Jun. 25, 2008 – For air-to-air heat pumps installed in second and holiday homes in Denmark (more than 200.000 properties) the Danish Electricity Saving Trust has prepared the introduction of a new Energy Saving Label. Six criteria must be fulfilled to qualify for this recommended Energy Saving Label. Source: ScanRef

Jul. 15, 2008 – Geothermal systems operate for 1/2 to 1/4 the cost of most other heating and cooling systems! In January 2006 the U.S. Federal government changed the minimum efficiency for air conditioners to 13 SEER from the previous minimum requirement of 10 SEER. Geothermal systems are up to twice the minimum required efficiency! […]

Jul. 29, 2008 – The German manufacturer Roth Werke GmbH offers a newly developed solar-assisted GSHP system called “Solargeo-Energiesystem”. According to Roth this system provides an efficiency increase of up to 25 percent compared to commonly used GSHP installations. The Solargeo-Energiesystem combines a solar collector, a brine-to-water heat pump and compact geothermal collector packages (Registerstation) […]

Sep. 17, 2008 – The European Parliaments Industry Committee backed EU legislation that targets extensive deployment of renewable technologies, including all types of heat pumps. New rules could also promote, or oblige, the use of renewable technologies in new and existing buildings. The European Parliaments Committee on Industry, Research and Energy (ITRE) voted on 11 […]

Sep. 22, 2008 – California has proposed an extensive set of leak detection, repair, reporting, and retrofitting rules for large air conditioning and refrigeration systems using high global warming F-gases. Facilities using the natural refrigerant CO2 would not be affected by the regulation presented to the public this week. The draft regulation, discussed in three […]

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 […]

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 […]
