Regional distributed hot water sharing system and control method

Abstract

The invention discloses a regional distributed hot water sharing system and a control method. The regional distributed hot water sharing system mainly comprises a solar heat collector, a solar user water tank, other energy user hot water pipes, a sharing water tank, a water supply main pipe, a water return main pipe, a remote water meter, a liquid level sensor, a temperature sensor, matched pumps,valves and pipelines, wherein the solar heat collector provides hot water for the solar user water tank; the solar user water tank is connected with a water supply and return main pipe; the remote water meter is used for metering hot water flow; the liquid level sensor is used for measuring the liquid level of the water tank; the temperature sensor is used for measuring the temperature of the water tank; and the pump, the valve and the pipeline are used for forming a heat energy sharing network. The regional distributed hot water sharing system is applied to a single multi-storey building ora low-storey building community. The users utilize solar water tank hot water, and two-way conveying of hot water between the users and the shared water tanks is achieved through the water supply header pipe and the water return header pipe, and the users in each area share one shared water tank and the same pair of header pipes, and the shared water tanks in the adjacent areas are connected, anda community hot water network is constructed, and the hot water supply and demand side imbalance problem is relieved in a sharing mode.

Description

technical field [0001] The invention belongs to the field of solar heating engineering, and relates to a regional distributed hot water sharing system and a control method. Background technique [0002] The current distributed heating system can use gas, electricity, solar energy, etc. to provide energy to meet the family's own heat demand. However, there is still a mismatch between the supply and demand of ordinary solar energy, gas, electricity and other energy hot water supply systems and household hot water consumption in terms of time and quantity, resulting in surplus heating for solar energy users, while other energy users still need to consume electric energy Or gas meets the demand for hot water, resulting in waste of energy and low utilization rate of renewable energy. Therefore, it is necessary to solve these problems based on the design of the thermal energy sharing network and through the dispatching and control of hot water information.
