In this article we will discuss an HVAC units refrigerant pressure on both the high side and the low-pressure side while the system runs. It is important to know the range of these pressures in order to understand why and how charging and recovery are performed.
In early January of this year I had an installer put in a new Amana dual fuel heat pump system. 3 months later the compressor stopped running low pressure cutoff and the company put in 1 pound of 410a refrigerant. They did not leak test.
4 months later the unit did the same thing again. Not really trusting this installer I got another company to spend several hours leak testing and. High Pressure Switches Part PS-450-500 Features.

Press ctrl F to find model number below if you have any questions call 734-326-3900 for further information. OPERATING PRESSURE POINTS Systems using R-410A operate at higher pressures than R-22 points out the Field Diagnostics team. For example to produce an evaporating temperature of 40 degrees F and a condensing temperature of 115 degrees the suction and head pressures would be 83 psia and 257 psia in an R-22 system while they would be 133 and 406 psia respectively in an R-410A.

A KP pressure switch can be connected directly to a single-phase AC motor of up to approx. 2 kW or installed in the control circuit of DC motors and large AC motors. KP pressure switches are fltted with a single-pole double-throw SPDT switch.
The position of the switch is determined by the pressure switch setting and the pressure at the. Typical low pressure or suction side pressure for R410A is about 120 psi varying by ambient temperature here assuming 75F may vary by equipment and metering controls. Typical high side pressure for R410A is 600 psi at an ambient outdoor temperature of 95 F may vary by equipment.
