摘　　要：以拉萨市某温室为例,提出一种新的热平衡分析方法,通过建立数学模型计算温室热量得失,对比分析得出温室供热期间太阳辐射的热量是其最小耗热量的2~3倍,结合经济效益分析,确定了土壤蓄热与电加热结合的供热方式。采用该供热方式与采用直接电加热供热相比节能69.6%以上,经济效益明显。此温室内热平衡分析方法对温室供热设计具有较高价值。Taking a greenhouse in Lhasa as an example,and proposes a new method of thermal equilibrium analysis.The mathematical model was used to calculate the heat gain and loss of the greenhouse.The comparative analysis showed that the solar radiation gain during heating of the greenhouse was 2-3 times,combined with the economic benefit analysis,the heating mode combining soil heat storage and electric heating was determined.Compared with the direct electric heating,the energy saving was more than 69.6%,and the economic benefits were obvious.This analysis method of heat balance in the greenhouse has high value for the heating design of the greenhouse.
