On the 30th June, IEA held a webinar with the title: Residential Test Methods for Air Conditioners.

Some background

Energy consumed by air conditioning systems has tripled since 1990: no other building end-use is growing as fast. Air conditioning not only makes up a significant and growing share of energy consumption, it is also the primary contributor to peak demand in many geographies.

Across the globe there are numerous governing bodies that currently regulate and test air conditioners (ACs) and more than 60 countries have regulatory requirements on the energy performance of ACs. Inverter technologies are proven, cost-effective strategies with potential to slow the growth of energy consumption and reducing peak demand on electrical systems around the world. Successful deployment of these technologies depends on accurate and repeatable test procedures in order to properly rate competing air conditioners on a level playing field.

However, the test procedures and metrics established by these different governing bodies often vary, making it difficult to compare the energy performance of air conditioners, across jurisdictions. This can confuse consumers, and provide misleading drivers for product developers, and increase the testing burden on manufacturers attempting to comply with many different regulatory schemes.

The testing of increasingly popular variable capacity air conditioners (“inverters”) has also presented significant challenges for manufacturers and regulators, and work is underway in several regions to develop advanced methods for testing these products.

Commencing in 2019 and continuing into 2020, 4E commissioned an examination of current test procedures and metrics across its Member countries. The resulting publication identified several recommendations to improve international alignment and better understand the issues around new test methods for variable capacity air conditioners.

The webinar highlighted key findings from the report.
