Introduction to thermal energy storage systems
Thermal energy storage (TES) systems can store heat or cold to be used later, at different temperature, place, or power. The main use of TES is to overcome the mismatch between energy generation and energy use (Mehling and Cabeza, 2008, Dincer and Rosen, 2002, Cabeza, 2012, Alva et al., 2018).The mismatch can be in time, …
Heat exchanger
Heat exchangers are systems that use a fluid to absorb heat from a hotter outside source without the fluid and hot source mixing together. Therefore, the fluid that entered hot, leaves cold and the initially cold fluid leaves hot. For example, water can be heated while inside a metal pipe within a furnace or boiler.There could ways to heat water (and cool a heat …
