Hi All,<br>I'm trying to figure out exactly what the values listed on report SV-A for heat extraction and addition rate represent. For a VAV reheat system, I understand that "Heating Capacity" is the capacity of the terminal heating equipment, which includes the heat required to make up for the following:<br>
<br>envelope losses (including infiltration)<br>ventilation air<br>reheating of the supply air<br><br>I am unclear as to what the "extraction rate" and "addition rate" represent. The help states that the addition rate is the rate of heat addition at design conditions, but the addition rate listed in my reports is almost half the heating capacity for all spaces. It seems that if the addition rate is listed for design conditions, then the addition rate should be close to the heating capacity. Can anyone shed some light on the subject?<br>
<br>Thanks in advance,<br><br>--<br>Karen
