Fig. 1 is a kind of structure diagram of air-conditioning shown according to an exemplary embodiment.As shown in Figure 1, the air-conditioning packet
It includes：Electrochemical compressor 100 and two metal hydride heat exchangers, here, for ease of hereinafter to the explanation of embodiment,
Two metal hydride heat exchangers are defined into the first metal hydride heat exchanger 200 and the second metal hydride heat exchanger respectively
300, two ports of electrochemical compressor 100 are separately connected two metal hydride heat exchangers, wherein electrochemical compressor
100 first port 110 is connect with the first metal hydride heat exchanger 200, the second port 120 of electrochemical compressor 100 with
Second metal hydride heat exchanger 300 connects.
In this way, electrochemical compressor 100 is exchanged heat by first port 110 and second port 120 to the first metal hydride
When device 200 and the second metal hydride heat exchanger 300 apply primary voltage, a metal hydride heat exchanger release hydrogen may make
Gas, and another metal hydride heat exchanger absorbs hydrogen.Such as：First port 110 is anode, and second port 120 is cathode,

300 external heat release of compound heat exchanger, to freeze to indoor environment using the metal hydride heat exchanger of heat absorption, reach
To the purpose for reducing room temperature.
General hydrogen conveying flow path is sealing, and still, the connectivity port of electrochemical compressor or hydrogen convey flow path
Other parts easily there is poorly sealed problem, might have some hydrogen from hydrogen convey flow path in reveal, lighter in weight
Some metal hydride powders can leak out hydrogen delivery tube road together with hydrogen, and carried out with the dew being condensed out in air-conditioning
Reaction so that conductive metal hydride changes, and changes the acid-base value of the outer surface of air-conditioning interior section component.
Therefore, in the embodiment of the present invention, it can determine that hydrogen conveying flow path is revealed according to the variation of the acid-base value of metal hydride
Failure, to which whether the leakproofness for detecting air-conditioning is good.
Fig. 2 is a kind of safety detection method of the air-conditioning of Applied Electrochemistry compressor shown according to an exemplary embodiment
Flow diagram, as shown in Fig. 2, the process of safety detection method includes：
Step 201：When determining satisfaction setting inspection condition, be set to hydrogen conveying flow path at least one group is obtained
At the acid-base value sample value of at least one sampled point of the outer surface of component；
Step 202：When the acid-base value sample value of at least one sampled point and the pH value of setting mismatch, really
There is leakage failure in the fixed air-conditioning.
In the embodiment of the present invention, air-conditioning includes：Electrochemical compressor, and distinguish with two ports of electrochemical compressor
The the first metal hydride heat exchanger and the second metal hydride heat exchanger of connection.In metal hydride heat exchanger absorption refrigeration
When, the dew of condensation is concentrated mainly on the outer surface of metal hydride heat exchanger, in this way, there are two metal hydrides to exchange heat for air-conditioning
Device sampled point can be arranged on the outer surface in any one metal hydride heat exchanger.
Preferably, sampled point is set to the outer surface of the bottom of metal hydride heat exchanger, exchange heat in metal hydride
When the dew that device is condensed out is more, dew can gradually converge into the bottom of metal hydride heat exchanger under the effect of gravity
Therefore sampled point is set to the outer surface of the bottom of metal hydride heat exchanger by portion, can detect more dew samples
This, improves the accuracy of acid-base value detection.
In step 201, optionally often apply primary voltage since electrochemical compressor applies voltage, you can so that hydrogen
Flow path is conveyed by hydrogen to move from a metal hydride heat exchanger to another metal hydride heat exchanger, it therefore, can basis
Alive number is applied inspection condition is arranged, in this way, in this implementation, determines that meeting setting inspection condition includes：Obtain electrification
It learns compressor and applies alive current numerical value, wherein electrochemical compressor applies primary voltage so that hydrogen is defeated by hydrogen
Flow path is sent to be moved from the first metal hydride heat exchanger to the second metal hydride heat exchanger；When the second metal hydride heat exchanger
When the current secondary numerical value that the conveying of single hydrogen is completed, and obtained is matched with setting value, determines and meet setting inspection condition.
Such as：Setting value includes：1,11,21,31 ..., if in this way, electrochemical compressor applies voltage, and this for the first time
After secondary hydrogen transmission process, current numerical value can be matched with setting value, since setting value includes：1、11、21、
31 ... and setting value in include current numerical value, that is, when the current secondary numerical value obtained match with setting value, determine that satisfaction is set
Inspection condition, so as to further obtain the acid-base value sample value of metal hydride in current metal hydride heat exchanger.Alternatively,
Electrochemical compressor the 20th once applies voltage, after this hydrogen transmission process, due to including current in setting value
Secondary numerical value 21 when the current secondary numerical value obtained is matched with setting value, determines and meets setting inspection condition.And electrochemical compressor
20th applies voltage three times, after this hydrogen transmission process, due to not including current numerical value 23 in setting value, i.e.,
When the current secondary numerical value obtained is mismatched with setting value, determines and be unsatisfactory for setting inspection condition.
