摘要
以某一低温实验装置为例,建立其围护结构非稳态传热数学模型,对动态负荷进行计算。研究表明,非稳态传热计算方法计算出的动态负荷符合围护结构非稳态传热的实际情况,可为制冷装置制冷量的确定、性能优化及节能提供理论依据。
A refrigerating plant was taken as an example. An unsteady thermal conduction model of its envelope was built and the dynamic load was calculated. The result indicated that the dynamic load obtained by the unsteady calculation method matches actual condition of unsteady thermal conduction, which can provide a theoretical base for determination on refrigeration capacity, performance opttmization and energy saving.
