Setting value.
Specifically：
(31) as Twp >=Tws+ δ t, average return air temperature is higher, and whole computer room is refrigeration direction demand, host computer control
Refrigeration direction demand is issued to each start air conditioner by plate, and each air conditioner of starting shooting is according to respective return air temperature and target temperature
The comparative result for spending setting value Tws determines carrying out practically state.
If Twi>=Tws+ δ t, illustrate that the return air temperature of i-th start air conditioner is higher, then i-th start air conditioner refrigeration
Operation.
If Tws- δ t ＜ Twi＜ Tws+ δ t, illustrate the return air temperature of i-th start air conditioner in the reasonable scope, then i-th
Platform start air conditioner air-supply operation.
If Twi≤ Tws- δ t, illustrate that the return air temperature of i-th start air conditioner is relatively low, then i-th start air conditioner air-supply
Operation, forbids the air conditioner heat-production to run, and prevents the refrigeration direction demand anomalous mode formula that the air conditioner is issued with host control panel from transporting
OK, avoid causing energy waste.
I.e. as Twp >=Tws+ δ t, average return air temperature is higher, and whole computer room is refrigeration direction demand, i.e. air-conditioning system
Big traffic direction is refrigerating operaton；Each start air conditioner can be transported according to respective return air temperature with refrigerating operaton or air-supply
OK, but heating operation is unable to, avoids different mode operation from causing energy waste.
In the present embodiment, refrigeration and heating be anomalous mode formula, and dehumidifying is anomalous mode formula with humidification, are blown and refrigerating/heating/remove
Wet/humidification is not anomalous mode formula.
(32) as Tws- δ t ＜ Twp ＜ Tws+ δ t, average return air temperature is reasonable, and whole computer room is air supply direction demand,
Air supply direction demand is issued to each start air conditioner by host control panel, and each air conditioner of starting shooting is according to respective return air temperature
Carrying out practically state is determined with the comparative result of target temperature setting value Tws.
If Twi>=Tws+ δ t, illustrate that the return air temperature of i-th start air conditioner is higher, then i-th start air conditioner refrigeration
Operation.
If Tws- δ t ＜ Twi＜ Tws+ δ t, illustrate the return air temperature of i-th start air conditioner in the reasonable scope, then i-th
Platform start air conditioner air-supply operation.
If Twi≤ Tws- δ t, illustrate that the return air temperature of i-th start air conditioner is relatively low, then i-th start air conditioner heat-production
Operation.
I.e. as Tws- δ t ＜ Twp ＜ Tws+ δ t, average return air temperature is reasonable, and whole computer room is air supply direction demand, i.e.,
The big traffic direction of air-conditioning system runs for air-supply；Each start air conditioner according to respective return air temperature, can with refrigerating operaton,
Heating operation or air-supply operation, there is no different mode operation.
(33) as Twp≤Tws- δ t, average return air temperature is relatively low, and whole computer room is to heat direction demand, host computer control
Plate is issued to each start air conditioner by direction demand is heated, and each air conditioner of starting shooting is according to respective return air temperature and target temperature
The comparative result for spending setting value Tws determines carrying out practically state.
If Twi>=Tws+ δ t, illustrate that the return air temperature of i-th start air conditioner is higher, then i-th start air conditioner air-supply
Operation, forbids the air conditioner refrigerating operaton, prevents the heating direction demand anomalous mode formula that the air conditioner is issued with host control panel from transporting
OK, avoid causing energy waste.
If Tws- δ t ＜ Twi＜ Tws+ δ t, illustrate the return air temperature of i-th start air conditioner in the reasonable scope, then i-th
Platform start air conditioner air-supply operation.
If Twi≤ Tws- δ t, illustrate that the return air temperature of i-th start air conditioner is relatively low, then i-th start air conditioner heat-production
Operation.
I.e. as Twp≤Tws- δ t, average return air temperature is relatively low, and whole computer room is heating direction demand, i.e. air-conditioning system
Big traffic direction is heating operation；Each start air conditioner can be transported according to respective return air temperature with heating operation or air-supply
OK, but refrigerating operaton is unable to, avoids different mode operation from causing energy waste.
