PROBLEM TO BE SOLVED: To provide a refrigerating device for transportation capable of suppressing increase in manufacturing cost and controlling heating capacity. SOLUTION: The refrigerating device 1 for land transportation includes: a refrigerating cycle formed by interconnecting at least a compressor 3, a condenser 5, a pressure reducing valve 7 and an evaporator 9 by refrigerant piping 11; and hot gas bypass piping 13 branched from the refrigerant piping 11 on the discharge side of the compressor 3, merged with the refrigerant piping 11 on the upstream side of the evaporator 9 and having a bypass on-off valve 15 for opening/closing the piping. A merging point B of the hot gas bypass piping 13 with the refrigerant piping 11 is positioned on the upstream side of the pressure reducing valve 7. COPYRIGHT: (C)2011,JPO&INPIT |
