    • An improvement in refrigeration assemblies for use in conjunction with cooler structures in which food products are preserved in which an assembly of unitary, modular construction is utilized to selectively provide the refrigeration of the air mass. The assembly can be air defrosted by arranging for the flow through of ambient air to defrost the evaporator coils. At the same time, the flow of ambient air can be blocked against entry into the refrigerated air mass by the use of movable baffles. Cover gates are arranged on the assembly to permit the through flow of ambient air during the defrost cycle of operation.The refrigeration assemblies can be employed for retrofitting and on an interchangeable basis for structures to be refrigerated.
    • 与用于保存食品的冷却器结构一起使用的制冷组件的改进,其中使用一体式模块化结构的组件来选择性地提供空气质量的制冷。 组件可以通过布置通过环境空气的流动来除霜蒸发器盘管来进行空气除霜。 同时,可以通过使用可移动挡板来阻止环境空气的流动进入冷藏空气块。 封盖门布置在组件上,以允许在除霜操作的循环期间通过环境空气的流动。 制冷组件可用于改装,并可在可冷却的结构的可互换基础上使用。
