【摘要】 为解决保鲜运输用高压雾化加湿系统设计问题,建立了高压雾化加湿系统的试验平台。通过改变风速、开孔率、回风道长度等因素,研究各因素对加湿系统加湿效率和湿度分布的影响,分析高压雾化加湿系统的湿度调节特性。结果表明:压力室和开孔隔板的设计合理可行;高压雾化加湿系统加湿效率与风速、开孔率呈非线性关系;在风速和开孔率相同的情况下,回风道长度越大贮藏环境湿度分布越均匀;并进一步分析了保鲜室内湿度分布情况。研究结果对保鲜运输用高压雾化加湿系统的设计具有一定的参考价值。更多还原

【Abstract】 A specil high pressure atomized humidifying test-bed was established to research the design of humidifying system for the fresh-keeping transportation. The regulation characteristics of specil pressure atomized were studied. The effects of airflow velocity, ratio of open area and length of the return air path on the characteristics of humidify efficiency and humidity distribution were analyzed. Some relationships were found out. According the calculation formula of corrugated carton compression strength, the reliability of the design of pressure room and perforated baffle was demonstrated. The relation between humidify efficiency and airflow velocity, ratio of open area and length of the return air path humidity was nonlinear. At the same airflow velocity and ratio of open area, the longer the return air path, the minor humidity uniformity was. The research achievements were instructive to the optimization design of the humidify system for fresh-keeping transportation.更多还原
