More frequent and promptly thermal energy storage tank charging/discharging cycles. For refrigeration systems characterized by peak-valley load variations, integrating a small-scale thermal energy storage tank to deal with these fluctuations can achieve low investment and high energy savings.
However, in some application scenarios, such as the combined heat and power (CHP) plants and solar heating for civil architecture and industrial application, the single-tank thermal energy storage system based on water is commonly employed because of its low cost and no solidification in a large range of temperature.
Compared with two-tanks, a single-tank thermal energy storage system has the prominent potential of saving the investment in the first hardware and infrastructure. Obviously, the thermocline thickness is a significant parameter for evaluating the heat performance of the single-tank TES system.
Moreover, during the discharging HTF is pumped into the heat exchanger to heat transfer to the working fluid and flows into a low temperature tank. This is the working procedure of the two-tank TES system. Up to now, a single-tank thermal energy storage system is becoming a novel TES.
