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.

Afterwards, interior machine valve starts to automatically adjust;
Step S2 detects actual exhaust air temperature T after end of run in step S11It is 120 DEG C;
Step S3, by step S2 actual exhaust air temperature T1With step S1 standard deliveries temperature T0It is compared, finds T1>T0
When, the initialization aperture P of interior machine valve when being switched on to next time11Fitting amendment increases the aperture of interior machine valve when booting next time, i.e.,
Pass through the initialization aperture P of interior machine valve11Calculation formula be P11=P0+K(Tout- 48) it calculates, wherein K is preferably 20, under acquisition
The initialization aperture P of interior machine valve when secondary booting11=160+20* (55-48)=300, then interior machine valve will be made when booting next time with 300
For the operation of primitivation aperture, therefore, the present embodiment is by passing through delivery temperature in initialization procedure and outdoor under worst hot case
Temperature carries out accurate Correction and Control to the aperture of interior machine valve initialization, increases the aperture of the interior machine valve, make its delivery temperature
Declined, avoid the excessive discharge temperature in interior machine valve initialization procedure that is switched on next time, cause subsequent interior machine valve events not fast enough,
Delivery temperature rising is too fast, leads to protection shutdown phenomenon occur.
