Hello guys,

why we use supply air (Leaving air) temperature as "54 degree Fahrenheit"?

What is the RH of the leaving air from the coil?

How cooling coil dehumidify air?

and what is Coil ADP (Apparatus dew point)?
 
Time to review your Psych charts. Typically the 55°F DB/54°F WB relates to a room condition of 75°F and 50% RH.

The coil leaving conditions are saturated, so you can review how many grains of moisture are in the air at the saturated condition and how many grains of moisture were in the air for the entering condition. The excess moisture condenses on the coil and drains out.
 
@ willard3,

Room conditions:

Dry bulb: 75°F and RH: 50%
