In HVAC engineering, psychrometrics refers to the study of the physical and thermal properties of moist air. This calculator focuses on five key properties: Dry Bulb Temperature, Relative Humidity, Dew Point, Wet Bulb Temperature, Enthalpy, and Humidity Ratio. In real-world applications, engineers typically measure and adjust Dry Bulb Temperature and Relative Humidity using temperature sensors and humidity controllers. The other values Dew Point, Wet Bulb, Enthalpy, and Humidity Ratio are derived from these inputs and help inform system design, comfort control, and energy efficiency strategies.
