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. 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 [...]
