    large refrigeration plant cooling tower issue



    Hi sirs
    Large refrigeration usually use cooling tower for condensing. What issue should be considered if use evaporative condenser instead of cooling tower? Is the refrigerant side large pressure loss the main factor ?
    welcome input!

    regards

    Dear LC SHI
    By using evaporative condensors u can have a better efficiency and decrease power consumption but the main problem with this system is water hardness. Because scales tends to stick to metalic surfaces more than wooden or polymer materials so it affects directly on heat transfer flux.
    By the way I have experienced evaporative systems and I prefer this systems to cooling towers or even air cooled condensers in large refrigerations

    Hi Pirestani

    If adding the water softening appliance,how about it to cooling tower?

    In evap condenser systems, refrigerant is piped directly through condenser sprays.

    In cooling tower, you need a condenser water circuit.
    Cooling tower can be far from the condenser.
    Can be matched to packaged chiller.
    No refrigerant piping to do.

    Evap condenser needs to be located closer to the compressor.
    Gives lower head pressure therefore higher system COP.

    Cooling Tower system

    Water pipe network
    Condenser pump
    Shell and tube condenser
    water needs treatment
    de-scaling on S&T

    Evap cooler system
    Evap condenser
    Refrigerant piping
    water treatment


    It would be good to get a response from guys like BAC and Evapco for this question.

    hi shi.
    if u have possibility of water treatment properly, and the distant between ur package and its condenser is not so long, the initial and maintenance costs will be decrease sufficeintly by using evaporating condenser.also the occupied space is smaller than cooling tower or air cooled condenser.
    pay enough attention to water leakage.
