cooling coil
cooling coil
(OP)
Hello there
I am facing to following topic.
Very specific, and old post can't help me, unfortunately.
I am dealing with a cooling coil, and volumetric air flow at OUTLET is given to me.
Known data are:
- air inlet temperature
- air inlet relative humidity
- coil capacity
It is a strange problem:
- since air I estimate there will be dehumidification I assume mass flow won't conserve.
Therefore I can't calculate air outlet mass flow and consider it constant.
Any suggestion of how determining inlet volumetric air flow ?
Many thanks !

RE: cooling coil
From conservation of mass, inlet lb/hr = outlet lbs/hr-condensate removed.
If outlet air wet bulb is known, the latent heat removal can be calculated and thus lb/hr of condensate removed.
Otherwise, no unique solution, since outlet wet bulb depends on latent capacity of the cooling coil.
