This Technical Specification (CEN/TS) was approved by CEN on 24 September 2003 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available. It
is permissible to keep conflicting national standards in force (in parallel to the CEN/TS) until the final decision about the possible
conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,
Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and United
Kingdom.

Foreword
This document (CEN/TS 14825:2003) has been prepared by Technical Committee CEN/TC 113 “Heat pumps and
conditioning units”, the secretariat of which is held by AENOR.
This Technical Specification was first intended to be published as EN standard, but due to the little experience in
this type of testing, the Technical Committee decided to issue it as a TS.
This Technical Specification is published to give the general conditions and requirements for testing. When further
experience will be reached in test methods, the change to EN will be considered.
Annex A is informative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this Technical Specification: : Austria, Belgium, Czech Republic, Denmark,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway,
Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom.

Introduction
Heat pumps, air conditioners and liquid chilling packages are, at present, selected and compared at a rated
condition. This condition does not represent the usual operating conditions of the equipment over a season. This
operating condition can be better assessed by comparing equipment at a representative 50% reduced capacity.
Fixed capacity air conditioners, liquid chilling packages and heat pumps 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 standard gives the rating conditions and methods for testing air conditioners, heat pumps and liquid chilling
packages operating to overcome part load.
The rating conditions and test methods of units operating to overcome full load are given in EN 14511-2 and EN
14511-3.
1 Scope
This Technical Specification covers testing of air conditioners, heat pumps and liquid chilling packages for part load
conditions.
It specifies the terms, the definitions, the methods for testing and reporting, and the calculation method for the
cyclic and compressor reduced capacity. The temperature and system reduced capacities are excluded.
This European Standard applies to factory made units defined in EN 14511-1.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies (including amendments).
