    • A low-temperature showcase in which a double air curtain can be formed for commodity inlet-outlet opening provided in one side of its main body comprising: a heat exchanger in an inner passage being positioned upstream of and at a predetermined distance from another heat exchanger in an outer passage with respect to the same direction of air flows, a partition wall defining the inner and outer passages and having a first window at a portion thereof between the two heat exchangers, a closure plate for opening or closing the first window to close or open the inner passage downstream of the first window, and first control unit for giving instructions to the closure plate for its operation, the first control unit being operative to instruct the closure plate to open the first window and close the inner passage downstream of the first window when the heat exchanger in the inner passage is operated for defrosting with the heat exchanger in the outer passage operated for refrigeration, whereby the air flow through the heat exchanger in the inner passage is guided into the outer passage through the opened first window and cooled by being passed through the heat exchanger in the outer passage.
    • 一种低温陈列柜,其中可以形成用于在其主体的一侧设置的商品入口 - 出口的双气帘,包括:内通道中的热交换器,位于与另一热交换器 在相对于相同空气流动方向的外部通道中,限定内部通道和外部通道并且在其两个热交换器之间的部分具有第一窗口的分隔壁,用于打开或关闭第一窗口以闭合的封闭板 或打开第一窗口下游的内部​​通道,以及第一控制单元,用于向封闭板指示其操作,第一控制单元可操作以指示封闭板打开第一窗口并将第一窗口的下游的内部​​通道关闭 第一窗口,当内部通道中的热交换器被操作以用于用于制冷的外部通道中的热交换器进行除霜时,其中b 通过内部通道中的热交换器的空气流被引导到通过打开的第一窗口的外部通道中,并且通过穿过外部通道中的热交换器而被冷却。
