通过对自然通风库进行双控(控温控湿)和双能源(自然冷源和电能)改造设计，研究了自然冷源通风库的节能效果和对红富士苹果贮藏品质的影响。结果表明，红富士苹果贮藏中期(12月上旬至翌年2月中旬)，可以依靠自然冷源进行库温和果实品温控制，库温和果温控制在-1.0～-0.7 ℃，较完全制冷库节能22.5% 。贮藏期间红富士苹果果实硬度、可溶性固形物含量和可滴定酸含量较完全制冷库贮藏果实略有降低，但差异不显著。

By fixing the ventilation system in small assembled cold room， the energy-saving effects of ventilation of natural cool source and their impect on the quality of apple storage were studied . The results showed that in the cold season(from the early December to the next mid-February)， the temperature of cold room and apple cold keep-1.0~-0.7 ℃， only by ventilation system. Compared with storage only by mechanical refrigeration， the energy consumed in apple storage by mechanical refrigeration assisted by ventilation system decreased by 22.5%， and the decrease of fruit firmness， the soluble solid content and the titratable acid content of apple was not significant .
