Last month’s article covered a 400-series refrigerant blend’s total temperature glide, effective temperature glide, fractionation, superheat, subcooling, and average evaporator and condensing temperatures using a pressure/temperature chart. This month’s article will deal with system pressure drops and net temperature glide in a refrigeration and/or air conditioning system. To get started, let’s review a few terms.
Total temperature glide — The total temperature glide of a refrigerant blend is the temperature difference between the saturated vapor temperature and the saturated liquid temperature at a constant pressure.
