Jun. 27, 2007 – Conventional thermally powered water heaters are 80 to 95% efficient. The new thermally powered heat pump (TPHP) reported herein is over 140% efficient. In addition, the cold end of this TPHP produces useful chilling. The amount of energy-free chilling is equal to the amount of heat pumping. The combination of the […]

Jun. 27, 2007 – Canada Canadian sawmills traditionally deliver 72 million m3 of resinous lumber per year. About 2% are dried using low-temperature heat pumps and the rest through other technologies using bark-, natural gas- or oil-fired boilers as primary energy sources. However, such products are well suited to high-temperature drying. Two hybrid (electricity/fossil) industrial-scale […]

Jul. 03, 2007 – Norway The use of naturally occurring and ecologically safe substances as working fluids in heat pumps represents an environmental friendly and long-term solution to the problems of HFCs. The most important natural working fluids include ammonia, hydrocarbons and carbon dioxide. This article discusses the main characteristics of ammonia heat pumps, and […]

Sep. 06, 2007 – Austria – The association of Austrian Electricity Companies has funded a project with the aim of developing, testing and evaluating a standardised monitoring methodology for heat pump systems. The results should provide a base for heat pump manufacturers, installers, energy providers, stakeholders and funding agencies. In view of political aspirations particularly […]

Oct. 10, 2007 – Netherlands – Energy Research SubsidyAs the Netherlands Government shifts its research strategy focus to the long term, it has identified the built environment as one of five energy research priority areas, now presented as formal energy research programmes. Long Term Research Programme: Built EnvironmentThe built environment research area covers both new […]

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 […]

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. 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 […]
