利用自然冷源的蔬菜贮藏装置设计与适用区域

Design and Applicable Region of Vegetable Storage Device Using Natural Cold Source

在我国的华北、东北和西北地区春冬季气温较低且持续时间长,有着很大的自然冷源蕴藏量,可以用于蔬菜的贮藏。本文介绍了利用自然冷源贮藏蔬菜的装置及其适用区域,主要包括适用于家庭的小型蔬菜贮藏装置和与冷库结合使用的大型蔬菜贮藏装置。分析表明:小型蔬菜贮藏装置通风效果好,利用室外冷源或室内热源,节约能源,提高蔬菜贮藏品质;大型蔬菜贮藏装置与冷库结合使用,在我国东北、西北地区气温较低、冬季较长的区域,可利用室外空气循环降温的时段较长,节能与环保效果显著。

A lot of natural cold energy, which was appropriate cold resource for storing vegetables, reserved in the north, northeast and northwest regions of china, because the temperature in spring and winter was lower and lasted longer than other regions. Emphasis was put on two kinds of equipment of storing vegetables by natural conditions in the article, one was small vegetable storage equipment suitable for family and the other was large vegetable storage equipment. Analysis showed that small vegetable storage equipment which used indoor heat to prevent freezing ventilated effectively, saved energy and improved the quality of the storing vegetable. Large vegetable storage equipment combined with cold storage. As a result of the low temperature in northeast and northwest regions, it was necessary to add heating facility to cold storage. The winter was long in these districts, then the period of using outdoor air to cool down was long, the effect of energy saving and environmental protection was still considerable.
