Hello fellow technicians,
I recently relocated to a new state and applied for numerous jobs. Before i apply for this certain job of services and repairing Ice Cream machines and storage units. I read that it required knowledge of working with Ammonia refrigerants. I am curious as to if there is is a difference between CFC refrigerants and Ammonia refrigerants ? Is it the same process when calculating and finding the dew point etc. Or what is the difference between the two when servicing and repairing?
