Using of Evacuated Solar Tube Collectors for Heating in Central Yakutia Conditions

Abstract

In the Department of Energy Problems of the IPTPN SB RAS an experimental stand for a solar heat supply system based on the evacuated solar tube collector was assembled. During the experiment the incident solar radiation on the collector surface and the corresponding thermal energy received from the evacuated solar tube collector were measured. Data collection began at the end of 2021 and is still ongoing. The obtained experimental data will allow to study the efficiency of the evacuated solar tube collectors in the climatic and natural conditions of Yakutsk (Central Yakutia) and measure the intensity of solar radiation. The obtained research results will make it possible to determine the effectiveness of using solar heating systems based on evacuated solar tube collectors in the conditions of Yakutia, as well as their feasibility. Features of the solar heating system operation in extremely low temperatures have been identified. Recommendations to take these features into account are given. Based on the data received the database of the solar heating system operation and the database of solar insolation were developed and registered.
