On a properly working system, high-side pressure will be about twice the ambient temperature, plus 50 PSI. While charging, an R-134A system is filled with vapor refrigerant until the pressure rises to 30 psig. Similarly, the refrigerant R410A can boil at 0 °Celsius when the pressure is less than 110 psig. 3. Conclusion. In this module, we learned the correct methods of charging a system back with refrigerant.

410a pressure. I installed a 410a, 2 ton condenser and coil today. The low side was 120 with 10 degree super heat, just like the manufacturer recommendations, but the high side was 475psi with 40 degree of subcooling. I felt like 475psi on a 80 degree outdoor temp was really high. Delta T was 14 indoor and the indoor wet bulb was 64degree.

Ferguson HVAC is a national distributor of residential and commercial heating and cooling equipment, parts and supplies. HVAC contractors across the country rely on us for the best unitary and ductless equipment brands and for a wide-range of HVAC products including accessories, controls, air distribution supplies, and … The low side pressure of a typical R410A mini split is between 110-140 psi depending on the operating conditions. Though it can vary, the low side pressure of a mini split should not fall below 100 psi or raise beyond 160 psi. The working pressure of mini splits is depending on factors such as the weather and cooling load. The automotive HVAC gauge readings should be between 35-40 PSI on the low side and 145-160 on the high side, assuming an ambient temperature of 70 degrees Fahrenheit. ACLAB Note: The respective gauges should have a pressure temperature chart to align the ambient temperature with the proper pressure.
