    Re: Digital scroll chiller

    Dear colleague ,

    Because of the symptoms presented by its control system with Copeland Compressor "Digital" and electronic expansion valve indicating that the valve closes after showing little superheat the possible causes are the following
    1 - The Evaporator is short because the commercial chillers are for air conditioning applications and / or the flow is low . . . Solution : select an evaporator for the operating conditions
    2- That you are using a liquid solenoid valve together with the electronic expansion valve . . . Solution : remove the solenoid valve

    Best regard