δ t are temperature control precision value.In the present embodiment, the value range of δ t is 1~5, has both avoided value is excessive from causing
Air conditioner it is insensitive to refrigerating/heating demand, it is impossible to meet the refrigerating/heating demand of computer room in time；Avoid value too small again
Caused air conditioner is excessively sensitive to refrigerating/heating demand, causes frequent transitions operational mode, influences the service life of air conditioner.
In the value range, it both ensure that air conditioner can flexibly respond the refrigerating/heating demand of computer room, and in turn ensure that air conditioner just
Often operation.The specific value of δ t can be adjusted according to the actual requirements.
The computer-room air conditioning system control method of the present embodiment, time of every start air conditioner is obtained every the first setting time
Air temperature, and average return air temperature is calculated, then compared with target temperature setting value, determine air-conditioning system overall operation direction；
Then every start more respective return air temperature of air conditioner and average return air temperature, determine carrying out practically state, eliminate computer room
Interior hot localised points, reach temperature equalization in computer room；If air-conditioning system overall operation direction is run for air-supply, start air conditioner can
Think refrigeration, heating or air-supply operation；If air-conditioning system overall operation direction is refrigerating operaton, start air conditioner can be system
Cold operation or air-supply operation, forbid heating operation；If air-conditioning system overall operation direction is heating operation, start air conditioner can
Think heating operation or air-supply operation, forbid refrigerating operaton；Air conditioner is avoided to be transported with air-conditioning system overall operation direction anomalous mode formula
OK, energy waste caused by avoiding different mode operation so that whole computer room progressivelyes reach rational temperature range, keeps in computer room
The stability of temperature, the running environment of stabilization is provided for the electronic equipment in computer room.
Since each period use intensity of electronic equipment in computer room is different, high intensity service stage inner electronic equipment hair
The heat short time increases sharply, and causes room temperature to rise sharply；Standby time at night section inner electronic equipment caloric value it is few, air-conditioning system still with
Original state operating causes energy waste.For this situation, in order to ensure constant temperature in computer room, while again energy-efficient, control method
Further include following step：
(1) obtain this Twp calculated and calculate being averaged for (every the calculating of the first setting time once) with the last time
The difference DELTA Twp of return air temperature.
(2) if Twp >=Tws+ δ t, the setting temperature difference of and Δ Twp >=first, the first setting temperature difference ＞ 0；Illustrate freezing
Under the demand of direction, average return air temperature is still rising, then increases an air conditioner refrigerating operaton for being in holding state.
If Twp≤Tws- δ t, and Δ Twp≤second sets temperature difference, the second setting temperature difference ＜ 0；Illustrate in heating side
To under demand, average return air temperature is still declining, then increases an air conditioner heat-production in holding state and run.
If Tws- δ t/2 ＜ Twp ＜ Tws+ δ t/2, illustrate that average return air temperature is in zone of reasonableness, then control all increasings
The air conditioner opened is standby.
That is, according to the change of average return air temperature and average return air temperature, standby air conditioner is controlled to increase refrigeration temporarily
Or heating operation, with tackle thermic load in computer room rise sharply or rapid drawdown；When the average return air temperature in computer room returns to reasonable model
Enclose, that is, when meeting Tws- δ t/2 ＜ Twp ＜ Tws+ δ t/2, control the air conditioner increased temporarily standby；Realize quick response machine
The change of temperature in room, avoids in computer room temperature from rising sharply or rapid drawdown, ensures the stability of temperature in computer room.
First sets temperature difference as 1, i.e. determines that temperature rises sharply in computer room when the increment of average return air temperature is 1；Selection
The value, both avoided due to value it is excessive caused by can not timely respond to rising sharply for temperature in computer room, do not increase air conditioner in time
Refrigeration influences the normal operation of equipment in computer room；Avoid again due to value it is too small caused by the excessively sensitivity of temperature in computer room is caused
Standby air conditioner refrigeration is frequently increased temporarily, influences the service life of air conditioner.
