Supply gas humidistat 112 from arithmetic unit 102 receiving target humidity Mt.In addition, humidistat 112 of supplying gas receives from moisture detector 58 of supplying gas the humidity M α that supplies gas.In addition, the deviation that humidistat 112 of supplying gas calculates target humidity Mt and supplies gas between humidity M α.And, to supply gas humidistat 112 based target humidity Mt and the deviation of supplying gas between humidity M α, as shown in Figure 4, what control heater 24 adds heat (as shown by the solid line), the flow (shown in dotted line) of spray water of humidity adjusting device 20 or the aperture (as indicated by chain dotted lines) of cooling water regulating valve 42.Thus, humidistat 112 of the supplying gas humidity M α that carries out regulating making supplying gas follows target humidity Mt.In addition, humidistat 112 of supplying gas also can be such as made up of PID adjusting apparatus.
Humidistat 112 based target humidity Mt and the deviation between humidity M α of supplying gas of supplying gas calculates output valve (0% ~ 100%).Further, humidistat 112 output valve of supplying gas exports to heater 24, pump 32 and cooling water regulating valve 42.Heater 24 is configured to, and when the output from humidistat 112 of supplying gas is 50% ~ 100%, controls to add heat.In addition, cooling water regulating valve 42 is configured to, and when the output from humidistat 112 of supplying gas is 25% ~ 50%, controls aperture.Pump 32 is configured in addition, under the output from humidistat 112 of supplying gas is 0% ~ 25% situation, controls rotating speed.
That is, humidistat 112 of supplying gas is configured to, when its export be greater than 50% and be less than or equal to 100%, control as exporting larger, heater 24 to add heat larger.In addition, humidistat 112 of supplying gas is configured to, and when its output is less than 50%, the aperture controlling the cooling water regulating valve 42 into exporting less then humidity adjusting device 20 is larger.In addition, when output (such as 25%) when exporting the aperture being less than cooling water regulating valve 42 and becoming maximum, the output carrying out controlling to make to supply gas humidistat 112 is less, then the flow of the spray water of humidity adjusting device 20 is larger.Because formation as noted above is supplied gas humidistat 112, so the humidity and temperature of supplying gas just can be adjusted without the need to arranging cooling device separately.In addition, in the present embodiment, the output when aperture of cooling water regulating valve 42 is maximum is 25%, but is not limited thereto, and also can be any output of 0 ~ 50%.
Humidistat 112 of supplying gas is configured to, and target humidity and the deviation of supplying gas between humidity M α adjust output accordingly.Such as, if target humidity Mt and the deviation of supplying gas between humidity M α are Δ M=Mt-M α, are then configured to deviation delta M larger, export larger.In addition, humidistat 112 of supplying gas also can be configured to, such as that deviation delta M is larger with the integrated value of time integral, exports larger.Here, humidistat 112 of supplying gas also can be set as, when Δ M=0, output is 50%.That is, what humidistat 112 of supplying gas was greater than 0 time control refrigerating/heating apparatus 24 at Δ M adds heat, the flow of the spray water of controlled humidity adjusting device 20 or control temperature when Δ M is less than 0.
Add heat selector 120 and be arranged on the thermoregulator 110 and supplying gas between humidistat 112 and heater 24 of supplying gas.Add heat selector 120 to be such as made up of high value selector.Add heat selector 120 receives them respectively output valve from supply gas thermoregulator 110 and humidistat 112 of supplying gas.Further, add the output that heat selector 120 selects to make the heating quantitative change high one of heater 24 from both output, and export to heater 24.
Traffic selector 122 is arranged on the thermoregulator 110 and supplying gas between humidistat 112 and pump 32 of supplying gas.Traffic selector 122 is such as made up of high value selector.Traffic selector 122 receives their output valve respectively from supply gas thermoregulator 110 and humidistat 112 of supplying gas.Further, Traffic selector 122 is selected to make the rotating speed of pump 32 uprise the output of one from both output, and exports to pump 32.In addition, output when Traffic selector 122 also can become maximum with the aperture of cooling water regulating valve 42 accordingly, is multiplied by the output valve of humidistat 112 of supplying gas.Such as, the output when the aperture of cooling water regulating valve 42 becomes maximum is 25%, the output valve of humidistat 112 of supplying gas also can be multiplied by 2(=50%/25% by Traffic selector 122), and use this output valve of 2 times to select.
