Abstract: A heating, ventilation, and air condition (HVAC) system of a work vehicle includes a housing configured to mount to a structure of a cab of the work vehicle. The housing includes at least one mounting assembly configured to support at least one heat exchanger within the housing, and the at least one mounting assembly is configured to position the at least one heat exchanger such that the at least one heat exchanger extends through the structure from an interior of the cab to an exterior of the cab while the at least one heat exchanger is coupled to the at least one mounting assembly.

Abstract: A system for controlling an airflow supplied to a cabin of a work vehicle may include a housing defining a mixing chamber and a recirculating chamber isolated from the mixing chamber. The mixing chamber is configured to receive fresh air via a fresh air inlet and recirculated air via a first recirculated air inlet, with the fresh air being mixed with the recirculated air within the mixing chamber to create a fresh/recirculated air mixture that is supplied through a mixed air outlet. The recirculating chamber is configured to receive recirculated air via a second recirculated air inlet and supply the recirculated air through a recirculated air outlet. Additionally, the system may include a gate movable relative to the first recirculated air inlet to adjust an amount of recirculated air supplied to the mixing chamber, and an actuator configured to actuate the gate relative to the first recirculated air inlet.

Abstract: A cab for a work vehicle includes: walls enclosing a cab environment; a door coupled to one of the walls, one of the walls or the door comprising a vent opening; a heating, ventilation, and air conditioning (HVAC) system coupled to the cab environment and configured to regulate a temperature and a pressure of the cab environment; and a pressure control flap associated with the vent opening and comprising a pressure-relief opening and a magnetic portion that is configured to hold the flap closed when the pressure of the cab environment is below a threshold pressure and allow the pressure to open the flap when the pressure exceeds the threshold pressure.

Abstract: A vehicle including a cab having a frame with at least two support posts each including an airflow path therein and an airflow system supported by the cab and configured for increasing an airflow into the cab and decreasing a power consumption of the cab. The airflow system includes at least one air intake opening in the cab configured for intaking a fresh air, an air filter fluidly coupled to the at least one air intake opening, and an air outlet within the cab and fluidly coupled with the air filter. The fresh air flows into the at least one air intake opening, through each respective airflow path of the at least two support posts, is filtered by the air filter, and flows out through the air outlet into the cab.

Abstract: An air intake system for a work vehicle is disclosed. The air intake system may generally include a filter assembly having a pre-cleaner configured to separate particulates from air received within the filter assembly. The pre-cleaner may define a pre-cleaner outlet. In addition, the air intake system may include a blower having a fan and a housing encasing the fan. The fan may be configured to create a vacuum such that the particulates separate from the air are expelled from the pre-cleaner outlet and flow into the housing. The housing may define a blower outlet through which the particulates are expelled from the housing. Moreover, the flow of particulates through the blower outlet may be oriented non-parallel to a rotational axis of the fan.

Abstract: An HVAC system for a work vehicle having an operator compartment for a vehicle operator, the system including a heating system, a compartment pressurizer blower, a compartment recirculation blower, a temperature sensor, and an operating mode switch, each operably coupled to an electronic circuit, wherein the circuit is configured to reduce pressurizer blower output when the operator selects high output from the heating system under certain predetermined temperature and conditions and operating modes to improve HVAC system performance.

Abstract: A work vehicle comprises an internal combustion engine and a catalytic converter coupled to the exhaust of the engine. A reduction agent system provides for injection of a reduction agent, such as urea, upstream of the catalytic converter. Coolant heated by the engine is directed to the reduction agent system to defrost/heat the reduction agent, and is also directed to a vehicle cabin heating system. Flow of coolant may be preferentially directed to the cabin heating system rather than to the reduction agent system, such as following vehicle startup, particularly during cold-weather operation. Flow may be altered to favor the reduction agent system, such as based upon time and/or the temperature of the cabin.

Abstract: An HVAC system for work vehicle having an operator compartment for an operator is disclosed. The HVAC system includes a pressurizer blower and an air-conditioning system coupled to an electronic circuit. The electronic circuit is configured to reduce the output of the pressurizer blower when the operator selects a high output from the air-conditioning system. The HVAC system is also configured to provide defog operation in both a manual mode and an automatic mode of operation. The HVAC system is configured to reset the defog operation when the vehicle ignition is turned off or turned back on. The HVAC system is also configured not to reset the defog operation when the operator switches rapidly between the automatic mode and the manual mode of operation.
