Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] like figure 1 As shown, the solar heating system based on interseasonal water heat storage in the present invention mainly includes: solar heat collection system 1, buffer water tank 2, interseasonal hot water storage body 3, absorption heat pump 4, heat user 5, auxiliary heat source 6, Heat exchangers E-1, E-2, and control system 8.

[0037]The solar heat collection system 1 communicates with the buffer water tank through a pipeline with a first valve V-1 and a first water pump P-1. The buffer water tank 2 communicates with the cross-season hot water storage body 3 through a pipeline with a second heat exchanger E-2. The buffer water tank is connected to the second heat exchanger E-2 through the pipeline with the second valve V-2 and the second water pump P-2, and the inter-seasonal hot water storage body 3 is connected to the second ...

Abstract

A solar medium-temperature heating system based on interseasonal water heat storage, including: solar heat collection system, interseasonal water storage body, absorption heat pump, buffer water tank, heat user, auxiliary heat source, water pump, valve, heat exchanger, Control System. The solar heat collection system is connected with the buffer water tank, and the interseasonal hot water storage body is connected with the heat users and the absorption heat pump through the heat exchanger. The auxiliary heat source communicates with the absorption heat pump and heat users. Through the adjustment of different modes, the present invention can realize the multi-energy complementary heat supply of solar energy and other energy sources, and can meet the hot water temperature requirements of general urban pipe networks. The invention is suitable for building heat supply in urban areas with abundant solar energy resources in northern my country.

Description

technical field [0001] The invention relates to a solar 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 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...
