Superheat r22 chart.

May 26, 2023 · PT charts are most often used for three purposes: to set a coil pressure so that the refrigerant produces the desired temperature, to check the amount of superheat above the saturated vapor condition at the outlet of the evaporator and to check the amount of subcooling below the saturated liquid condition at the end of the condenser. R-134A replaced R-12 for automobile air conditioning systems. R-410A is currently being phased in for residential use as the phase period for R-22 draws nearer.

The water temperature of 212°F (100°C) is the sensible heat. The heat that causes a change of state (water to vapor) with no change in temperature is called latent heat. Latent heat does not affect the temperature. The sum of the sensible and latent heat of the air is called enthalpy or total heat.These charts are an example of a generic superheat charts for a typical fixed orifice, split res-idential system.
