本文根据对美国和加拿大公用冷库和对厦门主要冷库的调研,重点分析比较了冷藏库封闭式低温月台与常温月台,各种冷藏门的性能,以及与节能的关系。结果表明,低温冷库采用封闭式低温月台,不仅能最大限度地保证冻品的质量,而且具有明显的节能效果,应该大力推广。本文还介绍了国外冷藏门形式、启闭执行机构等技术方面的进展。 Based on the researches on the public cold storage in the United States and Canada and the main cold storage in Xiamen, this paper focuses on the analysis and comparison of the closed cold storage and the cold storage, the performance of various cold storage doors, and the relationship with energy saving. The results show that the use of closed low temperature cold storage platform, not only to ensure the quality of frozen products to the maximum extent, but also has significant energy savings, should be vigorously promoted. This article also introduced the foreign refrigeration door form, opening and closing implementing agencies and other technical advances.
