Worked example

Inputs

Hot reservoir temperature: 320 K
Cold reservoir temperature: 280 K
Heat delivered to hot reservoir: 10000 W

Expected results

Reversible heating COP: 8
Reversible cooling COP: 7
Minimum reversible work: 1250 W

How to use this tool

Enter every input in the labeled units; use measured or independently specified properties.
Check the stated model assumptions before calculating.
Interpret the output as a model estimate and verify it independently for the intended application.

Try this example

{
  "hot": 320,
  "cold": 280,
  "heat": 10000
}

Accuracy and scope

Ideal reversible reservoirs; actual heat-pump COP is lower and depends on equipment and temperature approach. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
