摘  要：
针对传统日光温室普遍存在的冬季室内采光不够、夜间温度过低的问题,对杨凌地区2座传统日光温室进行了基于主动采光和相变蓄热技术的改造。以当地未改造的日光温室为对照,研究了2座改造温室在不同典型晴天、阴天和雪天天气条件下的光照及空气温湿度的变化情况。结果表明:主动采光温室的光照强度在典型晴天较对照温室可提高6 197lx,采光率提高46.8%,平均气温提高2.7℃,降低温室夜间湿度10.53%,典型阴天和雪天可降低夜间湿度7.94%。相变蓄热温室典型晴天夜晚气温可比对照温室高3.5℃,湿度相对降低8.42%,阴天和雪天夜间气温比对照高2℃左右,湿度比对照低3.40%。因此,通过2种技术改造的日光温室均有良好的效果,为传统日光温室的改造提升提供了有效途径。

摘  要：
In order to solve the problem of insufficient indoor lighting and low temperature during the cold season in the solar greenhouse,the two traditional solar greenhouses of Tangjiacun in Yangling district had been carried out active lighting and phase change heat storage technology transformation.The changes of environmental parameters such as temperature,humidity and light under different weather conditions were studied,and the untreated solar greenhouse was used as the control.The results showed that the active lighting greenhouse in sunny day could improve the indoor light intensity of about 6 197 lx compared with the control greenhouse,increase lighting rate by 46.8%,increased the average temperature of 2.7 ℃ and reduced the greenhouse nighttime humidity 10.53%.In cloudy or snowy days it could reduce the nighttime humidity by 7.94%.The phase change heat storage greenhouse in sunny night could be higher the temperature 3.5 ℃than control,decreased the relative humidity 8.42%.In cloudy and snowy days the temperature it was about 2 ℃ higher than the control,and the humidity was 3.40% lower than the control.Therefore,greenhouse which had been through the two kinds of technological transformation had a good effect of heat preservation and heat storage,and these two technologies would provide an effective way for the upgrading of traditional solar greenhouse in the future.
