Abstract
A refrigeration device includes a compressor, a condenser, an expansion valve, an evaporator, intake electromagnetic valves and exhaust electromagnetic valves, two-position three-way electromagnetic valves or two-position five-way electromagnetic valves, a cylinder group, a volume-variable airproof container, two-position two-way electromagnetic valves and a generator. The cylinder group is composed of two or more cylinders, refrigerant flows successively through the compressor, the intake electromagnetic valves, the cylinder group, the exhaust electromagnetic valves, the condenser, the expansion valve and the evaporator and finally enters the compressor from the evaporator, the cylinder group can do work to generate electricity through atmospheric pressure in the volume-variable airproof container and compensates for electric energy consumed by the compressor, and therefore the electric energy can be saved.
