Detailed Description
The principles and spirit of the present invention will be described with reference to a number of exemplary embodiments shown in the drawings. It should be understood that these embodiments are described only to enable those skilled in the art to better understand and to implement the present invention, and are not intended to limit the scope of the present invention in any way.
Referring to fig. 1, an energy storage device according to an embodiment of the present invention includes a boiler 110, a water container 120, a water mixing system 130, and related pipes and valves. The boiler 110 has a boiler water outlet 111 and a boiler water return port 112. The hot water output from the boiler outlet 111 of the boiler 110 is first delivered to the water storage container, and then output to an external system, such as a heat supply pipe network, through the water mixing system 130. The return water returned from the external system passes through the water storage container 120 again, is delivered to the boiler return water port 112, and is returned to the boiler 110.
The water storage container is used for storing hot water from the boiler, receiving cold water returned from an external system and playing roles in storage and transfer. The water storage container may be constructed in various forms such as a box shape as shown in fig. 1.
In some embodiments, the boiler water outlet 111 is connected to the first pipe 201, and the end of the first pipe 201 is connected to the water storage inlet 121 of the water storage 120, for example, may be connected to the upper end of the water storage 120. The water storage container 120 is further provided with a water storage container outlet 122, for example, the water storage container outlet 122 and the water storage container inlet 121 may be arranged at the same height at intervals. The water outlet 122 of the water container is connected to the second pipeline 202, the end of the second pipeline 202 is connected to the water inlet 131 of the water mixing system, and the water is output to the external system through the third pipeline 203 connected to the water outlet 132 of the water mixing system. A first temperature sensing device 401, such as a temperature sensor assembly, may be provided on the third conduit 203 for monitoring the temperature of the output hot water in real time.
When the external system returns water, the water storage container return pipe 301 is connected first, and the downstream side of the water storage container return pipe 301 is connected to the water storage container return port 123 of the water storage container 120. The upstream side of the water storage container return pipe 301 may be higher than the downstream side so that the return water may automatically flow back under the gravitational potential energy. A first branch point 302 is formed on the water storage container return pipe 301, the first branch pipe 204 is connected to the first branch point 302, and the downstream side of the first branch pipe 204 is connected to the water inlet end 131 of the water mixing system 130.
A first control valve 205 (which may be an electric two-way valve) is further installed on the first branch pipe 204, and the first control valve 205 can control the connection and disconnection of the first branch pipe 204. When the first temperature detecting device 401 detects that the output water temperature is too high, the first control valve 205 opens the first branch line 204, at this time, the water returning from the water storage container water return line 301 is branched at the first branch point 302, a part of the water continues to return to the water storage container 120 along the water storage container water return line 301, and another part of the water flows into the mixing system 130 along the first branch line 204. In the water mixing system 130, on one hand, hot water output from the boiler 110 is received, on the other hand, return water from the first branch pipeline 204 is received, and due to the fact that the temperature of the return water is low, after the return water and the hot water are mixed and blended, the overall water temperature is reduced, and therefore the temperature of output water is reduced. Until the desired output water temperature is reached, the energy storage device does not need to introduce return water to reduce the temperature and the first control valve 205 is closed.
In some embodiments, the frequency of switching between on and off of the first control valve 205 may be high. When the first temperature detection device 401 detects that the temperature of the output water is slightly higher than the expected water temperature, the first control valve 205 is immediately opened to deliver the return water, and the temperature of the output water is reduced. Because the difference between the output water temperature and the expected water temperature is small, the backwater can quickly reduce the overall output water temperature to the expected level, and at this time, the first control valve 205 is immediately closed in order to avoid the water temperature from continuously reducing below the expected level. After a short time interval, the output water temperature will reach a level slightly higher than the expected water temperature, and at this time, the first control valve 205 is controlled to open again, and the cycle is repeated, so that the output water temperature can be always kept in a relatively constant state, and the constant state is obtained by adjusting the first control valve 205 frequently in real time.
