It’s called a CoP, Coefficient of Performance. It essentially is a factor of how much electricity you put in and how much cooling power comes out.

Cooling towers can have a CoP of 12 and beyond, whereas compression cooling usually lingers at around 3 to 3.5. so at a CoP of 3 for instance, you could put in 1 kW of electricity and get 3 kW of cooling power.
