Abstract:
1. An HVAC system for a work vehicle having an operator compartment for an operator, the system comprising: means for cooling air in the operator compartment having an evaporator, and a manually operable temperature control means; a means for recirculating air; means for pressurizing air in the operator compartment; and means coupled to both the means for cooling air and the means for pressurizing air for reducing output from the means for pressurizing air when the operator selects high output from the means for cooling air; the temperature control means allowing direct operator adjustment of the temperature of the evaporator, such that the temperature of the evaporator is proportional to an operator selected setting of the temperature control means; wherein high output is achieved in a manual mode by selecting operation of the cooling means at the lower of at least two selectable evaporator temperatures settings and the means for recirculating air operating at the higher of at least two operating settings.
