The R410A is a clear winner in terms of pressure applied in the Air conditioner. Viewed 1k times 0. If you use R-22 in the same system as R-410a, the compressor is going to be trying to work two different fluids through the same coils as both refrigerants respond differently to different mechanical situations. The heater is standard natural gas and I had it going since last fall and it served me well for the winter. Additional pressure drop may be tolerated in certain applications. R-410A, or Puron, is one of the most popular refrigerants in today's modern world. Systems designed for R410A can take advantage of its ability to use smaller components, making it a key refrigerant for domestic and light air conditioning equipment. Because R-410A has higher pressure, it requires a different manifold pressure gauge than what is typically used with R-22. The pressures used for brazing are usually 5 to 7#. The gauge will have a pressure reading in pounds per square inch gauge (PSIG) and a R-410 refrigerant saturation temperature measured in degrees Fahrenheit (F).
