摘　　要：如何利用自然冷源一直都是热点话题。季节性土壤蓄冷目前在舒适性空调领域已经有了相关的应用案例,但冷链物流的温度都一般都在0~5℃或-18℃,空调的系统温度一般难以满足其要求,因此在冷链物流方向的应用还是较少。在冷链物流的各个环节中,果蔬等农产品采摘后的预冷是全程冷链的第一步也是关键一步,但由于其耗能较大,源头地缘限制等因素导致其不能大面积铺开,造成食品在冷链中出现腐烂和过熟。本文基于土壤蓄冷构造了一种新型的果蔬预冷方案,探讨其节能效果。How to utilize natural cold sources has always been a hot topic.Currently,seasonal soil cooling storage has been applied in the field of comfort air conditioning,but the temperature of cold chain logistics is generally O-5C or-18C,and the system temperature of air conditioning is generally difficult to meet its requirements.Therefore,there are still few applications in the direction of cold chain logistics.In all aspects of cold chain logistics,precooling of agricultural products such as fruits and vegetables after harvesting is the first and key step in the entire cold chain.However,due to its high energy consumption,geographical constraints at the source,and other factors,it cannot be spread in a large area,resulting in food decay and over ripening in the cold chain.In this paper,a new type of precooling scheme for fruits and vegetables based on soil cold storage was constructed to explore its energy-saving effect.
