Information

Model of a water-to-water heat pump with temperature control on evaporator side, with the heat pump being connected to a domestic hot water tank with fresh water stations.

The heat pump model with storage tank is described in Buildings.DHC.Loads.HotWater.StorageTankWithExternalHeatExchanger. The evaporator hydronics and control are described in Buildings.DHC.ETS.Combined.Subsystems.BaseClasses.PartialHeatPump.

Condenser Controls

The system is enabled when the tank charge control signal switches to true. When enabled,

• the condenser pump is commanded on and supplies the nominal mass flow rate to the tank and domestic hot water system,
• the heat pump evaporator supplies a constant temperature increase from the return to the supply equal to dT_nominal.

Revisions

• November 28, 2023, by David Blum:
  First implementation, extended from partial base class with added condenser hydronics and control. This is for issue 3063.
