HI,
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:
Please guide me in the calculation.
DB RH WB gr/lb
Room condition (summer) 75 50 61.72 64.61
Room condition (winter) 70 45 57.01 48.3
Ambient condition(summer) 98.6 60 85.86 168.2
Ambient condition(winter) 44.6 45 35.82 19.46
