    • A vapor compression thermal control system having at least one electrically powered evaporator fan and an apparatus for preventing compressor overloading apparatus having a sensor that measures temperature of air entering the evaporator. That measured temperature is compared with at least one predetermined temperature setting to activate a predetermined evaporator blower on/off duty cycle when the measured temperature exceeds the predetermined temperature. Alternatively, the apparatus can have a sensor that measures temperature of air being used to cool the condenser, and that measured temperature is then compared with at least one predetermined temperature setting to activate a predetermined evaporator blower on/off duty cycle when the measured temperature exceeds the predetermined temperature. In either case, it is evaporator air flow that is modulated when the system is operated as a heat pump. For liquid cooled evaporators, however the circulation pump instead of the fan is modulated.
    • 一种蒸汽压缩热控制系统,其具有至少一个电动蒸发器风扇和用于防止压缩机过载装置的装置,其具有测量进入蒸发器的空气的温度的传感器。 将该测量温度与至少一个预定温度设置进行比较,以在测量的温度超过预定温度时启动预定的蒸发器鼓风机开/关占空比。 或者,设备可以具有测量用于冷却冷凝器的空气的温度的传感器,然后将测量的温度与至少一个预定温度设置进行比较,以在测量温度超过时激活预定的蒸发器鼓风机开/关占空比 预定温度。 在任一情况下,当系统作为热泵操作时,其被调节的蒸发器气流。 对于液体冷却的蒸发器,然而调节循环泵而不是风扇。
