+> 0, i.e. T
2> T
in+ △ T
+, illustrate relative to indoor environment temperature T
in, the temperature near the corresponding return air inlet in controlled indoor is too high; Therefore, the air-out volume of air outlet corresponding to this return air inlet should be increased, to reduce the environment temperature near this return air inlet, make it be tending towards described indoor environment temperature T
in.
S327, keep the current air-out volume of described air outlet constant.
As △ T
-≤ △ T≤△ T
+time, illustrate that the air-out volume of the air outlet that corresponding return air inlet is corresponding meets demand for control, the environment temperature near corresponding return air inlet can be made to remain on described indoor environment temperature T
innear.
For the return air temperature of arbitrary return air inlet, respectively the air-out volume of each air outlet is regulated by step S322 ~ S326, make the return air temperature of corresponding return air inlet all be tending towards described indoor environment temperature T
in, thus achieve temperature field Balance route.
