A water heater that adjusts its temperature based on solar energy

Abstract

The calculation method for a water distributor of a constant cross section uniformly perforated along the height for a multilayer stratified thermal storage tank used in solar heating and hot water supply systems was developed. The advantages of using self-regulating stratification water heat accumulators in solar heat supply systems are considered. It is shown that the use of stratification for short-term and long-term thermal accumulation leads to an increase in the use of solar heat by 15-20% compared to batteries with completely mixing water. In hot water systems, these batteries can provide earlier preparation of hot water with the required temperature for consumers. Based on the analysis of world experience in the development of water heat accumulator designs using temperature stratified water and the stability of the stratified flow of coolant in the accumulator volume, a new, self-regulating, water accumulator design has been proposed.
