Slab Preprocessors in Energyplus
I am quite confused about the "evapotranspiration model" and "ZCLREANCE: Distance from bottom of slab to domainslab bottom edge of the area that will be modeled with the grid system" in the slab preprocessor. I found that those two variables has a large effect on the ground surface temperature.
so I just wondering that:
- when should we use evapotranspiration model (or when should not use it)?
- How to calculate the ZCLEARANCE in stead of using the default value 15m?
@Constance Could you state what version of E+ you use? Also could you elaborate on what is your aim of using the Slab Preprocessors?
Thanks for you reply! It is E+ version 2.13. I am trying to use the slab preprocessors to get the ground temperatures for each month. I need accurate ground temperatures as I will compare the simulated and measured indoor temperature at the end.
@Constance Are you aware that the current E+ version is 8.8? Can you upgrade?
Sorry, My mistake. it's the E+ lastest version 8.8.0.
