摘  要：
以内保温日光温室为研究对象,在日光温室后墙(37墙)加装间距0.4 m的水管(直径0.1 m、长3 m)共28根,蓄热水管总体积0.66 m~3,研究蓄热水管对日光温室热环境的影响。结果表明:日光温室加装蓄热水管后,晴天时温室内最低气温可提高2.3℃,阴天时提高0.6℃,后墙距墙体内表面0、10、20 cm处最低温度均高于对照,墙体的保温性能明显增强。1月试验区最高气温、最低气温及平均气温分别提高了5.22、0.71、1.36℃。连续不良天气(3 d)条件下,加装蓄热水管能将日光温室土壤(20 cm)日最低温提高2.6~3.1℃;连续晴天(3 d)条件下能提高2.0~3.7℃。可见,加装蓄热水管明显地改善了温室内的热环境,提高了日光温室的太阳能热利用率。

摘  要：
Taking the inner thermal insulation greenhouse as research object,this paper installed 28 water pipes(diameter 0.1 m,length 3 m,spacing 0.4 m)in the back wall(37 walls)of solar greenhouse,with 0.66 m3 total volume;and studied the effect of heat-accumulated water pipe on thermal environment of solar greenhouse. The results showed that after installation,on a sunny day,the lowest temperature in greenhouse was increased by 2.3 ℃;on a cloudy day,the lowest temperature in greenhouse was increased by 0.6 ℃. The lowest temperatures at 0 cm and 20 cm inside wall of solar greenhouse were higher than that of the contrast area. The thermal insulation properties of the wall were obviously enhanced. In January,the maximum temperature,minimum temperature and average temperature of the test area were 5.22,0.71 ℃ and 1.36 ℃ higher than that of the contrast area. Under continuous(3 days)adverse weather conditions,the daily soil(20 cm)minimum temperature of solar greenhouse was increased by 2.6-3.1 ℃;and under continuous sunny condition(3 days)the daily soil(20 cm)minimum temperature of solar greenhouse was increased by 2.0-3.7 ℃. Visibly,installation of heat-accumulated water pipe could significantly improve the thermal environment in greenhouse,thus the solar energy efficiency of heat utilization in greenhouse was raised.
