【摘要】：为探究保温盖启闭状态对冷藏柜温度场分布的影响,本文以海绵和500 g水组成的塑料包模拟冷藏食品并置于冷藏展示柜内。采用T型热电偶测量冷藏展示柜内的温度分布,并用ORIGIN软件得到冷藏柜各层测点温度分布和各层的温差。基于此分析了保温盖启闭状态对冷藏柜内温度场分布规律的影响。结果表明:当冷藏保温盖开启时冷藏柜内部顶层食品包温度受影响最大,各层之间的温度梯度变大,温度集中在0℃左右。保温盖闭合时冷藏柜内温度集中在-1.5℃左右。
[Abstract]:In order to investigate the influence of the opening and closing state of the heat preservation cover on the temperature field distribution of the freezer, a plastic package composed of sponge and 500 g water was used to simulate the refrigerated food and put it in the refrigerated display cabinet. The temperature distribution in the refrigerated display cabinet was measured by T-type thermocouple, and the temperature distribution and temperature difference of each layer of the freezer were obtained by ORIGIN software. Based on this, the influence of the opening and closing state of the heat preservation cover on the temperature field distribution in the freezer is analyzed. The results show that when the refrigerated heat preservation cover is opened, the temperature of the top layer of the freezer is the most affected, the temperature gradient between the layers becomes larger, and the temperature is concentrated at about 0 鈩，
