Research Of Ground Water-Source Heat Pump Air Conditioning System Applied In Beijing

With the development of national economy and the improvement of living level, the air-conditioning technology is applied in industial building, commercial building and domestic building widely. The energy consumed in construction is more than one third of that consumed in all field and the main section of the energy consumed in construction is consumed by air-conditioning system. So the wide application of air-conditioning technology makes the energy consumed in construction increase rapidly. Energy is not only the material guarantee of rapid economic development, but also the source of pollution. The increasing of energy consumption means the intention of environmental pollution. Today, the shortage of energy and environmental pollution are the most serious questions that threaten our lives.The ground water-source heat pump (GWSHP) air-conditioning technology appears with the requirement of both energy saving and environment protection. It uses the underground water as the heating source in winter and the cooling source in summer. It is an efficient technology that makes use of renewable energy.It is the fast developing period of construction in Beijing. It becomes the people's concern that to seek environmental and energy saving air-conditioning system. The application of GWSHP air-conditioning technology involves the efficient utilization and the pollution of underground water source. Because it has not been a long time since the technology was applied at home and abroad, people lack overall, system understanging about the applying situation and relative problem of the technology.So, the research of several typical GWSHP air-conditioning system is carried out in Beijing, including Jiaheliyuan apartment building, Youyi hospital and Changping police university. The system applied in Jiaheliyuan apartment, which is a Sino-U.S. demonstration project, is researched and analysised as the main object. The operation of the system in 3 years is followed and surveyed, and a lot of field-test data are obtained.The theory analysis is combined with the field-test data in this paper, and...
