What is r416a refrigerant?
A blend of R134a and R124. Used for medium temperature refrigeration or for automotive as a drop in refrigerant. Includes R124, an HCFC compound and is on the EPA phaseout schedule to cease production as of 12/31/2019.
What is the correct pressure for r12 at 40 degrees?
High Pressure
| °C | °F | R-12 |
|---|---|---|
| 4.4 | 40 | 37.0 |
| 7.2 | 45 | 41.7 |

| 12.8 | 55 | 52.0 |
What is a pressure temperature chart?
The pressure-temperature (PT) chart is a valuable tool that service technicians use to check proper system operation. Traditional PT charts list the saturated refrigerant pressure, in psig, with a column for temperature down the left side.
What replaced Hot Shot 2?
An R-12 Refrigerant Replacement R-401A. R-401B. R-409A. R-414A.
What pressure should R12 run at?
Registered. R12 should run about 30-35 psi suction for auto AC. R134a is practically the same, but slightly lower – it has a very similar pressure/temperature relationship to R12, especially on the low side.
What are good pressures for 410A?
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 are normal operating pressures for 410A?
A normally operating R-410A system with the same condensation temperature of 120 degrees and a 45 degree evaporator saturation temperature will have a high side pressure of 418 psig and a low side pressure of 130 psig.
When will R-410A be phased out?
The HVACR industry is on the cusp of yet another refrigerant phasedown. R-410A is scheduled for elimination from all new systems in 2023. Many HVACR contractors are not prepared for the change, and there are many questions.
What is suction and discharge pressure of R410a?
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. The discharge pressure at this operating conditions hovers around 400 Psig.
How to calculate superheat and subcooling 410A?
Superheat and Subcooling Charging Methods . Cylinders R-410A condensers are factory charged for 15 feet of line set. To calculate the amount of extra refrigerant (in ounces) needed for a line set over 15 feet, multiply the additional length of line set by 0.6 ounces. Note for the
What is a 410 refrigerant?
R410A also called Puron, or Forane 410A is a rose-colored, no flammable HFC refrigerant gas for HVAC units and refrigeration compressors. It is an ideal substitution for R22 refrigerant gas. HFC-410A is a hybrid of refrigerant gas consisting of 50% R32 and 50% R125 but not any chlorine.
