围护结构对微型冷库造价及性能有着重要的影响。通过有限生命周期内微型冷库经济性能的分析,推导了微型冷库在使用年限不同时的经济保温层厚度计算公式。并在此基础上分析了围护结构的变化对微型冷库降温性能的影响,结果表明降温性能与围护结构的参数具有紧密的联系,而与库体容积的关系最小。
Envelope structure has an important impact on the cost and performance of mini refrigerator. Through the analysis of the economic performance of miniature refrigerator in the limited life cycle, the formula of economic insulation thickness in the miniature refrigerator is deduced when service life is different. On the basis of the analysis, the influence of the envelope structure on the cooling performance of micro-refrigerator is analyzed. The results show that the cooling performance is closely related to the parameters of the envelope and has the least relation with the volume of the library.
