TRANSIENT HEAT-TRANSFER THROUGH INSULATED WALLS

The designs of heating and cooling systems are typically based on heat transfer under steady-state conditions. In desert regions, however, t here are large changes during a 24-hour period and the steady-state ap proach becomes inapplicable. An analysis of transient heat transfer th rough insulated walls is presented for three different cases. The resu lts indicate that cooling loads for buildings are smaller for insulati on placed on the outdoor facade than for insulation placed on the indo or facade.
