What are good pressures 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.
Are 407C pressures compared to R-22?
Devotta et al. (10) informed that R407C had higher pressures than R22 with discharge pressure of R22 being at 2193 kPa for the lower outdoor conditions and 2784 kPa for the higher outdoor conditions. For all operating conditions, the discharge pressure of R-407C is varied in the range 11-13% higher than R22.
What is the saturation pressure for R407C with a temperature of 10 degrees F?
R-407C PT Chart
| Temp (F) | Temp (C) | Vapor Pressure (PSIG) |
|---|---|---|
| 46.4 | 8 | 72.92 |
| 50 | 10 | 78.82 |
| 53.6 | 12 | 85.01 |
| 57.2 | 14 | 91.51 |
What should superheat be on 407C?
Example: The pressure measured at the TEV bulb is 79 psig. 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.
Can you mix R-22 and R407C?
Mixing R22 with R407C According to the 609 EPA rule, mixing refrigerants is illegal and anybody caught doing so will be heavily fined.
Does 407C work as well as R22?
It is found after the careful observation that R22 performs somewhat better than R407C in many aspects i.e. COP, Cooling Capacity, Energy Consumption, and Exergetic Analysis but retrofitting point of view, it is best suitable refrigerant and R410A is suitable for new design.
What should superheat be for 407C?
Do you charge 407C as a liquid or vapor?
liquid
R-407C should always be charged as a liquid. Due to its zeotropic nature, it will fractionate if charged as a vapor, causing poor system performance — and, possibly, system failure. Additionally, the refrigerant supply in the cylinder may become out of spec if discharged as a vapor.
