65 This document EN 14825:2022/prA1:2023 has been prepared by Technical Committee CEN/TC 113
66 “Heat pumps and air conditioning units”, the secretariat of which is held by UNE.
67 This document is currently submitted to the CEN Enquiry.
68 This document will amend EN 14825:2022.
69 EN 14825:2022/prA1:2023 includes the following significant technical changes with respect to
70 EN 14825:2022:
71 — Correction of normative references to EN 14511.
72 — Corrections of errors in the published edition.
73 — A new Annex N with a controls verification procedure (CVP) test to verify the compressor frequency
74 at part load condition D.
75 — A new Annex O for indoor unit airflow rate measurement, setting and verification for air-to-air units
76 with a rated capacity of ≤ 12 kW.
77 This document has been prepared under a standardization request addressed to CEN by the European
78 Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
79 Member States.
80 For the relationship with EU Legislation, see informative Annexes ZA to ZF, which are an integral part of
81 EN 14825:2022.
82 Introduction
83 The incoming changes in the revised Regulation (EU) 206/2012 for testing air-to-air air-conditioners and
84 heat pumps introduce the airflow limitation to make sure thermal comfort is considered, and the controls
85 verification procedure (CVP) to certify the compliance of testing of units covered by EN 14825 by market
86 surveillance.
87 The incoming changes in the revised Regulation (EU) 813/2013 for testing air to water, water (brine)-to-
88 water (brine) and DX/water (brine) introduce the controls verification procedure (CVP) to certify the
89 compliance of testing of units covered by EN 14825 by market surveillance.
90 As such, indoor unit(s) airflow measurements and CVP need to be considered and included in EN 14825.
91 This amendment considers the following:
92 1) Controls verification procedure (CVP) test to verify the compressor frequency,
93 2) Indoor unit airflow rate measurement, setting and verification for air-to-air units with a rated
94 capacity of ≤ 12 kW.
