从我国地下冷库廿年的发展史来看,不少问题急待研究和解决,例如:建筑耗冷量大(约为地面冷库的二倍)、岩层破裂、库内浸漏水以及干耗大等。本文通过调研、热工实测,在总结现有冷库的基础上指出:地下冷库必须进行周密的建筑和热工设计,特别是南方地区,还应有恰当的热绝缘措施,否则它将有天折的危险。事实上目前我国地下冷库的5～10%已经或即将报废。本文从冷库建筑节能的观点出发,考虑其经济效益和社会效益,强调了地下冷库选址、建筑和热工设计的重要性、并对南方地下冷库热绝缘的设计原则,计算方法以及绝缘构造等作了较详细的论述。作者根据以上设计原则、经过长期的工程实践,并列举了三座建筑设计合理、建筑形式优良、热绝缘构造新异、使用效果好的典型实例,充分证明了地下冷库当前存在的问题不但可以克服,而且还可提高冷藏质量和冷库的科学水平。
From the history of the development of China’s underground cold storage year, many problems are urgently needed to be studied and solved. For example, the building consumes large amounts of cold (about twice the amount of cold storage on the ground), the rock bursts, the leakage of water in the reservoir, and the large amount of energy consumed. . Based on summarizing the current cold storage, the paper points out that the underground cold storage must be well-constructed and designed for thermal engineering. In particular, in the south, there should be appropriate thermal insulation measures. Otherwise, it will have days off. danger. In fact, at present, 5 to 10% of China’s underground cold storage has been or will soon be scrapped. This article from the perspective of energy-saving cold storage building, considering its economic and social benefits, emphasizing the importance of the underground cold storage site, construction and thermal design, and the design principles, calculation methods and insulation structure of the underground thermal insulation in the South Made a more detailed discussion. Based on the above design principles and after long-term engineering practice, the author listed typical examples of three buildings with reasonable design, excellent architectural forms, different thermal insulation structures, and good use effects, which fully proved that the current problems in the underground cold storage can not only overcome , but also improve the quality of refrigeration and the scientific level of cold storage.
