COP for Heating: –
COP for Cooling: –
The Coefficient of Performance (COP) Calculator measures the efficiency of heating or cooling systems by determining the ratio of heat energy output to the energy input. It is a critical metric for evaluating systems like heat pumps, refrigerators, and air conditioners. A higher COP indicates a more efficient system, which helps in reducing energy costs and improving environmental sustainability.
This tool is particularly useful for engineers, technicians, and facility managers aiming to optimize HVAC systems or analyze the performance of energy-efficient technologies.
Formula of COP (Coefficient of Performance) Calculator
For Heating:
COP = Temperature of Heat Supplied / (Temperature of Heat Supplied - Temperature of Heat Source)
For Cooling:
COP = Temperature of Heat Removed / (Temperature of Heat Source - Temperature of Heat Removed)
Detailed Formula Components:
- Temperature of Heat Supplied: The absolute temperature at which heat is delivered, measured in Kelvin or Rankine.
- Temperature of Heat Removed: The absolute temperature at which heat is absorbed, measured in Kelvin or Rankine.
- Temperature of Heat Source: The absolute temperature of the heat source or sink, measured in Kelvin or Rankine.
- COP: A dimensionless value representing the efficiency of the system.
Important Notes:
- Use absolute temperature units (Kelvin or Rankine) for accurate results.
- Higher COP values indicate greater efficiency.

Example of COP (Coefficient of Performance) Calculator
Scenario:
Calculate the COP for a heat pump delivering heat at 320 Kelvin while drawing heat from a source at 290 Kelvin.
Step-by-Step Solution:
- Identify the Formula: Use the heating formula:
COP = Temperature of Heat Supplied / (Temperature of Heat Supplied - Temperature of Heat Source) - Substitute Values: COP = 320 / (320 - 290)
- Perform the Calculation: COP = 320 / 30
COP = 10.67
Result:
The COP for the heat pump is 10.67, indicating efficient performance.
Most Common FAQs
The COP measures how efficiently a system converts energy input into useful heating or cooling, helping optimize energy consumption and reduce costs.
Yes, for systems like heat pumps and refrigerators, the COP is typically greater than 1, indicating that the system delivers more energy than it consumes.
Regular maintenance, upgrading to modern equipment, and optimizing operating conditions like temperature and load can significantly improve COP.
