Factor a1、a2、a3、a4、a6、a7、a8And a9Weight be respectively set to 0.05.The most now flow is adjudicated in matrix each is sentenced
Certainly the value of the factor is sued for peace after the quadrature respectively of corresponding weight again, and obtaining summed result is 0*0.05+0*0.05+0*
0.05+0*0.05+1*0.6+0*0.05+0*0.05+ (-1) * 0.05+ (-1) * 0.05=0.5, so time determine current flow
Change request is that flow increases request, therefore meets the demand of current refrigeration system test.
