Math & Numbers
COP Calculator (Coefficient of Performance, COP = Q_c / W)
Compute the Coefficient of Performance (COP) of a chiller / heat pump: COP = Q_c / W, where Q_c is the cooling capacity and W the work input (both in consistent power units; COP is dimensionless). Three modes: solve COP (given Q_c and W), solve cooling capacity (given COP and W), or solve input power (given COP and Q_c). Capacity in W/kW/BTU·h⁻¹/ton/kcal·h⁻¹, power in W/kW/hp; all converted to W internally.
Quick start
Call this tool from your code in three languages.
curl -X POST 'https://api.elysiatools.com/en/api/tools/cop-calculator' \
-H 'Content-Type: application/json' \
-d '{"mode":"cop","coolingCapacity":3500,"capacityUnit":"W","inputPower":1000,"powerUnit":"W","cop":0,"decimalPlaces":4}'API reference
Send a POST request with your inputs as JSON. File parameters require a separate upload first.
