B-47 Development of System Simulation Models for Ground Source Heat Pump System : Part 1 Micro Model considering ground thermal conduction based on cylindrical coordinate

Abstract

This study aims for development of the simulation models for ground source heat pump system in order to apply practical tool to designer. The developing models are composed of two editions which can be used according to the purpose of use. Also the models are developed on EXCEL sheet, can be coupled with LCEM tool, to make easy to use. In this paper, one of edition which considers ground thermal conduction is discussed; this edition can calculate temperature of ground surround ground heat exchanger and heat source water temperature based on cylindrical coordinate. The calculation algorisms used on this model are shown and the test calculation results are shown.
