WebSince 1 kW = 3412 Btu/h - COP for 1 ton cooling can be calculated as. COP = (12000 Btu/h) / ((1 kW) (3412 Btu/h / kW) = 3.52. A small cooling unit operating at 1 ton per kW (1000 watts) is equivalent to a COP of 3.52 or an EER power of 12. The relationship between EER power and COP can be expressed as. EER power = 12 / 3.52 COP = 3.41 COP WebSep 9, 2024 · By the first law of thermodynamics, the denominator of the expression is Q2 − Q1, and for a reversible Carnot cycle, the entropy in equals the entropy out, so that Q2 / Q1 = T2 / T1. Therefore the coefficient of performance for a Carnot refrigeration cycle can be calculated from (11.8.5) T 1 T 2 − T 1.
