以太阳能集热器为辅助加温方式,采用了对比试验的方法,研究了太阳能辅助加温系统对生态温室内气温和地温的影响。经连续试验,应用该系统加温区域平均气温较非加温区域高1℃,平均地温高4.2℃。结果表明:生态温室太阳能辅助加温系统具有明显增加地温的效果,且散热管埋深越深抵抗不良天气因素能力越强,具有长期蓄热的能力。
Taking the solar collector as an auxiliary heating method, a comparative experiment method was adopted to study the influence of the solar assisted warming system on the air temperature and the ground temperature in the ecological greenhouse. After continuous testing, the average temperature in the heating area of the system is 1 ℃ higher than that of the non-heating area and the average ground temperature is 4.2 ℃. The results show that the solar assisted warming system has the obvious effect of increasing the ground temperature, and the deeper the depth of the heat pipe is, the stronger the capability of resisting the bad weather is and the longer the heat storage capacity is.
