Nov. 26, 2007 – Given the critical importance of energy and cost savings, the application of engineering and management principles has the potential to reshape the design of modern heat pump systems. Microchannel heat exchangers, ejectors, and injection-compressors are some of the latest more interesting developments in heat pump components that boost up the energy […]

Nov. 26, 2007 – The air conditioning industry faces a constant challenge to provide higher effi ciency levels and greater equipment reliability. This challenge is even more difficult to meet when the goal is simultaneously to maintain equipment size and limit potential cost impact. Previous engineering solutions designed to satisfy these requirements have typically included […]

Nov. 26, 2007 – The present development of the heat pump market is extremely interesting: in regions such as Japan and the US, where the market is dominated by air-to-air units, ground-coupled systems are obtaining an increasing share, while in regions such as Central and Northern Europe, which are dominated by groundsource systems, air-source systems […]

Dec. 05, 2007 – Development of air conditioning products to address environmental and air pollution concerns is now an imperative for the industry. Heat exchangers, which are widely used in room air conditioners, packaged air conditioners, heat pump water heaters and other applications, are one of the most important components and affect the performance, reliability […]

Oct. 26, 2007 – Technische Universität Darmstadt is the overall winner of the 2007 Solar Decathlon. This competition challenges 20 college teams from around the world in 10 contests to design, build and operate the most livable, energy-efficient, completely solar-powered house. Solar Decathlon houses must power all the home energy needs of a typical household […]

Nov. 20, 2007 – The renovation of ASHRAE headquarters is expected to be completed in June 2008 at an estimated cost of $5.4 million. Once completed, the renovated building in Atlanta will feature two separate HVAC systems as part of its role as living lab. Level one of the building will be equipped with air-cooled […]

Dec. 03, 2007 – The overall effi ciency of a heat pump system is highly dependent on the performance of the compressor. Compressors in heat pumps not only encounter a wider range of operating conditions than in traditional air conditioners, but also have two to three times longer run times per year than compressors for […]

Oct. 19, 2006 – Individual, advanced training is essential for succeeding in todays knowledge society. Following that trend, more than 200 installers have completed the training course for “certified heat pump installers”. In succession, 65 installers took the opportunity and applied for certification – which means, that they will be certified for three years and […]

Nov. 10, 2006 – The Interreg III project “Information Connection Renewable Energy Sources” (iCON-RES) is a bilateral activity aimed at transfer of know-how and information on renewable energy sources across national boundaries. Contracting body is the city of Vienna, coordinator Arsenal research, Vienna. In cooperation between project partners from Austria and Hungary information materials obout […]
