- Abstract:
- 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.
