Question:-
For an air-conditioned space, RTH = 100 kW, RSHF = 0.75, volume flow rate = 100 m3/min, and indoor design specific humidity is 0.01 kg/kg of dry air. What is the specific humidity of the supply air?
Option (A)
0.010
Option (B)
0.0075
Option(C)
0.005
Option(D)
0.0025
Correct Option:
(C)
Question Solution:
RSHF = (RSH/RTH)
\ RSH = 0.75 x 100 = 75 kW
RLH = 100 – 75 = 25 kW
25 = (100/60) x 1.2 (wL - wS) x 2500
\ wS = 0.005
