What do the SCOP and SEER values mean?
The SEER (seasonal energy efficiency ratio) and SCOP (seasonal coefficient of performance) indicate the energy efficiency when the system is operated throughout the entire year.
For air conditioning systems and heat pumps, the average coefficient of performance over one year is called SEER in cooling mode and SCOP in heating mode. Temperature fluctuations over the course of the year are taken into account. The higher the SEER value, the more efficient the unit is.
The higher the SEER value, the more efficient the unit is and the lower the operating costs as a result.
What do SEER and SCOP mean: Energy efficiency standards
Year-round efficiency under the microscope: SEER and SCOP
The energy efficiency of air conditioning systems and heat pumps is assessed by the SEER and SCOP values. These performance indicators stand for "seasonal energy efficiency ratio" and "seasonal coefficient of performance" and represent efficiency over the entire year. They provide more information compared to the older values EER and COP (which only apply to cooling and heating operation), as they take seasonal fluctuations and additional energy consumption into account.
Realistic assessment thanks to average temperatures
The SEER and SCOP values are calculated based on the average temperature over the year. Various temperature conditions are taken into account in order to ensure a realistic efficiency assessment.
Advantages of inverter technology
The advantages of inverter technology become clear by incorporating part load operation into the efficiency calculation. This technology dynamically adapts the unit output to what is actually needed and is therefore more energy-efficient than conventional systems.
Complete recording of energy demand
Besides the actual operating power, the SEER and SCOP values also take auxiliary energy consumption into account. This includes energy consumption in standby mode and when defrosting, something which means a comprehensive evaluation of the energy needed.
What do the figures mean?
A SEER value of 6.0 means that 6 kW of cooling capacity is achieved on average per 1 kW of power consumption across the year. Similarly, a SCOP value of 4.12 shows that 4.12 kW of heating capacity on average is produced per 1 kW of power consumption over the whole year. These figures illustrate the efficiency and cost-effectiveness of the units over the course of the year.
