The tables contained on this page list approved refrigerant numbers from Standard 34, which describes a shorthand way of naming refrigerants and assigns safety classifications based on toxicity and flammability data.What does the GWP value mean? GWP stands for “global warming potential”, which is the potential for a substance to contribute to climate change.The GWP value of a refrigerant defines its global warming potential relative to CO₂ (also known as CO₂ equivalent).The value describes the global warming effect over a certain period of time, which for …system using R422D as the refrigerant when the gauge pressure at the evaporator outlet reads 48 psig. -Find ~48 psig in Bubble Column: 20°F -Find ~48 psig in Dew Column: 27°F -The Average Coil Temp = (27+20)/2 = 23.5°F A more accurate estimate would account for inlet quality.
