigerant in an evaporator may not be required, thus further reducing fabrication cost and complexity.
