Can thermal energy storage be integrated into low-temperature heating & high- temperature cooling systems?

The present review article examines the control strategies and approaches, and optimization methods used to integrate thermal energy storage into low-temperature heating and high-temperature cooling systems. The following are conclusions and suggestions for future research and implementation in this field:

What is a cold thermal energy storage (CTEs) system?

The focus of the present review is on latent TES systems using PCM for the temperature range covering AC applications (20 °C) to low-temperature freezing of food (−60 °C). For these applications, the integrated TES units are commonly referred to as cold thermal energy storage (CTES) systems.

Why is air cooling a problem in energy storage systems?

Conferences > 2022 4th International Confer... With the energy density increase of energy storage systems (ESSs), air cooling, as a traditional cooling method, limps along due to low efficiency in heat dissipation and inability in maintaining cell temperature consistency. Liquid cooling is coming downstage.

What is active storage in HVAC systems?

As illustrated in Fig. 7, active systems are classified into storage in the HVAC system, storage in the building structure, and storage in the surrounding area of the building. Active storage in HVAC systems refers to the storage used for both heating and cooling purposes with the combination of the HVAC system.

What is a sensible heat storage system?

Sensible heat storage involves storing thermal energy by altering the temperature of the storage medium. In a latent heat storage system, heat is released or absorbed during phase changes within the storage medium.

How to choose a display cabinet with an integrated PCM cold storage unit?

The commonly set performance criteria to evaluate the appropriate display cabinet with an integrated PCM cold storage unit are: Reduction in the energy consumption by up to 5% and reduction in the peak cabinet air temperature during the defrosting period by up to 2 K.
