Metal hydride heat exchanger can make temperature reduce when discharging hydrogen, and work as metal hydride heat exchanger
When absorbing hydrogen, can temperature be increased.Equally, the powder of the metal hydride of dust formation can also make when discharging hydrogen
Obtaining temperature reduces, and when absorbing hydrogen so that temperature increases.
In this way, when if deposition has the powder of metal hydride in hydrogen paths, often applied when electrochemical compressor applies voltage
Add a forward voltage, when the powder of the metal hydride in the first hydrogen paths can discharge hydrogen so that position
Temperature reduce, and when the powder of the metal hydride in the second hydrogen paths can absorb hydrogen so that position
Temperature increases.Certainly, electrochemical compressor applies voltage and often applies a backward voltage, the metal in the first hydrogen paths
When the powder of hydride can absorb hydrogen so that the temperature of position increases, and the metallic hydrogen in the second hydrogen paths
When the powder of compound can discharge hydrogen so that the temperature of position reduces.
As it can be seen that can according to the temperature change of hydrogen paths come determine have in hydrogen paths metal hydride powder deposition
Sedimentation location simultaneously carries out corresponding unclog and readjust.Here, the temperature value of multiple positions in present hydrogen channel can be obtained.Hydrogen paths one
As be sealing, also, be all likely to result in metal hydride in the connector of hydrogen paths and the corner of hydrogen paths
The deposition of powder.Preferably, obtaining the connector of hydrogen paths or the temperature value of the corner of hydrogen paths.
In the embodiment of the present invention, since hydrogen itself does not need to storage heat, present hydrogen channel can be used non-
Heat-barrier material is made.In this way, can be obtained more in present hydrogen channel by the temperature-detecting device outside present hydrogen channel
The temperature value of a position.Such as：It is obtained using infrared temperature sensor outside present hydrogen channel multiple in present hydrogen channel
The temperature value of position.It can also be used some other temperature-detecting devices when having and obtain the temperature of present hydrogen channel corresponding position
Angle value.For example, placing Miniature temperature detector in the multiple positions in present hydrogen channel, communicated with corresponding Miniature temperature detector
After connection, you can obtain the temperature value of corresponding position.
Step 202：According to each temperature value of acquisition, determine that the powder for having metal hydride in present hydrogen channel deposits
Sedimentation location.
In this implementation, there can be the powder of metal hydride heavy in hydrogen paths to determine according to the temperature change of hydrogen paths
Long-pending sedimentation location.Therefore, can be according to multiple temperature values of acquisition, to determine the temperature change of hydrogen paths, and then determination is worked as
There is the sedimentation location of the powder deposition of metal hydride in preceding hydrogen paths.Wherein, it may include：If current temperature value with other extremely
When relative difference between few two temperature values is respectively greater than the first setting value, current location corresponding with current temperature value is determined
For sedimentation location.Such as：The temperature value of acquisition is 42.3 °, 42.1 ° and 41.5 ° respectively, in this way, 41.5 ° and other two
Relative difference between temperature value is respectively 0.8 and 0.6, respectively greater than the first setting value 0.3, you can determine and 41.5 ° it is right
The current location answered is sedimentation location.And the relative difference between 42.3 ° and other two temperature values is respectively 0.8, and
0.2, wherein 0.2 is less than the first setting value 0.3, then current location corresponding with 42.3 ° is not sedimentation location.
Certainly, in another embodiment of the present invention, according to each temperature value of acquisition, determine in present hydrogen channel there is metal
The sedimentation location of the powder deposition of hydride may also include：Numerical statistic is carried out according to each temperature value of acquisition, is determined current
The maximum probability temperature value of hydrogen paths；If current temperature value and the relative difference of maximum probability temperature value are more than the second setting value
When, determine that current location corresponding with current temperature value is sedimentation location.
Such as：The temperature value of acquisition includes：It is 30.5 °, 33.5 °, 33.5 °, 33.4 °, 33.6 °, 31.8 ° and 30.9 °, right
After it carries out mathematical statistics, 33.5 °, 33.5 °, 33.4 ° and 33.6 ° are distributed than comparatively dense, thus, it may be determined that maximum probability
Temperature value is 33.5 °, to, 30.5 ° are more than the second setting value 0.5 with 33.5 ° of relative differences for 3, to, it may be determined that with
30.5 ° of corresponding current locations are sedimentation location, are also sedimentation position with 31.8 ° and 30.9 ° of corresponding current locations equally
It sets, and is not then sedimentation location with 33.5 °, the 33.4 ° and 33.6 ° current locations answered.
