Solar medium-temperature heat supply system based on cross-seasonal water body heat storage

Abstract

The invention provides a solar medium-temperature heat supply system based on cross-seasonal water body heat storage. The solar medium-temperature heat supply system comprises a solar heat-collecting system, a cross-seasonal heat storage water body, an absorption heat pump, a buffer water tank, a heat user, an auxiliary heat source, water pumps, valves, heat exchangers and a control system. The solar heat-collecting system communicates with the buffer water tank. The cross-seasonal heat storage water body communicates with the heat user and the absorption heat pump through the heat exchangers. The auxiliary heat source communicates with the absorption heat pump and the heat user. According to the solar medium-temperature heat supply system based on cross-seasonal water body heat storage, multi-energy complementary heat supplying can be achieved through solar energy and other energy sources by adjusting different modes; and the requirements for the heat supply water temperature of general city pipe networks can be met; and the solar medium-temperature heat supply system is suitable for supplying heat to buildings in northern China urban areas where solar energy resources are rich and relatively rich.

Description

Technical field [0001] The invention relates to a solar energy medium temperature heating system. Background technique [0002] Solar energy is an inexhaustible renewable energy source. Today, as fossil fuels are decreasing year by year and the international energy situation is becoming increasingly severe, the development and utilization of solar energy is one of the important ways to achieve diversification of energy supply and ensure energy security. Solar heating is one of the effective ways to reduce the heating coal consumption of buildings in northern my country. For residential buildings in cities and towns, due to the small form factor of the building, the area where the solar collector is placed on the building body is small, and it is impossible to realize the integration of solar energy buildings like single buildings in villages and towns. According to related research, the centralized solar heating system is one of the low-carbon heating systems more suitable for u...
