Determination of the energy efficiency of a flat reflector solar air heating collector with a heat accumulator

The article presents an improved scheme and pilot-industrial copy of a flat reflector solar air heating collector with a heat accumulator. The heat balance equation of the flat reflector solar air heating collector with heat accumulator is constructed, and its energy efficiency is based on it. Considering the local climatic and meteorological characteristics of the city of Karshi, its useful performance coefficient was determined based on the experiment conducted on the flat reflector solar air heating collector with a heat accumulator. This designed device is proposed as an active solar heating system for the anaerobic digestion of municipal solid waste based on energy and resource efficiency. As a result of experimental studies, a flat reflector solar air heating collector with a heat accumulator’s high energy efficiency was determined in the heating heat carriers (air up to + 75°C and heat accumulators up to +85°C) on February 24, 2023
