The following data relate to an air-conditioned space: Outer condition - $38^{\circ} \mathrm{C}$ DBT, $50 \% \mathrm{RH}$ Room condition - $24^{\circ} \mathrm{C}$ DBT, $50 \% \mathrm{RH}$ Sensible heat load ...... 24 kw Least heat load - 6kW By-pass factor of the cooling coil 0.16 If the ventilation requirement is such that on mass flow rate basis 20 percent of fresh air is introduced and 80 percent of supply air is recirculated, determine: (a) Supply air flow rate;
Explanation
To find the supply air flow rate, we need to calculate the total heat load and then use the given by-pass factor and ventilation requirement to find the supply air flow rate.
