Phase change energy storage air treatment device

Are phase change material based thermal energy storage devices suitable for air-conditioning applications?

This work concerns performance enhancement of phase change material (PCM) based thermal energy storage (TES) devices for air-conditioning applications. Such devices have numerous potential applications in the building environment.

How to maximize the performance of a phase change heat storage device?

Hence, to maximize the performance of the phase change heat storage device, coupling the multistage PCM package with other enhanced heat transfer methods is often necessary. Li37introduced a novel thermal energy storage approach that utilizes CLHS to mitigate thermal energy losses in an adiabatic compressed air energy storage 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.

Are phase change thermal storage devices better than sensible heat storage devices?

ABSTRACT: In comparison with sensible heat storage devices, phase change thermal storage devices have advantages such as high heat storage density, low heat dissipation loss, and good cyclic performance, which have great potential for solving the problem of temporal and spatial imbalances in the transfer and utilization of heat energy.

Why is enhanced heat transfer important in phase change thermal storage devices?

However, there are also issues such as the small thermal conductivity of phase change materials (PCMs) and poor efficiencyin heat storage and release, and in recent years, enhanced heat transfer in phase change thermal storage devices has become one of the research hotspots for optimizing thermal storage devices.

What is a three-tube phase change thermal storage structure?

The three-tube phase change thermal storage structure offers a significantadvantage over the single-tube structure due to its larger heat transfer area per unit length and higher overall flow rate in the annular area, thereby enhancing the heat exchanger’s heat exchange efficiency.
