HVAC Psychrometric LT is a professional HVAC productivity app for quickly visualizing and calculating air properties on an interactive psychrometric chart. It helps engineers, technicians, and students solve dry bulb, wet bulb, relative humidity, dew point, humidity ratio, and enthalpy with altitude aware accuracy. With a clear interface and fast calculations, it supports on site decisions and efficient HVAC design and commissioning. Core features include an interactive psychrometric chart with zoom and point plotting, a two input solver that computes all remaining air properties, and process modeling for heating, cooling, humidification, dehumidification, and air mixing. Switch between SI and IP units, adjust barometric pressure, and export results for reports. Ideal for HVAC design, building services, energy audits, and classroom training. Keywords include HVAC psychrometric chart, air properties calculator, HVAC design, commissioning, and productivity tool
1. Install and open the app, then choose your unit system SI or IP and set altitude or barometric pressure if needed. 2. Enter any two known air properties such as dry bulb and relative humidity to instantly solve all remaining properties and plot the point on the chart. 3. Add additional state points and edit values to compare conditions, then label points for easy reference. 4. Create processes such as heating, cooling, humidification, dehumidification, or mixing to visualize lines on the chart and calculate loads and moisture changes. 5. Save your project and export a chart image or data report to share with your team or include in documentation
