Description:FIELD OF INVENTION
[0001] Embodiments of a present disclosure relate to a field of heating ventilation and air conditioning systems and more particularly to an air intake device for automobiles and a method thereof.
BACKGROUND
[0002] In an automotive heating, ventilation and air-conditioning (HVAC) system air intake assembly is used to direct the fresh air from ambient and recirculation air from cabin into the HVAC module. The position of fresh air inlet and recirculating air inlet plays a critical role in the overall centrifugal blower performance used in automotive HVAC system and may be a key to deliver the required airflow with minimum noised level as felt inside the vehicle cabin. Besides the cross section of the fresh air and the recirculation air inlet, it positions dictates the air flow entering the blower mouth and there by the overall radial blower efficiency.
[0003] A conventional air intake system have a fresh air inlet that allows a system to bring fresh air in from outside and deliver it to inside an area where it is placed and a recirculation air inlet which cuts off the outside air to the inside of the area. The fresh air inlet and the recirculation air inlet are placed opposite to each other which may lower the blower efficiency and overall noise levels. Further, the conventional air intake system does not define the relative position of the fresh air inlet and the recirculation air inlet with respect to a blower inlet and outlet to deliver higher air flow performances. Furthermore, the conventional air intake system does not facilitate cabin comfort level as the unwanted air induces noise from the HVAC system.
[0004] Hence, there is a need for an air intake device for automobiles which addresses the aforementioned issues.

[0007] Yet, another objective of the present invention is to deliver higher air flow performances with reduced air induced noise.
