Solar Heating Performance Results for a Transwall Test-Prototype System

摘要

The preliminary results of thermal performance for a Transwall passive solar heating system in a passive test room are presented. These results are compared with the simultaneously measured thermal performance of a Trombe wall structure in an adjacent test room. The results include operating modes with and without night insulation and for both a vented and unvented Trombe wall. In all cases the thermal performance of the unvented Transwall equalled or exceeded the corresponding performance of the Trombe wall under the conditions described. The construction of the experimental prototype Transwall modules is described. Light transmission through the modules and thermal stratification within the modules is also discussed.
