Comparison of different configurations of a solar-assisted ground-source CO2 heat pump system for space and water heating using Taguchi-Grey Relational analysis
Sazon, Thor Alexis Salazar; Zhang, Qian; Nikpey Somehsaraei, Homam (Peer reviewed; Journal article, 2023)This work deals with the comparison of different optimized configurations of solar-assisted ground-source CO2 heat pump systems using the Taguchi method and Grey Relational Analysis (GRA) when used for simultaneous space ... -
Development of a surrogate model of a trans-critical CO2 heat pump for use in operations optimization using an artificial neural network
Sazon, Thor Alexis Salazar; Zhang, Qian; Nikpey Somehsaraei, Homam (Peer reviewed; Journal article, 2023)Conventional physics-based models can demand substantial computational resources when employed for operational optimization. To allow faster system simulations that can be employed for operational optimization, a surrogate ... -
Investigation of the performance of a heat pump that uses CO2 as working fluid.
Staurland, Lars Petter Solberg (Bachelor thesis, 2023)Climate change is one of the greatest challenges facing the world today, and reducing greenhouse gas emissions is a critical part of mitigating its impacts. Conventional residential heat pumps use Hydrofluorocarbons (HFCs) ... -
Modeling and investigation of the performance of a solar-assisted ground-coupled CO2 heat pump for space and water heating
Sazon, Thor Alexis Salazar; Nikpey Somehsaraei, Homam (Peer reviewed; Journal article, 2023)The rise in the popularity of heat pumps should be accompanied by the increase in the utilization of environmentally-safe working fluids. To push for wider uptake of hybrid heat pump systems that use natural working fluids, ...
