摘要
常用的冷库建筑结构型式有土建冷库、装配式冷库及混合式冷库三种,需要根据不同区域、地理环境、投资成本、运行成本等因素而决定采用何种型式。在选择冷库隔热材料时,应综合考虑导热系数、吸湿性、造价等因素。聚苯乙烯泡沫塑料、挤塑聚苯乙烯泡沫塑料和聚氨酯泡沫塑料是目前冷库广泛使用的保温隔热材料,介绍了各自的特点及国家和行业标准中对这些材料的性能要求。阐述了对保温材料厚度进行优化设计的原则。
Three kinds of construction tYpes for cold stores were introduced, i.e., civil structures, Prefab cold stores and hybrid cold stores. The selection principles inctuded the building regions, environmental conditions, the investment coats and the operating costs, The thermal conductivity,hyproscopicity and cost were the main factors that should be considered in choosing the thermal insulating materiala .The characteristics and standard performance requirements for three kinds of widely used thermal insulating materials were introduced,including the Styrofoam,Extruded polystyrene foam and Polyurethane foam.The designing methods to determine the optimized thickness of the thermal insulating materials were presented.
