Groundwater Source Heat Pump System For Well Optimization And Unit Performance Experimental Study

Entering 21st century, the mankind pays more close attention to the relationship among energy , environment and sustainable development than ever in the whole world. It must utilize clean regenerated energy as much as possible to realize sustainable development, and improve the rate of utilization of energy consumption. Building energy consumption occupies the important part in the total energy consumption of the country, the building energy consumption of the developed country generally takes total energy consumption 30% - 40%,and the proportion of our country is 26.7%. Strengthen building save-energy have a important meaning for sustainable development in our country. GWSHP system make the groundwater as cold source or hot source, and its cop is higher than other air conditioners system, the system can discharge the surplus cold or heat into soil at the same time, so it has higher environmental protection value.This article optimize the well group designs of system and research the influence of difference work mechanisms for GWSHP system through experiment. It is the key question that how does the well group arrange to application GWSHP system and the well group arrangement decided based on the water - heat moving law of GWSHP. This paper comprehensive summarize water - heat moving models on aquifer and sum up the research evolvement that many models and simulation methods apply to environmental science, HVAC and Geological Sciences; Based on this, upon data simulation experiment, find out influence of flow rate at well outlet and the distance between wells on heat penetration, and optimize the placement of wells; eventually analyze the influence of well water temperature at inlet and difference between outlet temperature and inlet's on heat pump's performance, this paper Optimize the well-group profile for GWSHP system and analyse the performance of ground machine, offer the decision basis for design, operation and management of GWSHP system.The sum total of study on the subject is contained in this paper: 1 comprehensive summarize water - heat moving models on aquifer and sum up the...
