摘要
对连栋温室内简易内保温幕保温节能研究结果表明,使用简易内保温幕初冬时节可使供暖设施启动时间推延14d左右,早7:0 0平均气温提高2 .6 5℃,比双层充气膜温室约节煤6 2 5 0 .5 g/m2 ,节能率达38.2 4 % ;启动供暖设施后可使温室内早7:0 0平均气温提高2 .16℃,比阳光板温室约节煤70 g/m2 ·d ,节能率为11.84 %。简易保温幕降低了试验开间内光照度。
The temperature and energy saving in multi span greenhouse with simple inside thermal screen was studied.The results show that the simple thermal screen can postpone the time of starting up heating facilities for about 14 days in early winter,increases the temperature by 2.65℃ at 7:00 in comparison with the double inflated plastic greenhouse and saves 6250.5g/m 2·d coal,with the energy saving rate of 38.24%.After starting up the heating facilities,the simple thermal screen increases the temperature by 2.16℃ at 7:00 in comparison with the PC greenhouse and saves 70g/m 2·d coal,with the energy saving rate of 11.84%.In the greenhouse with the simple thermal screen,the illumination decreases,better than that in the double inflated plastic greenhouse and PC greenhouse.
