Which refrigerant R$-134$a or R$-410$a and why $($show your calculations$)$ would you use if you cool industrial process requiring $-10$C $($temperature in evaporator$)$ while temperature in condenser$$s outlet will be $30$C$.$ Use data from tables. Enthalpy read from the table for a superheated vapor after compressor is $420\mathrm{.}5$ kJ$/$kgK and $308\mathrm{.}8$ for R$-134$a and R$-410$a respectively.