Fig. 5 ~ Fig. 7 represents aircondition 1(particularly control device 100) in the flow chart of air conditioning control method.In addition, in the flow chart shown in Fig. 5 ~ Fig. 7, the order of operation (step) can suitably change, in addition, more than 1 in multiple operation (step) also can be omitted, and also can just start other operation before certain operation terminates in multiple operation (step).In addition, more than 2 of multiple operation (step) also can be made to perform simultaneously.
As shown in Figure 5, first, arithmetic unit 102 detects the temperature T α and the humidity M α (S10) that supplies gas that supplies gas.Specifically, arithmetic unit 102 receives the temperature T α that supplies gas detected by temperature detector 56 of supplying gas.In addition, arithmetic unit 102 receives the humidity M α that supplies gas detected by moisture detector 58 of supplying gas.
Then, arithmetic unit 102 judges whether the humidity M α that supplies gas is less than target lower end humidity Ma(S100).When the humidity M α that is judged as supplying gas is less than target lower end humidity Ma (S100 is "Yes"), impact point t is set in target lower extreme point a(S102 by arithmetic unit 102).That is, target temperature Tt is set in target lower temperature Ta by arithmetic unit 102, target humidity Mt is set in target lower end humidity Ma.Further, arithmetic unit 102 is by target temperature Tt(target lower temperature Ta) to supplying gas, thermoregulator 110 exports, by target humidity Mt(target lower end humidity Ma) to supplying gas, humidistat 112 exports.
Now, because the humidity M α that supplies gas is target upper end below humidity Mc, so arithmetic unit 102 controls switching part 26, it is made stream to be switched to leading portion heater 12 side (S104).Thus, the hot-air that adds carrying out self-heating apparatus 24 is supplied to leading portion heater 12.
Then, humidistat 112 of supplying gas carries out humidification control (S106).Specifically, now, because the humidity M α that supplies gas is lower than target lower end humidity Ma, thus humidistat 112 of supplying gas control heater 24 add heat.More particularly, due to deviation delta M(=Ma-M α) symbol be just, so the output valve being greater than 50% sends to heater 24 by humidistat 112 of supplying gas.Now, humidistat 112 of supplying gas also can be as noted above, increases output valve accordingly with the absolute value of deviation delta M.What control heater 24 thus adds heat.
Then, thermoregulator 110 of supplying gas judges whether to supply gas temperature T α lower than target lower temperature Ta(S110).Specifically, the temperature T α that supplies gas detected by temperature detector 56 of supplying gas compares with the target lower temperature Ta being set to target temperature Tt by thermoregulator 110 of supplying gas.Further, thermoregulator 110 of supplying gas judges whether to supply gas temperature T α lower than target lower temperature Ta.
When being judged as supplying gas temperature T α lower than (S110 is "Yes") when target lower temperature Ta, thermoregulator 110 of supplying gas carries out computer heating control (S112).After S112 operation, flow process returns the operation of S10.Specifically, what thermoregulator 110 of supplying gas controlled heater 24 adds heat.More particularly, due to deviation delta T(=Ta-T α) symbol be just, so the output valve being greater than 50% sends to heater 24 by thermoregulator 110 of supplying gas.Now, thermoregulator 110 of supplying gas also can be as noted above, increases output valve accordingly with the absolute value of deviation delta T.What control heater 24 thus adds heat.
In addition, now, from supply gas thermoregulator 110 and both humidistats 112 of supplying gas, the output valve being greater than 50% is sent to heater 24.Thus, as noted above, add heat selector 120 from both output, select the output making the heating quantitative change of heater 24 high, and export to heater 24.
On the other hand, when being judged as supplying gas temperature T α and being not less than target lower temperature Ta (S110 is "No"), thermoregulator 110 of supplying gas judges whether the temperature T α that supplies gas is greater than target lower temperature Ta(S114).When the temperature T α that is judged as supplying gas is greater than target lower temperature Ta (S114 is "Yes"), thermoregulator 110 of supplying gas carries out cooling and controls (S116).After S116 operation, flow process returns the operation of S10.
