Abstract

See full text

A refrigeration apparatus includes a compressor, two or more cylinders coupled with the compressor, and an airproof container enclosing the cylinders and filled with air or other gas. Each cylinder is provided with a piston, an inlet valve coupled with the compressor, and an outlet valve coupled with a condenser. When inlet valves are open, outlet valves are closed, and pistons move from bottom to top of cylinders, refrigerant flows from compressor into cylinders through inlet valves; and when inlet valves are closed and outlet valves are open, refrigerant flows from cylinders into condenser through outlet valves. Then, air pressure in cylinders drops, and pressure in airproof container forces pistons to move to the bottom of cylinders. The pressure in airproof container is utilized by cylinders to produce electrical energy.
