Description

System and method for supplying warm boiled water to multiple terminals

technical field

The present invention relates to a system and a method for supplying warm boiled water, in particular to a system and a method suitable for centralized supply of warm boiled water to multiple terminals in residences and office buildings.

Background technique

At present, there are systems for supplying warm boiled water to residential buildings and office buildings, and most of them can supply warm boiled water to multiple terminals for personnel to directly fetch water for reference. However, the control of the water temperature is not flexible enough and not accurate enough. Usually, the heating source is directly controlled to reach the required temperature. When the water temperature is low, users often need to mix raw water with hot water to make it reach the required water temperature; this makes it inconvenient for users to use, and adding raw water to drink is not good for health and cannot reach the user's use need.

Contents of the invention

The purpose of the present invention is to solve the above-mentioned problems existing in the prior art, and propose a system and method for supplying warm water to multiple terminals.

A further optimization scheme of the system for supplying warm boiled water is to further include a control cabinet, the control cabinet is equipped with a PLC, the electromagnetic heater, the first valve, the second valve, the third valve, the temperature sensor, the auxiliary heating The controller, water level sensor, return pump, water pipe booster pump and water quality monitor are all electrically connected to the PLC; the control cabinet is also provided with an operation interface.

The present invention also proposes a method for supplying warm boiled water to multiple terminals, which uses the above-mentioned system for supplying warm boiled water to multiple terminals to supply warm boiled water, which includes the following steps:

S1, input preset water temperature, preset water volume, preset time point and running time on the operation interface;

S2, when the preset time point is reached, perform the water storage operation of opening the first valve, so that the municipal tap water is heated by the electromagnetic heater for a running time to become boiled water, and after being turned into warm boiled water by the heat exchanger, it is supplied to the water storage tank;

S3, the water level in the water storage tank reaches 4/5, when the water temperature is at the preset temperature, the water storage operation is continued; when the water temperature is lower than the preset temperature, the second valve is opened, the first valve is closed, and the electromagnetic heating The boiled water heated by the device is directly supplied to the water storage tank for warming operation until the water temperature reaches the preset temperature and the water level reaches the preset water volume;

S4, supplying the warm boiled water in the water storage tank to multiple terminals.

A further optimized solution of the method for supplying warm boiled water is that in step S2, when the water level of the water storage tank reaches 2/3, the operation of opening the third valve and the return pump is performed.

A further optimization scheme of the method for supplying warm boiled water is that in step S4, when the temperature sensor of the terminal senses that the water temperature is lower than a preset temperature, the auxiliary heater heats and supplements the warm boiled water at the terminal.
