SYSTEM AND METHOD FOR REGULATING ENVIRONMENT WITHIN OPERATOR CABIN OF MACHINE

-26 Abstract SYSTEM AND METHOD FOR REGULATING ENVIRONMENT WITHIN OPERATOR CABIN OF MACHINE A system (200) for regulating an environment within an operator cabin (112) of a machine (100) via a heating, ventilation, and air conditioning (HVAC) system (200) includes a first sensor (204) that generates a first signal (Sl) of an amount of air pressure within the operator cabin (112), a second sensor (206) that generates a second signal (S2) of an amount of carbon dioxide within the operator cabin (112), an air filtration element (208) to direct pre-cleaned air into the operator cabin (112), an inlet valve (210) disposed between the air filtration element (208) and the HVAC system (126) for controlling a flowrate of the pre-cleaned air to the HVAC system (126), and a controller (212). The controller (212) actuates dynamic auto-control of the inlet valve (210) to direct an optimally varying flowrate of the pre-cleaned air from the air filtration element (208) to the HVAC system (126) via the inlet valve (210) to maximize a service life of the air filtration element (208).
