Performance Assessment of a Ground-coupled Heat Pump for an Office Room Heating using Radiator or Radiant Floor Heating Systems

The ground-coupled heat pump (GCHP) system used to provide space heating for an office room is a renewable technology with a high performance. The experimental measurements are used to test the performance of a GCHP system integrated with the radiator or radiant floor heating system for an office room. A comparative analysis of the main performance parameters (energy efficiency and CO2 emissions) is performed for the two heating systems. Additionally, two numerical simulation models of useful thermal energy and the system coefficient of performance (COPsys) in heating mode are developed using the TRNSYS (Transient Systems Simulation) software. Finally, the simulations obtained using TRNSYS software are analysed and compared to the experimental data, resulting in good agreement and thus the simulation models are validated.
