There had to be a replacement for the Ozone damaging refrigerants of the past and the successor was the HFC R-404A that we all know of today. 404A’s reign however was short lived.

SUPERHEAT To determine subcooling for R-401A, R-404A, R-407A, R-407F, and R-408A, use BUBBLE POINT (temperatures above 50°F) To determine superheat for R-401A, R-404A, R-407A, R-407F, and R-408A, use DEW POINT values (temperatures 50°F and below) Pressure (psig) • Vacuum (Inches of Hg) - Italic Figures Form 1A / 82012

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.
