.Buildings.DHC.Loads.HotWater.StorageTankWithExternalHeatExchanger .Buildings.DHC.Loads.HotWater.StorageTankWithExternalHeatExchangerThis model implements a heating hot water tank with external heat exchanger that heats domestic hot water.
The storage tank model is described in Buildings.Fluid.Storage.StratifiedEnhancedInternalHex. The heat pump and storage tank system should be parameterized altogether using Buildings.DHC.Loads.HotWater.Data.GenericDomesticHotWaterWithHeatExchanger.
It is based on Fig. 3 in Evaluations of different domestic hot water preparing methods with ultra-low-temperature district heating by X. Yang, H. Li, and S. Svendsen at doi.org/10.1016/j.energy.2016.04.109, as well as the Advanced Energy Design Guide for Multifamily Buildings-Achieving Zero Energy published by ASHRAE in 2022 at https://www.ashrae.org/technical-resources/aedgs/zero-energy-aedg-free-download.
For a model that connects this hot water system to a heat pump, see Buildings.DHC.ETS.Combined.Subsystems.HeatPumpDHWTank.
