An air-conditioning system is to take in outdoor air at 15 °C and 30 percent relative humidity at a steady rate of 35 m³/min and to condition it to 30 °C and 60 percent relative humidity. The outdoor air is first heated to 27 °C in the heating section and then humidified by the injection of hot steam in the humidifying section. Assuming the entire process takes place at a pressure of 100 kPa, determine (a) the rate of heat supply in the heating section and (b) the mass flow rate of the steam required in the humidifying section (c) What happen if the dry bulb temperature of State 3 reduce to a certain temperature where the RH will be 100% ? And please state the process . Please write down how did you get the value with Psychrometric. Please print out and attached with the answer. 15 °C T₁= 15 °C $₁ = 30% v₁ = $₁ = 30% = 35 m³/min N 27 °C Heating coils teeeeeeee Air T₂= 27 °C 2 %09 = Ep 30 °C Humidifier T₂ = 30 °C 103 = 60% 3 An air-conditioning system is to take in outdoor air at 15 °C and 30 percent relative humidity at a steady rate of 35 m³/min and to condition it to 30 °C and 60 percent relative humidity.
