    chiller cooling capacity



    hey guy, i m confuse with this.... hopefully can get some explanation...

    - system cooling capacity KW
    - compressor capacity KW
    - expansion valve kw?

    for example if chiller capacity 100KW, what is the relation between compressor, condenser, expansion valve, and evaporator....

    can share some formula & calculation for this?
    thanks...

    Re: chiller cooling capacity

    100 kW cooling, +/- 3 COP = 33 kW compressor capacity or 25 kW at a COP of 4
    COP is a factor of the working conditions (LP versus HP)
    Expansion valve is 100 kW at a certain evaporation capacity and a certain subcool and a DP over the valve

    There are no formulas nor calculations for this, only manuals/selection tables of the different manufacturers.

    Yes and no, you only can make a rough guess because the expansion system can regulate its capacity within a certain margin.