Specifically, to supply gas the flow of spray water of thermoregulator 110 controlled humidity adjusting device 20.More particularly, due to deviation delta T(=Ta-T α) symbol be negative, so the output valve being less than 50% sends to pump 32 by thermoregulator 110 of supplying gas.Now, thermoregulator 110 of supplying gas also can be as noted above, reduces output valve accordingly with the absolute value of deviation delta T.That is, supplying gas thermoregulator 110 also can larger along with the absolute value of deviation delta T (T α be larger) and make output valve more close to 0%.Thus, the rotating speed of control pump 32 and the flow of the spray water of controlled humidity adjusting device 20.
In addition, by the temperature T α and target temperature Tt(target lower temperature Ta that supplies gas in the operation of S110 and S114) when comparing, supply gas thermoregulator 110 when the temperature T α that supplies gas is (about such as ± 1 degree) near target lower temperature Ta, and the temperature T α that also can be judged to supply gas is consistent with target lower temperature Ta.This situation is also identical in other operation of following explanation.
On the other hand, when the temperature T α that is judged as supplying gas is not more than target lower temperature Ta (S114 is "No"), the temperature T α that supplies gas is consistent with target lower temperature Ta.Now, control device 100 judge to supply gas humidity M α whether with target lower end humidity Ma(target humidity Mt) consistent (S120).Specifically, humidistat 112 of the supplying gas humidity M α that will supply gas compares with target lower end humidity Ma and judges whether both consistent.Now, supply gas humidistat 112 when the humidity M α that supplies gas arrives (about such as ± 1 degree) near the humidity Ma of target lower end, the humidity M α that also can be judged as supplying gas is consistent with target lower end humidity Ma.This situation is also identical in other operation of following explanation.When the humidity M α that supplies gas is not consistent with target lower end humidity Ma (S120 is "No"), flow process returns the operation of S10.
On the other hand, when the humidity M α that supplies gas is consistent with target lower end humidity Ma (S120 is "Yes"), supply gas thermoregulator 110 and humidistat 112 of supplying gas to make state point α (the T α that supplies gas, M α) can not leave impact point t(target lower extreme point a) near mode, output is finely tuned (S130).Specifically, now, the humidity M α that makes to supply gas is consistent with target lower end humidity Ma, and the temperature T α that makes to supply gas is consistent with target lower temperature Ta.Thus, thermoregulator 110 of supplying gas can not leave mode near target lower temperature Ta with the temperature T α that makes to supply gas, and finely tunes output.In the same manner, humidistat 112 of supplying gas can not leave mode near the humidity Ma of target lower end with the humidity M α that makes to supply gas, and finely tunes output.
Such as, during S130 operation, the temperature T α that supplies gas leaves from the direction reduced to temperature near target lower temperature Ta, thermoregulator 110 of supplying gas controls, make output close to 50% and the flow of the spray water of minimizing humidity adjusting device 20, to make to supply gas temperature T α close to target lower temperature Ta.In addition, such as during the process of S130, when supply gas humidity M α near the humidity Ma of target lower end to humidity become large direction leave, humidistat 112 of supplying gas controls, make output close to 50% and reduce heater 24 add heat, to make to supply gas humidity M α close to target lower end humidity Ma.
On the other hand, in the operation of S100, when the humidity M α that is judged as supplying gas is not less than target lower end humidity Ma (S100 is "No"), namely when M α≤Ma, as shown in Figure 6, arithmetic unit 102 judges whether the humidity M α that supplies gas is greater than target upper end humidity Mc(S200).When the humidity M α that is judged as supplying gas is not more than target upper end humidity Mc (S200 is "No"), namely when Ma≤M α≤Mc, the point that humidity on aim curve L is M α by arithmetic unit 102 is set as impact point t(S202).That is, target humidity Mt is set as M α by arithmetic unit 102.In addition, target temperature Tt is set as that the humidity on aim curve L is the temperature of M α by arithmetic unit 102.
Now, because the humidity M α that supplies gas is target upper end below humidity Mc, so arithmetic unit 102 controls switching part 26 switch to leading portion heater 12 side (S204) to make its stream.Thus, the hot-air that adds carrying out self-heating apparatus 24 is supplied to leading portion heater 12.
