Ambient air enters a cooling coil at 24°C db-temperature and 50% relative humidity with a dry air mass flow rate of 0.9 kg/s. The air leaving the cooling coil at 9°C is reheated to 13°C and 70% relative humidity. The pressure is constant at 101.3 kPa. Determine: the dew-point of the ambient air in °C the rate of moisture removal in the cooling coil in kg/s the refrigeration capacity of the cooling coil in kW the heat input rate of the heating coil in kW
