For the normal running pressure in an R134A system, the coil should run at 22 pounds per square inch at the lowest temperature, 45−20 = 25 degrees Fahrenheit. Similarly, at the highest temperature, 60−20 = 40 degrees Fahrenheit, the coil should run at 57 psi. In other words, the normal running pressure of R134A is between 22 and 57 psi in ...

Beenthere does refrigeration a lot and knows the different refrigerants and may know more. R134A is a single compound gas. It can be charged and recovered as either a liquid or vapor the same as R12, R502 (a near azeotropic blend of R22 and R115), and R22 can/could be. To the OP, yes its done fairly often.How to Use a Refrigerant Gauge Set STEP BY STEP to Read Subcooling for R-410A!This is how to Use the Gauge set in order to check an R-410A refrigerant Charge...

What is the vapor pressure of the R-410A? The vapor pressure is 118 PSIG and because it is 85°F outside, the R-410A bottle pressure is 254 PSIG. The pressure in the bottle is much higher than the pressure on the low side of the system so if they are connected, refrigerant will exit the bottle and enter the system. The low side pressure of a typical R410A mini split is between 110-140 psi depending on the operating conditions. Though it can vary, the low side pressure of a mini split should not fall below 100 psi or raise beyond 160 psi. The working pressure of mini splits is depending on factors such as the weather and cooling load. So if it's 85º out the saturation pressure in the system (that's been sitting off) should be 255 psi for 410a. If it's much different than that, then you would want to treat it as contaminated refrigerant when recovering. I assume 5 below would mean 80º in this example to account for the indoor coil being colder, so 236 psi.

Argument #1: Pressure. Tube-side materials in R-410A coils need to be thicker due to the higher operating pressures associated with R-410A relative to R-22. We're not arguing that there's not a difference in operating pressure between the two. There is - roughly 130 PSI for R-410A evaporators compared to about 70 for R-22.

I am an HVAC contractor and am noticing a pattern with several R-410A compressors in (less than one year old) heat pump systems we've installed. After a cold night, I'll get a call from someone saying their outside unit is noisey and system is not heating. What I see when I arrive is the compressor is running, but not pumping as pressures are equalized.The pressure of R-410A is so high that if your hand gets in the way of a leak, it could cut a finger off. This is a myth, as well as a physical impossibility. Devices such as insulin jet injectors require 7,000 to 10,000 psi pressures to puncture the skin and 16,000 to 25,000 psi pressure spikes are normally used. R-410A does exhibit pressures ...Issue with high head pressure on Lennox unit. We are having an issue with a Lennox three ton rooftop unit.
