    • A refrigeration appliance having at least two refrigeration compartments, each compartment having its own access door, is provided wherein there is a first evaporator for the first compartment the first evaporator operating at a first pressure level and a second evaporator for the second compartment, the second evaporator operating at a pressure level higher than the first pressure level. There is a control device for directing refrigerant to a selected one of the evaporators from a condenser and for preventing a flow of refrigerant into the first evaporator when refrigerant is being directed into the second evaporator to cool the second compartment. Around the first compartment is placed insulation having a higher thermal resistance than that placed around the second compartment since the first compartment is kept at a lower temperature that the second compartment. A phase change material may be used in association with one or both of the evaporators.
    • 一种具有至少两个制冷室的制冷装置,每个隔室具有其自己的检修门,其中存在用于第一隔室的第一蒸发器,第一蒸发器在第一压力水平运行,第二蒸发器用于第二隔室,第二蒸发器 蒸发器在高于第一压力水平的压力水平运行。 存在用于将制冷剂从冷凝器引导到所选择的一个蒸发器的控制装置,并且当制冷剂被引导到第二蒸发器中以冷却第二隔室时,用于防止制冷剂流入第一蒸发器。 在第一隔间周围放置绝缘体,其具有比围绕第二隔室放置的热阻更高的热阻,因为第一隔室保持在较低温度下,第二隔间。 可以与一个或两个蒸发器相关联地使用相变材料。
