The Cards

These three HVAC quick reference polystyrene cards are double sided and designed to be used with Air Conditioners and Heat Pumps to measure the refrigerant level in a unit, charge refrigerant, troubleshoot refrigerant based problems, and measure heat transfer to determine if there is a problem.
 

  • Find the Target Subcooling to measure the refrigerant level of systems with a TXV metering device​

  • Use Subcooling to determine if a system is undercharged, correctly charged, or overcharged

  • Find the Target Superheat to measure the refrigerant level of systems with a fixed orifice metering device

  • Use Total Superheat to determine if a system is undercharged, correctly charged, or overcharged

  • Use Delta T to determine if the system is exchanging heat properly

  • Use the P/T Chart to find the Saturated Temp of 5 common refrigerants

  • Use the Guide to determine how to find the Bubble and Dew Saturated Temps of Blend Refrigerants

  • Use the Refrigerant Weight Chart to calculate the amount of refrigerant needed per foot of tubing

  • Use the Guide to weigh in the full or partial refrigerant charge into an empty vacuumed unit
