It thaws control, failure is freezed in determination in time, and carries out control of thawing to it, and without other devices, control method simply has
Effect, it is energy saving.
In some optional embodiments, electrochemistry air-conditioning 1 further includes duration matching module, is used for:
Based on the surface temperature of the metal hydride heat exchanger in indoor, matches and obtain from preset duration set
Two metal hydride heat exchangers are interchangeable the duration of thawing after operation；Duration set includes multiple corresponding different metal hydrogenations
The set of the duration of thawing for freezing to thaw completely under failure of object surface temperature.
Wherein, control is thawed in the presence of the metal hydride heat exchanger for freezing failure, can be passed through and be changed power supply application
To the voltage direction of electrochemical compressor 20, become the voltage direction for being applied to electrochemical compressor 20 and original state phase negative side
To voltage, the metal hydride heat exchanger in indoor originally under hydrogen release heat absorption state become in inhale hydrogen heat release state
Under.
Optionally, control, which exists, freezes the duration that the metal hydride heat exchanger of failure thaws, can be by default
The duration of thawing of the surface temperature of multiple corresponding different metal hydride heat exchangers, the duration of thawing can be used for characterizing in the presence of jelly
The metal hydride heat exchanger of knot failure thaws the data of time used completely, obtains duration set, which includes more
The duration of thawing of the surface temperature of a corresponding different metal hydride heat exchanger, when the metal hydride in indoor of acquisition
The surface temperature of heat exchanger determines the metal hydride heat exchanger in the presence of when freezing failure, and control point is in indoor and outdoor
Two metal hydride heat exchangers of side are interchangeable operation, and the metal hydride heat exchanger for making aforementioned presence freeze failure is in
Hydrogen heat release state is inhaled, the duration obtains the metal hydride heat exchanger detected with temperature-detecting device in duration set
The duration of thawing that matches of surface temperature.
The embodiment of the present disclosure increases the metal hydride heat exchanger in indoor during electrochemistry operation of air conditioner
It thaws control, failure is freezed in determination in time, and carries out control of thawing to it, and without other devices, control method simply has
Effect, it is energy saving.
In some optional embodiments, electrochemistry air-conditioning 1 further includes voltage matches module, is used for:
Based on the surface temperature of the metal hydride heat exchanger in indoor, matches and obtain from preset voltage set
Two metal hydride heat exchangers are interchangeable the voltage that thaws of the electrochemical compressor 20 after operation；Voltage set be it is multiple not
