VEHICLE AIR CONDITIONER OPERATION METHOD Russian patent published in 2017 - IPC B60H1/00 

FIELD: transportation.

SUBSTANCE: to operate the vehicle air conditioner, mixtures of organic liquids are fed to the evaporation generator, to the liquid condensation chambers, to a heat exchanger connected to the chambers hydraulically with two flows, for cooling by endothermic cooling of organic liquids when mixed/sorbed. To cool the cabin/compartment of the vehicle and supply the generated cold to it, a salon radiator, a three-flow heat exchanger, pumps for the liquid supply are introduced. The mixture of organic liquids is divided into the components of the low-boiling and high-boiling liquid in the generator where evaporation is carried out while boiling by heating, using the breech energy from the exhaust system of the internal combustion engine or heat, from the cooling liquid circulating in the cooling system of the internal combustion engine, followed by condensation and cooling with external air of a low-boiling liquid in a low-boiling liquid chamber, and cooling of a high-boiling liquid in a high-boiling liquid chamber with external air. The temperature of both liquids is equalized before mixing during pre-cooling in the internal circuit of a triple-flow heat exchanger in which the liquids are cooled by heating a mixture of a low-boiling and high-boiling liquid flowing in counter-flow from the radiator of the passenger compartment. After pre-cooling in a triple-flow heat exchanger, the components are fed to a mixer where the low-boiling and high-boiling liquids are mixed, producing endothermic cooling of the mixture, which is fed to the compartment radiator to cool the air in the vehicle cabin/compartment. The mixture is supplied by an auxiliary pump to the outer loop of the three-flow heat exchanger to cool the components and feed them to the generator.

EFFECT: increased efficiency of the vehicle air conditioner.
