| Abstract |
Standing column well(SCW) in ground water heat pump(GWHP) system that is well known for the high efficient heating and cooling system was introduced in Korea 2004, and has been applied in large facilities. Therefore the research of optimum planning of the standing column well for small facilities should be made. Accordingly, this research is aimed to understand the characteristics of underground water as heating and cooling source of the standing column well system that is applied in a small building in accordance with operation methods during heating and cooling. And these results also offers DB(database) for planing of the efficient standing column well systems, which are able to prevent the waste of underground water. For this research, the thermocouples were installed at 10 spots in the well, and the data on temperature of underground water were collected through the data logger all the year round. And temperature changes of the underground water were analyzed by shifting the operation methods of the standing column well system. Differences in the temperature of underground water in accordance with operation methods are clearly defined. Therefore, these findings are expected to contribute to constructing DB required for the optimum planning of small-scale SCW in GWHP system. |
