1. Introduction. The burning of fossil fuels pollutes the atmosphere, and utilizing renewable energy is needed to minimize such impacts. Thermal energy storage (TES) using PCM can store solar energy for later use that is employable in buildings, solar systems, and heat energy recovery systems [1], [2], [3].Latent heat thermal energy
A thermal storage with a shell and tube heat exchanger is used for separating HTF and storage medium in the storage tank. The HTF is pumped into the tube that is submersed in the storage medium. When the system is charged, cold HTF is drawn from the bottom, heated as it passes through a solar collector, and returns to the top of
Sizing procedures are presented for latent heat thermal energy storage systems that can be used for electric utility off-peak energy storage, solar power plants and other preliminary design applications. NTRS Collections About News Help Login. Back to Results. Thermal energy storage heat exchanger:

The heat is released at a constant rate along the energy pile or BHE (borehole heat exchanger), and is transferred by the mechanism of thermal conduction. Thermal properties λ, α are assumed to be the same for the external and internal heat conduction problem, i.e. for r 0 < r, and r 0 > r, respectively, which implies that borehole

The heat exchanger (Hex) in a LAES system using liquid phase working mediums for cold energy storage (CES) works discontinuously for the intermittent characteristic of the LAES. Variable temperature distribution exists in the Hex for CES (Hex-CES) in the intermittent process, and degrades the performance of the CES unit.
