2) An outdoor air conditioning system with a temperature of 10°C and a relative humidity of 30% receives a stable melody of 45m³ /min and delivers it with a temperature of 25°C and a relative humidity of 60%. Th outside air is first heated to 22°C in the heating section and then hot steam is injected into it in the humidification section. Suppose the whole process is performed at a pressure of 100kPa. It is desirable to specify: A) The rate of heat supply in the heating sector B) The mass flow rate of water vapor required in the dehumidification section Heating coils Humidifier T = 10°C IT = 25°C P1 = 30% Air 103= 60% %3D V, = 45 m/mn T, = 22°C %3D 3.
