Development and Experimental Validation of a TRNSYS Dynamic Tool for Design and Energy Optimization of Ground Source Heat Pump Systems

Abstract

[EN] Ground source heat pump (GSHP) systems stand for an efficient technology for renewable heating and cooling in buildings. To optimize not only the design but also the operation of the system, a complete dynamic model becomes a highly useful tool, since it allows testing any design modifications and different optimization strategies without actually implementing them at the experimental facility. Usually, this type of systems presents strong dynamic operating conditions. Therefore, the model should be able to predict not only the steady-state behavior of the system but also the short-term response. This paper presents a complete GSHP system model based on an experimental facility, located at Universitat Politècnica de València. The installation was constructed in the framework of a European collaborative project with title GeoCool. The model, developed in TRNSYS, has been validated against experimental data, and it accurately predicts both the short- and long-term behavior of the system.The present work has been supported by the FP7 European project "Advanced ground source heat pump systems for heating and cooling in Mediterranean climate" (GROUND-MED), and by the Generalitat Valenciana inside the program "Ayudas para la contratacion de personal investigador en formacion de caracter predoctoral (ACIF/2016/131)". A particular mention is given to the European Community Horizon 2020 Program for European Research and Technological Development (2014-2020), who has covered the costs to publish this work and funded part of this research inside the framework of the project 656889-GEOTeCH (Geothermal Technology for Economic Cooling and Heating).Ruiz-Calvo, F.; Montagud, C.; Cazorla-Marín, A.; Corberán, JM.
