Specific Comments Chillers AHRI supports updating chiller MEPS based on ASHRAE Standard 90.1. Further, AHRI strongly recommends the referencing of AHRI Standard 550/590 (I-P)-2015 with Errata, Performance Rating of Water-chilling and Heat Pump Water-heating Packages Using the Vapor Compression Cycle Effective – on April 1, 2016, or its metric (SI) companion document, AHRI Standard 551/591 (SI)-2015 with Errata, Performance Rating of Water-chilling and Heat Pump Water-heating Packages Using the Vapor Compression Cycle Effective on April 1, 2016. – AHRI also understands that there are discussions in Australia concerning the comprehensiveness and global scope of the AHRI standards and certification program. Specifically, we understand these conversations involve a comparison of the AHRI and Eurovent certification programs3. AHRI is very familiar with the Eurovent program, having established it with European partners more than twenty years ago to address European needs. Despite what may appear to similarities, there are differences between the two programs, with AHRI’s being global4. Certified Data (One vs Operating Map) Eurovent only certifies performance at Eurovent Standard Rating Conditions include ESEER. AHRI certifies the entire operating map of water-cooled products and the entire operating 100% load map of air-cooled products including IPLV. This is critical in terms of the availability of certified data that can be used in building analysis in addition to data at the Standard Rating Condition, which is only a single point of operation of infinite number of points. Certification Program Scope (Small vs Large Range) Eurovent certifies the performance of air-cooled chillers up to 170 tons (600kW) and water-cooled chillers up to 426tons (1500kW). AHRI certifies the performance of air-cooled chillers up to 600 tons (2110kW) and water-cooled chillers up to 3000 tons (10551kW). AHRI provides free certification verification services that will ensure customers’ ratings provided for specific jobs are certified. Testing Requirements (General vs Detailed) Eurovent specifies general testing requirements and laboratory approval. RIS Option B. 3 AHRI 550/590 is one of a suite of AHRI standards currently being adopted by the Kingdom of Saudi Arabia 4 for its MEPS compliance program for commercial air conditioners and chillers.
