I understand the method but what is taking place on the inside of the system? And what does it mean when we have to low temp in sucooling and superheat do we add refrigerant or take it out??

[DrZarkloff]

@doughgetta2 Typically, if you have a low super heat or subcooling it means that you have an over charge.

You can start by learning how to spell and type in English. lol

@dossen2620 You'll need a P/T chart especially when you're using refrigerants that aren't listed on the gauges.

Surely u can make a better quality video. Its painfull to watch

@dossen2620 You need more than just pressure, you also need line temp to frigure out the subcooling and super heat. You then use the subcooling and/or superheat levels to helpt determine whats going on with the system. There are many things that low superheat or high/low subcooling could be, thats why techs get training.

I know the superheat and subcooling is different with different types of metering devices, but what is the perfect superheat and subcooling for a TXV?
