Abstract: Systems are disclosed for providing a work vehicle with a second air conditioning compressor driven by a small engine mounted on the work vehicle. The second compressor shares a refrigeration loop with the primary air conditioning compressor of the work vehicle. The small engine may be configured to drive various loads, and accordingly may include control circuitry to manage the power provided to the various loads, including the second compressor.

Abstract: A vehicle includes an electric machine, a coolant circuit, a refrigerant circuit, and a controller. The electric machine is configured to charge a battery via regenerative braking. The coolant circuit has an electric heater. The refrigerant circuit has an electric compressor. The controller is programmed to, responsive to a capacity of the battery to receive power being less available regenerative braking power and ambient air temperature being less than a first threshold, direct regenerative braking power to the heater but not the compressor. The controller is further programmed to, responsive to the capacity of the battery to receive power being less available regenerative braking power and ambient air temperature exceeding a second threshold that is greater than the first threshold, direct regenerative braking power to the compressor but not the heater.

Abstract: A method of controlling an air conditioner includes determining whether or not a signal for operating the air conditioner is input to a controller. When it is determined that the signal for operating the air conditioner is input to the controller, determining whether or not conditions for variably controlling the air conditioner are satisfied. When it is determined that the conditions are satisfied, an energy flow mode is checked on the basis of an energy flow between a battery, a motor, an engine, and electric components. The air conditioner is controlled in a mode corresponding to the checked energy flow mode.
Abstract translation: 控制空调的方法包括确定用于操作空调的信号是否被输入到控制器。 当确定用于操作空调的信号被输入到控制器时，确定是否满足可变地控制空调的条件。 当确定满足条件时，基于电池，电动机，发动机和电气部件之间的能量流量来检查能量流动模式。 空调器以对应于所检查的能量流模式的模式被控制。
