<p>A design process is laid out for sizing cooling and heating system capacity; for specifying the airflow and duct sizes to each conditioned space; and for specifying the free area needed to transfer air supplied to closed rooms back to the central return. The software program <a href="http://www.elitesoft.com/web/hvacr/elite_rhvacw_info.html">RHVAC</a> (from <a href="http://www.elitesoft.com/web/hvacr/elite_rhvacw_info.html">EliteSoft</a>) and additional calculations are used to establish this process. An actual builder's plan is used as an example of the design process.</p>
