For 100% fresh air system , this formula applicable or not ?? Please explain sir....

[@ejazahmedshaikh461]

What is purpose of duct heater? and application sir

[@rafibashanazeerbasha3542]

During winter hot air need. Heater will change cold air to hot air. Based on capacity

[@terryqin5649]

Rafibasha Nazeerbasha You will not be able to rely on this heater to heat your whole space as this heater will only work as a re-heat/pre-heat process so I will say the best application is to reduce energy consumption from your main heating unit.

[@manojgusain28]

sir i am confused about SAT and room temp 75 F and Heating temp. diffuser 90 F why you take SAT 55 please expalin SAT

[@manojgusain28]

[@rafibashanazeerbasha3542]

Assalamualikkum sir, Can u explain me how duct connection will be. I meant electrical connection details for heater

Please confirm sir.

[@pinakyguha7864]

[@saviomathias2158]

Desired Room Temp/RH = 71.6 DEG.F/55% RH AHU Capacity = 15500 CFM Off. Coil Temp = 55.4 DEG.F What will the Heater kW = ? 79 kW is correct? or 71.6deg.F - 15deg.F (as per AHSRARE) = 1.2 delta.T ... so 6kW heater is sufficient?
