    摘要: A cooling system (60) for cooling one or more heat-generating devices (62), wherein the system (60) includes a heat sink to which the one or more heat-generating devices (62) are thermally coupled and a heat exchanger (100) thermally coupled to the heat sink. The heat exchanger (100) has a first flow path for receiving a primary cooling fluid (C1) and a second flow path for receiving a secondary cooling fluid (C2). Heat is transferable to the primary cooling fluid (C1) from both the heat sink and the secondary cooling fluid (C2) at the heat exchanger (100).

    摘要: An energy-efficient heat pump water heating system determines whether to energize a heat pump by interpreting readings from one or temperature sensors based on two thresholds. The heat pump is energized if the detected temperature falls below a first threshold and de-energized when the detected temperature rises above a second threshold. The thresholds may correspond to outputs of two or more sensors. Using multiple temperature thresholds improves the temperature sensing capabilities of the system, thereby improving energy efficiency by matching heat pump operation with hot water demand more closely than previously known systems.

    摘要翻译: 高能效热泵热水系统通过基于两个阈值解读来自一个或多个温度传感器的读数来确定是否激活热泵。 如果检测到的温度下降到第一阈值以下,则热泵被通电,并且当检测到的温度上升到第二阈值以上时被断电。 阈值可以对应于两个或更多个传感器的输出。 使用多个温度阈值提高了系统的温度感测能力,从而通过比先前已知的系统更加紧密地匹配热泵操作与热水需求来提高能量效率。
