Résumé

A horizontal revolving piston rotary compressor has been integrated radially with a motor- generator and axially- with a heat exchange element/ cooling fans assembly to form a compact air conditioning/generator unit which will run in generating mode with simultaneous operation of the heat exchange element/ cooling fans assembly when a motive power is supplied by an auxiliary drive or use the motive power developed by generator operated in an electric motor mode to run all elements of the unit (compressor, cooling fans of condenser and evaporator, etc.) when an electric power is available. A constrained kinematic chain of the unit comprises, in combination, the following links: a stationary link having rigidly fixed to stationary frame a motor-stator and a stationary crankshaft; a rotating link comprising the compressor with secured to it the condenser/cooling fan assembly in the manner that rotation of the compressor triggers simultaneous unidirectional rotation of the condenser/cooling fan assembly, said rotating link spinning around the stationary crankshaft. Centrifugal force developed during spinning of the rotating link has been used for double-stage vapor-liquid (oil, liquid refrigerant) separation with simultaneous cooling of the separated fluids flow in the self-ventilating rotating link passages. Centrifugal force has been utilized also for delivery of oil to the parts required lubrication. Such oil delivery system does not required preliminary priming and eliminates traditional compressor oil pump. The oil sump of the compressor has been separated from such main “heaters” of circulating oil as discharge gas and windings of the motor-/generator which has been placed radially outside of the compressor. The following operations have been performed after compression of the aspirated gas: cleaning fluids from circulating solids and water by a plurality of filter-drier cartridges implanted in the compressor’s wall; forced delivery of fluids, to a discharge and lubricant supply channels formed in the stationary crankshaft ; forced delivery of a turbocharged suction vapor to the suction chamber. The compressor’s design excludes external accumulator and do not use roller and sliding vane, so, associated leakage and frictional losses do not exist. The vane of the compressor housing a plurality of integral (single piece) valves having semi-spherical head portion, a biasing section formed by conical spring with valve support, said valves which reduces re-expansion volume and increases the efficiency of the compressor.
