Brand-new temperature stratified water tank for cold and heat combined supply energy storage system

Abstract

The invention discloses a brand new temperature stratified water tank for a cold and heat combined supply energy storage system, and particularly relates to the technical field of stratified water tanks, the brand new temperature stratified water tank comprises a water tank, a first oil laminating tank is mounted in the water tank, and an energy storage mechanism is mounted below the first oil laminating tank; the energy storage mechanism comprises a fourth oil laminating box arranged below the first oil laminating box, a second oil laminating box is installed below the fourth oil laminating box, and a third oil laminating box is installed below the second oil laminating box. According to the water heater, alternate heat exchange operation is achieved during heat exchange, alternate heat exchange is conducted from top to bottom and in the middle, the heating efficiency of water is greatly improved, the effect of high-speed heat exchange can be achieved even if circulating water with high flowability is used, the heat exchange efficiency is higher and more uniform, storage is continuous, and heat energy waste is not likely to be caused.

Description

technical field [0001] The invention relates to the technical field of stratified water tanks, more specifically, the invention relates to a brand-new temperature stratified water tank based on combined cooling and heating energy storage systems. Background technique [0002] In the construction of the power network, the "source-network-load-storage" comprehensive smart energy system with scattered physical space, integrating power-side energy storage devices, load-side energy storage devices, and electric-heat and electric-cold coupling conversion elements System, in the combined cooling and heating function source system, it is necessary to use stratified water tanks to store the temperature inside the hot water tank, which requires the use of temperature stratified water tanks for energy storage. [0003] In actual use, it is necessary to heat the inside of the stratified water tank, so that the circulating water inside the water tank can be heated, and then the heated wa...

AI Technical Summary

Problems solved by technology

[0004] During the heating process, due to the high fluidity of the injected circulating water, the colder external water cannot be heated quickly and evenly after entering the water tank. At the same time, during the heating process, the heating temperature of the water can only reach Certain stability, so that the stored heat is small, so that in the heat exchange process of circulating water, it is impossible to store higher heat energy, the storage effect is poor, and the heat transfer uniformity is poor
