Psychrometric properties of air refer to the physical and thermodynamic properties of moist air, such as dew point temperature, wet bulb temperature, relative humidity, humidity ratio, and enthalpy. These properties are critical in heating, ventilation, and air conditioning (HVAC) and meteorology because they affect the performance and design of HVAC systems, as well as weather forecasting and climate modeling. Accurate estimation of psychrometric properties is essential to ensure efficient and effective system operation, as well as to predict weather patterns and climate phenomena.
