摘要
根据隔热材料的热物理性质、现行价格和冷库构造及使用要求 ,采用模糊综合评判法选择隔热材料。采用经济厚度法确定隔热层厚度 ,此方法着眼于经济效果 ,使隔热层的初投资、经营管理费用和食品干耗损失费用之和趋于最小。用矩阵实验室 5 .3(MATLAB 5 .3)对冷库隔热层进行优化设计计算 ,力图获得安全、经济的效果。
Considering the thermophysical properties and price of insulating material, the structure and requirements of a cold storage, the type of insulating material was selected by the method of fuzzy multiple judgement, the thickness of the insulating layer was decided by the method of economical thickness which was based on economic benefit. Therefore the sum of the initial investment, the operating cost and the drying loss cost was reduced to a minimum. MATLAB 5.3 was used to optimize the design of insulating material. The economical and reasonable results were obtained.
