PURPOSE:To aim at reduction in engine load and uniformization in refrigerant pressure, by performing the drive of a refrigerant compressor with an electric motor, driving it by the electrical energy recovered from exhaust energy, and making it so as to install a current controlling device in a current feed route. CONSTITUTION:Exhaust gas out of five-cycle engine is fed to an exhaust gas turbine 8, rotating this turbine 8 with potential heat of the exhaust gas and pressure energy, and an alternator 9 is driven, thus electrical energy is taken out. At this time, a bypass valve 5 is controlled, keeping exhaust gas pressure to the turbine 8 constant, and thereby the electrical energy is stabilized. This electrical energy taken out is fed to a motor 41 and a refrigerant compressor is driven. At this time, compressor outlet pressure is monitored by a pressure sensor 45, and a current controlling device 46 is controlled, keeping the extent of refrigerant pressure in the specified value. With this constitution, engine load is reduced and, what is more, the refrigerant pressure is keepable constant. |
