Refigirants with low running cost

[theboss]

Well just figuring our what could be R22 replacements with low running cost.
I know 404 or 507 produces the best capacity but also have high pressure.
Evaporating temps are -5C and sucting return is 0C.

is it a freezer, hvac, chiller, heatpump?
edit: a med cold room? capacity size?

R-407C is good for your data.

Making ice slush for thermal storage..I have a super chilled mechanical screw like a meat grinder...water is pushed from one side and the screw pushes out ice from the other..
