    pressure temperature chart



    Hey,

    I am a apprentice fridge engineer and am getting on rather well.
    I believed that I knew how to work out pressures and temperatures using pressure temperature charts but after a chat with my friend I am hugely mind boggled.

    Could someone please explain to me in the simplest form about how to calculate pressures for systems, both AC and fridge.

    I'm not 100% sure how to use the charts to figure out if a system is Short of gas or what the room temperature will be at x PSI and things like that.


    Much appreciated for the responses

    A good source of useful information, apart from here, is the Sporlan website.

    To start with download document 10-35 from here...

    Also look up system balance, and Gary's post in fundamentals
    101.
    compare saturated suction to room temp, if more than 10deg c (approx) something wrong.
    Also discharge saturated pressure compared to ambient.
