These three UPDATED HVAC quick reference polystyrene cards are double sided and designed to be used with Air Conditioners and Heat Pumps to measure the refrigerant charge level in a unit, charge refrigerant, troubleshoot refrigerant based problems, and measure heat transfer to determine if there is a problem.
- Use the P/T Chart to find the Saturated Temperature of the common refrigerants R-32, R454B, R-410A, R-22, R-407C, R-422B, and R-438A.
- Use the Guide to determine how to find the Bubble and Dew Saturated Temps of Blend Refrigerants.
