Coefficient of Performance (COP) of a Heat Pump: What Is It?

The coefficient of performance, or COP, of a heat pump is an indicator of the unit's energy efficiency. It expresses the ratio of the thermal energy produced to the electrical energy consumed during operation.

A high COP indicates that the heat pump uses less electricity to produce more heat, making it more efficient and sustainable.

Heat pump COP: what it is and how it works

COP varies depending on the heat pump technology and the environmental conditions under which it operates. For example, air-to-water heat pumps might have a higher COP under moderate than extreme weather conditions.

This parameter is critical in assessing the efficiency of a heat pump, especially in heavy-use settings such as domestic or industrial heating.

Optimal values of the heat pump coefficient of performance

Calculating the COP of a heat pump helps to understand how cost-effective and eco-friendly it actually can be. A typical COP value for heat pumps used for heating can range from 3 to 5, meaning that for each unit of electricity used, the heat pump can produce 3 to 5 units of heat.

Going into more detail, COP values for heat pumps vary depending on the type of system:

• For air-to-air heat pumps, COP values generally move between 3 and 4.
• For air-to-water heat pumps, the COP should be at least 4, based on an air temperature of 2°C and a water temperature of 35°C.
• For water-to-water heat pumps, an ideal COP is around 5.5, based on a groundwater temperature of 10°C and a heat transfer water temperature of 35°C

Importance of COP for cost and environmental impact

A high COP not only reduces the operating cost of the heat pump but also contributes to the reduction of environmental impact by decreasing CO2 emissions due to the use of electricity.

For users, this translates into lower energy bills and a lower ecological burden.

Choosing a heat pump based on COP

When choosing a new heat pump, it is essential to consider COP as a deciding factor.

Heat pumps with a higher COP may have a higher initial cost, but the long-term benefits can amply justify the initial investment.

In conclusion, the COP of a heat pump is a parameter that should not be overlooked when selecting these devices. Choosing a device with a high COP means ensuring greater energy efficiency and contributing to environmental sustainability.