Then, undertaken controlling (S206) by humidistat 112 of supplying gas.Here, now, because the humidity M α that supplies gas is equal with target humidity Mt, so deviation delta M(=Mt-M α) be 0.Thus, from humidistat 112 of supplying gas, the output valve of 50% is sent to each machine.That is, when Ma≤M α≤Mc, humidistat 112 of supplying gas does not carry out humidity regulation control.In addition, control owing to not carrying out humidity regulation by humidistat 112 of supplying gas, so when Ma≤M α≤Mc, the humidistat 112 that also can be configured to supply gas does not export.
Then, thermoregulator 110 of supplying gas judges whether to supply gas temperature T α lower than target temperature Tt(S210).Specifically, the temperature T α and target temperature Tt that supplies gas detected by temperature detector 56 of supplying gas compares by thermoregulator 110 of supplying gas.Further, thermoregulator 110 of supplying gas judges whether to supply gas temperature T α lower than target temperature Tt.
When being judged as supplying gas temperature T α lower than (S210 is "Yes") when target temperature Tt, thermoregulator 110 of supplying gas carries out computer heating control (S212).After S212 operation, flow process returns the operation of S10.Specifically, what thermoregulator 110 of supplying gas controlled heater 24 adds heat.More particularly, thermoregulator 110 of supplying gas is due to deviation delta T(=Tt-T α) symbol for just, so export the output valve being greater than 50% to heater 24.Now, thermoregulator 110 of supplying gas is as noted above, also can with the absolute value of deviation delta T accordingly, increase output valve.Thus, what control heater 24 adds heat.
On the other hand, when the temperature T α that is judged as supplying gas is not less than target temperature Tt (S210 is "No"), whether thermoregulator 110 of the supplying gas temperature T α that judges to supply gas is greater than target temperature Tt(S214).When the temperature T α that is judged as supplying gas is greater than target temperature Tt (S214 is "Yes"), thermoregulator 110 of supplying gas carries out cooling and controls (S216).After S216 operation, flow process returns the operation of S10.
Specifically, to supply gas the flow of spray water of thermoregulator 110 controlled humidity adjusting device 20.More particularly, due to deviation delta T(=Ta-T α) symbol be negative, so the output valve being less than 50% sends to pump 32 by thermoregulator 110 of supplying gas.Now, thermoregulator 110 of supplying gas also can be as noted above, reduces output valve accordingly with the absolute value of deviation delta T.That is, supplying gas thermoregulator 110 also can larger along with the absolute value of deviation delta T (T α be larger) and make output valve more close to 0%.Thus, the rotating speed of control pump 32 and the flow of the spray water of controlled humidity adjusting device 20.
On the other hand, when the temperature T α that is judged as supplying gas is not more than target temperature Tt (S214 is "No"), the temperature T α that supplies gas is consistent with target temperature Tt.In addition, in the operation of S210 and S214 by supply gas between temperature T α and target temperature Tt relatively in, supply gas thermoregulator 110 when the temperature T α that supplies gas is positioned at (about such as ± 1 degree) near target lower temperature Ta, and the temperature T α that also can be judged as supplying gas is consistent with target lower temperature Ta.
Now, as noted above, the humidity M α that supplies gas is equal with target humidity Mt.Thus, supply gas thermoregulator 110 and humidistat 112 of supplying gas can not leave mode near impact point t with the state point α (T α, M α) that makes to supply gas, and finely tune (S230) output.Specifically, thermoregulator 110 of supplying gas can not leave mode near target temperature Tt with the temperature T α that makes to supply gas, and finely tunes output.In the same manner, humidistat 112 of supplying gas can not leave mode near the humidity Ma of target lower end with the humidity M α that makes to supply gas, and finely tunes output.
On the other hand, in the operation of S200, when the humidity M α that is judged as supplying gas is greater than target upper end humidity Mc (S200 is "Yes"), as shown in Figure 7, impact point t is set as target upper extreme point c(S302 by arithmetic unit 102).That is, target temperature Tt is set as target upper end temperature Tc by arithmetic unit 102, target humidity Mt is set as target upper end humidity Mc.
Now, because the humidity M α that supplies gas is greater than target upper end humidity Mc, so arithmetic unit 102 controls switching part 26, switch to back segment heater 14 side (S304) to make its stream.Thus, the hot-air that adds carrying out self-heating apparatus 24 is supplied to back segment heater 14.
