    Re: question

    I'd go for C i know im probably wrong but.... well at least i tried


    Edit just been thinking about it and Bulb Pressure should be equal to Refrigerant Pressure + spring Superheat so i would now say the answer is D.
    In a TXV, the forces need to be balanced for it to be stable.

    It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

    Re: question

    Im still saying D
    Evaporator Pressure + Spring Pressure = bulb pressure
