That is, off-premises station mainboard 12 is by judging that the magnitude relationship between evaporating temperature Te and optimal evaporation temperature upper limit a and optimal evaporation lowest temperature b obtains the output size cases of off-premises station 10, when the output of off-premises station 10 is less than normal, off-premises station mainboard 12 makes the output of off-premises station 10 rise one grade, and then judge whether the output of now off-premises station 10 is positioned at optimum state, when the output of off-premises station 10 is still less than normal, then again one grade is risen to the output of off-premises station 10, and again judge, until reach optimum state.
When the output of off-premises station 10 is bigger than normal, off-premises station mainboard 12 makes the output of off-premises station 10 decline one grade, and then judge whether the output of now off-premises station 10 is positioned at optimum state, when the output of off-premises station 10 is still bigger than normal, then again one grade is declined to the output of off-premises station 10, and again judge, until reach optimum state; When off-premises station 10 exports in optimum state, the output of off-premises station 10 is not regulated.
When a and b is unequal, what air-conditioning system 100 can be stable exports within the scope of an optimum state, and decrease the adjustment number of times of off-premises station 10, air-conditioning system 100 is run more steady.Certainly, when not considering the stability of system, a and b can be same value, and the output of air-conditioning system 100 constantly can be fluctuated up and down in this value.
Suppose that air-conditioning system 100 is connected with four indoor sets 20, wherein, the indoor set 20 of unlatching has four.Be 8 degree with a below, b is 7 degree of runnings being example and being described in detail air-conditioning system 100.

Off-premises station mainboard 12 carries out logical calculated after receiving four inlet temperature T, obtains the mean value T of four inlet temperature T
on averagefor=(8+7+8+10)/4=8.25, and by bright for this mean value lamp the evaporating temperature Te replacing with indoor set 20, i.e. Te=8.25.Then Te and a and b is compared, due to 8.25 > 8, i.e. Te > a, off-premises station 10 exports needs rising one grade, after off-premises station 10 has upshiftd, detector unit 23 detects inlet temperature T again, after off-premises station mainboard 12 receives inlet temperature T, again carry out logical calculated, and compare with higher limit a and lower limit b.When Te is greater than a, then need again to make off-premises station 10 export rising one grade; When Te is less than b, then need to make off-premises station 10 export reduction by a grade; So repeatedly regulate, until b≤Te≤a, namely off-premises station 10 exports and reaches optimum state.
