摘要
文章阐述了对于库温在零度以下的冷库,引起地坪冻胀的来源、防冻的重要性以及目前比较常用的地坪防冻处理方法。以广州某物流配送中心项目为例,通过简述冷冻油选择条件、地坪热量计算方法和系统设计原理,介绍了氟利昂冷库利用压缩机排气和电加热辅助热源加热冷冻油处理地坪冻胀的系统,这样不仅可以解决地坪冻胀问题,确保冷库长期使用,而且有效的减少冷凝热的排放,提高系统的制冷效率,最后指出了该系统施工中重点的注意事项。
the paper expatiate on the source of the ground from frost heaving, the importance of antifreeze and some antifreeze measures for cold store. By summarizing the selection of refrigeration oil, calculation Method for ground heating and the design principle of system. The system of using discharge with electrical heating is introduced in this paper. Not only ground from frost heaving can be resolved but also refrigeration efficiency can be increased by using this system, importance notice of construction is suggested in the last of the paper.
