中文摘要:为解决冷藏运输车厢内温度场分布不均匀直接导致杨梅等特色水果营养成分和品质变差等问题,通过正交试验法优化设计,引入温度场均匀性评价指标,分析了气流循环风机转速、匀流板孔隙率和货框垂直间距等因素对冷藏运输车厢内温度场的影响。结果表明:风机转速越高,温度场均匀性越好,厢内的最高温度基本不变;孔隙率越小,温度场均匀性越好,孔隙率0.1时厢内最高温度最低;在一定范围内垂直间距越小,最高温度越低,均匀性也越好。针对温度场中存在的“高峰”区域,基于场协同原理设计了冷藏运输厢体结构,通过调节右侧回风口处气帘风机的方向实现了均匀性控制。

Abstract:Evaluating indicator for temperature distributions homogeneity was developed through optimization using orthogonal experiment. The influences of rotation speed of air refrigerating machine fan, porosity of flow equalization board and vertical space between frames on temperature distribution were analyzed. The simulation results show that the higher the fan rotation speed is, the better the temperature distribution homogeneity is, although the highest temperature in carriage is basically unchanged; the smaller the porosity is, the better temperature distribution homogeneity is; and the highest temperature in carriage is lowest when the porosity is 0.1; the smaller the frame vertical spacing is, the lower the highest temperature in carriage is and the better temperature distributions homogeneity is. For the “peak area” in temperature distribution, the carriage structure was new designed based on field-coordination principle and the temperature distributions homogeneity can be controlled by adjusting the gas curtain fan’s direction in right air-returning outlet.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
