What is the suction pressure of R404A?
R404a Refrigerant Pressure Chart
| Temperature (Fahrenheit) | Temperature (Celsius) | R404a Pressure |
|---|---|---|
| – 40°F | – 40°C | 4.3 psi |
| – 35°F | – 37.2°C | 6.8 psi |
| – 30°F | – 34.4°C | 9.6 psi |

How does a PT chart work?
PT charts for the zeotropic blends list two columns next to each temperature: one for the saturated liquid (bubble point) and the other for the saturated vapor (dew point). For these blends, the vapor and liquid pressures are only separated by 1 or 2 psi.
What are normal pressures for 407c?

What should my pressures BE for 407c?
Re: R407c Pressures 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.
What should the gauges read on R22?
R22 gauge pressure is 10.9 bar or 158.2 psi. High side pressure typically varies by equipment and metering controls. Low pressure or suction side typically varies by equipment. Low-pressure refrigerant turns on the carrier HVACR at 50 psi (R22 pressure at 30 degrees) and closes at 100 psi (R22 pressure at 85 degrees).
What temp is R22?

Can R407C replace R22?
The best replacement for R-22 Freon is usually R-407c. It has a very low loss in capacity (0 – 5%) relative to R-22 and is less expensive than many other R-22 replacement refrigerants. If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R22.
What should my AC pressures be for R410A refrigerant?
Suction pressure of an Air-Conditioner with R410A Refrigerants typically ranges between 115 Psig to 125 Psig when operated at an ambient temperature of 35 degC. The discharge pressure at this operating conditions hovers around 400 Psig.
What is high pressure refrigerant?
High-pressure appliance means an appliance that uses a refrigerant with a liquid phase saturation pressure between 170 psia and 355 psia at 104 °F. Examples include but are not limited to appliances using R-22, R-407A, R-407C, R-410A, and R-502.
What is refrigerant temperature?
A refrigerator maintains a temperature a few degrees above the freezing point of water. Optimum temperature range for perishable food storage is 3 to 5 °C (37 to 41 °F). A similar device that maintains a temperature below the freezing point of water is called a freezer.
