本文针对目前山洞冷库建筑设计中的平面布置、巷道作法、洞体大小、防水处理和传冷计算等几个方面的问题,在对已建成的一些山洞冷库进行调查总结的基础上,结合冷库使用情况,进行热工性能分析、提出了进行设计的原则和方法。文中提出山洞冷库的平面布置、应尽量避免各个洞体细长而又分散的作法、最好呈“田”“目”字形;巷道温度应控制在0C以下、以兼作冷藏和通道两用的低温巷道最为经济合理。对于其围护结构的耗冷计算、作者认为取降温时间为一年、按不稳定传热计算公式,来计算山洞冷库和半地下的石拱复土冷库的耗冷量是较为经济合理的探讨意见。
In this paper, in view of the problems of the layout of the cave cold storage building, the roadway approach, the size of the cave body, the waterproofing treatment and the calculation of the cooling transmission, based on the investigation and summary of some established cave cold storage, Conditions, thermal performance analysis, put forward the design principles and methods. In this paper, the layout of the cave cold storage should be put forward. The slender and scattered methods of each cave should be avoided as far as possible. It is better to be in the shape of “Tian” and “Head”. The temperature of the roadway should be controlled below 0C to serve as both low temperature Roadway is the most economical and reasonable. For the calculation of the cooling consumption of the enclosure structure, the author thinks that taking the cooling time as one year, it is more economical and reasonable to calculate the cooling consumption of the cave-arch cold storage and semi-underground stone arch restoration by unsteady heat transfer formula opinion.
