Abstract

The purpose of this study is to develop an operating method of geothermal heat pump system to prevent waste of energy due to inefficient operation. As the interest in energy saving is increasing, the development and use of renewable energy systems is increasing. In korea, While the geothermal system with excellent performance is installed, the other heat source system is used as the main heat source, or the system operates in the partial load state, resulting in waster of energy by controlling the fixed flow rate of the geothermal circulation water. Therefore, the purpose of this study is to develop an operating method of several geothermal heat pump system through the variable water flow rate control method of circulation pump. The proposed operating method is tested through simulation.
