Thermal Energy Storage

1 Introduction. Thermal energy storage (TES) is the term used to describe the capture and storage of thermal energy for later use. The stored thermal energy may be used for heating or cooling applications. Of most significance, TES is useful for addressing the mismatch between the supply and demand of energy [1].

Absorption Cooling

To facilitate absorption cooling, a working pair of an absorbent and a refrigerant are required. Common working pairs include lithium bromide/water and ammonia/water ( Ziegler, 1999 ). A standard absorption cooling cycle involves four major stages ( Figure 1.5 ). These stages include the generator where the driving heat is input to volatilize ...

Uses of sands in solar thermal technologies
