    • An improved vehicle heating and air conditioning system (10) includes a driver-manipulated temperature selector (94) that is physically coupled to a discharge temperature control mechanism (56). The selector (94) is operable in a normal mode in which movement of the selector (94) away from a full cold setting produces a corresponding movement of the temperature control mechanism (56) that increases the discharge air temperature by re-heating or a high fuel efficiency mode in which movement of the temperature selector (94) away from the full cold setting allows the temperature control mechanism (56) to remain in a full cold position for a limited range of selector movement while the discharge air temperature is increased by capacity reduction of the refrigerant compressor (12). The temperature selector (94) is in the form of a rotary knob (122) that is axially shiftable to change modes when the selector (94) is positioned at the full cold setting and spring-biased so that the normal mode is established as the default mode.

    • In an air conditioning system (10) for controlling the temperature of a vehicle passenger compartment, a valve (107) is disposed in a fluid passageway for controlling an amount of the engine coolant flowing toward the heat exchanger (103). A sensor device (16) senses an air temperature for the air flow through the heat exchanger and generates an electrical sensor signal indicative thereof. A temperature selector selects a target temperature of the air flow through the heat exchanger (103) and generates an electrical set signal indicative thereof. A control circuit (18) controls opening of the valve (107) by integrating a feed-back control and a feed-forward control based on the electrical sensor signal and the electrical set signal. Therefore, the air conditioning system (10) is adapted for improving control response characteristics without influences from disturbances and ensures improved control to provide stable control with rapid response to achieve a target temperature or a modification to the set temperature inside of the automobile compartment, or both.
    • 在用于控制车辆乘客室温度的空调系统(10)中,阀(107)设置在流体通道中,用于控制流向热交换器(103)的发动机冷却剂的量。 传感器装置(16)感测通过热交换器的气流的空气温度,并产生指示其的电传感器信号。 温度选择器选择通过热交换器(103)的气流的目标温度并产生指示其的电气设定信号。 控制电路(18)通过基于电传感器信号和电设置信号对反馈控制和前馈控制进行积分来控制阀(107)的打开。 因此,空气调节系统(10)适用于改善控制响应特性而不受干扰的影响,并且确保改进的控制以提供稳定的控制以快速响应以达到目标温度或对汽车车厢内的设定温度的修改,或者 都。
