AIRAH have released a technical resource on air conditioning load estimation.
The resource, Comfort and Critical Design Conditions–Air Conditioning Load Estimation, according to the AIRAH website, “outlines the basis of post-1990 and pre-1990 Australian Critical/Comfort data sets and provides information on how to interpret the data sets in the two Critical/Comfort outdoor design condition spreadsheets.”
The resource provides specific design conditions for both the post-1990 and pre-1990 data sets. The design conditions for the post-1990 data sets include: more than 800 locations around Australia, climatic data within the range 1990 to 2013 from the Bureau of Meteorology (BoM), pre-1990 locations where the BoM is still recording climatic data, additional locations where the BoM is now recording climatic data and data for summer and winter design conditions. In comparison, the design conditions for the pre-1990 data sets include: more than 570 locations around Australia and in certain overseas locations, 1970-1980s climatic data from the BoM and overseas meteorology institutes and summer and winter design conditions.
The Comfort and Critical Design Conditions–Air Conditioning Load Estimation resource, as well as the post-1990 and pre-1990 data sets can be found here.
This marks the third technical resource that AIRAH have released this year, the others being an update on ‘the use of ventilation and air conditioning in buildings–Part 1: Fire and smoke control in buildings” and a technical bulletin on fire safety in kitchen hood exhaust systems.
