Full title and description

ISO 16358-1:2013/Amd 2:2024 — Air-cooled air conditioners and air-to-air heat pumps — Testing and calculating methods for seasonal performance factors — Part 1: Cooling seasonal performance factor — Amendment 2. This amendment updates and clarifies requirements in ISO 16358-1:2013 for determination of the cooling seasonal performance factor of air-cooled air conditioners and air-to-air heat pumps used for rating, comparison and certification purposes.

Abstract

This amendment (Amendment 2, 2024) to ISO 16358-1:2013 provides revisions to the test conditions, calculation procedures and related rules used to determine the cooling seasonal performance factor (seasonal efficiency) of air-cooled air conditioners and air-to-air heat pumps. It is intended to be used with the parent standard and referenced standards (for example ISO 5151, ISO 13253 and ISO 15042) and applies specifically to rating and comparison tasks rather than to product design or installation guidance. The amendment is concise (2 pages) and supplies changes/additions necessary to keep the seasonal performance calculation methods current with industry practice and related standards.

Scope

This amendment modifies ISO 16358-1:2013 (Part 1: Cooling seasonal performance factor). It revises or adds specific test conditions, clarifications to calculation methods and/or editorial corrections that affect how the cooling seasonal performance factor is determined for air-cooled air conditioners and air-to-air heat pumps. The amended clauses are intended for use when marking, certifying or comparing seasonal performance according to the referenced rating conditions of the parent and referenced standards.

Key topics and requirements

• Revisions to test conditions and mandatory seasonal test points for cooling seasonal performance factor (CSPF) determination.
• Clarifications to calculation procedures for seasonal performance factors and weighting of test points.
• Alignment and cross-references with ISO 5151, ISO 13253 and ISO 15042 for rating/test conditions.
• Rules for applying the amendment to existing test data and to certification/labeling activities.
• Editorial and technical clarifications intended to improve repeatability and comparability of seasonal performance results.

Typical use and users

This amendment is used by HVAC product manufacturers, test laboratories, certification bodies, regulatory agencies, standards committees and consultants involved in performance testing, energy labeling and compliance verification for air-cooled air conditioners and air-to-air heat pumps. It is relevant when producing rated seasonal performance data for product datasheets, certification submissions or comparative product assessments.
