Re: H/p L/P switch settings
Refrigeration is about temperatures, not pressures. When you learn to think in terms of temperatures, you can work with any refrigerant. A new refrigerant only requires a new P/T chart.
Back when only a few refrigerants were in common use, I told people to paint over the pressure scales on their gauges, so they would be forced to use the temperature scales. Temperature is what really matters.[/QUOTE]
temperature alone is as irrelevant as pressure in isolation. it seems slightly patronising - to me at least- when some say
' forget the pressure tell me the temperature'
it's nonsense you cannot diagnose by temperature alone..
if i said the suction pipe is 12 deg's c what's wrong?
could you tell me??????
i rather doubt it..
no you would give me a list of alternatives much the same if i said 'the pressures 34psig whats the matter?'
rant over back to the wine..;-))
cheers
