HVAC UNIT FOR AIR TREATMENT IN VEHICLE PASSENGER CABIN, METHOD OF MEASURING CLIMATIC CHARACTERISTIC OF INTERNAL AIR IN VEHICLE PASSENGER CABIN AND HVAC UNIT IN VEHICLE PASSENGER CABIN Russian patent published in 2017 - IPC B60H1/00 B60H3/00 

FIELD: air treatment device.

SUBSTANCE: invention relates to devices for air treatment in a vehicle passenger cabin. HVAC housing has a recirculation intake section, a fresh air intake section, a supercharger section and a discharge section. Supercharger is installed in the supercharger section to move the air flow from the HVAC housing through the discharge section into the passenger cabin. Recirculation opening is provided near the recirculation intake section to deliver at least a primary flow of recirculation from the passenger cabin into the HVAC housing every time, when the supercharger moves the air flow. Climate sensor is connected by the fluid medium with the primary flow of recirculation to measure the climatic characteristic representing the air in the passenger cabin.

EFFECT: provided is better air mixing.
