.Buildings.Fluid.SolarCollectors.BaseClasses.PartialSolarCollector

Information

This component is a partial model of a solar thermal collector. It can be expanded to create solar collector models based on either ASHRAE93 or EN12975 ratings data.

• February 4, 2025, by Jelger Jansen:
  Use nPanels_internal when calculating nPanelsPar_internal and nPanelsSer_internal. Only request nPanelsPar as an input for an array of collectors and add assert to check if the total collector area is an exact multitude of a single collector's area. This is for IBPSA, #1956.
• February 27, 2024, by Jelger Jansen:
  Refactor model.
  This is for Buildings, #3604.
• December 11, 2023, by Michael Wetter:
  Corrected implementation of pressure drop calculation for the situation where the collectors are in parallel, e.g., if sysConfig == Buildings.Fluid.SolarCollectors.Types.SystemConfiguration.Parallel.
  Changed assignment of computeFlowResistance to final based on dp_nominal.
  This is for Buildings, #3597.
• September 16, 2021, by Michael Wetter:
  Changed lat from being a parameter to an input from weather bus.
  This is for IBPSA, #1477.
• April 14, 2020, by Michael Wetter:
  Changed homotopyInitialization to a constant.
  This is for IBPSA, #1341.
• November 12, 2019, by Filip Jorissen:
  Set prescribedHeatFlowRate=false to avoid a division by zero at zero flow when using SteadyState dynamics.
  This is for Buildings, issue 1636.
• April 27, 2018, by Michael Wetter:
  Corrected displayUnit.
  This is for Buildings, issue 912.
• January 22, 2016, by Michael Wetter:
  Corrected type declaration of pressure difference. This is for #404.
• February 8, 2015, by Filip Jorissen:
  Propagated multiple parameters from LumpedVolumeDeclarations, set prescribedHeatFlowRate = true in vol.
• September 18, 2014, by Michael Wetter:
  Removed the separate instance of Modelica.Thermal.HeatTransfer.Components.HeatCapacitor and added this capacity to the volume. This is in response to https://github.com/lbl-srg/modelica-buildings/issues/276.
• June 25, 2014, by Michael Wetter:
  Improved comments for tilt to address https://github.com/lbl-srg/modelica-buildings/issues/246.
• October 8, 2013, by Michael Wetter:
  Removed parameter show_V_flow in declaration of instance res.
• January 4, 2013, by Peter Grant:
  First implementation.
