How does the psychrometric chart aid in air conditioning system design?

The psychrometric chart enables engineers to analyze the properties of air to be conditioned and determine the required air conditioning effect. By plotting the initial and final conditions of the air on the chart, engineers can visualize the changes in temperature, humidity, and enthalpy, and select the appropriate equipment and control strategies to achieve the desired air conditioning effect. This graphical representation simplifies the complex calculations involved in air conditioning system design and analysis.
