Heat supply system for coupling application of geothermal energy and solar energy and working method thereof

Abstract

The invention discloses a heat supply system for coupling application of geothermal energy and solar energy and a working method thereof. The heat supply system comprises a solar heat collector, a first separation type heat pipe, a second separation type heat pipe, a heat storage tank, a first heat exchange pipe and a geothermal energy system. A heat user is provided with the heat storage tank and the first heat exchange pipe; the hot end of the first heat exchange pipe is connected with the heat storage tank, the cold end of the first heat exchange pipe is arranged in the heat user, and a circulating pump is arranged on the first heat exchange pipe; the hot end of the first separation type heat pipe is connected with the solar heat collector, the cold end of the first separation type heat pipe is connected with the heat storage tank, the hot end of the second separation type heat pipe is connected with the geothermal energy system, and the cold end of the second separation type heat pipe is connected with the heat storage tank. The geothermal energy and solar energy can be efficiently extracted and transmitted in an energy-saving mode, and the problem that renewable energy sources cannot meet the requirements of heat users due to insufficient heat is solved.

Description

technical field [0001] The invention belongs to the technical field of heat supply, and in particular relates to a heat supply system and a working method thereof for coupled application of geothermal energy and solar energy. Background technique [0002] With the proposal of the "double carbon" target, the application of new energy is becoming more and more common. Heating is the foundation of people's livelihood, and the annual energy consumption for heating accounts for a large proportion. Therefore, the promotion of renewable energy heating is the general trend. Using renewable energy for heating can greatly reduce the use of traditional fossil fuels, thereby reducing carbon emissions. However, a single renewable energy source may not be able to meet the needs of heat users due to insufficient heat. Therefore, two or more renewable energy sources need to be coupled to ensure the quality of heat supply. The extraction of multiple energy sources will increase the power ...
