Research on the Energy Efficiency Evaluation System for Surface Water Source Heat Pump System in Northeast Cold Region of China

As the rapid development of urbanization in China, the conservation of building energy has become a world trend, the rapid rise of building energy will lead a huge pressure on energy supply and environment protection. Renewable energy sources, like solar and geothermal energy, have the incomparable superiority than conventional energy sources, if renewable energy sources could replace conventional energy source and play a major role fully, the serious energy consumption must be relieved effectively. In this thesis, the summer-refrigeration of SWHP (Surface Water Heat Pump) is set as the research target, the applicability research of SWHP is carried out, apart from that, building the evaluation system and putting forward the level determination method of energy efficiency.
