When we use PT charts on refrigerants with glide, we must understand exactly what dew point and bubble point are. The dew point marks the first change from vapor to liquid, and the bubble point marks the first change from a liquid to vapor. In the case of a refrigerant like R-407C, the difference between dew and bubble point is significant.This app can calculate a simple pressure/temperature relationship or calculate superheat/subcool temperatures. The user can input pressure or temperature (s) on any screen and the other values are automatically calculated and displayed.
