Problems solved by technology
Generally, the hydrogen channel is sealed, but the connection port of the electrochemical compressor or other parts of the hydrogen channel are prone to poor sealing, and some water vapor will flow into the hydrogen channel, so that the water vapor enters the metal hydride exchange with the hydrogen. After the heat exchanger, it will react with the metal hydride to generate alkaline substances and hydrogen gas, resulting in the deterioration of the metal hydride, which will reduce the amount of available metal hydride stored in the metal hydride heat exchanger. Ensuring the lifetime of metal hydrides is critical

The invention discloses a sealing performance detecting method of an air conditioning system and the air conditioning system, and belongs to the technical field of air conditioners. The air conditioning system comprises an electrochemical compressor, a first metal hydride heat exchanger, a second metal hydride heat exchanger, and at least one conductor which is positioned in a hydrogen channel ofthe electrochemical compressor, wherein the hydrogen channel conveys hydrogen with the first metal hydride heat exchanger and the second metal hydride heat exchanger; and after the conductor chemically reacts with water, the conducting performance of the conductor changes. The method comprises the steps of acquiring current conducting performance value of the current conductor after determining that the set examination conditions are met, wherein the current conductor is any one of the at least one conductor; and if the current conducting performance is not matched with the stored conducting performance value corresponding to the current conductor, determining that water vapor leaks into the hydrogen channel of the air conditioning system.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to a method for detecting the airtightness of an air conditioning system and the air conditioning system. Background technique [0002] Along with the raising of living standard, air conditioner is used more and more generally. At present, most air conditioners, especially household air conditioners, use vapor compression refrigeration. The refrigerant in this refrigeration method is fluoride. The release or leakage of this refrigerant will cause harm to the environment. Therefore, fluorine-free air conditioners have been gradually developed and used. up. [0003] At present, the fluorine-free air-conditioning system may include: an electrochemical compressor, and two ports of the electrochemical compressor are respectively connected to a first metal hydride heat exchanger and a second metal hydride heat exchanger, so that the electrochemical compression When a forward vo...
