kW per Ton Calculator (Chiller Efficiency)
Chiller plant efficiency from measured load and power — the operator's daily KPI.
Include pumps and towers for the honest 'plant' number — a 0.55 chiller in a badly pumped plant can be a 0.9 system.
Formula
kW per Ton Calculator (Chiller Efficiency) is a free kw per ton for HVAC designers, technicians and energy auditors — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About kW per Ton Calculator (Chiller Efficiency)
Chiller plant efficiency from measured load and power — the operator's daily KPI. The calculation implements kW/ton = P/Q; COP = 3.517/(kW/ton) (ASHRAE 90.1; AHRI 550/590). Include pumps and towers for the honest 'plant' number — a 0.55 chiller in a badly pumped plant can be a 0.9 system.
