Information

This model validates the models Buildings.Templates.Components.HeatPumps.AirToWater and Buildings.Templates.Components.HeatPumps.WaterToWater in a configuration in which the heat pump components are exposed to a constant differential pressure and a varying return temperature.

The AWHP model (suffix Aw) is configured to represent either a non-reversible heat pump (suffix Nrv) or a reversible heat pump that switches between cooling and heating mode.

The WWHP model (suffix Ww) is configured to represent a reversible heat pump that switches between cooling and heating mode.

The polyvalent unit model (suffix Php) switches between cooling-only, heating-only and simultaneous heating and cooling mode.
