6 FAQs about [Phase change energy storage in data centers]

Can phase change material be used in sustainable cooling of data centers?

Contamination Control and Air-Conditioning Technology, 4 ( 2014), pp. 49 - 54 Application of phase change material in sustainable cooling of data centers Application of phase change material in sustainable cooling of data centers Plate type heat exchanger for thermal energy storage and load shifting using phase change material Energy Convers.

What are the different types of DC phase change cooling technology?

This paper divides the DC phase change cooling technology into four categories, independent heat pipe cooling, integrated heat pipe cooling, two-phase immersion cooling and cold storage systems. Independent heat pipe system can meet the cooling demand only through the heat pipe without any other mechanical cooling.

How effective is phase change cooling in DC?

Thus, efficient cooling approaches should be applied in DCs to ensure its safe operation and optimize its thermal environment and cooling efficiency. Phase change cooling (PCC) technology is regarded as one of the effective and widely-used cooling methods, which have been applied in DCs for several years.

How to improve efficiency of data center cooling system?

Youshida et al. proposed a novel system incorporating cold supply to data center and heat supply to other facility. In this system, the heat from data center was stored in TES, and supplied to absorber together with post-heating source to enhance the efficiency of cooling system. 5.3. TES integrated free cooling system

Are phase change materials suitable for thermal energy storage?

Phase change materials (PCMs) having a large latent heat during solid-liquid phase transition are promising for thermal energy storage applications. However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/ (m ⋅ K)) limits the power density and overall storage efficiency.

Why should data center cooling system be integrated with cooling system?

Requirement of high security and high cooling load in data centers leads to the development of data centers cooling system as a separate field. TES integrated with cooling systems in data center is usually applied to realize multi-targets including lower cost and higher operational security.
