Defrosting, continues to heat.
In the specific embodiment of the invention, the defrosting Process flowchart variable of the first wind chamber is C1, and A1 represents the wind of the first wind chamber
Cavity pressure, B1 represents the wind chamber temperature of the first wind chamber, and the defrosting Process flowchart variable of the second wind chamber is C2, and A2 represents the second wind chamber
Wind cavity pressure, B2 represents the wind chamber temperature of the second wind chamber.
When Programmable detection to be currently double wind chamber type when, (this program has been also compatible with list to the control logic of the double wind chambers of operation
The control logic of wind chamber), A1 and B1, A2 and B2 is detected separately.
When A1, B1 value reach the lower limit of correspondence setting, make C1=1, corresponding fluorine system system enters defrosting, into except
C1=2 after frost, are detected when A, B sensor reach the higher limit of setting, make C1=3, and corresponding fluorine system system exits defrosting, continues to transport
Row is heated.
When the value of A2, B2 sensor reaches the lower limit of setting, another C2=1, corresponding fluorine system system enters defrosting, enters
C2=2 after defrosting, are detected when A, B sensor reach the higher limit of setting, another C2=3, and corresponding fluorine system system exits defrosting, continues
Operation is heated.
In the case that complete machine is heated, when detecting A2 and B2 reaches the lower limit specified, the corresponding fluorine system of the second wind chamber
System can enter defrosting；If now A1 and B1 are not reaching to the lower limit specified, the corresponding fluorine system system of the first wind chamber may proceed to fortune
Row is heated, until reaching defrosting condition.
When A2, B2 that the second wind chamber fluorine system is united reach specified higher limit, the second wind chamber fluorine system system can exit defrosting.First
Whether wind chamber fluorine system system enters or exits condition of the defrosting only according to A1 and B1, not by any influenceing of the second wind chamber fluorine system system.
That is C1 is only relevant with the wind chamber fluorine system system at place with C2 value, is independent of each other each other, therefore the operation of two wind chamber systems
State is independent of each other.
As C1=0, normal operation heats program；During C1=1, operation enters the program of defrosting, and control compressor is closed, four
Port valve commutation, blower fan are closed, and last compressor is reopened；During C1=2, it is constant to continue to defrosting control, while constantly detection
Whether satisfaction exits defrosting condition；During C1=3, defrosting program is exited in operation, compressor shutdown, four-way valve commutation, blower fan open,
Compressor is opened, and is completed after above-mentioned action, another C1=0 completes defrosting, continues to heat.
The defrosting Process flowchart variable of second wind chamber is C2, and the mode of C2 control defrostings is identical with C1.
Therefore, above-mentioned independent detection and the logic of control defrosting condition, can coordinate two fluorine system systems and carry out independent remove
Frost.
In the present embodiment by taking the non-double wind chamber types in parallel of four systems as an example, C1 and C2 respectively need to coordinate two parallel connection compressors
Defrosting (such as C1 coordinates compressor 1 and compressor 2, and C2 coordinates compressor 3 and compressor 4).
From the foregoing it can be that a kind of pair of wind chamber independence defrosting control method of the invention and system are set by using double wind chambers
Meter, and each wind chamber only corresponds to a fluorine system system, any pattern of fluorine system operation is all relatively more independent, it is to avoid multiple fluorine systems systems
Share the mistake defrosting caused by a wind chamber, it is ensured that the heating effect of multiple fluorine systems system unit operations.And the present invention passes through
The pressure and wind chamber temperature of each wind chamber are detected, so as to judge whether the corresponding fluorine system system of each wind chamber needs to enter defrosting still
Heat, so not only realize double wind chambers and independently defrost, also achieve a fluorine system system defrosting, another fluorine system system can be same
When the effect that heats, it is to avoid the problem of heating temperature drop during the defrosting that common wind chamber is brought.
Above is the preferable implementation to the present invention is illustrated, but the invention is not limited to the implementation
Example, those skilled in the art can also make a variety of equivalent variations or replace on the premise of without prejudice to spirit of the invention
Change, these equivalent deformations or replacement are all contained in the application claim limited range.

Single wind chamber process detection unit, for detecting the defrosting Process flowchart variable of current single wind chamber in real time, and is performed corresponding
Operation；
Single wind chamber defrosting entry condition detection unit, is less than default wind chamber pressure for working as the wind cavity pressure detected in single wind chamber
When power lower limit or wind chamber temperature are less than default wind chamber temperature upper limit value, corresponding defrosting Process flowchart variable is set to 1；
Single wind chamber defrosting exit criteria detection unit, is more than default wind chamber pressure for working as the wind cavity pressure detected in single wind chamber
When power higher limit or wind chamber temperature are more than default wind chamber temperature upper limit, corresponding defrosting Process flowchart variable is set to 3.
The control system 10. a kind of pair of wind chamber according to claim 7 independently defrosts, it is characterised in that：Described single wind chamber
Process detection unit includes：
Single wind chamber heating unit, for when defrost Process flowchart variable C=0 when, normal operation heats program；
The defrosting of single wind chamber enters unit, for as the Process flowchart variable C that defrosts=1, operation to enter defrosting program, control compression
Office is closed, four-way valve commutates, blower fan is closed, and finally controls compressor to reopen, and C is set into 2；
Detection unit is exited in the defrosting of single wind chamber, constant for as the Process flowchart variable C that defrosts=2, continuing to defrosting program,
Constantly detect whether that satisfaction exits defrosting condition simultaneously；
Unit is exited in the defrosting of single wind chamber, for as the Process flowchart variable C that defrosts=3, defrosting program to be exited in operation, is controlled successively
Compressor shutdown, four-way valve commutation, blower fan are opened and control compressor unlatching, complete after above-mentioned action, C is set into 0, completion
Defrosting, continues to heat.
