=1 changes heat transferring medium circulation direction (step S414) in the electrochemistry air-conditioning system, before specific switching mode can participate in
The embodiment for stating system switches the circulating direction of heat transferring medium by switching the on off state of each two-way valve；Step S417,
Heat transferring medium circulates after the completion of the switching of direction, and the hydrogen commutation signal and the heat transferring medium commutation signal are reset, that is, set
Set STRh2=0, STRsys=0；After the hydrogen commutation signal is reset, then system monitoring is less than this letter of STRh2=1
Number, then system for example it is aforementioned enter monitoring, alarming (step S408-S409), and, adjust supply voltage the step of (step S404-
S411)；
Step S408 and S409 describe the control method how sounded all clear after system alarm is examined if system alarm
After measuring SV=1 or SP=1 signals, according to current supply voltage Vin, its gear is gradually turned down, until system stop alarm；
Optionally, during step S408 and S409, S418 detection supply voltages Vin is all entered step after alarm every time
Whether it is more than 0, and determines that target gear, the target gear are less than the shelves of Vin values place gear level-one according to Vin values
Position；No longer it is that electrochemical compression device is powered if Vin is 0；Under normal circumstances, lowest gear will not be Vin is set as 0, and
It is to place it in gear that is minimum and maintaining system performance；In the process, a gear is often reduced, then return to step S403,
If system is still alarmed, then executes the operation for reducing gear in the step S408 and S409.
