A hot water control and management system
The invention is described in the following statement:-
A hot water control and management system
The invention relates to the field of hot water supply control, in particular to a hot water
control and management system.
The steam boiler hot water system is widely used as a mature technology. The steam
boiler is such a thermal equipment that uses and transfers the heat released after fuel
combustion or the waste heat from industrial production to the water to make the water
reach the required temperature or steam at a certain pressure. After the water enters the
boiler, the heating surface of the boiler transfers the absorbed heat to the water in the
steam-water system. And then the water is heated to hot water with a certain temperature
and pressure or is heated to generate steam, which is then led out for application.
However, with the updating of Heating Ventilation and Air Conditioning (HVAC)
equipment technology, the air source heat pump water heater, as a new type of hot water
equipment, has an increasing market share, and its hot water production efficiency is 3 to
4 times that of conventional steam boilers. Therefore, it is widely used in existing
building energy-saving renovation.
Although the existing steam boiler can ensure the safety of hot water supply, it has the
following shortcomings: 1. The steam boiler system has low efficiency and high energy
consumption. And there is still a lack of efficient energy consumption monitoring
platform. 2. Boiler water treatment is required which increases the cost of water
treatment. 3. Pollution discharge and smoke exhaust of steam boiler pollute the environment. 4. The current hot water control management is characterized by a large number of monitoring points, scattered distribution, and wide area, which are generally installed on the floor. At present, manual inspections are commonly used. On the one hand, manpower is wasted. The hot water supply manager inspects the temperature and water level of all hot water supply tanks more than 5 times a day; on the other hand, it is difficult for operators to find hidden dangers of accidents.
The purpose of the present invention is to solve the above-mentioned technical problems.
The present invention proposes a hot water control and management system to solve the
problem of low system efficiency and high energy consumption wasting electric energy
when using a steam boiler hot water system in the prior art to supply water, and the
problem that existing hot water control and management wastes manpower and there is a
potential accidents.
The technical solution adopted by the present invention to solve the above technical
problems is a hot water control and management system, including a water supply system
and a monitoring system. The water supply system is connected between the water supply
tank and the hot water concentrator, which includes an air source heat pump water heater
unit, which is connected to a water supply tank through a first water pump and is used to

Optimization controller respectively connects with the air source heat pump water heater unit and the heat preservation water tank, which is used to control the operation of the air source heat pump water heater unit according to the temperature, liquid level and time-of-use electricity price of the water in the heat preservation water tank.

water concentrator to collect data in real time and transmit it to the data transmission
system; the data transmission system is to send the received data to the storage; the
storage is used to store the data sent by the data transmission system; the monitoring
terminal is used to download the real-time and historical data of the storage and perform
energy consumption monitoring. After the data acquisition system initializes the data, the
data acquisition channel is set up, the same information data collected by the data
acquisition system is averaged, and then sent to the storage to store the data. The storage
transmits the stored data to the monitoring terminal. Storage includes cloud storage and
storage device storage. Several data acquisition systems are connected to several hot water concentrators, and several data acquisition systems transmit the collected information to the storage through the data transmission system.

water and then transmits it to the heat preservation water tank.

ultrasonic flowmeter, a pressure sensor, and an electric meter. The ultrasonic flowmeter is

pump in the hot water concentrator in real time; the electric meter is used to obtain the
instantaneous power of the fourth water pump unit; the data acquisition instrument is

through the first water pump, and the air source heat pump water heater unit heats the
water and sends it to the heat preservation water tank. The heat preservation water tank

raise the liquid level to the lowest liquid level VL, and if the actual liquid level V is

TL and less than the standard water supply temperature TZ, judge whether the actual
liquid level V is greater than or equal to the maximum liquid level VH.
If the actual liquid level V is greater than or equal to the maximum liquid level VH,
heating is carried out in a circulation mode to increase the temperature to the standard
water supply temperature TZ. If the actual liquid level V is less than the maximum liquid
level VH, the direct heating mode is used to raise the liquid level to the maximum liquid
level VH. If the actual temperature T is less than the minimum water supply temperature
TL, judge whether the actual liquid level V is greater than or equal to the maximum
liquid level VH. If the actual liquid level V is greater than or equal to the maximum
liquid level VH, the circulation mode is used to increase the temperature to the standard
water supply temperature TZ. If the actual liquid level V is less than the maximum liquid
level VH, the direct heating mode is used to increase the liquid level to the maximum
liquid level VH , and the temperature is rised to the standard water supply temperature
TZ. If the time-of-use electricity price at this time is not in the valley period, continue to
judge the time-of-use electricity price;
3) Judge whether the time-of-use electricity price at this time is a flat time period. If the
time-of-use electricity price at this time is a flat time period, determine whether the actual
temperature T is less than the minimum water supply temperature TL. If the actual
temperature T is less than the minimum water supply temperature TL, the temperature is
raised to the minimum water supply temperature TL in the circulation mode. If the actual
temperature T is greater than or equal to the minimum water supply temperature TL,
determine whether the actual temperature T is less than the standard water supply temperature TZ. If the actual temperature T is less than the standard water supply temperature TZ, judge whether the actual liquid level V is less than the intermediate liquid level VM. If the actual liquid level V is less than the intermediate liquid level VM, the direct heating mode is used to raise the liquid level to the intermediate liquid level
VM. If the actual liquid level V is greater than or equal to the intermediate liquid level
VM, it will enter the standby mode. If the actual temperature T is greater than or equal to
the standard water supply temperature TZ, it will enter the standby mode. If the time-of
use electricity price at this time is not the normal period, the time-of-use electricity price
is determined as the peak period.
4) If the time-of-use electricity price at this time is the peak period, judge whether the
actual temperature T is less than the minimum water supply temperature TL. If the actual
temperature T is less than the minimum water supply temperature TL, the temperature is
raised to the minimum water supply temperature TL in the circulation mode, and if the
actual temperature T is greater than or equal to the minimum water supply temperature
TL, it enters standby;
