Community Geothermal: Seward Alaska Heat Loop District Energy System Modelica Model

This dataset contains a Modelica-based dynamic thermal simulation model of the Seward Heat Loop project. The model contains building loads generated from DesignBuilder simulations of the four city-owned buildings that are connected to the system. These buildings are heated by a hydronic hot water district heating system located in the library basement, with heat generated by CO2-based heat pumps, and energy sourced from the nearby Resurrection Bay. The dynamic model is based on the performance data of an actual heat pump shortlisted for the project, specific control strategies planned to be implemented in the operational phase of the project, and temperature profile data of the heat source measured over 8 months. The model simulates the system?s thermal performance and is used to evaluate the system design.
