摘　　要：为了提高北方地区冬季日光温室内的温度,满足作物生长需求,同时减少温室加温能耗,设计了一种水循环增温蓄热系统。该系统以日光温室墙体结构为依托,以水为介质进行热量的蓄积与释放,利用冬季晴天时北墙部位的太阳辐射热量使水增温,并把水储存在蓄热水箱内;夜间温室内温度降到一定程度时,利用所贮蓄的热量给温室加温。结果表明,应用该系统可使温室每天平均气温提高3.65℃以上,地温提高2.00℃左右;夜间气温至少提高3.00℃,地温提高1.00℃以上;既能有效地提高温室温度满足作物生长需求,还能替代化石燃料的使用而减少CO、CO2、SO2、NOx等有害气体的排放量;冬季3个月产生环境效益2.8万元。In order to increase indoor temperature of solar greenhouse in winter in the Northern region, meet the need of crop growth, and reduce energy consumption for heating, this experiment designed a water circulation system, which relied on greenhouse wall structure, took water as media to store and release heat. In sunny day time during winter, water was stored in a tank after circuiting and passing by heating device, the solar radiation was absorbed in the system, and at night, when indoor temperature reduced to certain degree, water circuiting and passing by heating device, heat was released to greenhouse and the air temperature was increased in the solar greenhouse. The results indicated that application of this system could increase the everyday air temperature in greenhouse by over 3.65 ℃, and the ground temperature increased by about 2.00 ℃ ; the air temperature at night in greenhouse was at least increased by 3.00 ℃, and the ground temperature increased by over 1.00 ℃. So this water circulation system could not only effectively raise room temperature to satisfy the requirement for crop growth, but also substitute the utilization of fossil fuel, thus reduce the emission of CO, CO2, SO2, NOx, etc. harmful gas, during 3 months winter season, when 280 000 yuan of environment effect were obtained.
