WALL SPLIT AIR CONDITIONER Russian patent published in 2015 - IPC F24D15/04 

FIELD: ventilation.

SUBSTANCE: wall split air conditioner has a binary compressor consisting of an electric motor with a shaft and mechanical transmissions installed on its ends in the form of crankshafts, a piston compressor and a pneumatic actuator with a possibility of operation in anti-phase mode, and bypass valve system which is implemented in the form of cylindrical housing electric motor installed on a shaft with the bypass branch pipes rowed on its surface and along the longitudinal axis, one of end branch pipes is interconnected with the heating air heat exchanger, another end one - with the cooling air heat exchanger, and the middle branch pipe is interconnected with the pneumatic actuator. On the electric motor shaft the bushing is installed with a possibility of rotation which has cross grooves arranged symmetrically with reference to the longitudinal axis of the bushing and shifted with reference to each other with a possibility of bypass of working reagent for providing of operation of the piston compressor and the pneumatic actuator in anti-phase mode.

EFFECT: consumption decrease and design simplification.
