8. A meeting room is to be maintained at 25°C dry-bulb (db) and 18°C wet-bulb (wb) temperatures. The atmospheric pressure is 101.3 kPa. The sensible heat load of the room is 58.6 kW, and the latent heat load is 58.6 kW. The supply air temperature must not be lower than 18°C db. (a) What is the required mass flow rate of the supply air? (b) What is the wet-bulb temperature of the supply air? (c) What is the sensible heat ratio (SHR)?

Step 1
3 kPa - Sensible heat load, \( Q_s = 58.6 \, \text{kW} \) - Latent heat load, \( Q_l = 58.6 \, \text{kW} \) - Supply air temperature, \( T_{supply} \geq 18^\circ C \) --- Show more…

An air-conditioned space is maintained at 25 °C and 50% relative humidity. The outside conditions are 40 °C DBT and 25 °C WBT. The space has a sensible heat gain of 245 kW. The conditioned air is supplied to the space as saturated air at 10 °C. The equipment consists of an air washer such that the air entering it comprises 25% outside air and the remainder being recirculated room air. Calculate: A. The volume flow rate supplied to the space. B. The latent heat gain to the space. C. The cooling load of the air washer.

3 - An air-conditioned space with inside design condition of DBT=25.5 °C WBT=18 °C has a sensible heat gain of 17.5 kW and a latent heat gain of 12.3 kW. The space requires an outside air of 0.35 m³/s at DBT=32.5 °C, RH=50%. Find: a) the state of the supplied air and its mass flow rate, b) the cooling coil load, c) plot the process on the psychrometric chart and calculate the BPF. (Answers: Ts=11.5 °C, h=29.5 kJ/kg, ms=0.813 kg/s, Qcoil=24.8 kW, BPF=0.25)

A space is to be maintained at 22°C and 50% relative humidity. The sensible heat load is 100 kW, and the latent heat load is 15 kW. Outside air is at 38°C DB and 25°C WB temp. Air is supplied to the space at 13°C. If an all-outside air system (no recirculation) is to be implemented, determine: (a) the cooling capacity in tons; (b) capacity of supply air fan in cmh; and (c) the coil bypass factor.
