Henger Nuan Automation Center, two water heaters complement each other and intelligent water supply control device
Pros and cons of solar heating water
Everyone knows, solar water heaterbecauseUtilizedtooSunlightfreeMake hot water,veryEnergy-saving water heater,soIt is widely used.But it also has onemajorThe lack ofpoint,,thisthat is:If continuousSolar water heaters will not be able to use without sunshine or insufficient sunshine for a few days.For the convenience of life,a lot ofAnother familyExternal installationA other water heater, such as: gas water heater (including gas wall-mounted furnace, the same below) or electric water heater, when the solar water heater cannot be used, turn onThis one supplementsWater heater, usually when solar water heater can be used,,Just closeThis oneWater heater, this is energy-saving and does not affect use.
However, these two energy water heatersCooperateWhen supplying hot waterVery inconvenient, in use one of themtowerWhen the water heater is supplied with hot water, turn off the other one manually.towerWater heater is troublesome to operate, especially when the switches and valve installation positions of the two energy water heaters are far apart.It's even moreinconvenient.
Overview of the Autonomous Control Center
Two types of energy water heaters combined with complementary hot water supplyintelligent controlDevice
In order to solve the above-mentioned problems, Hefei Hengnuan HVAC Equipment Co., Ltd.Invented“Solar+Fast water heater automatic control center”.The automatic control device canWhen users use hot water, according to the comparison between the set water temperature and the actual water temperature,intelligentSwitchSolar water heater andFastWater heater(Gas water heater, gas wall-mounted furnaceor即 式 式 式 式 式wait), in solar water heaterGet out of the waterWhen the water temperature can reach the set temperature, the fast water heater is not turned on, and when the solar energy isWater outlet temperatureWhen the set temperature is not reached, the fast water heater will be automatically turned on, and the solar energy will be heated.waterDeviceFlow outThe water is then reheated through a quick water heaterEssenceThis is both energy-saving and very convenient, and there is no need for manual operation.
ShouldThe automatic control center is composed of electric three-way valve, temperature sensor, temperature controller and copper pipe connected toAs well asPipelineHousingThe temperature sensor is directly inserted into the water to make the measured temperature more accurate. The temperature controller has a larger LCD screen, which can display the set temperature, actual temperature, working mode, date and time, etc.The automatic control center has manual mode and timing automatic mode. The manual mode is defaulted to manual mode throughbutton“▲”set upIncreaseTemperature, by pressing the button“▼”set upreduceTemperature is very easy to operate; the timing automatic mode can be divided into four time periods every day, and different water temperatures can be set for each time. After the mode is set, the thermostat will turn on and off regularly according to the set time, which not only saves energy and is convenient to improve life comfort, but also extends the service life of the automatic control center.

These two kinds of water heaters are combined with water heating automatic control devices. One is a water heater as a common water heater and the other is a supplementary water heater. Generally, commonly used water heaters are very energy-saving water heaters. For example, solar water heaters, air-energy water heaters that can be heated at peak and valley electricity prices are generally volume water heaters. The supplementary water heater is turned on urgently when the water volume of common water heaters is insufficient or the temperature is insufficient. It is an infrequently used water heater, but it can be heated quickly when needed. Therefore, replenishing water heaters generally require quick water heaters, such as: gas water heaters, gas wall-mounted boilers or electric fast water heaters.

The automatic control center has hot water circulation function
Compared with traditional water heater circulators, it reduces the frequent start of the water heater and extends the service life of the water heater.
The controller of the automatic control center has a hot water circulation pump terminal, which can be connected to an external hot water circulation pump. In this way, the automatic control center can control the hot water circulation pump at the same time, which can enable the hot water circulation to be opened at a fixed temperature, so that each water point will open and there will be hot water immediately, and will not waste cold water, reduce waiting time, which is convenient, comfortable and energy-saving.
In this hot water system, the solar water tank or air energy tank becomes the water storage buffer tank.When the water outlet temperature of the water tank is higher than or equal to the set water temperature, the water flow will not pass through the replenishing water heater and flow directly to the water point. In this way, the replenishing water heater will not start. Only when the water outlet temperature of the water tank is lower than the set water temperature, the water flow will be reheated through the replenishing water heater and then to the water point..Compared with the water heater circulator (pump) commonly sold on the market, as soon as the machine is turned on, the hot water must flow through the water heater and turn on the water heater simultaneously. This greatly reduces the frequency of starting and stopping of the water heater and greatly extends the service life of the water heater.

When used as a hot water circulator, it also has the intelligent control function of the timing and temperature of the automatic control center.
When used as a hot water circulator, the machine can be turned on and off at a regular time, and the hot water cycle can be automatically turned on when hot water is not needed. This not only achieves efficient energy saving, but also improves water comfort, and extends the service life of the automatic control center and circulation pump.
The automatic control center also hasLow temperature anti-freezing function.
In hot water systemDesigned as a hot water circulation systemUnder the premise of the hot water system (the hot water system is made into a loop and the automatic control center is equipped with a hot water circulation pump)When the water level is lower than5At ℃, the automatic control center automatically turns on the low temperature protection function. At this time, the three-way valve and water pump are turned on as needed; when the water temperature reaches15After ℃, the valve and water pump are closed, thereby ensuring that the home hot water system will not be frozen due to freezing.Note: To ensure that this function works, it is necessary to ensure that the power and gas of the gas or electric water heater are connected., can be normal

The automatic control center also hasSelf -protection function
When the automatic control center stops working24When no more work is done within the hour, the three-way valve and circulation pump will work automatically.40s, to prevent the three-way valve or circulation pump from sticking and locking.
This solar energy+The invention of the fast water heater automatic control center allows users to enjoy free solar hot water, and intelligently switch to secondary heating when the water temperature is not enough. It also has hot water circulation function, anti-freeze function and anti-lock function, intelligent timing and temperature control, and greatly extend the service life of the fast water heater. It is a very good invention.
