Optionally, a distribution valve 5 is provided at the connection of the water inlet line 1 to the tempering line 3 and/or at the connection of the tempering line 3 to the water outlet line 2. When the distribution valve 5 is arranged at the communication position of the water inlet pipeline 1 and the temperature adjusting pipeline 3, the flow dividing proportion of the water body can be controlled; when the distribution valve 5 is arranged at the communication part of the temperature adjusting pipeline 3 and the water outlet pipeline 2, the confluence proportion of the water body can be controlled. Alternatively, the distribution valve 5 is a solenoid valve. The water quantity proportion of different pipe sections can be adjusted by adjusting the electromagnetic valve.
The second heating means 6 is arranged to heat the water flow of the water outlet line 2. The second heating means 6 is arranged to heat the body of water flowing through the outlet conduit 2. If the water body is not heated to the required temperature through the temperature adjusting pipeline 3, the supplementary heating can be carried out through the second heating device 6, so that the water temperature reaches the required temperature. Optionally, the second heating means 6 is an electric heating means. The electric heating device can realize the rapid heating of the water body. The heating pressure of the first heating means 4 can be relieved by adjusting the heating power of the second heating means 6.
Optionally, the first heating device 4 is an electric heating device. The body of water circulating within the first pipe section 31 is heated by the electric heating means.
Optionally, the first heating device 4 is a heat exchange device. The heat exchange device heats the water body through heat exchange. Optionally, a phase change heat storage material capable of storing heat is arranged inside the heat exchange device, and the phase change heat storage material exchanges heat with the water body, so that the temperature of the water body circulating in the first pipe section 31 is increased. The temperature adjusting range of the heat exchange device is limited, and when the heating range of the required water body is higher, the adjusting target is realized by matching with the second heating device 6.
As shown in fig. 2, the method for adjusting the dc water heating apparatus includes:
s201, determining a target heating amplitude and a maximum adjusting amplitude of a temperature adjusting pipeline;
s202, judging whether the target heating amplitude is larger than the maximum regulating amplitude of the temperature regulating pipeline or not; if yes, executing step S204, otherwise executing step S203;
s203, determining the proportion of the water quantity entering the second pipe section according to the first mode, and correspondingly adjusting a distribution valve;
s204, determining the proportion of the water quantity entering the second pipe section according to the second mode, adjusting the distribution valve correspondingly, and adjusting the second heating device.
According to the comparison result between the target heating amplitude and the maximum adjusting amplitude of the temperature adjusting pipeline, the proportion of the water quantity entering the second pipe section is adjusted in different modes, so that the adjusting amplitude of the temperature adjusting pipeline is adjusted; and according to the comparison result between the target heating amplitude and the maximum adjusting amplitude of the temperature adjusting pipeline, adjusting the second heating device, and finally realizing the mutual matching of the heating of the temperature adjusting pipeline and the second heating device, so that the adjusting amplitude of the temperature adjusting pipeline is in a proper range, and the fault caused by the overlarge adjusting amplitude born by the temperature adjusting pipeline is avoided. If the adjusting amplitude of the temperature adjusting pipeline is too large, the water body needs to completely flow into the first pipe section and be heated by the first heating device, and the water body heating load of the first heating device is too large.
The target heating amplitude is the absolute value of the difference between the final heating temperature of the water body and the water inlet temperature of the water inlet pipeline. For example, if the feed water temperature is 20 ℃ and the final heating temperature is 95 ℃, the target heating range is 95 ℃ to 20 ℃ =75 ℃. Optionally, the target heating amplitude is a preset heating amplitude. That is, the target heating amplitude may be a heating amplitude preset by a user, and is determined by calling up the preset heating amplitude. The maximum adjusting amplitude of the temperature adjusting pipeline refers to the maximum adjusting amplitude of the temperature adjusting pipeline for the water body. For example, the temperature of the body of water can be raised by 30 ℃, 50 ℃ or 70 ℃. The maximum adjusting amplitude can be obtained by respectively arranging temperature sensors on the water inlet pipeline and the water outlet pipeline to enable the water body to completely enter the first pipe section, and then calculating the temperature difference value by detecting the temperatures of the water inlet pipeline and the water outlet pipeline to obtain the maximum adjusting amplitude of the temperature adjusting pipeline.