Sometimes, although the first control valve 205 is kept in a normally open state, the temperature of the output water cannot be reduced to a desired level. The inventor finds that the temperature reduction effect is not obvious enough due to the fact that the water temperature output by the boiler is too high, and the return water branched from the first branch point 302 is only a part of the whole return water. For this purpose, a second diversion point 303 is provided on the water storage container return pipe 301 downstream of the first diversion point 302, and a return water blocking system 140 is provided at the second diversion point 303 for controlling to block all return water.
The return water shutoff system 140 may take a variety of forms, such as valves with various types of passageways, valve blocks, combinations of valves and piping, and the like. For example, in the embodiment shown in FIG. 1, the return water blocking system 140 includes a second control valve 141, and the second control valve 141 is a three-way valve with one inlet and two outlets, and one of the outlets can be opened and the other outlet can be closed by on-off control of the second control valve 141. The inlet of the second control valve 141 is located at the upstream side, one outlet of the downstream side leads to the water storage container 120 along the water storage container return pipeline 301, the other outlet is connected with the second branch pipeline 206, and the downstream side of the second branch pipeline 206 is connected with the water inlet end 131 of the water mixing system. Furthermore, a second temperature detection device 402 is arranged on the line between the second tapping point 303 and the first tapping point 302, which second temperature detection device 402 is used to detect the temperature of the return water.
The second temperature detection device 402 is disposed in the return water blocking system 140, so that whether the return water diverted by the first branch pipeline 204 is enough to reduce the temperature of the output water to a desired level can be determined from the temperature of the return water. This is because the temperature of the hot water output from the boiler 110 is high, and if the temperature of the returned water detected by the second detecting device 402 approaches the threshold temperature of the switch of the first control valve 205 (i.e. the expected output water temperature), it indicates that the temperature of the diverted returned water is not enough to significantly reduce the temperature of the hot water output from the boiler 110.
When the first temperature detecting means 401 detects that the temperature of the outputted water is too high, i.e. higher than the expected temperature t1And the temperature of the backwater detected by the second temperature detecting device 402 is also higher than the preset backwater temperature value t2Then, the second control valve 141 is controlled to close the outlet to the water storage tank 120 and open the outlet to the second branch line 206. At this time, all of the backwater is blocked and no longer flows back into the water storage container 120, but is completely delivered to the mixing system through the first branch pipe 204 and the second branch pipe 206. Therefore, all the backwater is used for reducing the output water temperature, and the output water temperature can be further reduced.
According to the present embodiment, the temperature threshold t is set1And t2Then, t can be2Is slightly less than t1The temperature of (2). If the second temperature detecting device 402 detects that the temperature of the return water is higher than t2At this time, it is stated that the return water temperature is higher, if the return water continues to enter the water storage container 120, the return water is further heated in the water storage container 120 with a very high temperature, and then enters the boiler 110 for circulation, which is more unfavorable for the reduction of the output water temperature, therefore, the second control valve 141 should be controlled to close the return water to the water storage container 120, and open the outlet to the second branch pipeline 206, and at this time, all the recovered return water does not enter the water storage container 120 and the boiler 110 for heating, but directly enters the water mixing system to reduce the water temperature output by the boiler 110, until the output temperature is reduced to t1And the temperature of the return water is reducedTo t2Thereafter, the second control valve 141 is controlled to close the outlet to the second branch line 206 and open the outlet to the water storage container 120, and water is returned again.
Threshold temperature t1And t2Can be flexibly adjusted according to seasonal changes or other heating demands, for example, when the output hot water is used for heating, t can be adjusted in the early winter when the weather is slightly cold1Set at 35 ℃ t2Set to 32 deg.C, and set t to be in cold weather and deep winter1Set at 40 ℃ t2Set at 38 deg.c.

