| Abstract: |
| This paper analyses the calculation behaviors of heat and wet state inside the protected land facilities. The equations of energgy and quality balance for green houses and plastic tents are established. Also, emphasis is given to the calculation method and the expression formula of each component in the equations. The results show that the above method can be used to describe the quan-titive relations among the outside weather conditions, the transparent cover of the protected land, heat supply and ventilating system and the parameters of heat and wet state in the greenhouses and plastic tents. |
