Q2/ In one of applications, wanted to conditionlaboratory at inside design condition DBT-24 Â°C and 50% Rh andoutside design condition DBT-44 Â°C and WBT-27 Â°C. Total sensibleload for the space is 35 kW and total latent load for the space is19 kW. Rate of supplied air to the space is 11050 m'/hr and rate ofoutside ventilation air is 4250 m/hr. The recireulated air ismixing with the outside air and then entering to cooling coiland leaving at 95%Rh then the air is passing through heating coil before supply tothe space. Determine: 1.Condition of supply air to the conditionedspace (DBT & RH): 2.Condition of air before and after coolingcoil (DBT & RH); 3. Sensible load of heating coil; 4.Sensibleload and latent load and total load of cooling coil: 5. Apparatusdew point (ADP) for the cooling coil; 6. Draw the cycle on thepsychrometric chart.
