The low-pressure side, when connected to the gauge, should read less than 100 psi. PSI is the common measurement for pressure used in terms of pounds per square inch. By the time the refrigerant reaches these lines it has lost most of its heat and has collapsed into a liquid state, taking up less volume. This leads to a low-pressure environment ...ACHR NEWS: In terms of properties and performance, how does R-454B compare to R-410A (e.g., efficiency, capacity, pressures, discharge temperatures)?
