摘要
为提高冬季日光温室保温蓄热性能,研究设计了一种新型主动储放热组装结构日光温室,在河北、内蒙古、宁夏地区冬季严寒时段对温室的环境性能进行实际测试。结果表明:测试地区温室内日平均气温、日最低气温平均值分别在15.0~21.0℃和9.0~17.7℃,白天室内气温大于15℃的平均时长均超过7 h;夜间日平均气温、室内外温差的平均值分别在12.1~18.4℃和18.7~33.8℃。在无其他辅助加温的条件下,新型主动储放热组装结构日光温室保温蓄热性能良好,适用性强,能够满足喜温作物冬季生产需求。
In order to improve the thermal insulation and heat storage performance of solar greenhouses in winter,this study designed a new type solar greenhouse with assembly structure for active heat storage and release,and actually tested the environmental performance of this greenhouses in the cold period of winter in Hebei,Inner Mongolia,and Ningxia regions.The results showed that the average daily temperature and mean value of daily minimum temperature in greenhouse at tested regions were 15-21℃and 9.0-17.7℃,respectively.The average duration of daytime when indoor temperature greater than 15℃all exceeded 7 h.And the daily average temperature at night and average value of indoor and outdoor temperature differences were 12.1-18.4℃and 18.7-33.8℃,respectively.In absence of the other auxiliary heating conditions,the new type solar greenhouse with assembly structure for active heat storage and release has good thermal insulation and heat storage performance,strong applicability,and can meet the winter production needs of prefer warmth crops.
