介绍了一种节能、经济的改性夹套式蔬菜贮藏装置的概念和设计。大多数水果和蔬菜需要接近0°C和100%相对湿度的储存环境；这是传统制冷系统难以实现的。在带护套的存储系统中，冷冻空气在存储周围的空气空间中循环。高相对湿度水平可以通过使用墙壁、天花板和地板的大传热表面来实现，保持温度均匀，并防止热量进入存储空间。虽然护套概念最初是作为完整护套（覆盖墙壁、天花板和地板）引入的，但本文讨论了一种仅将天花板用作传热表面的替代护套设计。 基于结构的简单性，认为这种导管架设计可以应用于传统储存设施的转换和新的储存设施。可接受的相对湿度水平可通过带有延伸传热表面的夹套天花板设计实现。预计这一概念将在需要高湿度、中温冷藏室的水果和蔬菜储藏中得到良好的应用。引用:ASHRAE交易，第88卷，第2部分，加拿大多伦多

The development of an energy efficient and economical modified jacketed vegetable storageconcept and design is presented. Most fruits and vegetables require a storage environmentnear 0°C and 100% rh; which is difficult to achieve with conventional refrigeration systems.In a jacketed storage system, refrigerated air is circulated through air spaces surroundingthe storage. High relative humidity levels can be achieved through the use of the large heattransfer surface of walls, ceiling and floor maintained at uniform temperature, and bypreventing transmission heat gains into the storage space. While the jacket concept wasinitially introduced as a full jacket (covering walls, ceiling and floor), this paperdiscusses an alternative jacketed design which uses only the ceiling as a heat transfersurface. Based on construction simplicity, it is felt that this jacket design can be appliedto conversion of conventional storage facilities and to new storage facilities. Acceptablerelative humidity levels are attainable by the jacketed ceiling design with an extended heattransfer surface. It is expected that this concept will find favourable applications forstoring fruits and vegetables wherever high humidity, medium temperature cold rooms arerequired.
