6 FAQs about [Phase change energy storage in food freezer]

Can phase change materials improve the thermal performance of commercial freezers?

The issue of improving food storage applies at different applications such as commercial freezers or refrigerated trucks. The aim of this work is to improve the thermal performance of commercial freezers using phase change materials (PCMs) under door openings and electrical power failure.

What happens when phase change materials are used for energy storage?

The temperature of the chamber will either remain constant or fall as a result of this. When phase change materials (PCMs) are used for energy storage, the charging and discharging of thermal energy is more efficient. In these materials, thawing point temperature, sublimation, evaporation, or other states are specified.

What is cold energy storage using phase change material (PCM)?

Cold energy storage using phase change material (PCM) is an advanced energy technology. Many researchers have investigated saving energy and energy efficiency improvement by the use of PCM in domestic refrigeration , freezers , and refrigeration plants .

How to improve the performance of the freezer?

One of the methods proposed and used to improve the performance of the freezer is the use of phase change materials (PCM). In PCMs, thanks to the high latent heat, they have become suitable materials for some storage activities.

Does cold thermal energy storage by PCM for freezers work?

This research tries to conduct a comprehensive study on cold thermal energy storage by PCM for freezers and by simulating the freezer system and placing PCM inside it, the effect of PCM in the system is studied. It also shows the difference between a system in the presence of PCMs and a system in the absence of PCMs.

What happens when a PCM is present in a freezer chamber?

The presence of PCM in the freezer chamber causes the PCM to receive the heat energy of the chamber to supply phase change energy. The temperature of the chamber will either remain constant or fall as a result of this. When phase change materials (PCMs) are used for energy storage, the charging and discharging of thermal energy is more efficient.
