Air Lite Psychrometric Calcs: A Must-Have App for HVAC Engineers

Air Lite Psychrometric Calcs is a free Android application developed by Cold Means Mobile Software LLC. It is a psychrometric calculator designed for HVAC engineers, designers, technicians, commissioning agents, and maintenance personnel. The app supports both SI and IP units, making it versatile for use in different regions.

The app is easy to use and provides accurate calculations for various properties including wet bulb temperature, relative humidity, dew point temperature, atmospheric pressure, barometric pressure, enthalpy, humidity ratio, density, specific volume, and vapor pressure. The calculations are based on the American Society of Heating Refrigeration and Air Conditioning Engineers (ASHRAE) Fundamentals 2009 ideal gas equations.

To use the app, you need to input the altitude and dry bulb temperature, and either the wet bulb temperature, relative humidity, or dew point temperature. The app defaults to using the wet bulb as the humidity input if more than three properties are filled. However, you must hit the clear button in between calculations. Overall, Air Lite Psychrometric Calcs is a must-have app for anyone in the HVAC industry who needs to make accurate calculations on the go.
