PCM-Phasenwechsel-Energiespeichersimulation
Unsere faltbaren Photovoltaik-Energiespeichercontainer setzen neue Maßstäbe in der mobilen und nachhaltigen Energieversorgung. Mit einem durchdachten Design und robuster Technologie bieten wir skalierbare Lösungen für flexible Einsatzorte – ob in der Notstromversorgung, auf Baustellen oder in entlegenen Regionen.
Dank der leichten Transportierbarkeit, schnellen Inbetriebnahme und modularen Struktur sind unsere Container die ideale Lösung für die autonome Stromversorgung ohne feste Infrastruktur. Durch die Kombination aus Solarpanelen und innovativer Speichertechnik ermöglichen wir zuverlässige Strombereitstellung – jederzeit und überall.
Zyklusstabilität – darunter versteht man einen reproduzierbaren Phasenwechsel, ohne dass sich die Materialeigenschaften ändern. In der Regel möchte der Anwender den Werkstoff ohne Einschränkungen bis auf Lebenszeit der Wärme- oder Kälteversorgungsanlage betreiben. Chemische Beständigkeit des PCM – sie garantiert
What is a phase change material (PCM)?
Phase change materials (PCM) In the configuration of an LTES unit, selecting an appropriate storage medium is crucial for the desired application. The phase change material (PCM) chosen must exhibit specific thermophysical, chemical, and kinetic properties.
How does a PCM reduce transient peak heat load?
During the heating OFF state, the stored heat within the PCM is released and conducted out. The analysis shows that the PCM buffers heat spikes from the heat source and reduces the transient peak heat loads by 50% for the heat rejection system.
Why does microencapsulated PCM have a lower heat transfer rate?
Because PCM is solid at the shell edges and liquid at the core, microencapsulated PCM has lower heat transfer rates . The LHTES system's energy storage relies on the PCM's thermal conductivity. Pure PCM (excluding metallics) has minimal thermal conductivity.
What is PCM thermal storage?
PCMs have extensive application potential, including the passive thermal management of electronics, battery protection, short- and long-term energy storage, and energy conversion. In this work, we presented a comprehensive overview of PCM thermal storage at the multi-physics fundamental level, materials level, device level, and systems level.
What is PCM encapsulation?
In the early 1940s, Barrett K. Green developed PCM encapsulation, which is categorized as shown in Fig. 7. The isolation of PCMs is achieved by encapsulation. By their construction, encapsulated PCM can be categorized as shape and core-shell stability . Core-shell PCMs enclose PCM particles in a core coated by another material.
How do PCMS affect energy solidification?
Many studies have been conducted to determine the appropriate PCMs. Gong and Mujumdar analyzed the impact of PCMs' thermophysical characteristics on energy solidification. They found that reducing thermal conductivity and diffusivity ratios enhanced the energy discharge rate.