The number of the water inlet ends 131 may be multiple, and depends on the number of pipes to be connected to the upstream side of the water mixing system 130. The number of the water pumps 134 may be provided in plurality for increasing pumping efficiency. In other embodiments, a container such as a water tank may be used instead of the mixing pipe 133.
In some embodiments, a first branch point 207 is configured on the first pipeline 201, the first branch point 207 is connected to the second pipeline 202 of the water outlet of the water storage container through a third branch pipeline 208, and the downstream side of the first branch point 207 is divided into two pipelines, one pipeline is connected with the water storage container 120 and is provided with a first valve 501, and the other pipeline is a third branch pipeline 208 and is provided with a second valve 502. When hot water is needed to be output urgently, the first valve 501 can be closed, the second valve 502 is opened, and the hot water output by the boiler 110 is directly output without passing through the water storage container 120, so that the heat supply requirement can be met in time. Further, a third valve 503 may be disposed on the second pipe 202 at a downstream side of the connection point of the third branch pipe 208, and is used for controlling the hot water output from the water storage container 120.

When the quick return water is required to enter the boiler 110 for reheating, the sixth valve 506 and the fourth valve 504 can be closed, the fifth valve 505 is opened, and the return water directly enters the boiler 110 without passing through the water storage container 120.
Fig. 2 shows a schematic diagram of an energy storage device in another embodiment, which is different from fig. 1 in that the water storage container 120 is further connected to a supplementary heating system 150, which may be a solar heating system 151 or an air heating system (not shown), so that heat from the solar heating system 151 or the air heating system is transferred into the water storage container 120.

Such as solid-liquid phase change energy storage materials, solid-solid phase change energy storage materials, which are known in the related art, and mainly include polymers, layered perovskites, sodium sulfates, sodium acetates, fatty acids, polyols, and paraffins. In high-temperature seasons, the phase change energy storage unit can absorb heat supplied from the outside (such as air energy and electric boiler valley electricity energy storage), and the phase change material is changed from a solid state to a liquid state, absorbs a large amount of heat and stores the heat.

s106: and when the outlet water temperature is detected to be reduced to or below the target temperature t1, controlling the first control valve to be closed.
Therefore, the steps S104 to S106 are repeated, so that the output water temperature can be adjusted in real time and is always maintained at the preset temperature.
In some embodiments, the method further comprises:

In some embodiments, an indoor temperature sensor and an outdoor temperature sensor may be respectively disposed indoors and outdoors of the energy storage device, and when the indoor temperature sensor and the outdoor temperature sensor detect that the temperature reaches a certain threshold, the control unit may adjust the target water temperature output by the energy storage device.

The hardware matched with the control method can comprise one distribution box, one frequency converter, one PLC, one touch screen, three water pump strong-current elements, a plurality of temperature sensors (such as 4-6), and one man-hour wire accessory.
A more specific control flow is described below.
The first control valve is an electric two-way regulating valve, and the opening angle of the first control valve is regulated according to the outlet water temperature of the heating system. If the target value of the outlet water temperature is set to 50 ℃, the controller (PLC) continuously outputs a 4-20 milliampere signal to the electric regulating valve, and the target of stabilizing the outlet water temperature to 50 ℃ is achieved. When the water temperature continuously exceeds 50 ℃, the electric two-way regulating valve is opened to the highest limit. Namely, when the water temperature is lower than 50 ℃, the electric regulating valve is closed when reaching the lowest limit. The operation is started when the temperature is higher than 50 ℃, the operation is not interrupted, the aim of stabilizing the water outlet temperature by 50 ℃ is achieved, and the operation is usually maximized when the temperature 1 is continuously higher than 50+5 ℃. And the return water blocking system starts to start.
When the return water temperature is 50 degrees higher when the electric two-way regulating valve is opened to the maximum limit, the second control valve (specifically, the electric three-way switch valve) starts to work according to the action of the return water temperature sensor by 45 degrees. When the return water temperature is higher than 45 degrees +/-2 degrees, the three-way valve acts to open to enable the water return system to circulate, and when the return water temperature is lower than 45 degrees +/-2 degrees, the three-way valve acts to open the guide water storage container (water tank).
The heat storage variable frequency pump carries out PID adjustment according to the temperature difference between the two temperature collection points of the solar energy and the heat storage water tank. If the temperature difference is set to be 5 ℃, when the solar water temperature reaches 70 ℃, the water temperature of the heat storage water tank reaches 67 ℃, and the PLC monitors that the temperature difference is more than 5 ℃ and is more than half, the frequency converter is accelerated, and otherwise, the speed is reduced. The energy storage system is additionally provided with a timer so as to realize that the energy storage device works in the daytime and has a rest at night.
The inventive concept is explained in detail herein using specific examples, which are given only to aid in understanding the core concepts of the invention. It should be understood that any obvious modifications, equivalents and other improvements made by those skilled in the art without departing from the spirit of the present invention are included in the scope of the present invention.