If the target heating amplitude is smaller than or equal to the maximum adjusting amplitude of the temperature adjusting pipeline, the water body can directly reach the target heating amplitude through the temperature adjusting pipeline by adjusting the distribution valve. For example, the maximum regulating amplitude of the temperature regulating pipeline is 70 ℃, the target heating amplitude is 65 ℃, and the water body flows into the first pipe section and the second pipe section respectively according to a certain proportion by regulating the distribution valve and then merges, so that the water with the temperature of 65 ℃ is formed. Optionally, adjusting the distribution valve comprises adjusting a distribution valve disposed at a communication of the water inlet line and the tempering line. This allows the ratio of the amount of water entering the first and second sections to be adjusted.
If the target heating amplitude is larger than the maximum adjusting amplitude of the temperature adjusting pipeline, for example, the target heating amplitude is 100 ℃, and the maximum adjusting amplitude of the temperature adjusting pipeline is 70 ℃, which indicates that the temperature adjusting capacity of the temperature adjusting pipeline is insufficient, the second heating device needs to be started to assist in temperature rise, so that the water body reaches 100 ℃. The water body is heated to a target heating range by the two-stage heating. Therefore, the adjusting amplitude of the temperature adjusting pipeline can be properly reduced, the water which originally and completely flows into the first pipe section is enabled to flow into the second pipe section through adjusting the distributing valve, the water quantity flowing into the first pipe section is reduced, and the heating load of the first heating device is reduced.
In some embodiments, determining the proportion of water entering the second pipe segment according to a first manner comprises:
and determining the proportion of the water entering the second pipe section according to the heating temperature of the first heating device, the water temperature of the second pipe section and the target heating amplitude.
The heating temperature of the first heating device and the water temperature of the second pipe section are obtained by arranging temperature sensors at the corresponding positions of the first heating device and the second pipe section. Optionally, the heating temperature of the first heating device is determined by a temperature sensor arranged at the first pipe section. For example, if the temperature sensor detects that the temperature of the first pipe segment is 60 ℃, the heating temperature of the first heating device is determined to be 60 ℃. Optionally, the water temperature of the second pipe section is determined by a temperature sensor arranged in the second pipe section. For example, if the temperature sensor detects a water temperature of 15 ℃ in the second pipe section, the water temperature of the second pipe section is determined to be 15 ℃. Optionally, the water temperature of the second pipe section is equal to the water temperature of the water inlet pipeline. The second pipe section is theoretically equal to the water temperature of the water inlet pipeline because the second pipe section is not heated.
Optionally, the target heating amplitude, the heating temperature of the first heating device and the water temperature of the second pipe section are substituted into a calculation formula to calculate and determine the proportion of the water quantity entering the second pipe section. In this way, a suitable water amount ratio can be obtained in combination with the temperature factor. And adjusting the opening degree of the distribution valve according to the proportion of the water quantity entering the second pipe section, so as to distribute the water quantity entering the first pipe section and the second pipe section.
In some embodiments, the proportion of water entering the second pipe section is determined by the following calculation:
X=[△T’/(T1-T2)]+1；
wherein X is the water quantity ratio entering the second pipe section, T1 is the water temperature of the second pipe section, T2 is the heating temperature of the first heating device, and DeltaT' is the target heating amplitude.
Illustratively, Δ T' =55 ℃, T2=75 ℃, T1=15 ℃,
X=[△T’/(T1-T2)]+1=[55/(15-75)]+1≈0.08。
it is shown that when the target heating amplitude is 55 c, the distribution valve is adjusted to give a ratio of 0.08 water into the second section and correspondingly a ratio of 1-0.08=0.92 water into the first section. Therefore, water with the target heating amplitude of 55 ℃ can be obtained after the water body passes through the temperature regulating pipeline.
In some embodiments, determining the proportion of water entering the second pipe segment according to the second manner comprises:
and determining the proportion of the water quantity entering the second pipe section according to the preset adjusting amplitude of the temperature adjusting pipeline, the water temperature of the second pipe section and the heating temperature of the first heating device.
And determining the proportion of the water quantity entering the second pipe section by combining the temperature factors of the temperature regulating pipeline, the second pipe section and the first heating device. The water temperature of the second pipe section and the heating temperature of the first heating device can be detected by the temperature detection device. The preset adjusting amplitude of the temperature adjusting pipeline is the preset adjusting amplitude. For example, the preset adjustment range is 60 ℃, 65 ℃, 70 ℃ and the like. The preset adjusting range is used for enabling the temperature adjusting pipeline to adjust the temperature according to the preset adjusting range.
