摘要
本文依据传热的基本原理 ,针对具有空气冷却和加热功能的环境试验箱围护结构隔热层的传热特性参数———传热系数和蓄热系数 ,用非稳态测量方法进行了比较试验。提出一种较为实用的测量方法 :它是利用隔热箱内升。
Based on the principle of heat transfer, the unsteady theory (temperature up and down) analysis the heat transfer coefficient and the retaining heat parameter for an cooling and heating test chamber's isolated heat structure is established. Using mathematical treatment, the heat transfer equations are simplified to be suited for the practical measurement, and the experimental verification is made on good result. In this paper the theory and method of measuring heat transfer coefficient and retaining heat parameter is presented and compared.
