Abstract
The invention discloses a backwater control method used for a hot-water project and belongs to the field of hot-water project control. The backwater control method includes acquiring water temperature of a thermal-storage water tank and temperature of a backwater pipe through a temperature sensor respectively; responding the water temperature of the thermal-storage water tank and the temperature of the backwater pipe, and comparing the temperature of the backwater pipe with set backwater temperature; judging whether to start backwater control or stop backwater or perform cyclic backwater or not; starting backwater when the interior temperature of the thermal-storage water tank is higher than the backwater temperature and the temperature of the backwater pipe is lower than the set temperature and stopping backwater until the interior temperature of the backwater pipe is higher than the temperature; and starting backwater by a device according to a set time period when the interior temperature of the thermal-storage water tank is lower than the backwater temperature and the interior temperature of the backwater pipe is lower than the set temperature, and stopping cyclic backwater by the backwater device until the interior temperature of the backwater pipe is higher than the set temperature. By the use of the backwater control method, excessively-low interior temperature of the backwater pipe is overcome, and electricity waste caused by continuous backwater is avoided.
Description
Technical field
The present invention relates to the hot water engineering control field, specifically a kind of backwater control method for hot water engineering is applicable to the control of hot water engineering.
Background technology
Engineering or Domestic water tank are when providing hot water, owing to do not use for a long time, will make water temperature in the feed pipe cross low and can't use, when the user need to use, just must first the cold water in the feed pipe be emitted, just can obtain suitable hot water, this has just caused waste, backwater is exactly the cold water in the feed pipe to be sent back in the water tank reheat, thereby has realized the re-using to the feed pipe inner cold water.
At present, employed return water mode mainly is divided into lasting backwater and temperature backwater on the market.Lasting backwater is exactly that the water in the return pipe is continued to send back in the water tank, so will consume a large amount of electricity, and hot water has reduced the speed of heating water tanks in the exchange that will produce with the external world heat when the return pipe.For the general control mode of temperature control backwater be: when the temperature in the return pipe is lower than return water temperature, begin backwater; When temperature is higher than return water temperature in the return pipe, then stop backwater, although this has solved the waste that lasting backwater causes, but when water tank temperature does not also reach return water temperature, water temperature in the return pipe also will inevitably be lower than return water temperature, like this device remains the state that is in backwater always but does not reach required return water temperature, so still there is the phenomenon of waste electricity, and can accelerates the thermal loss of water tank.
Summary of the invention
In order to overcome the deficiency of above-mentioned existing water return method, the invention provides a kind of backwater control method for hot water engineering, can in the lower situation of water tank temperature, both avoid continuing too much power consumption and the thermal loss that backwater brings, and can keep again the water temperature in the feed pipe to be unlikely to low.
The present invention realizes with following technical scheme: a kind of backwater control method for hot water engineering, measure respectively heat storage water tank temperature and return pipe temperature by two temperature sensors, by a water recovery apparatus cold water in the water pipe is drawn back heat storage water tank and cover hot water in return pipe; Concrete control step is as follows:
Gather respectively the temperature of water temperature and return pipe in the heat storage water tank by temperature sensor;
Respond the temperature of water temperature and return pipe in the described heat storage water tank and compare with the return water temperature of setting;
Judge whether to open backwater control or stop backwater or the cycle of carrying out backwater;
Open backwater when water storage the temperature inside the box is higher than when return water temperature, return pipe temperature are lower than the temperature of setting, until the return pipe temperature is higher than this temperature, device stops backwater;
When water storage the temperature inside the box is lower than return water temperature, when the return pipe temperature is lower than the temperature of setting, installs beginning and start backwater according to the setting-up time cycle, until the return pipe temperature is higher than this temperature, water recovery apparatus dwelling period backwater.
The invention has the beneficial effects as follows: not only solved the excessively low problem of temperature in the return pipe, also avoided causing because continuing backwater the phenomenon of waste electricity; Again so that return pipe in temperature use near the user.
Description of drawings
The present invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is workflow diagram of the present invention;
Fig. 2 is embodiment of the invention structural drawing.
Among the figure: 1, heat storage water tank, 2, running water pipe, 3, return pipe, 4, supercharge pump, 5, feed pipe, 6, the backwater solenoid valve, 7, the return pipe temperature sensor, 8, the heat storage water tank temperature sensor.
Embodiment
Embodiment as shown in Figure 2, hot water engineering comprise heat storage water tank 1, and running water pipe 2 is arranged at heat storage water tank 1 top, and return pipe 3 is arranged at heat storage water tank 1 bottom, the double rising pipe of doing.One heat storage water tank temperature sensor 8 is installed in heat storage water tank 1, is used for gathering the water temperature of heat storage water tank 1; One return pipe temperature sensor 7 is installed in return pipe 3, is used for gathering the return pipe temperature; The present embodiment water recovery apparatus comprises a backwater solenoid valve 6 and supercharge pump 4, by water recovery apparatus the cold water in the return pipe is drawn back heat storage water tank 1, covers hot water; The current that backwater solenoid valve 6 and return pipe 3 are used in the control water pipe return heat storage water tank 1; Heat storage water tank 1 is used for storing the hot water of preparation; Supercharge pump 4 and feed pipe 5 are used for delivery to the water terminal.
Workflow diagram as shown in Figure 1, the backwater control of controller can be arranged to continue backwater and carry out backwater according to temperature.When the heat storage water tank temperature was higher than return water temperature, if this moment, the return pipe temperature was lower than uniform temperature, water recovery apparatus began backwater, until the return pipe temperature when being higher than this temperature, just stops backwater; When the heat storage water tank temperature is lower than return water temperature, if this moment return pipe temperature when being lower than design temperature, water recovery apparatus carries out the cycle backwater, until return pipe temperature dwelling period backwater just when being higher than this temperature.By control of the present invention, so that the temperature in the return pipe was unlikely to low, also avoided the wasting of resources that causes because continuing backwater.
