R22 low side pressure at 70 degrees.

The SC might be normal , but the normal head for a r410 system w/ a 68* ambient should be closer to 300psi and the normal suction press should be closer to 110psi w/70* IDB. Those p/t's sound more like r22. kdean1, buttwheat liked this post. As others have said it sounds like a TXV and maybe low on juice.If the air conditioning isn’t blowing cold air and the low side pressure is too high, it could be caused by issues with the condenser fan. However, there’s also the possibility that the system has been overcharged with too much refrigerant. 1. Defective Condenser Fan. When the fan becomes damaged, airflow through the condenser is diminished.In the example of an R-410A packaged unit with a surrounding air temperature of 70°F, the pressure on both the high and low-pressure side of the system will be 201 PSIG. If a new R-410A refrigerant bottle had a surrounding air temperature of 70°F, the pressure inside the bottle would be 201 PSIG.At 70 degrees F, I'm measuring 30-32 psi on the low side and 250 psi on the high side. When the radiator fan kicks in from low to high speed, the high side pressure drops to about 225 psi. No idea what triggers the fan speed. I found a AC pressure chart online that said at this temperature, my low should be around 35psi and high at 150psi.Critical Pressure..... 4990 kPa Critical Density.....523.8 kg/m3 Critical Volume 3..... 0.0019 m /kg Units and Factors P = Pressure in kPa.

R-410A has a GWP of over two-thousand whereas R-32 has a GWP of only six-hundred and seventy-five. While R-32 isn’t perfect it is a lot better then R-410A. That is why we are beginning to see a rise of usage of R-32 in the European Union and here in the United …The perfect refrigerant reading depends on several factors, like atmospheric pressure and temperature. I like to see an average range of 58-85 PSI on the low side and 120-300 PSI on the high side. These indicate that the unit is running okay and should be cooling properly.
