A) Sensible cooling
B) Cooling and humidification
C) Cooling and dehumidification
D) Adiabatic saturation
Correct Answer: C
Solution :
\[BPF\,\,=\,\,0.1,\,\] \[ADP\,\,=\,\,12{}^\circ C,\] \[DBT\,\,=\,\,38{}^\circ C,\]\[DPT\,\,=\,\,90{}^\circ C,\] BPF for cooling coil \[=\frac{{{t}_{d\,2}}-{{t}_{d\,3}}}{{{t}_{d\,1}}-{{t}_{d\,3}}}\] \[1=\frac{{{t}_{d\,2}}-12}{38-12}\] \[{{t}_{d\,2}}=2.6+12=14.6{}^\circ C>{{t}_{d\,1}}\] Dehumidification rakes place.You need to login to perform this action.
