## Description

HVAC PT Chart is an electronic pressure-temperature calculator that allows HVAC technicians and contractors to quickly lookup the temperature and corresponding pressure for 125+ common HVAC refrigerants.<br><br>This is a unique PT Chart app for the following reasons:<br><br>1. Includes 125+ refrigerants (Dew and Bubble versions)<br><br>2. Allows you to input the exact temperature and then the corresponding pressure will display and vice versa.<br><br>3. Allows you to also use a slider control to specify the exact pressure or temperature (in 1 degree increments) to see the corresponding temperature or pressure<br><br>4. Allows you to select the atmospheric pressure so as to show the true pressure-temperature relationships even for high elevations like Denver, Colorado.<br><br>5. Includes a database of 1000+ cities world-wide with elevation data that is used to derive atmospheric pressure<br><br>6. Includes ability to display all important thermodynamic properties about each refrigerant<br><br>7. Display units in both English and Metric<br><br>8. Allows you to email your inputs and results
