Abstract

The invention provides a solar heat supply system based on cross-seasonal water body heat storage. The solar heat supply system mainly comprises a solar heat-collecting system, a cross-seasonal heat storage water body, a heat pump, a buffer water tank, a heat user, an auxiliary heat source, a heat exchanger and a control system. The solar heat-collecting system communicates with the cross-seasonal heat storage water body. The cross-seasonal heat storage water body is connected with the heat exchanger. The heat exchanger directly communicates with the buffer water tank or is connected with the buffer water tank through the heat pump. The buffer water tank communicates with the heat user. The solar heat supply system is further provided with the auxiliary heat source which is directly connected with the buffer water tank. The solar heat supply system based on cross-seasonal water body heat storage 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 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 realize the 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 urban residential buildings, due to the small building shape coefficient and the small area of the building body for placing solar collectors, it is impossible to realize solar building integration like a single building in a village or town. According to relevant research, concentrated solar heating system is one of the low-carbon heating systems more suitable for urban buildings. The concentrated solar heating system inc...
