The concept of a seismically isolated building with solar heating system (SHS) with air solar collectors (ASC) and the seasonal heat storage (LTS), situated under the house has been proposed. Houses with solar heating system with different heat consumption have been examined: 21.15, 9.35 and 3.75 MWh. Influence of the main design and operational parameters on energy and economic indicators of the SHS have been investigated. Solar share of the building’s heating ranged between 0.2-1. Two types of ASC have been considered: with selective and non-selective matrix absorber. LTS parameters were calculated for the variant without any heat exchanger with the use of plastic containers with water. Maximum water temperature inside LTS was varied in the range 55-95° C. Minimum cost of solar thermal energy is achieved with a solar fraction equal to 1, and it is approximately two times lower than using natural gas. We also consider the effectiveness of seismic impact on the house through the use of the LTS as a massive foundation of the house and its flexible insulation for seismic isolation of the house in case of earthquakes. It’s shown the possibility of reducing the intensity of exposure up to 2-3 points on the MSK-64 scale. This will make the superstructure of the house lighter and less expensive, which further improves the economical indicators of the project. |
