In a kind of optional embodiment, in order to enable flow control result is more accurate, adjudicated according to the flow
Before matrix obtains current changes in flow rate request, the method further includes:
The factor is adjudicated for each of flow judgment matrix and assigns different weights, is then again adjudicated flow each in matrix
It sums again after the value and corresponding weight respectively quadrature of a judgement factor, if summed result is more than 0, it is determined that current

601~800 turns, the first difference threshold is 2 DEG C.
It is so following F according to the judgement matrix that the current working condition of refrigerator obtains1:
In this case, if the flow is directly adjudicated matrix F1In it is each judgement the factor value sum, ask
It is -1 with result, it is determined that current changes in flow rate request is that flow reduces request, should reduce the work shape of cooling assembly at this time
State.If certain commonly used situation, current refrigerator will reduce the working condition of cooling assembly really, because compartment temperature is less than
Temperature set by user, rotation speed of fan are also higher.But due to being currently in refrigeration system test mode, so when more think
The purpose reached is:The refrigeration effect most Canon of test refrigerator reaches any temperature.And it is not desired to reduce the work of cooling assembly at this time
Make state, therefore can solve to encounter under refrigeration system test mode by way of weight is arranged in this case above-mentioned
Problem.For example, will with whether be that refrigeration system tests relevant judgement factor a5Weight be set as 0.6, and by other judgements
Factor a1、a2、a3、a4、a6、a7、a8And a9Weight be respectively set to 0.05.So sentence at this time by each in flow judgement matrix
It certainly sums again after the value of the factor and corresponding weight respectively quadrature, it is 0*0.05+0*0.05+0* to obtain summed result
0.05+0*0.05+1*0.6+0*0.05+0*0.05+ (- 1) * 0.05+ (- 1) * 0.05=0.5, so when determine current flow
Change request is that flow increases request, therefore meets the demand of current refrigeration system testing.
Wherein, the weight of each judgement factor can need to be arranged according to real work, unfixed to require, and only meet
All the sum of the weight of the judgement factor is equal to 1.
In a kind of optional embodiment, above-mentioned steps 102 determine current flow according to the request of the changes in flow rate of acquisition
Adjustment direction, including:
If current changes in flow rate request is that flow increases request, it is determined that current flow adjustment direction is to increase flow
Direction;
If current changes in flow rate request is that flow-reduction is asked, it is determined that current flow adjustment direction is to reduce flow