Second sets temperature difference as -1, i.e. determines temperature decrease in computer room when the depreciation of average return air temperature is 1；Choosing
The value is selected, has both avoided, due to the excessive caused rapid drawdown that can not timely respond to temperature in computer room of value, not increasing air-conditioning in time
Device heating influences the normal operation of equipment in computer room；Avoid again due to value it is too small caused by the excessively sensitivity of temperature in computer room is made
Into standby air conditioner heat-production is frequently increased temporarily, the service life of air conditioner is influenced.
For example, the temperature control needs for being 10 air conditioners, can meeting whole computer room under normal circumstances now on duty by turns.
When workload abruptly increase in some server rush hour section in computer room, caloric value exceeds conventional level, 10 air conditioner refrigeration
Operation is also unable to reach cooling demand, then needs the standby air conditioner refrigeration of the addition on the basis of 10 air conditioners one by one
Operation, until average return air temperature recovers zone of reasonableness.
For example, calculate a Twp, Δ Twp within (10 minutes) every the first setting time.
If Twp >=Tws+ δ t and Δ Twp >=1, one air conditioner in holding state of superposition opens refrigerating operaton；10
After minute, if still Twp >=Tws+ δ t and Δ Twp >=1, second air conditioner in holding state of superposition opens refrigeration fortune
OK；And so on, until Tws- δ t/2 ＜ Twp ＜ Tws+ δ t/2, control the air conditioner of all superpositions to switch to holding state.
If Twp≤Tws- δ t and Δ Twp≤- 1, one air conditioner in holding state of superposition opens heating operation；
After ten minutes, if still Twp≤Tws- δ t and Δ Twp≤- 1, second air conditioner in holding state of superposition opens heating
Operation；And so on, until Tws- δ t/2 ＜ Twp ＜ Tws+ δ t/2, control the air conditioner of all superpositions to switch to holding state.
Step S4：The operation of every start air conditioner is controlled according to average return air humidity Tsp, target humidity setting value Tss.
Host control panel obtains the return air humidity of each start air conditioner, and calculates average return air humidity, is returned according to average
The operation of every wind moisture, target humidity set value calculation start air conditioner.Whole air-conditioning system has unified target humidity
Setting value.
Specifically：
(41) as Tsp >=Tss+ δ h, average return air humidity is higher, and whole computer room is dehumidifying direction demand, host computer control
Dehumidifying direction demand is issued to each start air conditioner by plate, and each air conditioner of starting shooting is wet according to respective return air humidity and target
The comparative result for spending setting value Tss determines carrying out practically state.
If Tsi>=Tss+ δ h, illustrate that the return air humidity of i-th start air conditioner is higher, then i-th start air conditioner dehumidifying
Operation.
If Tss- δ h ＜ Tsi＜ Tss+ δ h, illustrate the return air humidity of i-th start air conditioner in the reasonable scope, then i-th
Platform start air conditioner air-supply operation.
If Tsi≤ Tss- δ h, illustrate that the return air humidity of i-th start air conditioner is relatively low, then i-th start air conditioner air-supply
Operation, forbids air conditioner humidification operation, prevents the dehumidifying direction demand anomalous mode formula that the air conditioner is issued with host control panel from transporting
OK, avoid causing energy waste.
I.e. as Tsp >=Tss+ δ h, average return air humidity is higher, and whole computer room is dehumidifying direction demand, i.e. air-conditioning system
Big traffic direction runs for dehumidifying；Each start air conditioner is according to respective return air humidity, and can dehumidify operation or air-supply fortune
OK, but operation cannot be humidified, avoids different mode operation from causing energy waste.
(42) as Tss- δ h ＜ Tsp ＜ Tss+ δ h, average return air humidity is reasonable, and whole computer room is air supply direction demand,
Air supply direction demand is issued to each start air conditioner by host control panel, and each air conditioner of starting shooting is according to respective return air humidity
Carrying out practically state is determined with the comparative result of target humidity setting value Tss.