In some embodiments, the proportion of water entering the second pipe section is determined by the following calculation:
Y=[△T1/(T1-T2)]+1；
wherein Y is the water quantity ratio entering the second pipe section, Delta T1 is the preset adjusting amplitude of the temperature adjusting pipeline, T1 is the water temperature of the second pipe section, and T2 is the heating temperature of the first heating device.
As an example, when Δ T1=60 ℃, T1=5 ℃, T2=70 ℃,
Y=[△T1/(T1-T2)]+1=[60/(5-70)]+1≈0.08
it is shown that by adjusting the distribution valve, the ratio of the water flowing into the second pipe section is 0.08, and the ratio of the water flowing into the first pipe section is 1-Y =1-0.08=0.92, so that the water temperature can reach the target heating amplitude.
In some embodiments, the absolute value of the difference between the preset adjustment amplitude and the maximum adjustment amplitude of the temperature adjusting pipeline is a, and a is greater than or equal to 5 and less than or equal to 15. Therefore, the adjusting pressure of the temperature adjusting pipeline can be reduced, and the final heating effect on the water body is not influenced. The water in the direct current water heating device is heated instantaneously, and if the adjusting amplitude of the temperature adjusting pipeline is reduced too much, the water body may not reach the target heating amplitude after being heated by the second heating device. When a is more than or equal to 5 and less than or equal to 15, the regulation pressure can be reduced, and the final heating effect on the water body is not influenced. In one example, the maximum adjustment amplitude is 70 ℃, a is 10, and the preset adjustment amplitude is 70-10=60 ℃.
In some embodiments, adjusting the second heating device comprises: according to the heating amplitude of the second heating device, the heating power of the second heating device is determined, and the second heating device is adjusted accordingly. The second heating device further realizes the adjustment of the heating amplitude by adjusting the heating power. The heating power needs to be determined according to the heating amplitude of the second heating means. The heating amplitude of the second heating device is related to the target heating amplitude and the adjusting amplitude of the temperature adjusting pipeline, and the heating amplitude of the second heating device can be determined through a calculation formula on the basis of determining the target heating amplitude and the adjusting amplitude of the temperature adjusting pipeline.
In some embodiments, the heating amplitude of the second heating device is determined by the following calculation:
△T2=△T’-△T1；
wherein, Δ T2 is the heating amplitude of the second heating device, Δ T' is the target heating amplitude, and Δ T1 is the preset adjusting amplitude of the temperature adjusting pipeline.
The target heating amplitude is obtained after the water body is heated by the temperature adjusting pipeline and the second heating device in two stages, and after the target heating amplitude and the adjusting amplitude of the temperature adjusting pipeline are determined, the heating amplitude of the second heating device can be obtained through difference calculation.
Exemplarily, Δ T '= 95 ℃, # T1=65 ℃, # T2= Δ T' —. Δ T1=95-65=30 ℃. The heating amplitude of the second heating means is 30 deg.c.
In some embodiments, the heating power of the second heating device is determined by the following calculation:
p=70*v*△T2；
where p is the heating power of the second heating means, Δ T2 is the heating amplitude of the second heating means, and v is the flow rate of water flowing through the second heating means.
The heating power of the second heating means is determined according to the flow rate of water flowing through the second heating means and the heating amplitude of the second heating means. The flow rate of the water flowing through the second heating device can be detected by arranging a flow rate sensor on the water outlet pipeline. According to the calculated heating power, the heating power of the second heating device can be adjusted, and then the heating amplitude of the second heating device is adjusted.
It should be understood that the above-described conditioning method may also be used for cooling conditioning of a body of water. And replacing the first heating device and the second heating device with a first refrigerating device and a second refrigerating device respectively, adjusting the water quantity entering the first pipe section according to the same method, and controlling the opening and closing of the second refrigerating device.
The direct current water heating device is controlled by the direct current electromagnetic valve, is powered by direct current, can be switched on and off frequently, and has higher reliability and long service life. Dc solenoid valves are used to control important electrical circuits. In order to realize the rapid and accurate adjustment of the water temperature, the direct current electromagnetic valve can be arranged for accurate control. Optionally, the second heating device is a direct current heating device. Therefore, the heating power can be quickly adjusted by changing the direct current driving voltage, and the temperature can be accurately controlled.
