Abstract
Analyses of underground thermal effects in a hothouse have enabled the formulation of long-term heat conduction model for the Solar Green House, where Solar heat is stored in underground by heat exchangers laid in parallel under the floor of the hothouse.
A long-term characteristic formula for heat conduction was obtained. The formula makes the caluculation of long-term temperature variation in the Solar Green House possible. The results of experiments using an experimental Solar Green House having 200m2 in area proved the validity of the formula.
