Hi folks, I personally use an Engel MT35. It's charged with HFC134a and does a good job as a refrigerator
. This question isn't about the engel - it's about 12V fridges in general.
I know that some of the folks on here are actually HVAC
wizzes and/or have done marine refrigeration
for years. Therefore, it should be noted that R152a is totally safe (as safe as R134a, at least.)
I've used R152a in AC applications with no real problems. In theory, R152a should improve the efficiency of the fridge and reduce the lowest temperature the fridge can achieve.
Has anyone tried R152a refrigerant in their marine
fridges and gotten any improvements?
