A refrigeration device comprises a compressor (1), a condenser (2), an expansion valve, an evaporator (4), air suction solenoid valves (5, 6), exhaust solenoid valves (7, 8), a two-position three-way or two-position five-way electromagnetic valve, a cylinder group, a volume-variable sealed container (11), a two-position two-way electromagnetic valve and a generator. The cylinder group is composed of two or more cylinders (9, 10). Refrigerant flows successively through the compressor (1), the air suction solenoid valves (5, 6), the cylinder group, the exhaust solenoid valves (7, 8), the condenser (2), the expansion valve, the evaporator (4) and finally enters the compressor (1) from the evaporator (4). The cylinder group can do work to generate electricity through atmospheric pressure in the volume-variable sealed container (11) and compensate for electric energy consumed by the compressor (1); therefore, the electric energy can be saved. |
