Any deviation from this range might compromise the cooling efficiency, leaving certain areas less cooled than others. 2.

May 5, 2016 · 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. A R-410A evaporator running below 100 psig will freeze-up just like its R-22 cousin. One of the most common causes of low suction pressure is loss of critical refrigerant charge caused by small leaks over time.

Theoretical calculations reveal that at the above high-temperature cooling conditions, a 2-psi suction pressure drop produces about 2% loss of efficiency and 2.4% loss of capacity in an R-22 system. But in an R-410A system, the suction pressure drop can be allowed to go as high as 3.1 psi before the same losses in performance are seen.
