The fresh air is supplied through a dedicated outdoor air system with fresh air ducts and separate fresh air diffusers in each zone. While modeling in Equest, i have created the DOAS system. For each VRF system type modeled, i have specified the DOAS system. Now while entering the zone details under each VRF system type, i have a small confusion.</div><div id="yui_3_16_0_ym19_1_1493191546267_2542"><br></div><div id="yui_3_16_0_ym19_1_1493191546267_2542">Under the outdoor air tab, i will enter the outdoor air flow CFM provided by the fresh air diffuser in each zone. But when entering "design flow" cfm under "air flow" tab, do i have to enter only VRF supplied design air flow or add the design air flow + outdoor air and enter the total airflow in the zone. </div><div id="yui_3_16_0_ym19_1_1493191546267_2542"><br></div><div id="yui_3_16_0_ym19_1_1493191546267_2542">If i add, will Equest understand that outside air part is cooled by the DOAS and only (Total - OA) should be cooled by the VRF system?</div><div id="yui_3_16_0_ym19_1_1493191546267_2542"><br></div><div id="yui_3_16_0_ym19_1_1493191546267_2542">Please clarify.</div><div id="yui_3_16_0_ym19_1_1493191546267_2542"><br></div><div id="yui_3_16_0_ym19_1_1493191546267_2542">Regards,</div><div id="yui_3_16_0_ym19_1_1493191546267_2542">Rathnashree</div></div></body></html>
