HVAC&R EFFICIENCY TOOL

EER / COP / kW per TR Converter

Convert common steady-state HVAC&R efficiency metrics without intermediate rounding.

EQUIVALENT EFFICIENCYCOP 3
EER: 10.236 Btu/WhkW/TR: 1.1723

These are steady-state metric conversions only. They do not calculate seasonal efficiency, IPLV/NPLV, part-load performance, compressor-only efficiency, or equipment rating compliance.

Engineering Method & Assumptions

EER (Btu/Wh) = COP × 3.412141633. kW/TR = 3.5168528420667 ÷ COP. Conversions use International Table BTU and the toolbox refrigeration-ton definition without intermediate rounding.

Scope

This is a metric conversion utility. It does not calculate seasonal or part-load ratings such as IPLV/NPLV and does not determine equipment compliance.
