SHORT-TERM MODELING OF HYBRID GEOTHERMAL SYSTEMS FOR MODEL PREDICTIVE CONTROL

File size: 2mb

Authors: Iago Cupeiro Figueroa, Damien Picard and Lieve Helsen

Highlights

• A simulation study assesses the impact of COP formulation and borefield controller model for model predictive control of a hybrid geothermal system.
• Using an accurate COP formulation presents a smoother and more efficient heat pump behaviour.
• Including a borefield controller model avoids hitting the heat pump safety freezing constraints, improving robustness.
• Despite reducing the number of iterations in the optimisation, the simulation time is increased, however still feasible.

POTENTIAL OF THE MPC HYBRIDGEOTABS CONCEPT FOR BUILDINGS: LIBEZNICE SCHOOL

File size: 587kb

Authors: Yauheni Kachalouski, Jiri Cigler and Lukas Ferkl

As a part of hybridGEOTABS project, Libeznice school is one of several demonstration cases that employs geothermal heat pump with Thermally Activated Building Systems (TABS) combined with Model Predictive Control (MPC) algorithms for heating and cooling. Benefits and potential of such a system is presented in this article.

Abstract
GEOTABS buildings use geothermal energy to heat and cool the building by use of a heat exchanger and heat pump. This energy efficient method can possibly partly give an answer to the changing climate. The thermally activated building system (TABS) are hydronic pipes embedded in the building structure that exchange heat to and from the surrounding concrete in order to heat or cool the rooms. This type of radiant heating and cooling should at the same time provide a comfortable thermal environment. As this system uses moderate supply temperatures and large surfaces for heat exchange, it is expected to be able to create a rather uniform indoor environment for a long time. This technology is up to now mostly present in offices, but research is going on in order to implement it in more types of buildings. This thesis wants to examine if GEOTABS and elderly homes can form a good combination. Therefore research is first done to find what thermal comfort is and how it can be established. In addition, information is looked for to see if elderly experience thermal comfort the same way as younger people or not. In a new elderly home that uses GEOTABS, measurements are done and questionnaires are gathered to gain insight in the existing thermal environment and the experience of the residents. This data is then compared to the stated benefits of TABS concerning thermal comfort and to the design criteria of thermal comfort models. Multiple advantages of radiant heating and cooling systems could be recognised and above all most of the elderly felt comfortable in the elderly home. Nevertheless some improvements can still be made to create an even more comfortable environment. Based on all this information it can be confirmed that GEOTABS are suitable for use in elderly homes.
