Title:
HVAC SYSTEM FOR A WORK VEHICLE
Document Type and Number:
WIPO Patent Application WO/2012/107512
Kind Code:
A1
Abstract:
An HVAC system (48) for a work vehicle (10) having an operator cab (20) includes a first chamber (50) having an inlet (54) for receiving airflow (56) exterior of the cab. The inlet is adjacent to a first source for moving air (40) for use independent of the HVAC system, the inlet arranged to cause a first change of direction (60) of airflow inside the first chamber. The first chamber resulting in both a first air pressure reduction (64) and a first reduction of airflow velocity (66) while inside the first chamber sufficient to reduce an amount of particles (68) entrained in the airflow while the particles are within the first chamber. A second chamber (78) in fluid communication with the first chamber and configured to cause both a second change of direction (80) and a third change of direction (82) of airflow while inside of the second chamber prior to reaching a third chamber (88) for mixing air flow with re-circulated air from the cab.
