The internal pressure relief for R-410A will open at 550-625 psig. Last year a new combatant entered the fray when Japanese company Asahi Glass announced that it, too, would be producing an R410A replacement. States of refrigerants are classified in the following 3 categories: The difference between discharge pipe temperature and condensing temperature is called the Discharging Superheated Degree (DSH). 2°F WB entering air temperature. 1 Refrig charge (HFC-410A) - ckt 2 (lb) 5. k = Ratio gas specific heats, c p /c v. 5 As a result, manufacturers of heat pump and air conditioning equipment redesigned their systems to accommodate R-410A, a chlorine-free refrigerant compared to R-22.
