What is the GWP of ammonia?
Ammonia is safe for the environment, with an Ozone Depletion Potential (ODP) rating of 0 and a Global Warming Potential (GWP) rating of 0. Ammonia is substantially less expensive than CFCs or HCFCs.
Is r410a a HFC refrigerant?
R-410A is a member of the hydrofluorocarbon (HFC) class of refrigerants and is composed of equal parts R-32 and R-125. … The table below shows some other properties of R-410A. Applications. R-410A is primarily used in commercial and residential HVAC systems.
What is a Class 1 or Class 2 refrigerant?
Class I includes the fully halogenated CFCs, halons, and the ODSs that are the most threatening to the ozone layer. Class II compounds are those substances that are known or reasonably anticipated to have harmful effects on the stratospheric ozone layer. Class II substances are hydrochlorofluorocarbons (HCFC).
What is R125 refrigerant?
R125 is used to make a variety of comfort and commercial refrigeration refrigerants. … R125 (HFC-125) is a fluorocarbon essential in generating new refrigerants for the non-ozone-depleting HFC refrigerants R410A, 402A, 402B, 404A, 407A, 407C, 408A, and 507.