Then, humidistat 112 of supplying gas carries out Dehumidification controlling (S306).Specifically, now, because the humidity M α that supplies gas is higher than target upper end humidity Mc, so the flow of the supply gas aperture of humidistat 112 controlled cooling model water regulating valve 42 and the spray water of humidity adjusting device 20.More particularly, due to deviation delta M(=Mc-M α) symbol be negative, so the output valve being less than 50% sends to cooling water regulating valve 42 and pump 32 by humidistat 112 of supplying gas.Now, humidistat 112 of supplying gas also can be as noted above, increases output valve accordingly with the absolute value of deviation delta M.Here, when the output valve from humidistat 112 of supplying gas is 25% ~ 50%, the aperture of controlled cooling model water regulating valve 42.In addition, exist; When output valve from humidistat 112 of supplying gas is 0% ~ 25%, suppress the flow of the rotating speed of pump 32 and the spray water of humidity adjusting device 20.Thus, the flow of the spray water of controlled humidity adjusting device 20 and temperature.
Then, thermoregulator 110 of supplying gas judges whether to supply gas temperature T α lower than target upper end temperature Tc(S310).Specifically, the temperature T α that supplies gas detected by temperature detector 56 of supplying gas compares with the target upper end temperature Tc being set to target temperature Tt by thermoregulator 110 of supplying gas.Further, thermoregulator 110 of supplying gas judges whether to supply gas temperature T α lower than target upper end temperature Tc.
When being judged as supplying gas temperature T α lower than (S310 is "Yes") when target lower temperature Ta, thermoregulator 110 of supplying gas carries out computer heating control (S312).After S312 operation, flow process returns the operation of S10.Specifically, what thermoregulator 110 of supplying gas controlled heater 24 adds heat.More particularly, due to deviation delta T(=Tc-T α) symbol be just, so the output valve being greater than 50% sends to heater 24 by thermoregulator 110 of supplying gas.Now, thermoregulator 110 of supplying gas also can be as noted above, increases output valve accordingly with the absolute value of deviation delta T.What control heater 24 thus adds heat.
On the other hand, when the temperature T α that is judged as supplying gas is not less than target upper end temperature Tc (S310 is "No"), whether thermoregulator 110 of the supplying gas temperature T α that judges to supply gas is greater than target upper end temperature Tc(S314).When the temperature T α that is judged as supplying gas is greater than target upper end temperature Tc (S314 is "Yes"), thermoregulator 110 of supplying gas carries out cooling and controls (S116).After S116 operation, flow process returns the operation of S10.
Specifically, to supply gas the flow of spray water of thermoregulator 110 controlled humidity adjusting device 20.More particularly, due to deviation delta T(=Tc-T α) symbol be negative, so the output valve being less than 50% sends to pump 32 by thermoregulator 110 of supplying gas.Now, thermoregulator 110 of supplying gas also can be as noted above, reduces output valve accordingly with the absolute value of deviation delta T.That is, supplying gas thermoregulator 110 also can larger along with the absolute value of deviation delta T (T α be larger) and make output valve more close to 0%.Thus, the rotating speed of control pump 32 and the flow of the spray water of controlled humidity adjusting device 20.
In addition, now, from supply gas thermoregulator 110 and both humidistats 112 of supplying gas, the output valve being less than 50% is sent to pump 32.Thus, as noted above, Traffic selector 122 selects the rotating speed of pump 32 to uprise the output of one from both output, and exports to pump 32.
In addition, by the temperature T α and target temperature Tt(target upper end temperature Tc that supplies gas in the operation of S310 and S314) when comparing, supply gas thermoregulator 110 when the temperature T α that supplies gas is (about such as ± 1 degree) near the temperature Tc of target upper end, and the temperature T α that also can be judged to supply gas is consistent with target upper end temperature Tc.
On the other hand, when the temperature T α that is judged as supplying gas is not less than target upper end temperature Tc (S314 is "No"), the temperature T α that supplies gas is consistent with target upper end temperature Tc.Now, control device 100 judge to supply gas humidity M α whether with target upper end humidity Mc(target humidity Mt) consistent (S320).Specifically, humidistat 112 of the supplying gas humidity M α that will supply gas compares with target upper end humidity Mc and judges whether both consistent.Now, supply gas humidistat 112 when the humidity M α that supplies gas arrives (about such as ± 1 degree) near the humidity Mc of target upper end, the humidity M α that also can be judged as supplying gas is consistent with target upper end humidity Mc.When the humidity M α that supplies gas is not consistent with target upper end humidity Mc (S320 is no), flow process returns the operation of S10.
