Ive been learning up on SH & SC and it seems there are a 100 different answers and opinions on it. But that seems to be the norm about everything.
Question is why does a A/C or H/P use SC on TXV systems and SH on orfices/pistons? And then why does a Refrigeration unit if it has a valve require SH method? Does elp SC method work on heat pumps in heating mode?
Thanks for your help guys
