Energy storage system thermal simulation case

Is insulated case a good model for energy system optimization?

The deviation is noticeably lower for the insulated cases. The model is well suited for energy system optimization in an early planning stage where it is simulated together with other system components to derive the component dimensions.

Can commercial heat exchangers be used as PCM thermal storage systems?

Medrano, M. et al. Experimental evaluation of commercial heat exchangers for use as PCM thermal storage systems. Appl. Energy 86, 2047–2055 (2009). Zauner, C. et al. Experimental characterization and simulation of a fin-tube latent heat storage using high density polyethylene as PCM. Appl. Energy 179, 239–246 (2016).

What is the experimental data collection and measuring system for heat storage?

The experimental data collection and measuring system for heat storage was created for controlling the processes, monitoring the state of the storage, and collecting the data for analyses and model validation. The National Instruments system was used to collect and store the measured data.

Which library is best for building energy simulations?

The Buildings library (Wetter et al. 2014) is one of the most used libraries in both academia and industry for district energy simulations. It includes several tank models for simulating 1-D stratified storages. Yet, these models are restricted to residential applications (i.e., building energy systems).

What is a latent heat thermal energy storage (lhtes)?

A latent heat thermal energy storage (LHTES) tackles this disadvantage by using phase change materials (PCMs). PCMs are substances that change their phase (between liquid and solid usually) in a narrow temperature range and this change is associated with significant thermal energy release or absorption.

Which software is used for heat transfer in storage tanks?

The analysis shows that ANSYS Fluent is the most widely used software for specific heat transfer phenomenon in storage tanks, while self-developed models with simplified terms are evaluated as more flexible and easier to apply. For hybrid systems, self-developed MATLAB, mature parts in ESP-r, TRNSYS, and EnergyPlus are compatible.