On the other hand, when the humidity M α that supplies gas is consistent with target upper end humidity Mc (S320 is "Yes"), supply gas thermoregulator 110 and humidistat 112 of supplying gas to make state point α (the T α that supplies gas, M α) impact point t(target upper extreme point c can not be left) near mode, output is finely tuned (S330).Specifically, now, the humidity M α that makes to supply gas is consistent with target upper end humidity Mc, and the temperature T α that makes to supply gas is consistent with target upper end temperature Tc.Thus, thermoregulator 110 of supplying gas can not leave mode near the temperature Tc of target upper end with the temperature T α that makes to supply gas, and finely tunes output.In the same manner, humidistat 112 of supplying gas can not leave mode near the humidity Mc of target upper end with the humidity M α that makes to supply gas, and finely tunes output.
Below, enumerate object lesson, the action that aircondition 1 is adjusted the temperature T α and the humidity M α that supplies gas that supplies gas by above-mentioned air conditioning control method is described.Fig. 8 is for illustration of the figure of humidity M α lower than the action when humidity Ma of target lower end that supply gas.Illustrated in air hythergraph as shown in Figure 8, at state point α 1 place of supplying gas, the humidity M α that supplies gas is lower than target lower end humidity Ma.Thus, in the operation of the S102 shown in Fig. 5, impact point t is set as target lower extreme point a(Ta, Ma by arithmetic unit 102).In addition, the operation of the S104 according to Fig. 5, the hot-air that adds carrying out self-heating apparatus 24 is supplied to leading portion heater 12.
In addition, at state point α 1 place of supplying gas, the humidity M α that supplies gas is lower than target lower end humidity Ma.Thus, in the operation of the S106 shown in Fig. 5, humidistat 112 of supplying gas controls to add heat by being greater than the output valve of 50% to heater 24 transmission, thus carries out humidification control.In addition, at state point α 1 place of supplying gas, the temperature T α that supplies gas is lower than target lower temperature Ta.Thus, in the operation of the S112 shown in Fig. 5, thermoregulator 110 of supplying gas controls to add heat by being greater than the output valve of 50% to heater 24 transmission, thus carries out computer heating control.
Further, repeat the operation of S10 ~ S112 and as indicated by arrow a 1, the temperature T α that supplies gas rises, as supplied gas shown in state point α 2, the temperature T α that supplies gas is consistent with target lower temperature Ta.Now, because deviation delta T is 0, so the output of thermoregulator 110 of supplying gas is 50%.On the other hand, humidity M α is supplied gas lower than target lower end humidity Ma.Thus, return the operation of S10 from the operation of S120, in the operation of S106, humidistat 112 of supplying gas controls to add heat by being greater than the output valve of 50% to heater 24 transmission, thus carries out humidification control.Thus, as indicated by arrow a 2, the temperature T α that supplies gas becomes higher than target lower temperature Ta.
Thus, in the operation of the S116 of Fig. 5, thermoregulator 110 of supplying gas by sending the flow being less than the output valve of 50% and the spray water of controlled humidity adjusting device 20 to pump 32, thus carries out cooling control.That is, now, pump 32 action and humidity adjusting device 20 sprays spray water.Now, spray spray water by humidity adjusting device 20 and carry out heat insulation humidification.Like this, by repeating the flow of the operation of S10 ~ S116 and the spray water of controlled humidity adjusting device 20, control heater 24(leading portion heater 12) add heat, then the state point α that such as supplies gas shown in arrow A 3 ~ A5 follows target lower extreme point a.
