An independent assessment of the performance of solar cooling technology is now available, following Standards Australia’s publication of the Interim Standard AS 5389 (Int) — 2013 Solar heating and cooling systems—Calculation of energy consumption.
“This Interim Standard is a world-first and sets out a method of evaluating the annual energy performance of solar cooling and heating systems,” said Colin Blair, Chief Executive Officer, Standards Australia.
Mr Blair said the standard uses test results for components, and a mathematical model, to determine the amount of supplementary conventional energy needed to provide comfort in a standardized Australian home in a range of Australian climates.
The procedure is applicable to solar air conditioners capable of space heating, cooling or both; with or without water heating. This Interim Standard covers testing and reporting of the energy performance characteristics of desiccant-based air conditioners.
Standards Australia expects the Interim Standard will facilitate increased market support and consumer confidence in solar cooling technology as it provides an independent method to verify performance potential.
The Interim Standard was prepared by the Australian members of the Joint Standards Australia/Standards New Zealand Committee CS-028, Solar Water Heaters.
