Fig.: Exploded diagram of an electrochemical compressor cell. To a layman, a heat pump seems to magically draw heat from thin air. But behind that perceived magic is a construction with mechanical compression of fluids, supplying the work needed for useful heating and cooling. This article presents an alternative...

Eight finalists are now selected for the Global Cooling Prize. Seven of the solutions are using technologies to remove humidity from the air, which makes cooling less energy intensive. The eighth solution uses phase transition in crystals to change temperature. The Global Cooling Prize is initiated by Rocky Mountain Institute....

Improved energy efficiency at global scale is necessary to reduce greenhouse gas emissions. But the current trend is disheartening. According to analyses by the International Energy Agency, IEA, a 3% yearly improvement of the efficiency rate is a minimum needed to keep up the energy efficiency pace. But after three...

On 22 – 23 October 2019, the heat pump world met in Nuremberg, Germany. International experts, even from outside Europe, attended to discuss the European heat pump market, technology and application trends. Product and organization presentations at the Foyer-Expo supplemented the variety of information provided by the speakers. EPEE -...

With renewable energy sources the electricity production becomes more variable and unpredictable, causing an imbalance between supply and demand. But balance is necessary. A possible solution to this is demand flexibility: making the electricity demand follow the supply, rather than the traditional way, the other way around. Such demand flexibility...

Data centres are known for producing excess heat. The new centre in Appenzell, Switzerland is no exception: in full operation it could provide the district heating network with approximately 1.5 MW excess heat. But the benefits don’t end there. Thanks to the installation of a high-temperature heat pump, the excess...
