B-48 Development of System Simulation Models for Ground Source Heat Pump System : Part 2 Development of Macro Model using Logarithmic Function

Abstract

A "macro model" is developed as one of analysis models in system simulation for ground source heat pump systems. The model is targeted for central heat source systems applied ground source partially. Annual hourly variations of heat source temperatures are summarized in simple expressions by using logarithmic functions in the model. The model is applicable for systems with different parameters including ground properties and heat pump efficiencies. It also can be available at the planning stage of GSHP systems and furthermore applied for system simulation for the whole air conditioning systems.
