Question

In an air conditioning system 30 cmm of fresh out door air is introduced at 43°C Dbt

and 30% RH. The remaining air is recirculated from the room maintained at 25°C DBT and 50% RH. The bypass factor of cooling coll is 0.15 and apparatus dew point is 11.8°C, RSH = 100 kW and RLH= 15 kW. Determine:

(1) Humidity ratios for outdoor and Room conditions.

(Ii) OASH & OALH

(iii) ERSH and ERLH
