Information

Overview

Simple multi-layer thermal energy storage model with volumes as heat exchangers (no pressure losses).

Concept

The water volume of the thermal energy storage can be discretised in several layers.

The following physical processes are modelled

• heat exchange with the environment
• heat exchange over the heat exchanger
• a bouyancy model for the heat transfer between the layers

In contrast to the StorageDetailed model, the following simplifications are taken as a basis:

• Only indirect charging and discharging using a heat exchanger is possible. Thus, there are two separated hydraulic circuits.
• The heat exchanger is an array of volumes without any pressure losses
• There is no optional heating coil and no second heating coil. Hence, the StorageSimple model is limited to a two-circuit application.
