Ac Gas Pressure Chart

The pressure for an ordinarily operating R134a is between 22 and 57 pounds per square inch PSI. For a general reference you can check out this chart of R-134a system pressures.

For a 15 tonne AC the refrigerant gas pressure needs to be somewhere between 6070 psi anything less than 60 psi the refrigerant gas has to be filled 5 psi is no harm.

On the high side R-134a pressures usually run 22 to 25 times the ambient temperature entering the condenser.

On an R-134a system. AC PRO is the easy DIY car AC repair that saves time money. 52 rows AC Refrigerant Pressure Chart Pressures shown in the charts are provided as a general.

So if the ambient temperature is 80F youll see high side pressures running between 176-psi and 200-psi. Remember there are two sides to the chart. This chart details how ambient temperature correlates with the system refrigerant charge pressure and how it affects high and low side psi readings.

During air conditioning mode the pressure on the vapor line of an R-410A system will be somewhere between 102 to 145 PSIG. If the system had R-22 the vapor pressure would be between 58 to 85 PSIG but these pressures will be dependent on the wet bulb temperature inside the building and the ambient temperature outside the building. The highlighted screw needs to be removed and gas has to be filled through it by checking the pressure.

If you find youve got a low pressure on the low side of your system then its most likely that youve got a leak as that is a common problem in automobile air conditioning. The warmer it is outside the higher the pressure will be. This simple fix recharges the R-134a freon stop leaks gets your car AC cold again.

Furthermore R134A is a chemical refrigerant in automotive and domestic use air conditioners. It can be used for recharging refrigerant or to diagnose an ac system based on pressure readings from your gauges. So weve put together as much information as we can get to create Filling Charts for every manufacturer and model which we can think of.

R410A Pressure Temperature Chart 14 1223 1122 16263 1219 1118 16205 16 1295 1193 17303 1291 1189 17243 18 1370 1268 18389 1365 1264 18325. Therefore in a normal R134a the low-pressure side is 90 degrees or less and the PSI should be close to 30. Air conditioning service manuals and training refer to.

We have the low and the high. R134a Pressure Gauge Chart. Additionally HVAC Systems such as chilled water systems in both commercial markets and industrial markets.

Low-side air conditioner compressor motor pressure. R-134A Refrigerant Pressure Temperature Chart - R-134A is an inert gas also known as Tetrafluoroethane and for air conditioner systems. The refrigerant entering the condenser will be around 130F.

Agent frigorific R134a tabel. This is the pressure in the air conditioners refrigerant suction line low side pressure during compressor operation and this will be a relatively low number often less than 100 psi. Weve all been there you go to do a re-gas on a customers car and theres no sign of the label telling you how much refrigerant it needs.

Pressures can vary from car to car based on the system and the pressure in your system will also vary with the ambient temperature.
