Part 1 of this article covered how to calculate total temperature glide, effective temperature glide, fractionation, average evaporator and condenser temperature, evaporator superheat, and condenser subcooling for refrigerant blends that have a temperature glide. This article will offer a quick review of evaporator superheat and condenser subcooling calculations, then create a scenario where a service technician chooses the incorrect dew and bubble point value from the pressure/temperature (P/T) chart when calculating evaporator superheat and condenser subcooling.
