Specific embodiment
In the embodiment of the present invention, a kind of detection method of heat-reclamation multi-compressors air-conditioning system communication connection mistake is provided,
It includes step S1-S3.It is illustrated separately below.
Step S1: whether itself and pipeline control module are judged extremely by the tube temperature of interior machine when detection air-conditioner set operation
Between communication connection whether mistake, and the interior machine of communication connection mistake is marked.
Wherein, air-conditioner set after running for a period of time, detects the tube temperature of every unit, detects air-conditioner set
Whether abnormal interior machine tube temperature method be as follows:
When the control model of interior machine is heating operation, -5 DEG C of temperature of < system high pressure of interior machine inlet pipe temperature, then tube temperature is abnormal；
When the control model of interior machine is refrigerating operaton ,+10 DEG C of temperature of > system low-voltage of interior machine inlet pipe temperature, then tube temperature is abnormal.
All interior machines marked are successively numbered by A1 ~ An, and are controlled the numbered interior machine of institute and shut down, consequently facilitating to this
The practical corresponding interior machine of management control module controlled of machine is matched in a little.
The interior machine of label: being carried out the switching of control model by step S2, found out from other all interior machines tube temperature with it is described
The interior machine of the corresponding variation of control model, the interior machine found out are to control mould with the keep in communication pipeline of connection of the interior machine of the label
The practical interior machine controlled of block.
It should be noted that in this step, the switching of control model is carried out to the interior machine that will be marked one by one, then from it
The interior machine of tube temperature variation corresponding with the control model is found out in its all interior machine.In step S2, the interior machine of label is controlled
Before the switching of molding formula, first the interior machine of label is shut down, and the electric expansion valve for controlling the interior machine of all shutdown is opened, so that
Refrigerant can circulate in interior machine, and refrigerant state change caused by pipeline switches can be timely detected.The control model
Switching mode be from refrigeration shutdown mode be switched to heating shutdown mode or from heating shutdown mode be switched to refrigeration shut down
Mode.When carrying out above-mentioned switching to the control model of the interior machine of label, enter tube temperature degree phase in 10 seconds if there is other interior machines
When the changing value answered is more than 5 DEG C, then illustrate that it accesses the temperature change dramatically of the refrigerant of pipeline, it can be determined that the interior machine is
It keeps in communication with the interior machine of the label the practical interior machine controlled of pipeline control module of connection.
After the practical interior machine controlled of pipeline control module for finding out connection of keeping in communication with the interior machine of the label, if its
It is not labeled, is then marked, and found out by the way of step S2 and control mould with the pipeline of its connection of keeping in communication
The practical interior machine controlled of block.
In step s 2, after the switching that the interior machine of label is carried out to control model, if do not had from other all interior machines
The interior machine for finding tube temperature variation corresponding with the control model then illustrates the tube temperature abnormal conditions of interior machine appearance of the label simultaneously
Non- is caused by communication connection mistake, it may be possible to caused by other reasons, then cancel the label to the interior machine at this time.
Step S3: all interior machines marked find with the pipeline control module of its connection of keeping in communication is practical control in
After machine, air-conditioner set exports the address for the interior machine that every marks and the practical control of pipeline control module with its connection of keeping in communication
The address of the interior machine of system, and enter interim operational mode.
It should be noted that all interior machines marked are found and the practical control of the pipeline control module of its connection of keeping in communication
After the interior machine of system, before maintenance personal is not by communication connection error correction, air-conditioner set is run in temporary mode, and is guaranteed
The interior machine of most of communication connection mistake can also work normally, in the interim operational mode,
When certain logo note interior machine be switched on operation, and with its actual pipeline control module keep in communication connection interior machine be in stop
When machine mode, set the keep in communication interior machine of connection of the pipeline control module of the interior machine with the label to and the label
The corresponding shutdown mode of interior machine operational mode, because under corresponding refrigerating/heating shutdown mode, the company of refrigerating/heating pipeline
Connecing is conducting, and the interior machine of the label can also run corresponding mode using refrigerating/heating pipeline；
When certain logo note interior machine be switched on operation, and with its actual pipeline control module keep in communication connection interior machine be in fortune
When row mode, then the interior machine of the label can only with its actual pipeline control module keep in communication connection interior machine with identical
Mode operation because its connection refrigerant line and with its actual pipeline control module keep in communication connection interior machine connect
The refrigerant line connect is identical；
The operation if the interior machine of more logo notes is switched on simultaneously, is successively switched on, from big to small to guarantee to freeze by interior machine capacity
Amount/heating capacity meets the needs of every interior machine.
Further, in the interim operational mode, all interior machines marked all on a display screen prompt communication wrong,
Current operating conditions are interim operational mode.
In the embodiment of the present invention, a kind of heat-reclamation multi-compressors air-conditioning system, the heat recovery multiplex air conditioner are additionally provided
System is when detecting communication connection mistake, using the detection side of above-mentioned heat-reclamation multi-compressors air-conditioning system communication connection mistake
Method.
In conclusion the detection method of heat-reclamation multi-compressors air-conditioning system communication connection mistake of the invention and recuperation of heat are more
Online air-conditioning system, by the tube temperature of interior machine when detection air-conditioner set operation whether extremely come judge itself and pipeline control module it
Between communication connection whether mistake, and the interior machine of communication connection mistake is marked；The interior machine of label is subjected to control model
Switching, find out the interior machine of tube temperature variation corresponding with the control model from other all interior machines, the interior machine found out be with
The interior machine of the label is kept in communication the practical interior machine controlled of pipeline control module of connection, can be automatic under not shutdown status
Machine connection connection error in detecting, and identify correct connection type, it is convenient for after-sales service, can also be connected in interior machine connection
Guarantee that machine operates normally in major part, guarantees the usage experience of user when mistake as much as possible.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
