The HVAC Utility App is a psychrometric calculator, a system capacity calculator, a ducting heat gain calculator and multiple unit converter all rolled into one! The psychrometric calculator calculates wet bub temperature, dew point temperature, relative humidity and enthalpy. The capacity calculator calculates a system's cooling capacity in Btu/hr using the enthalpies before and after a heat exchanger or coil and the air flow rate (in CFM).. The ducting heat gain calculator calculates the heat gained or lost across a straight duct in Btu/hr. The unit converter converts English and Metric units common to Lengths, Areas, Volumes, Temperatures, Energies, Pressures and Velocities.
Update 1.1: Added Unit Converter for length, area, volume, temperature, energy, pressure and velocity, English and Metric units. Slight graphical tweak.
Update 1.3: Repaired graphical tweak that caused text input boxes to become invisible for some users.
Update 2.0: Added Customization options and streamlined app.
