Introduction
Heat pumps, air conditioners and liquid chilling packages can be selected and compared at standard
rating conditions. These conditions do not represent the usual operating conditions of the equipment
over a season. Better comparison for equipment can be assessed by determining Seasonal Energy
Efficiency Ratio, Seasonal Coefficient of Performance and Seasonal Energy Performance Ratio that enable
to take into account more representative operating conditions and performance for several part loads.
Fixed capacity heat pumps, air conditioners and liquid chilling packages deal with varying loads by
varying the operation time. The efficiency of the system is dependent on the effectiveness of the
controlling thermostats. Variable capacity air conditioners, liquid chilling packages and heat pumps, by
continuous or step control of the compressor, can more closely match the varying load improving system
efficiency.
This document also applies to hybrid units as defined in this standard.
This document provides part load conditions and calculation methods for calculating the Seasonal Energy
Efficiency Ratio (SEER ), the seasonal energy performance ratio (SEPR) and Seasonal Coefficient of
on
Performance (SCOP and SCOP ) of such units when they are used to fulfil the cooling and heating
on net
demands.
This document provides methods for calculating the seasonal space cooling energy efficiency η and
s,c
seasonal space heating energy efficiency η .
s,h
Other electric energy consumptions can occur when the unit is not used to fulfil the cooling and heating
demands such as those from a crankcase heater or when the unit is on standby. These consumptions are
considered in the calculation methods for SEER and SCOP.
This document also considers Seasonal Energy Performance Ratio of process chillers (SEPR) which is
representative of variations in loads throughout a complete year. Test conditions and test method are
described to calculate this SEPR.
SEER/SEER , SCOP/SCOP , SCOP and SEPR calculations are based on calculated or measured values.
on on net
In case of measured values, this document gives the methods for testing heat pumps, air conditioners and
liquid chilling packages at part load conditions.
The standard rating conditions and test methods are given in EN 14511-2, EN 14511-3 and EN 15879-1.
The standard provides test procedures for the rating of individual indoor units, as part of multi-split
systems having a system capacity > 12 kW.
Although this document was prepared in the frame of the Commission Regulation (EU) No 206/2012 of
6 March 2012 implementing Directive 2009/125/EC of the European Parliament and of the Council with
regard to ecodesign requirements for air conditioners and comfort fans, it may also be used to show
compliance with the requirements of the European Directive 2010/30/EU and Commission Delegated
Regulation (EU) No 626/2011.
This document was prepared in the frame of the Commission Regulation (EU) No 813/2013 of 2 August
2013 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard
to ecodesign requirements for space heaters and combination heaters. This European standard also aims
at showing compliance with the requirements of the European Directive 2010/30/EU and Commission
Delegated Regulation (EU) No 811/2013.
This document was prepared in the frame of the Commission Regulation (EU) 2015/1095 of 5 May 2015
implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to
ecodesign requirements for professional refrigerated storage cabinets, blast cabinets, condensing units