If Tsi>=Tss+ δ h, illustrate that the return air humidity of i-th start air conditioner is higher, then i-th start air conditioner dehumidifying
Operation.
If Tss- δ h ＜ Tsi＜ Tss+ δ h, illustrate the return air humidity of i-th start air conditioner in the reasonable scope, then i-th
Platform start air conditioner air-supply operation.
If Tsi≤ Tss- δ h, illustrate that the return air humidity of i-th start air conditioner is relatively low, then i-th start air conditioner humidification
Operation.
I.e. as Tss- δ h ＜ Tsp ＜ Tss+ δ h, average return air humidity is reasonable, and whole computer room is air supply direction demand, i.e.,
The big traffic direction of air-conditioning system runs for air-supply；Air conditioner each start shooting according to respective return air humidity, the operation that can dehumidify,
Humidification operation or air-supply operation, there is no different mode operation.

OK, energy waste caused by avoiding different mode operation so that whole computer room progressivelyes reach rational humidity range, keeps in computer room
The stability of humidity, the running environment of stabilization is provided for the electronic equipment in computer room.
Since computer room inner electronic equipment is there are high intensity service stage and idle stage, the humidity in computer room is caused to exist rapid
The situation with rapid drawdown is risen, if air-conditioning system is still operated with original state, be easy to cause energy waste, and can not keep permanent in computer room
It is wet.For this situation, in order to ensure constant humidity in computer room, and meanwhile it is again energy-efficient, control method further includes following step：
(1) obtain this Tsp calculated and calculate being averaged for (every the calculating of the first setting time once) with the last time
The difference DELTA Tsp of return air humidity.
(2) if Tsp >=Tss+ δ h, the wet difference of setting of and Δ Tsp >=first, the first wet difference ＞ 0 of setting；Illustrate dehumidifying
Under the demand of direction, average return air humidity is still rising, then increases an air conditioner dehumidifying operation in holding state.
If Tsp≤Tss- δ h, and Δ Tsp≤second sets wet difference, the second wet difference ＜ 0 of setting；Illustrate in humidification side
To under demand, average return air humidity is still declining, then increases an air conditioner humidification operation in holding state.
If Tss- δ h/2 ＜ Tsp ＜ Tss+ δ h/2, illustrate that average return air humidity is in zone of reasonableness, then control all increasings
The air conditioner opened is standby.
That is, according to the change of average return air humidity and average return air humidity, standby air conditioner is controlled to increase dehumidifying temporarily
Or humidification operation, with tackle humidity in computer room rise sharply or rapid drawdown；When the average return air humidity in computer room returns to zone of reasonableness,
When meeting Tss- δ h/2 ＜ Tsp ＜ Tss+ δ h/2, control the air conditioner increased temporarily standby；Realize in quick response computer room
The change of humidity, avoids in computer room humidity from rising sharply or rapid drawdown, ensures the stability of humidity in computer room.
First sets wet difference as 2, i.e. determines that humidity rises sharply in computer room when the increment of average return air humidity is 2；Selection
The value, both avoided due to value it is excessive caused by can not timely respond to rising sharply for humidity in computer room, do not increase air conditioner in time
Dehumidifying influences the normal operation of equipment in computer room；Avoid again due to value it is too small caused by the excessively sensitivity of humidity in computer room is caused
Standby air conditioner dehumidifying is frequently increased temporarily, influences the service life of air conditioner.
Second sets wet difference as -2, i.e. determines humidity rapid drawdown in computer room when the depreciation of average return air humidity is 2；Choosing
The value is selected, has both avoided, due to the excessive caused rapid drawdown that can not timely respond to humidity in computer room of value, not increasing air-conditioning in time
Device humidification influences the normal operation of equipment in computer room；Avoid again due to value it is too small caused by the excessively sensitivity of humidity in computer room is made
Into standby air conditioner humidification is frequently increased temporarily, the service life of air conditioner is influenced.
