Study on the heat preservation effect of “four-in-one” rural energy ecological model in the north of China
摘要
Abstract
In this paper, "Four in One" ecological model of rural energy is taked as study object, the heat preservation effect of which through measuring the temperarure in December and Janunary was analyzed.The results showed that the temperature indoor increase obviously in sunny days,the quickest temperature increase may be 5-9℃ each hour. In cloudy day, the lowest temperature in the room is about -1 ℃ in early morning ,which is lower than the minimum growth temperature of the common crops. Through the analysis of accumulated temperature in January, activity accumulated temperature of 0℃ was 299.7 degree,and 10℃ was 199.7 degree, the effective accumulated temperature of 0℃ was 299.7 degree and 10℃ only reached 49.7 degree. In the greenhouse the hight-est ground temperature was 23℃ and the lowest temperature may reach 5℃. The average ground temperature of 10 cm and the 30 cm was 11℃, 13℃ respectively, the ground temperature of other depths are between them, relative humidity in greenhouse was above 65%, the humidity could maintain above 80% in the sunny day. Through the analysis showed that it is suitable for planting cold resistant crops in this period,in this greenhouse.关键词
