ASSESSMENT OF FORECASTED ENERGY SUBSTITUTION OF BUILDINGS USING SOLAR HEAT AND COLD
The possibility of using solar energy for heat and cold supply of buildings in the climatic zone of the Central Black Earth region is considered. The main principles of engineering calculation of active systems for utilization of solar radiation for heating premises during the cold season and their cooling in the summer season are given. The results of calculations for the average monthly values of the daily heat consumption of the building allowed us to compare the replacement rates of traditional power supply for two possible design solutions. The first version of the solar system involves the disposal of solar radiation only for heating purposes, and the second - for cooling in the warm season and the subsequent use of an array of radiation-absorbing panels in the heating season. The calculated value of the energy substitution during the installation of an array of collectors with different total area, picked up the required number of solar collectors, justified the choice of the type of the used collectors. The calculations revealed that the additional costs associated with the arrangement of the absorption chiller and an increase in the number of devices that absorb solar radiation, will eventually provide year-round operation built solar system, but also significantly reduce the consumption of traditional resources.
