EER - Energy Efficiency Ratio of refrigeration systems

The EER Energy Efficiency Ratio

describes the relationship between power consumption and discharged cooling capacity. It is determined under the following measuring conditions: 35 °C outside air temperature / 27 °C inside air temperature. Thus, the EER is determined analogously to the COP value.

EER = QK / PEL
