They include two hydrofluorocarbons, R-125, R-134A, and one hydrocarbon, R600A. The refrigerant comes with a variety of features, benefits, and applications. One of the most notable functions is that 422B is a drop-in replacement for R22.R407c is an HFC refrigerant that will replace the R22 refrigerant, as per Montreal Protocol. It is a mixture of R32 (23%), R125 (25%), and R134a (52%) that has a boiling point of -46.84°F. The same as R22, due to useful pressure-temperature properties, R407c is used in air conditioning systems, cars, and refrigeration units. Below, you will ... sioux falls sd jail roster Suction Pressure/EVAP DTD Rule of Thumb Another common old-school rule of thumb is that suction pressure should be close to the outdoor temperature in an R22 system. However, this rule of thumb (obviously) does not work on an R-410A system. A more applicable guideline is 20°-25° suction saturation below outdoor ambient.The following properties are included: density, pressure, internal energy, enthalpy, entropy, heat capacity at constant pressure, heat capacity at constant volume, speed of sound, and the Joule-Thomson coefficient, in both single-phase states and along the liquid-vapour saturation boundary.
