摘要： 预冷对果蔬采后品质调控和货架期延长具有重要意义。目前的预冷方法有空气冷却法、强制空气冷却法、水冷法、真空冷却法、接触式或包裹式结冰法、低温冷却法等，以上方法各有优缺点。前两种是以空气为冷却介质的方法，因其适用范围广而被广泛应用。针对这两种空气预冷方法的缺点，通过各种评价标准和优化方法进行了大量的研究。本文首先对这两种方法的实验和数值研究进行了系统的文献综述。本文还总结了前人的主要研究成果，包括研究目标和性能标准。文献表明，目前的性能评价仅限于表观参数，仅在性能评价和比较的基础上提出优化设计。此外，借鉴其他领域的研究成果，从多学科的角度，结合热力学评价指标和结构优化方法，提出了一种先进的空气预冷方法评价与优化方案。

Abstract: Precooling is of significant importance for postharvest fruits and vegetables to control the quality degradation and prolong the shelf-life. Current precooling methods include room cooling, forced-air cooling, hydrocooling, vacuum cooling, contact or package icing, and cryogenic cooling, all of which have their advantages and disadvantages. The first two methods with the cooling medium of air are extensively used because of the wide applicable range of fruits and vegetables. Numerous studies have been devoted to cope with the drawbacks of these two air-based precooling methods with various evaluation criteria and optimization methods. A systematic literature review on these studies is firstly conducted with respect to experimental and numerical investigations respectively for the two methods. The main contributions from the previous studies are also summarized respectively with the research objectives and performance metrics. The literature review indicates that the current performance evaluation is limited to apparent parameters and the optimal design is only proposed based on the performance evaluation and comparison. Furthermore, with inspiration from the research in other domains, a scheme of advanced evaluation and optimization for air-based precooling methods is proposed with thermodynamic evaluation metrics and constructal optimization methods from the interdisciplinary perspective.
