Energy and Exergy Analysis of Chest Freezer Using R134a and R290 as Working Fluids Based on Experimental Data [PDF]
Although R134a has a very high global warming (GWP) effect, it is still used as a refrigerant in chest freezers. As an alternative to R134a is R290 which has a very low GWP value, which is only 3.
