Hi friend. I have watched a lot of your videos. Thanks for sharing your excellent HVAC designing knowledge. I have several questions about the ventilation.
1. based on carrier air conditioning system design handbook, it recommend to choose the larger minimum quantity of the minimum cfm per person and cfm per sq ft of floor area, but in your E-20 heat load calculation sheet, they are added together as the minimum ventilation.
2. air change rate is related to the supply air or outside air? If it is related to outside air, does it mean I need to choose the larger minimum quantity among CFM(ACH), CFM(person) and CFM(sqft) as outside air quantity.
or if ACH is related to supply air, then I can directly use CFM(ACH) as the supply air quantity.