Wherein, hydrogen conveys flow path from the first metal hydride heat exchanger to the second metal hydride heat exchanger by hydrogen
It, can be by determining whether the second metal hydride heat exchanger completes the conveying of this hydrogen, to determine that this hydrogen conveys when mobile
Whether process finishes.And determine that the process whether the second metal hydride heat exchanger completes the conveying of this hydrogen is various, example
It such as, can be according to the amounts of hydrogen that the amounts of hydrogen that the first metal hydride heat exchanger discharges is absorbed with the second metal hydride heat exchanger
Comparison result determines that, alternatively, can be determined according to hydrogen content in metal hydride heat exchanger, detailed process is just not repeated
.
As it can be seen that interval n times hydrogen exchange process, can carry out the soda acid of metal hydride in current metal hydride heat exchanger
Spend the acquisition of sample value.The natural integer that N can not set.Such as：5,8,10,20 etc..
Optionally, can also inspection condition be set according to the run time of air-conditioning, that is, meeting setting inspection condition includes：It obtains
Take the current run time of current air-conditioning；When current run time is matched with setting run time, determine that meeting setting checks
Condition.
Such as：Setting run time includes：0 minute, 10 minutes, 20 minutes ..., in this way, air-conditioning booting operation when, currently
Run time is 0 minute, is matched with setting run time, you can determines and meets setting inspection condition.And current run time is 8
Minute, it is mismatched with setting run time, you can determine and be unsatisfactory for setting inspection condition.Certainly, current run time is 20 points
Clock is matched with setting run time, you can is determined and is met setting inspection condition.
As it can be seen that M minutes run times can be spaced, it is determined whether carry out the acquisition of the acid-base value sample value of sampled point.M can
The natural integer not set.Such as：3,5,8,10,15 etc..
The method for obtaining the acid-base value sample value of sampled point can be various, such as be examined by a PH meter or acid-base value
Survey instrument, you can obtain the acid-base value sample value of current sampling point.Such as：The detection terminal of acidity-basicity tester is placed on and is set
For the outer surface of the component of sampled point, you can obtain the acid-base value sample value of current sampling point by acidity-basicity tester.
In step 202, air-conditioning saves the pH value of setting, in this way, by the acid-base value sample value of sampled point and storage
PH value be compared, if the two mismatch, you can determine air-conditioning hydrogen conveying flow path in the presence of leakage hang over.Wherein,
Hydrogen conveying flow path is after electrochemical compressor applies voltage, and hydrogen passes through electrochemical compression from the first metal hydride heat exchanger
Machine carries out mobile transmission channel to the second metal hydride heat exchanger.
Wherein, acid-base value sample value and when the unequal pH value of setting, it may be determined that the two mismatches.Alternatively, soda acid
When the relative difference spent between sample value and the pH value of setting is more than setting difference, it also can determine that the two mismatches.
Such as：PH value is identified with pH value, if by PH meter obtain acid-base value sample value be 8.5, and keep with
The pH value set then can determine that the acid-base value of sampled point is changed as 8.1, and then can determine the hydrogen conveying of air-conditioning
Flow path is revealed.Alternatively, be 9.5 by the acid-base value sample value that PH meters obtain, and the pH value set is 9.2, the two
Between relative difference 0.3, be more than setting difference 0.2, you can determine that the acid-base value of current sampling point is changed, Jin Erke
Determine air-conditioning hydrogen conveying flow path there are hydrogen leaks.
Certainly, if acid-base value sample value is matched with the pH value of setting, i.e., golden in current metal hydride heat exchanger
The acid-base value for belonging to hydride does not change, and steam is not leaked into the hydrogen conveying flow path to can determine air-conditioning, i.e., empty
Adjust leakproofness good.And when acid-base value sample value and the pH value of setting mismatch, determine the hydrogen conveying flow path of air-conditioning
There are leakage, being sealed property maintenance, to reduce the probability for releasing metal hydride heat exchanger outside hydrogen, reduce metal
The probability that hydride is rotten, is reduced, ensures and improves the service life of metal hydride, further improve what air-conditioning used
Service life.
Optionally, after determining that the hydrogen conveying flow path of air-conditioning has leakage failure, further include：Acid-base value sample value is true
It is set to the pH value of new setting.
In this way, pH value can real-time update, improve the accuracy of air-conditioning safety detection, obtained twice as long as front and back
PH value mismatches, you can determines in the hydrogen conveying flow path of air-conditioning and leaks into steam.So as to on-call maintenance, further carry
The service life of high air-conditioning and safety.
In this way, when operation of air conditioner starts, the acid-base value sample value of sampled point may be obtained, and the storage soda acid preserved
Angle value may not have, at this point, acid-base value sample value can be updated to the pH value of setting without comparing, and preserve, this
Testing process terminates.To in next air-conditioning sealing propertytest flow, obtain the new acid-base value sample value of sampled point
Afterwards, acid-base value sample value can be compared with the pH value set before.Therefore, optionally, when acid-base value sample value with
When the pH value of setting mismatches, before determining that leakage failure occurs in the hydrogen conveying flow path of air-conditioning, further include：It is protected when determining
When having the pH value of setting, acid-base value sample value is matched with the pH value of setting.And when determination is not preserved
