Process refrigeration COP calculator

Convert cooling output to the same energy-rate units as electrical input before forming the ratio.

Units
COP=12,000×Qton3412×P\mathrm{COP} = \frac{12{,}000 \times Q_{\text{ton}}}{3412 \times P}

Worked example

Given

  • QtonQ_{\text{ton}} = 150 ton
  • PP = 120 kW
COP=12,000×1503412×120≈4.396\mathrm{COP} = \frac{12{,}000 \times 150}{3412 \times 120} \approx 4.396
