摘要
为延长蔬果库内蔬果的保鲜周期,蔬果库内温度需要维持在较小波动范围.同时,为了进一步提升船舶冷库内库容利用率,蔬果库内采用密集贮存方式.在密集存储状态下,将蔬果库内温度波动范围控制在±0.5℃,开展蔬果库内密集贮存下蔬果库送风方式的仿真研究.通过建立蔬果库内气流组织仿真模型,对密集贮存条件下冷风机直接送风和顶部采用可调风口送风2种不同送风方式进行仿真研究.结果表明:采用顶部可调风口送风可保证密集贮存条件下库内大部分区域温度场波动不超过±0.5℃,满足精确控温需求.研究成果可为后续实船的冷库布置及送风方式选择提供一定参考.
Abstract
To extend the preservation period of fruits and vegetables within the storage facility,maintaining the temperature within a minimal fluctuation range is essential.Additionally,to further enhance the storage capacity utilization in ship cold storage units,a dense storage approach is adopted within the fruit and vegetable storage.To achieve a temperature fluctuation range of±0.5 ℃ under dense storage conditions,a simulation research is conducted on the airflow supply methods for the fruit and vegetable storage in a densely packed setting in this study.By establishing a simulation model for airflow organization within the storage,two distinct air supply methods were evaluated:direct air supply from the cooling fan and an approach utilizing adjustable vents are located at the top.The findings indicate that employing adjustable vents at the top ensures that the temperature fluctuation within most areas of the densely stored storage does not exceed±0.5 ℃,meeting the requirements for precise temperature control.Valuable insights are provided by these research outcomes for the subsequent layout and air supply method selection for cold storage units on actual ships.
