Heating/Piping/Air Conditioning Engineering;Dec2008, Vol. 80 Issue 12, p18
The article reports on the most accelerating trends in the commercial-building industry in the U.S. by using the water-source-heat-pump (WSHP), or thermal-energy-transfer (TET) systems. TET system is composed of standardize heat pumps interconnected of a closed water loop. It satisfies the air-comfort requirements of the zone in which it is located. Information regarding its application techniques and its other usages are included.
