Refrigerant pressures
Hi all I am just posting to ask if there are any refrigerant pressure charts out there that will tell me what pressure a certain gas should be running at for eg a cold room on 134a.. I know from going of my pt chart 0 deg is 28psi but im just not sure on what the head pressure should be runnning at? and I know all systems will be different but is there a rough guide to go off? any help would be good thanks

Re: Refrigerant pressures
use the rule of thumb whatever the condenser air on is the temp/pressure of the refrigerant should be 10k higher
I can fix broke but I cant fix stupid :)
