Hi all, once again i've been reading some books and im confused by the whole different temperatures. I always measure superheat in DegC but i've read and seen many posts stating for example on one on one particular system that superheat should be 20DegF, which equates to -7DegC. I though superheat should be around the 5-10DegC mark which equates to 41-50DegF. Am i missing something. Also i see posts from people using K. Now i know that K is kelvin and what it is but i dont understand how they convert the degf to kelvin?
For example i shall post a line from a book that i am reading;
If the difference between the 2 temperatures is more than 30degF (16degK) dt, the condensor is not getting enough airflow.