Certainly, also sedimentation location can be determined according to other modes, such as：According to each temperature value of acquisition, determination is worked as
The corresponding current location of temperature value that peak value is in the temperature profile is determined as sinking by the temperature profile of preceding hydrogen paths
Decrease is set.Other modes are just not listed one by one.
Step 203：The powder of metal hydride on sedimentation location is unclogged and readjusted.
For the normal operation of guarantee air-conditioning system, the powder of the metal hydride in hydrogen paths must be just unclogged and readjusted in time,
Specify sedimentation location, you can unclogging and readjusting for the powder of metal hydride is carried out using corresponding strategy, such as：Ventilation process or
Person's chemical treatment etc..
As it can be seen that can be according to the Temperature Distribution of air-conditioning system hydrogen paths, determining has the powder of metal hydride in hydrogen paths
The sedimentation location of end deposition, the powder to carry out corresponding metal hydride are unclogged and readjusted.In this way, without dismantling air-conditioning system
In hydrogen paths, even component i.e. can determine sedimentation location and unclogged and readjusted, improve the efficiency that air-conditioning system channel is unclogged and readjusted,
Reduce the consuming to resource.
Certainly, in the embodiment of the present invention, it can not only determine the sedimentation location in hydrogen paths, can also carry out a step determination
The number of powder deposition, in this way, can further refine corresponding channel unclogs and readjusts strategy, such as：The big sedimentation of powder deposition
The corresponding wind-force in position is larger.Therefore, when sedimentation location has at least two, determine in present hydrogen channel there is metal hydride
Powder deposition sedimentation location after, further include：By the corresponding sedimentation location of maximum relative difference, it is determined as metal hydride
Maximum first sedimentation location of powder deposition of object.
It can be ranked up according to the size of relative difference, maximum relative difference corresponds to the powder deposition of metal hydride
Measure maximum first sedimentation location, the second largest relative difference corresponds to second largest the second sedimentation of powder deposition of metal hydride
Position, and so on, minimum relative difference corresponds to the N sedimentation locations of the powder deposition minimum of metal hydride.
The method that the embodiment of the present disclosure provides in operating process set to specific embodiment, will be illustrated below.
Embodiment one, in the present embodiment, air-conditioning system can as shown in Figure 1, also, present hydrogen channel it is logical for the first hydrogen
Road, after applying forward voltage due to electrochemical compressor, the first metal hydride heat exchanger discharges hydrogen, can temperature be dropped
Low, equally, the powder of the metal hydride in the first hydrogen paths also discharges hydrogen so that belongs to the powder deposition of hydride
Sedimentation location temperature be lower, therefore, can determine sedimentation location, and can be dredged according to the temperature change of the first hydrogen paths
Reason.
Fig. 3 is to show that the flow diagram of method is unclogged and readjusted in a kind of air-conditioning system channel that one goes out according to an exemplary embodiment,
As shown in figure 3, the process that air-conditioning system channel is unclogged and readjusted includes：
Step 301：Obtain the temperature value of multiple positions in the first hydrogen paths.
It here, can be by the temperature-detecting device outside hydrogen paths, for example, infrared radiation detection apparatus, obtains the first hydrogen
The temperature value of multiple positions in channel can be here the temperature value of five positions, such as：Respectively 35.3 °, 28.5 °,
34.8 °, 35.1 ° and 29 °.
Step 302：Numerical statistic is carried out according to each temperature value of acquisition, determines the maximum probability temperature in present hydrogen channel
Angle value.
If the temperature value obtained is respectively 35.3 °, 28.5 °, 34.8 °, 35.1 ° and 29, after carrying out numerical statistic,
It appears in that likelihood ratio in 34.8-35.3 is more, then can determine that the maximum probability temperature value in present hydrogen channel can be 35.07 °.
Step 303：Determine that the temperature value of an acquisition is current temperature value.
It can determine that a temperature value is current temperature value according to the sequencing of acquisition.Alternatively, arbitrarily obtaining a temperature
Value is current temperature value.
Step 304：Judge whether current temperature value and the relative difference of maximum probability temperature value are more than the second setting valueIf
It is to execute step 305, no person executes step 306.
In the present embodiment, the powder of the metal hydride of sedimentation location can discharge hydrogen in the first hydrogen paths, to meeting
So that the temperature of sedimentation location can be significantly lower than elsewhere, therefore, the second setting value can be 3.In this way, if current temperature value is
28.5, and the relative difference between maximum probability temperature value 35.07 is 6.57, is more than the second setting value 3, to execute step
Rapid 305.And if current temperature value is 35.3, and the relative difference between maximum probability temperature value 35.07 is 0.23, is less than the
Two setting values 3, to execute step 306.
