    • A beverage cooler (10, 100, 200) includes a heat pump (12) having a cooling element thermally coupled to a negative-heat-energy accumulator (14). The accumulator (14) includes a heat-energy dispersion arrangement (16) formed from thermally conductive material which is in thermal contact with a quantity of phase- change material (18) having a phase-change temperature above zero Celsius. A conduit (20) for the beverage defines a circuitous path thermally coupled to accumulator (14). The heat pump (12) draws heat energy predominantly from the phase-change material (18) so as to ensure that a temperature of the phase-change material is reduced by at least as much as the temperature of the beverage within conduit (20), even under zero-flow conditions. This ensures that the accumulator (14) can be fully charged during periods of low beverage dispensing demand without risk of freezing the beverage within conduit (20).
    • 饮料冷却器(10,100,200)包括具有与负热能蓄能器(14)热耦合的冷却元件的热泵(12)。 蓄能器(14)包括由导热材料形成的热能分散装置(16),该导热材料与一定量的相变温度高于零摄氏度的相变材料(18)热接触。 用于饮料的导管(20)限定热耦合到蓄电池(14)的迂回路径。 热泵(12)主要从相变材料(18)吸取热能,以确保相变材料的温度至少与管道(20)内的饮料的温度相同, ,甚至在零流量条件下。 这确保了在低饮料分配需求期间蓄能器(14)可以完全充电,而不会导致管道(20)内的饮料冻结。
