辽宁省现有水果贮藏库绝大多数为半地下式库,贮藏期间靠开闭门窗利用自然冷源调节库内温度,往往因通风掌握不好,造成库内温度过高或发生冷害。为适应果品生产发展的需要,做到季产年销,现有半地下式贮果库亟待改造。辽宁省供销社科研所与沈阳劲松机械厂协作研制了自然冷源自动控制通风调节装置,在沈阳市果品公司沈东仓库 Most of the existing fruit banks in Liaoning Province are semi-underground libraries. During the storage period, the temperature inside the library is controlled by using natural cold sources during opening and closing, which often leads to the overheating or cold damage in the interior due to poor ventilation. To meet the needs of the development of fruit production, annual sales to achieve the season, the existing semi-underground storage of fruit urgent reform. Supply and marketing cooperatives in Liaoning Province Institute of Science and Technology and Shenyang Jinsong Machinery Factory developed a natural cold source of automatic control of ventilation regulation device in Shenyang City Fruit Company Shen Dong warehouse
