WebWith a global warming potential (GWP) of 148, the non-ozone depleting, hydrofluoroolefin (HFO) based Opteon™ XL20 (R-454C) refrigerant offers similar performance to the refrigerants—like R-404A and R-22—it was designed to replace. Opteon™ XL20 allows much higher charge sizes than other highly flammable refrigerants.
The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs. The COP usually exceeds 1, especially in heat pumps, because, instead of just converting wor… sawyer lutheran churchWebJan 1, 2024 · Nakaqawa et al.
