    • A HVAC system 75 for a vehicle 10 that includes a propulsion system, a frame 15 and a door 35 coupled to the frame. The HVAC system includes a refrigeration circuit that selectively controls the temperature of the vehicle based on a sensed temperature within the vehicle. The refrigeration circuit includes an exterior heat exchanger, a first air moving device coupled to the exterior heat exchanger, an interior heat exchanger, a second air moving device coupled to the interior heat exchanger, and a compressor. The HVAC system also includes a controller that is operable to detect a condition of the vehicle that includes at least one of a location of the vehicle, and a load of the propulsion system. The controller is programmed to adjust the refrigeration circuit in response to the sensed temperature of the vehicle and the detected vehicle condition. The controller is programmed to decrease a speed of at least one of the first air moving device, the second air moving device, and the compressor in response to detection of a first condition of the vehicle and to increase the speed of at least one of the first air moving device, the second air moving device, and the compressor that was previously operated at a decreased speed in response to detection of a second condition of the vehicle. The first vehicle condition includes the location of the vehicle detected in close proximity with a freestanding structure, and the second vehicle condition includes the location of the vehicle detected at least a predetermined distance from the freestanding structure.
    • 用于车辆10的HVAC系统75,其包括推进系统,框架15和联接到框架的门35。 HVAC系统包括一个制冷回路,该制冷回路基于车辆内感测到的温度选择性地控制车辆的温度。 制冷回路包括外部热交换器,联接到外部热交换器的第一空气移动装置,内部热交换器,联接到内部热交换器的第二空气移动装置和压缩机。 HVAC系统还包括控制器,其可操作以检测包括车辆位置和推进系统的负载中的至少一个的车辆状态。 控制器被编程为响应于感测到的车辆温度和检测到的车辆状况来调节制冷回路。 控制器被编程为响应于车辆的第一状况的检测而降低第一空气移动装置,第二空气移动装置和压缩机中的至少一个的速度,并且增加至少一个 第一空气移动装置,第二空气移动装置和压缩机,其响应于车辆的第二状态的检测而以较低的速度运行。 第一车辆状态包括在非常靠近独立结构的情况下检测到的车辆的位置,并且第二车辆状态包括从独立结构至少预定距离上检测到的车辆的位置。
