摘　　要：为解决船舶果蔬库存在的库内温度波动范围大、气流组织欠佳和气调库应用受限的问题,满足船舶航行期间的果蔬供应需求,对精确控温冷藏保鲜系统进行研究。该系统通过优化制冷负荷调控技术,避免机组频繁启停造成库内温度发生波动;采用孔板稳压送风方式,使库内气流充分混合,形成均匀的气流组织;制订综合布置方案和安装工艺,保证孔板送风的功能性和可靠性满足要求。此外,该系统运用分区控温技术,根据果蔬种类的不同设置适宜的贮藏温度,防止“冷害”发生,并辅以加湿设施和气调包装保鲜技术,进一步提升果蔬的保鲜效果。经实船验证,该精确控温冷藏保鲜系统能使果蔬保鲜期延长到45 d,孔板送风方式具有较好的应用效果。In order to solve the problems of large temperature fluctuation,poor airflow circulation,and limited use of air-controlled hold in storing fruit and vegetable onboard ship,a precisely temperature-controlled refrigerating and preserving system has been designed to meet the demand for fruit and vegetable supply in the long voyage.This system optimizes the refrigeration load regulating technology to avoid the temperature fluctuation caused by frequent startup and shutdown.Orifice plates are used to stabilize the pressure of air supply so as to make the air flow in the hold fully mixed to form a uniform air flow organization.Meanwhile the comprehensive layout plan and installation process are formulated to ensure the functionality and reliability of orifice plate air supply.In addition,the system uses zonal temperature control technology to set appropriate storage temperatures for different fruits and vegetables to prevent“cold damage”and is supplemented by humidification facilities and air-controlled packaging technology to further improve the preservation effect of fruits and vegetables.Onboard verification shows that the precisely temperature-controlled refrigerating and preserving system can extend the preservation period of fruits and vegetables to 45 days,and that the orifice plate air supply method has good application effect.
