INCREASING ENERGY EFFICIENCY IN SOLAR HEAT SUPPLY SYSTEMS BASED ON HEAT ACCUMULATION AND SELF-CONTROLLED HYDRAULIC PROCESSES

This article studies the integration of thermal storage (TES) and self-regulating thermal-hydraulic processes in improving the efficiency of solar thermal systems. The main objective of the study is to increase energy efficiency by reducing temperature potential losses during heat transfer from the solar collector to the heat accumulator and from it to the consumer. Experimental studies were carried out on a pilot plant based on a flat-plate solar collector. The results showed that there is a direct relationship between solar radiation, collector outlet temperature and heat accumulator temperature. The average efficiency of the system was found to be in the range of 45–60%. When using a heat accumulator system, an increase in energy efficiency by 20–35% was observed. Self-regulating hydraulic elements served to stabilize the flow and reduce heat losses.
