I have made a refrigeration system at my home. I am using r134a as the refrigerant.
I want to achieve a temperature of about 70-degree Celcius in the condenser part and 0-degree Celcius in the evaporator part. (Currently, I think I am able to achieve 30-degree Celcius in the condenser part and about -10 degree Celcius in the evaporator part.)
In order to achieve so, I was thinking to decrease the length of the condenser coil and increase the evaporator coil length.
Is it possible to achieve such temperature as mentioned above?
