    • The present invention provides a refrigeration display cabinet, a refrigeration system and a constant temperature control method. The refrigeration display cabinet includes: a refrigeration loop (110), including a compressor (111), a condenser (112), a throttling element (113) and an evaporator (114) which are connected in sequence through pipelines; and a control device (120) communicated with the refrigeration loop and used for directly or indirectly controlling the saturated suction temperature of the refrigeration loop in a preset threshold value range of -2 DEG C to +2 DEG C, wherein the evaporator is a finned heat exchanger, and has a fin density of not less than 6FPI. The refrigeration loop can provide high enough refrigeration capacity for the refrigeration display cabinet and avoid a frosting problem of the fins of the evaporator, thus avoiding a frosting blockage problem of the fins.
    • 本发明提供了一种制冷展示柜,一种制冷系统和一种恒温控制方法。 所述制冷展示柜包括:制冷回路(110),所述制冷回路(110)包括依次通过管道连接的压缩机(111),冷凝器(112),节流元件(113)和蒸发器(114) 和控制装置(120),与制冷回路连通,用于直接或间接控制制冷回路的饱和吸入温度在预设的阈值范围-2℃至+ 2℃范围内,其中蒸发器为翅片 换热器,翅片密度不小于6FPI。 制冷回路可为制冷展示柜提供足够高的制冷能力,避免了蒸发器翅片的结霜问题,避免了翅片的结霜堵塞问题。
