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

With the development of national economy and the improvement of living level, the proportion that energy consumed in construction of that consumed in all field is more than before. Tthe main section of the energy consumed in construction is consumed by HVAC system. 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 uses renewable energy.At present, the heating mode in north of China is mostly rely on boiler and district heating. With the property of energy saving and environment protection, GWSHP has a large potential as a new type of heating technology. The application of GWSHP involves the efficient utilization and the pollution of underground water source. Because it has not been a long time since the technology was applied in China, people lack overall system understanging about the applying situation and relative problem of the technology.This thesis mainly research the use of GWSHP heating system in Shenyang. Obtain lots of field-test data by surveying the operation of some typical GWSHP systems continuously. The theory analysis is combined with the field-test data in this paper for the sake of reserching COP and efficiency of exergy. Then evaluate the performance of the GWSHP system.In order to research the heating economy capability, the thesis gives an example in Shenyang and compare GWSHP system with other two projects. The conclusion is that GWSHP system has a large invest and maintenance cost but its operation cost is the least. So its heating cost is the most economical.At last this thesis establish the math model of GWSHP heating system and simulate its performance by SIMULINK. The result of simulation can be used in designing system control manner.
