| 目的 研究蓄冷剂质量对挤塑聚苯乙烯保温箱温控效果的影响。方法 在3种不同的外界温湿度环境条件下， 向保温箱内部加入不同质量的蓄冷剂， 研究蓄冷剂质量对挤塑聚苯乙烯保温箱温控效果的影响。结果 加入不同蓄冷剂质量时， 保温箱内各点的保温时间不同， 但均遵循着一个规律， 即保温箱底层测点的保温时间>中层测点的保温时间>上层测点的保温时间。在温度为23 ℃和相对湿度为50%的外界环境下， 30 mm厚的XPS保温箱内蓄冷剂与药品质量比为4∶1时， 能够有效保存药品在2~8 ℃， 保温时间达到24 h以上。建立了挤塑聚苯乙烯保温箱中心点处的外界温度-蓄冷剂与药品质量比-保温时间的三维模型。结论 蓄冷剂结合聚苯乙烯保温箱内部温度可控制在2~8 ℃， 满足冷藏药品短途快递运输的温控要求。 |
| 英文摘要: |
| This work aimed to study the effect of the coolant amount on the temperature control of extruded polystyrene insulation box. Different amount of coolant was added into the box at three different external temperature and humidity conditions. Influences of the coolant amount on temperature control effect of extruded polystyrene insulation box were studied. When different amount of coolant was added, the temperature holding time at different sites in the insulation box was different, but a common law was obeyed. The temperature distributing law inside the extruded polystyrene insulation box was that the holding time of the bottom test point was longer than the middle than the top. When the mass ratio of coolant and refrigerated drugs was 4∶1, the holding time of the box could reach 24 hours at 23 ℃ and 50% RH. And the 3D model of central point about the external temperature and mass ratio of coolant and refrigerated drugs and holding time was built. The temperature inside the insulation box could be controlled at 2-8 ℃ by combining the extruded polystyrene box and coolant, which could meet the requirement of temperature control for short-distance transportation of refrigerated drugs. |
