Innovative heat pump technologies - for a greener world! - IEA Heat Pump Centre Newsletter vol. 33, No.4/2015
News and views in the recently released issue of the Heat Pump Centre Newsletter:
Innovative/alternative/non-conventional HP technologies
The principle of vapor compression is a dominating technology for heat pumping equipment, and has been so for a long time. However, the common refrigerants used generally have large values for Global Warming Potential, while alternative refrigerants generally have other drawbacks. Although significant work is being done to develop new refrigerants and refrigerant blends, another way forward is to use alternative heat pumping technologies.
Some of these technologies are presented in the new issue of the Heat Pump Centre Newsletter. The Foreword provides an introduction to the three topical articles, each focusing on one of the most promising of the new technologies. The Column presents project ideas regarding heat pump noise. Of the two non-topical articles, one gives an overview of Thermal Response Testing for Ground Source Heat Pumps, while the other one reveals the early history of the Japanese Eco-Cute heat pump. We are also given a Strategic Outlook article from China.
