    KW refrigeration div by KW electric input to motor.
    You need a Kw meter really. Electric KW= KVA x Pf (power factor)

    that formula is for chiller COP. If you are doing total plant COP, then you need alll pumps and tower fans. Tower fans are cycling so you would need a KWmeter to measure that. BUT CHILLER cop will vary depending on how much load is on chiller ie. 25% Cop is different from 100% COP.
    Not sure what you are really looking for.
