DEVICE AND METHOD OF SELECTIVE MONITORING OF AIR INLET FOR AIR CONDITIONING SYSTEM Russian patent published in 2015 - IPC B60H1/02 B60S1/54 

FIELD: heating.

SUBSTANCE: invention relates to the of air flow regulation in cooling and heating system of the vehicle. The system and the method include the strategy of partial circulation control, when the air inlet shutter is smoothly moved to any position considering cooling/thermal load and possibility of the cabin sweating. Upon cooling/thermal load increasing the air intake shutter is moved to position of 100% circulation. If possibility of the cabin sweating occurs the air intake shutter is moved to position of 100% fresh air. The position selection between 100% circulation and 100% fresh air facilitates achievement of the optimal fuel saving and(or) power consumption of HV accumulator, without decreasing of the passenger comfort, and sweating of the internal surface of the glass. During cooling the compressor load is reduced, and air conditioning characteristics are improved due to decreasing of the evaporator cooling load.

EFFECT: reduced fuel consumption of the vehicle with internal combustion engine, reduced time of start-up of hybrid electric vehicle, and reduced energy consumption of HV accumulator in hybrid electric vehicle and common electric vehicle.
