A regional distributed hot water sharing system and control method

Abstract

A regional distributed hot water sharing system and control method, mainly composed of solar collectors, solar user water tanks, hot water pipes for other energy users, shared water tanks, water supply main pipes, return water main pipes, remote water meters, liquid level sensors, temperature Sensors and supporting pumps, valves and pipelines. The solar heat collector provides hot water for the solar user water tank, the solar user water tank is connected to the water supply and return water mains, the remote water meter measures the flow of hot water, the liquid level sensor measures the liquid level of the water tank, and the temperature sensor The tank temperature is measured and the pumps, valves and pipes are used to form a heat sharing network. The present invention is applied in a single multi-storey building or a low-rise building community. The user utilizes the hot water of the solar water tank to realize two-way transportation of hot water between the user and the shared water tank through the water supply and return water main pipes. Users in each area share a shared water tank and the same For the main pipe, the shared water tanks in adjacent areas are connected to each other to build a community hot water network to alleviate the imbalance between hot water supply and demand in a shared 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.
