ASHRAE Journal - February 2009 - (Page 10) (Left) The new Grasso V Series attracted crowds at the GEA Refrigeration stand where the company promoted its TCO philosophy: total cost of ownership. (Right) The NürnbergMesse offers 160 000 m² (1.7 million ft2) of display area in 12 halls grouped around the central park. The Chillventa event occupied about half of the halls and drew 30,000 visitors. 300,000 heat pumps are currently operating in Germany. at noise levels of 7 dBA.

The condensing unit is multifamily and commercial systems. “In 2008, 500,000 heat fitted with an innovative fan motor, which prolongs product life pumps were sold in the EU, mostly in the residential and single beyond that of a standard commercial motor. Tecumseh also introduced R-407C/R-22 dual refrigerant RK family housing market. In Sweden, Europe’s most saturated heat pump market, sales figures were already declining for compressors, enabling the upgrade of compressors using R-22 without having to change existing installathe domestic sector.
