Air is cooled and dehumidified at constant pressure as shown in the figure below. Heat removed by the cooling coil is 130kW. Find air mass flow rate, air volumetric flow rate, condensation flow rate and sketch al states in a psychrometric diagram . Use AirH20 as the working fluid PLEASE NOTE: T2 has a typo, it should be 16.7 degrees Centigrade, not 16.7 degrees Fahrenheit, and all temperatures should be in Centigrade

Question

Air is cooled and dehumidified at constant pressure as shown in the figure below. Heat removed by the cooling
coil is 130kW. Find air mass flow rate, air volumetric flow rate, condensation flow rate and sketch al states in a
psychrometric diagram . Use AirH20 as the working fluid

PLEASE NOTE: T2 has a typo, it should be 16.7 degrees Centigrade, not 16.7 degrees Fahrenheit, and all temperatures should be in Centigrade

The diagram illustrates a cooling and dehumidification process. 1. **System Overview:** - A chamber features cooling coils at the top. - Air enters the system at point **1** with an initial temperature (\(T_i\)) of 39°C and a relative humidity (\(\phi_1\)) of 50%. 2. **Cooling Process:** - As the air passes over the cooling coils, it is cooled to a lower temperature (\(T_2\)) of 16.7°F (-8.5°C), as indicated at point **2**. - During cooling, the air's relative humidity increases to 100% (\(\phi_2\)). 3. **Condensation:** - The air reaches a state where it can no longer hold all the moisture, resulting in the formation of condensate. - The condensate droplets collect and fall under the influence of gravity. 4. **Pressure and Removal:** - The process occurs at a pressure of 101.3 kPa. - The condensate is then removed from the system at a temperature of 16.7°C. This setup can be typically found in air conditioning or refrigeration systems where humidity control is required.
