A multizone air handler provides air to several zones. One interior zone contains computer equipment with only a sensible load. The coil in the unit cools air from 85 F (29 C) db and 70 F (21 C) wb to 53 F (12 C) db and 90% relative humidity (RH). (a) If the zone is to be maintained at 75 F (24 C) and 50% RH, what proportion of the supply air to the zone bypasses the coil? The amount of air supplied to the zone is 2,500 cfm (1.18 m3/s). (b) What is the cooling load for the zone? Assume standard sea-level pressure.

Calculate the condensation rate of the moisture (kg / h) and the flow rate of the air drawn from the outside.arrow_forwardneed help. air conditioningarrow_forwardPick the right combination of True Statements. 1. As the by-pass factor (BPF) of the cooling coil increases, temperature difference between air at the outlet of the coil and coil ADP decreases. 2. As the by-pass factor (BPF) of the cooling coil increases, temperature difference between air at the outlet of the coil and coil ADP increases. 3. During cooling and humidification process, the enthalpy of air may increase, decrease or remain constant depending upon the temperature of the wet surface. 4. During sensible cooling of air, dry bulb temperature decreases but wet bulb temperature remains constant 5. The sensible heat factor for a sensible heating process is 1.0arrow_forward
- Pls. Answer thank you!Atmospheric air from the inside of an automobile enters the evaporator section of the air conditioner at 1 atm, 27 C and 50 percent relative humidity. The air returns to the automobile at 10 C and 90 percent relative humidity. The passenger compartment has a volume of 2 m3 and 5 air changes per minute are required to maintain the inside of the automobile at the desired comfort level. Sketch the psychrometric diagram for the atmospheric air flowing through the air conditioning process. Determine the dew point and wet bulb temperatures at the inlet to the evaporator section, in 8 C. the required heat transfer rate from the atmospheric air to the evaporator fluid, in kW. the rate of condensation of water vapor in the evaporator section, in kg/min.arrow_forwardThe following data refer to summer air conditioning of a building: Outside design conditions 43 °C DBT, 27 °C WBT Inside design condition 25 °C DBT, 50% RH Room sensible heat gain 84000 kJ/h Room latent heat gain 21000 kJ/h BPF of cooling coil 0.2 The return air from the room is mixed with the outside air before entry to cooling coil in the ratio of 4:1 by mass.
