Recirculation Technical And Economic Analysis Of Water Source Heat Pump In Severe Cold Area

As in recent years the area of application of water source heat pump system in our country is gradually popularized, many projects for the national energy conservation policy and government subsidies were not according to its geological conditions and was blindly invested and used, which made a lot of failed projects. Many domestic experts and scholars are skeptical of energy-saving and economy of the project. According to the characteristics of water source heat pump system in this paper, the principle of water source heat pump system is briefly introduced, and a brief analysis of the application conditions system was made. It analyzed recharge clogging problems and introduced several solutions of injection plugging problem. Through the analysis of detection of two actual project, it does the amount of energy substitution analysis, environmental benefits and economic benefits analysis. In the process of this, we have an intuitive definition of high efficient, economic and energy saving of the water source heat pump technology, in order to better promote the popularization and application of the technology.The core technology of water source heat pump technology is groundwater extraction and recharge. This paper introduces basic principle of water source heat pump,the types of recharge well, the reasons of producing recharge clogging, and summarizes some solutions of recharging well clogging. Through technicians and field detections of Jia Musi Technician College and The Second Affiliated Hospital of China Medical University, the paper makes analysis and calculation of the indoor and outdoor temperature, water flow rate, and unit power data for the two project to do a content analysis, conventional energy substitution analysis of environmental benefit and economic benefit analysis.The last part of the paper on the impact of water source heat pump technology on the environment are discussed in this paper, starting from the angle of engineering actual situation and determine the technology of energy saving benefit and environmental benefit, and the water source heat pump technology in the future development trend is prospected.
