【摘要】：本文通过数值模拟的方法,将自然冷源引入卧式陈列柜,研究其柜内食品温度在不同工况下的变化规律。结果表明:柜内食品包的温度随着室外冷源温度的升高而升高,当室外温度处于-2~5℃范围内时,柜内贮藏温度能够维持在0~7℃之间,其他室外冷源温度时,需与陈列柜制冷系统联合循环。在实际运行中,在室外环境温湿度为-1℃、22%RH,室内环境温湿度为22℃、55%RH的条件下,柜内食品的贮藏温度最佳。
[Abstract]:In this paper, the natural cold source is introduced into horizontal display cabinets by numerical simulation, and the variation of food temperature in the cabinets under different working conditions is studied. The results showed that the temperature of food package increased with the increase of outdoor cold source temperature. When the outdoor temperature was in the range of -2 ~ 5 鈩，
