立式冷藏陈列柜内食品传热模型研究及温度预测
Temperature prediction and heat transfer model study of food product in vertical open refrigerated display cabinet
摘要
Abstract
Heat transfer by conduction,convection and radiation was taken into account in an open vertical display cabinet. The load positions were divided into four regions for a heat transfer model. The heat transfer model simplified as a two-dimensional problem was analyzed and modified. Then it was used to predict the load temperature in an open vertical display cabinet. The result showed that predicted values basically fitted with the experiment results. The deviation of bottom/front and top/rear load temperature between model and experiment was larger. The front load temperature changed more than the rear with the ambient temperature increase. And the result was coincided with the fact.关键词
