What is the suction pressure for R407C?
If this is so always evaporating above zero, 4 or 5 deg celcius, R407c will have a low pressure (suction ) of about 50 psi. and a high pressure ( discharge ) of about 280 psi, which is about 55 deg celcius, cooling cycle. Standing pressure ( system not running ) will depend on surrounding temperature of outdoor unit.
What should the pressures be for 407c?

Are 407c and R22 pressures the same?
R407C has 6.60 % more pressure ratio than R22. Lower pressure ratio was suggested for higher compressor efficiency. (11) showed that the average compression ratio of R407C is higher by 3.7% & 5.6% for 1 TR and 2 TR system respectively than that of R22.
What pressure should r410a run at?
For R-410A, a working pressure capability of at least 400 psi is recommended (this includes recovery cylinders). Standard DOT recovery cylinders rated for 350 psi should not be used.
What should superheat be for 407C?
The Pressure/Temperature (P/T) chart shows that the saturated vapor temperature, at the dew point, of R-407C for 79 psig is = 51°F. If the actual refrigerant temperature is 60°F the superheat is 9°F.
What does R134a refrigerant do for your car?
Re-charge your vehicle’s air conditioning system and keep the cold air flowing with R134a refrigerant. This cooling agent ensures that your ride’s AC system is working properly. A telltale sign that your system is not working properly and in need of a recharge is if the system blows hot air while the AC is on.
When was the R-123 refrigerant temperature chart made?
R-123 Refrigerant Pressure Temperature Chart. R-123 refrigerant is most likely a rare find nowadays. It was originally introduced in the 1990’s as a replacement for the now phased out refrigerant known as R-11. You see R-11 contained chlorine. It was found that refrigerants that contain chlorine can actively damage the Ozone layer if they are
Are there any downsides to using R-123 refrigerant?
There were a lot of downsides to R-123 though. One of the biggest was that it was rated as a B1 on ASHRAE’s safety scale. That means that the refrigerant was toxic if breathed in or if you were exposed to it.
How does the R134a high and low side A / C pressure chart work?
R134a Pressure Gauge Chart This chart details how ambient temperature correlates with the system refrigerant charge pressure, and how it affects high and low side psi readings. It can be used for recharging refrigerant, or to diagnose an a/c system based on pressure readings from your gauges.
