R410a pressures at 90 degrees.

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. 4.2 MPa is the operating pressure (right on the nameplate). If the pressure you are getting is down 10-15%, you probably need more refrigerant. Consult your user's manual to be sure or call Gree Electric Appliances, Inc. of Zhuhai. Second, you are looking at a heat pump. Verify the system is in cooling mode.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.Sin 90 degrees is equal to one. This degree value can also be expressed in radians as sin(?/2) = 1. This value of the sine function corresponds to one-fourth of the complete arc di...
