Innovative Groundwater Heat Pump System for Space Heating and Cooling in USA and China

Abstract

A groundwater heat pump system based on original, innovative technology for the development and utilization of shallow ground water – the “Single Well System” (HYY SWS) is presented. It was developed by the Beijing Ever Source Science and Technology Development Co., Ltd (HYY) to provide buildings with heating and cooling, as well as with domestic hot water. The system characteristics and operational experience has been reported at conferences including WGC2005 and Renewable Energy 2006. So far, the HYY SWS has mainly been installed in China, with one system operating in Mongolia. In 2008, the first SWS was designed and implemented in the USA. It is located in Baker City, Oregon and is designed to supply heating and cooling to a Behlen Manufacturing Co. factory building (1,115 m2). The system is now in regular operation.

SWS systems were installed for several of the 2008 Summer Olympic Facilities in Beijing: Olympic Village National Gymnasium (80,000 m2), Athlete Mansion Hotel and Scientific Research Building (64,382 m2), Tennis Center (26,541 m2), Hockey Training Facility (11,851 m2), and Bicycle Training Facility (6,049 m2). All operate satisfactorily.
