Briefs: Water savings thanks to hybrid condensers
Hybrid condensers offer significant water savings versus traditional water-cooled and evaporative condensers. They also make it possible to reduce energy consumption and refrigerant charge. In Australia, where water savings are a major issue since...
The Canadian HVAC Market. First quarter 2014
According to the Heating, Refrigeration and Air Conditioning Institute of Canada (information provided by ReportLinker), air-handler sales showed the largest increase in the first quarter of 2014.
COVID-19 news in the HVAC&R sector
The IIR reviews the available information on the possible impact of air conditioning on the spread of COVID-19 and the recommendations for the operation and maintenance of HVAC systems. Furthermore, several...
PCMs and ice slurries: PCMs: two recent applications
Phase-change materials (PCMs) can provide thermal storage which means that they can absorb thermal energy when they solidify and release it when they melt. This can be very useful to dampen temperature swings. PCMs are usually water-based and are...
Facebook profiles cooled down through polar wind (in French)
The cooling of servers which process most of the data published on our walls uses polar wind.
World HVAC equipment demand to reach USD 122 billion through 2020
According to a new study published by Freedonia, global demand for HVAC equipment is forecast to increase at a 4.1 % yearly rate through 2020 to USD 122 billion.
World air-conditioning market in 2013
In 2013, the world air conditioning market was valued at USD 91.6 billion; grew over 6% compared with USD 86.8 billion in 2012, evidence that the global AC market is finally showing an upturn.
Successful test of a dilution refrigerator for quantum computers