Step 305：It determines that current location corresponding with current temperature value is sedimentation location, and is transferred to step 307.
Here, the temperature of current location corresponding with current temperature value and the temperature of the first hydrogen paths elsewhere are apparent
Difference, accordingly, it can be determined that current location is the sedimentation location for the powder deposition for having metal hydride.
Step 306：It determines that current location corresponding with current temperature value is not sedimentation location, and is transferred to step 307.
Step 307：Judge whether there is also the temperature values for being not determined to current temperature value for each temperature value obtainedIf
Have, return to step 303, no person, executes step 308.
Here, current temperature value can be first deleted from the temperature value of acquisition, then, if also remaining temperature value, returned
Step 303, no person executes step 308.
Step 308：The powder of metal hydride on sedimentation location is unclogged and readjusted.
Have determined that the sedimentation location in the first hydrogen paths, you can metal hydride is carried out using corresponding strategy
The dredging and improvement of powder reduce the influence transmitted to hydrogen.
Here, if sedimentation location is had at least two, by the corresponding sedimentation location of maximum relative difference, it is determined as metal
Maximum first sedimentation location of powder deposition of hydride.It can be ranked up according to the size of relative difference, maximum phase
Maximum first sedimentation location of powder deposition of metal hydride is corresponded to difference, the second largest relative difference corresponds to metal hydride
The second second largest sedimentation location of the powder deposition of object, and so on, minimum relative difference corresponds to the powder of metal hydride
The N sedimentation locations of deposition minimum.To which different strategies, such as the wind-force of ventilation can be used in different powder depositions
Difference, the powder for carrying out metal hydride in first hydrogen paths are unclogged and readjusted.
As it can be seen that in the present embodiment, it can be according to the Temperature Distribution of air-conditioning system hydrogen paths, determining has metal in hydrogen paths
The sedimentation location of the powder deposition of hydride, the powder to carry out corresponding metal hydride are unclogged and readjusted.In this way, without tearing open
Hydrogen paths in system of turning on the aircondition, even component can determine sedimentation location and be unclogged and readjusted, and improve air-conditioning system channel
The efficiency unclogged and readjusted reduces the consuming to resource.
Embodiment two, in the present embodiment, air-conditioning system can be as shown in Figure 1.Also, present hydrogen channel is logical for the second hydrogen
Road, after applying forward voltage due to electrochemical compressor, the second metal hydride heat exchanger absorbs hydrogen, can make temperature liter
Height, equally, the powder of the metal hydride in the second hydrogen paths also absorb hydrogen so that belong to the powder deposition of hydride
Sedimentation location temperature get higher, therefore, can determine sedimentation location, and can be dredged according to the temperature change of the first hydrogen paths
Reason.
Fig. 4 is to show that the flow diagram of method is unclogged and readjusted in a kind of air-conditioning system channel that two go out according to an exemplary embodiment,
As shown in figure 4, the process that air-conditioning system channel is unclogged and readjusted includes：
Step 401：Obtain the temperature value of three positions in the second hydrogen paths.
Step 402：Determine that the temperature value of an acquisition is current temperature value.
Step 403：Judge whether relative difference between current temperature value and other two temperature values is all respectively greater than the
One setting valueIf so, executing step 404, no person executes step 405.
Such as：The temperature value of acquisition is respectively 32.3 °, 32.5 °, 34.8 °, and the first setting value is 2, if current temperature value is
34.8 °, to, with the relative difference 2.5 between 32.3 °, the relative difference 2.3 being more than between the first setting value 2, with 32.5 °,
Also greater than the first setting value 2, thus, step 404 is can perform,；And if current temperature value is 32.3 °, to, between 32.5 °
Relative difference 0.3, be less than relative difference 2.5 between the first setting value 2, with 34.8 °, be more than the first setting value 2, to,
It is not both greater than setting value 2, to can perform step 405.
Step 404：It determines that current location corresponding with current temperature value is sedimentation location, and is transferred to step 406.
Current temperature value has clearly been higher than the temperature value of other positions, accordingly, it can be determined that corresponding with current temperature value
Current location is sedimentation location.
Step 405：It determines that current location corresponding with current temperature value is not sedimentation location, and is transferred to step 406.
Step 406：Judge whether there is also the temperature values for being not determined to current temperature value for each temperature value obtainedIf
Have, return to step 402, no person, executes step 407.
Here, it is searched in order, i.e., there is also next temperature values, you can return to step 402, no person execute step
