When the piston hits the point of maximum downard displacement, it compresses the refrigerant on the upstroke. Not only do these more complex systems reduce refrigerant charge, they also promise improved energy efficiencies and lower GWP potential. These compressors can consist of one vane, which is placed in the body, and sealed against the rotor, or multivane rotary, with vanes located in the rotor.
