    temp out of control



    what can cause a system which has suction 26PSI discharge 195 psi and 28F at the end of tvx to go to > 60 F when you add refrigerant to it that give suction 44 psi and discharge 225 psi

    Your question doesn't make any sense. Try again.

    Who gives you this "academic" questions.
    Maybe, if you present them in original form, you end up with right answers much faster.

    Re: temp out of control

    This is a kind of chiller (pool) but water is not flow out.
    Without load on it we find
    Liquid line 96 F
    Suction line 65 F
    Condenser 89.6 F
    Climate 93.2 F

    Saturated Suction 5.2 F
    Saturated condensing 101 F

    Re: temp out of control

    Cond air in temp?
    Cond air out temp?

    What is "condenser" and "climate"?
    What you mean by "but water is not flow out"?
    If "climate" is ambient air temperature and "condenser" is condenser air out temperature, than that numbers doesn't make sense!
    What you mean "without load"?

    gas r22

    water chiler

    climate temp is the temp arount the system

    condenser temp is the temp i found on the oposite face of the conderser blower

    Describe evaporator!

    Why I have feeling like I am pulling informations you hesitate to give?
    Or it is language barrier?

    Saturated Suction 5.2 F
    Saturated condensing 101 F
    101F minus 96F = 5F subcooling.

    Add refrigerant until the subcooling is 15F.

    Then take all of these measurements again... with load.

    Sorry, aspiration condenser is something I never heard or saw.

    How you move water around evaporator, or it moves naturally?

    Re: temp out of control

    have you got load on the cooler?
    i assume that you have a good water flow.
