| Since the20th century, with the continuous development of economic, energyand environmental issues become increasingly prominent, the development ofrenewable energy is the urgent need to solve our energy crisis and environmentalissues. Surface water source heat pump is a use of the scattered low heat in the Earth’ssurface waters of renewable energy technologies, surface water source heat pump willreceive more attention in this context, the use of surface water source, water source,ground source renewable energy heat pump air conditioning not occupy the mainposition of the air-conditioning market, but from the perspective of the developmentof the developed countries, surface water is the main direction of China’s futureenergy efficiency in buildings. China’s Yangtze River, the rivers, lakes and seasurface water resources are very rich, very favorable conditions for the use of surfacewater source heat pump. In this paper, Hefei instance of a closed surface water sourceheat pump works as the research object, based on the measured temperaturedistribution of the surface water bodies, water temperature distribution after therunning of the simulation analysis of heat pump units, analysis of the Hefei surfacewater body heat utilization in different seasons.First describes the working principle of the surface water source heat pump, themain application form and characteristics, outlines the advantages and disadvantagesof the surface water source heat pump, and raise a number of problems of surfacewater source heat pump technology and promote the application.Chapter III analyzes the importance of water and climatic conditions of thesurface water source heat pump, Introduce Hefei climatic conditions and waterconditions. Sort out Hefei annual temperature distribution, combined in Hefei winterand transitional season water temperature stratification, analysis of the degree ofutilization of Hefei heat water in different seasons. An overview of the project, thedesign parameters and air-conditioning gives a brief introduction.Chapter IV introduces the temperature of the water testing program on theproject site and the thermometer, measuring the water temperature of the water atdifferent depths to conduct a comprehensive, on-site test data summarizing analysis,summarized the law of changes in water temperature.Finally, statistical analysis of Hefei outdoor temperature distribution in recentyear, and the project to establish a physical model of surface water source heat pump, for different seasons climate change, the change in temperature of the water bodysimulation of surface water source heat pump is running. Solution is given in the caseof heat does not meet the seasonal use of surface water bodies. |
