VEHICLE AIR CONDITIONER Russian patent published in 2014 - IPC B60H1/32 F25B5/00 

FIELD: transport.

SUBSTANCE: invention relates to machine building, particularly, to air conditioning units to control microclimate in vehicle cabins. Air conditioner comprises condenser, mixer, heat exchanger, pump, receiver, generator 1 and refluxer. Cooling circuits incorporate radiators built around low- and high-boiling fluid tubes. High-boiling fluid circuit comprises S-like pipeline 10 heated at bottom section communicating bottom part of fluid separator 2 with top section of two-flow heat exchanger 12 communicated with sop section of fluid separator 2 of breather tube 11. Reversible pump 20 to cycle the mix through two-flow heat exchanger back into generator 1 is arranged downstream of three-flow heat exchanger at fluid mix flow pipeline 19. Cabin radiator is communicated with extra bypass pipeline 24 furnished with check valve 23 to open in heating mode and to close in cooling mode.

EFFECT: higher efficiency of air conditioner, optimised climate in vehicle cabin, use of vehicle waste heat, for example, that of ICE exhaust gas or heat of electric vehicle storage batteries.
