Detailed description of the invention
The attached drawing for constituting a part of the invention is used to provide further understanding of the present invention, schematic reality of the invention It applies example and its explanation is used to explain the present invention, do not constitute improper limitations of the present invention.In the accompanying drawings:
Fig. 1 is the control method flow chart of machine valve in multi-online air-conditioning system described in the embodiment of the present invention.
Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase Mutually combination.
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Embodiment 1
Such as Fig. 1, the present embodiment provides a kind of control methods of machine valve in multi-online air-conditioning system comprising following steps:
Step S1 obtains standard deliveries temperature T0, start air conditioner, detect outdoor environment temperature ToutIf Tout> A, interior machine Valve is with primitivation aperture P0Operation;
Step S2 detects actual exhaust air temperature T after end of run in step S11
Step S3, by step S2 actual exhaust air temperature T1With step S1 standard deliveries temperature T0It is compared, works as T1≥T0 When, the initialization aperture P of interior machine valve when being switched on to next time1Fitting amendment, the aperture for increasing the interior machine valve increase booting next time The aperture of machine valve in Shi Suoshu;Work as T1< T0When, next time, the aperture of interior machine valve remained unchanged when being switched on.
Wherein step S1 Plays delivery temperature T0For 100 DEG C≤T0≤ 110 DEG C, primitivation aperture P0For the air conditioner The interior machine valve opening of system default when starting, and in step S1 interior machine valve with primitivation aperture P0The time of operation is 1-3min, Preferred 2min in the present embodiment, i.e., interior machine valve is with primitivation aperture P0After running 2min, interior machine valve starts to automatically adjust.
Step S31, works as T1≥T0When air conditioner works normally, the initialization aperture P of interior machine valve when booting next time11 Fitting amendment, the air conditioner includes multiple indoor units, at least one indoor unit is in unlatching in multi-gang air-conditioner device at this time State, it can start for single machine, or multimachine starts simultaneously, at this time the initialization aperture P of interior machine valve11It is fitted modified Calculation formula is P11=P0+K(Tout- A), wherein 5≤K≤20,45 DEG C≤A≤50 DEG C.Under worst hot case, pass through initialization Delivery temperature and outdoor temperature in the process carry out accurate Correction and Control to the aperture of interior machine valve initialization, avoid next booting Excessive discharge temperature in interior machine valve initialization procedure causes subsequent interior machine valve events not fast enough, and delivery temperature rising is too fast, causes There is protection and shuts down phenomenon.
Step S32, one and only one indoor unit is in the open state in multi-gang air-conditioner device, and as single machine starts, when T1≥T0There is protection in Shi Suoshu air conditioner when shutting down, the aperture P of interior machine valve when record is shut down, when booting next time described in The initialization aperture P of interior machine valve12Fitting amendment, the initialization aperture P of interior machine valve12Being fitted modified calculation formula is P12=P0+ 0.4K1(P-P0), K1=K* (Tout-A)/(120-T1), wherein 5≤K≤20,45 DEG C≤A≤50 DEG C.The principle of this calculation formula It is, if after first time aperture is modified, running one section of realization and occurring being vented excessively high shutdown, initial opening is repaired before explanation After just, delivery temperature is still very high, interior machine valve regulation or not prompt enough, therefore increases amendment, and K1 is according to outdoor environment temperature Tout With delivery temperature T after initialization aperture1It is modified, that is to say, that environment temperature ToutHigher and initialization aperture exits Delivery temperature is higher, and K1 is modified bigger, therefore, can be according to delivery temperature and outdoor temperature after shutting down if there is protection It is fitted amendment initial opening, reduces the probability that next time, exhaust protection was shut down, system can normally start operation.
Therefore, the present embodiment is by delivery temperature and outdoor temperature in initialization procedure, to the aperture of interior machine valve initialization Accurate Correction and Control is carried out, the excessive discharge temperature in interior machine valve initialization procedure that is switched on next time is avoided, leads to subsequent interior machine valve Movement is not fast enough, and delivery temperature rising is too fast, leads to protection shutdown phenomenon occur;And it is shut down when single machine starting if there is protection Afterwards, the aperture of interior machine valve initialization can also be carried out accurate equally by delivery temperature and outdoor temperature in initialization procedure Correction and Control reduces the probability that next time, exhaust protection was shut down, air-conditioning system is enable normally to start operation.
