HVAC P/T Chart 1.0.0

This application serves as a specialized HVAC tool that facilitates the conversion of saturation pressure (PSIG) to saturation temperature (°F). It features a navigable conversion chart for five commonly utilized HVAC/R refrigerants: R22, R410a, R407c, R134a, and R404a. Users can access a comprehensive list of refrigerant saturation pressure and temperature statistics, ranging from -14 °F to 500 °F in degree increments.

Notably, the application provides both dew point and bubble point statistics for refrigerants exhibiting significant temperature glides, adding depth to its utility.

One of the app's primary uses is to assist HVAC technicians in the field who may be working with older manifold pressure gauges that lack an integrated conversion chart for these refrigerants. It serves as a valuable resource for troubleshooting and diagnostic tasks, as well as for completing necessary paperwork.

To utilize this application, simply follow these steps:

1. Launch the OpenHVAC P/T Chart application on your device.
2. Select one of the five refrigerants through the tabs positioned at the top of the application to view its corresponding P/T statistics.
3. Swipe up or down to navigate through the selected refrigerant's P/T chart.

This program was developed to support maintenance departments within hospitals where HVAC work is performed. It serves as an aids for diagnostics during preventative maintenance inspections and assists maintenance personnel in managing their documentation. The observation that many maintenance crews utilize outdated manifolds with limited refrigerant compatibility directed the creation of this tool. This allows technicians to perform necessary conversions on-site and enhances troubleshooting processes over the phone, potentially reducing the need for in-person visits unless absolutely required.

Future updates intend to include additional refrigerants as demand dictates.
