What is Refrigerant Line Sizing Guidelines about?
This document provides guidelines for sizing liquid and suction refrigerant lines for air conditioning and refrigeration systems. Key points include: - Liquid line velocity should be between 100-400 fpm, pressure drop no more than 35 psi for R-22 or 60 psi for R-410A. - Suction line velocity should be between 1000-3000 fpm, pressure drop no more than 3 psi for R-22 or 5 psi for R-410A. - Long line sets over 75 feet must include additional components like a crankcase heater to prevent oil migration issues.
