I am trying to find the cooling(TR) and heating (KW) for a fresh air unit supplying 100% fresh air to multiple rooms in the same floor.
I have calculated the room loads in normal way and i am using the same dehumidified CFM as the required fresh air quantity to different rooms, is it okey? Total de-hum cfm for rooms is 955 cfm and i want use a single customized tfa unit of 955 cfm for supplying to different rooms. I need to find the TR and Heating KW for the unit.
Conditions are:
