Combined cooling and heating with energy storage solar thermal energy utilization system and application method

Abstract

The invention provides a solar thermal energy utilization system with energy storage combined cooling and heating and a using method, wherein, the outlet of the heat transfer medium of the concentrating heat collector (1) respectively passes through the first regulating valve (5), the second The regulating valve (6) is connected to the energy storage system (2), the heating system (3), and the refrigeration system (15) through pipelines. The energy storage system (2) includes an energy storage tank (201), and the energy storage tank (201) is provided with an energy storage tank inlet (202) and an energy storage tank outlet (203); the energy storage tank (201) is filled with energy balls (203); wherein, the energy ball (203) includes a steel spherical shell, and the steel spherical shell is filled with molten salt. The invention absorbs solar energy to heat up during the day, and excess solar thermal energy can be stored in an energy storage system, thereby achieving an all-weather heating mode.
