| Abstract:
Three dynamic simulation models for calculating the greenhouse climate and its energy requirements for both heating and cooling were compared by making detailed computations for each of seven sets of data. The data sets ranged from a cold winter day, requiring heating, to a hot summer day, requiring cooling. On the whole, the models agreed in regard to calculated air temperature, humidity, and heating requirements. Significant differences were found between the estimates of fan-and-pad (evaporative) cooling, and the estimated daily amounts of transpiration. These differences appear to be related to the manner in which each model simulated the internal air exchange and the stomatal conductance for transpiration. This report is the conclusion of an effort by a working party consisting of the authors, assisted by advice and comments of other ISHS members. | |
