THE SUNSPACE : COMPUTATION AND IN-SITU MEASURES

摘要

Today, it is not necessary to further demonstrate the interest of knowing with good accuracy the temperaturernevolution in a non-heated greenhouse.rnSince over and underheating are predicted, we can evaluate for every greenhouse its utilization period for therninhabitants arid for the plants, and its impact on the heating demand of a house.rnThe program "SOLPA I" evaluates separately the convection and the interior radiation contribution, taking a non uniform distribution of solar radiation and successive reflexions into account. It also allows us to visualise the evolution of heat storage in the opaque walls during the day, arid of heat emission during the night.rnThe results obtained by the simulation are compared with the measures made in a particularly interesting sunspace and in an experimental cell.
