By pass factor of the cooling coil = 0.2

The return air from the room is mixed with the outside air before entry to the cooling coil in the ratio of 3:1 by mass If 20 $m^3/min$ of fresh air is supplied find:

i) Condition of air leaving the coil,

ii) Capacity of cooling coil in TR,

Locate point 'a' $40^o$ C DBT and 50% RH and point 'b' $26^o$ C and 50% RH and point 'd' $10^o$ C and saturated condition on psychrometric chart. then locate the point 'c' in such a way

$ac/bc=3/1$

join c and d then locate point 'e' in such a way that

$de/dc=0.2$

i)condition …