Like this, when the humidity M α that supplies gas is lower than target lower end humidity Ma, the state point α that can make to supply gas follows impact point t(target lower extreme point a).In addition, before the state point α that supplies gas follows target lower extreme point a, when the humidity M α that supplies gas becomes target lower end more than humidity Ma, the flow process of air conditioning control method is "No" by making S100 be "No" and S200, and advances to the operation of the S202 shown in Fig. 6.Thus, although the humidity M α that supplies gas when starting is lower than target lower end humidity Ma, along with control operation carry out and the humidity M α that supplies gas is target lower end more than humidity Ma when, the method shown below state point α that makes to supply gas also can be utilized to follow impact point t.That is, change without the need to setting and state that is that should follow corresponding with extraneous gas condition and envisions line, the state point α that just can make to supply gas follows the impact point t on aim curve L.
Fig. 9 be for illustration of supply gas humidity M α between target lower end humidity Ma and target upper end humidity Mc the figure of action.Shown in showing in the warm and humid legend of the air of Fig. 9, at state point α 1(T α 1, the M α 1 that supplies gas) in, the humidity M α 1 that supplies gas is for target lower end more than humidity Ma and target upper end below humidity Mc.Thus, in the operation of the S202 shown in Fig. 6, the humidity that impact point t is set as on aim curve L by arithmetic unit 102 is some t1(Tt, the M α 1 of M α 1).In addition, by the operation of the S204 shown in Fig. 6, the hot-air that adds of self-heating apparatus 24 is supplied to leading portion heater 12 in the future.
Now, because the humidity M α 1 that supplies gas is equal with target humidity Mt, so deviation delta M(=Mt-M α 1) be 0.Thus, as noted above, humidistat 112 of supplying gas does not carry out humidity regulation control.In addition, in the example of figure 9, at state point α 1 place of supplying gas, the temperature T α 1 that supplies gas is higher than target temperature Tt.Thus, in the operation of the S216 shown in Fig. 6, thermoregulator 110 of supplying gas by sending the flow being less than the output valve of 50% and the spray water of controlled humidity adjusting device 20 to pump 32, thus carries out cooling control.
Now, spray spray water by humidity adjusting device 20 and carry out heat insulation humidification.Thus, supply gas state point α as shown in arrow B 1, be changed to state point α 2(T α 2, the M α 2 that supplies gas along isenthalp from the state point α 1 that supplies gas).Now, in the operation of S202, the humidity that impact point t is set as on aim curve L by arithmetic unit 102 is some t2(Tt, the M α 2 of M α 2).
Now, in the same manner, because the humidity M α 2 that supplies gas is equal with target humidity Mt, so deviation delta M(=Mt-M α 2) be 0.Thus, as noted above, humidistat 112 of supplying gas does not carry out humidity regulation control.In addition, at state point α 2 place of supplying gas, supply gas temperature T α 2 also higher than target temperature Tt.Thus, in the operation of the S216 shown in Fig. 6, thermoregulator 110 of supplying gas by sending the flow being less than the output valve of 50% and the spray water of controlled humidity adjusting device 20 to pump 32, thus carries out cooling control.Now, owing to carrying out heat insulation humidification in the same manner, so supply gas state point α as shown in arrow B 2, be changed to state point α 3(T α 3, the M α 3 that supplies gas along isenthalp from the state point α 2 that supplies gas).
Below, repeat the process of S10 ~ S216 in the same manner, thus as shown in arrow B 3, the state point α that supplies gas follows the impact point t4 on aim curve L.Like this, when the humidity M α that supplies gas be between target lower end humidity Ma and target upper end humidity Mc and the temperature T α that supplies gas higher than target temperature Tt, the state point α that can make to supply gas follows impact point t.
In addition, before the state point α that supplies gas follows impact point t, when the humidity M α that supplies gas becomes higher than target upper end humidity Mc, the flow process of air conditioning control method due to S100 for "No" and S200 to advance to the operation of the S302 shown in Fig. 7 for "Yes".Thus, even if the humidity M α that supplies gas when starting is target upper end below humidity Mc but carries out supplying gas humidity M α higher than target upper end humidity Mc along with control operation, the state point α that also can make to supply gas follows impact point t.That is, change without the need to setting and state that is that should follow corresponding with extraneous gas condition and envisions line, the state point α that just can make to supply gas follows the impact point t on aim curve L.
Figure 10 be for illustration of supply gas humidity M α between target lower end humidity Ma and target upper end humidity Mc the figure of action.As illustrated in the air hythergraph of Figure 10, in the state point α that supplies gas (T α, M α), the humidity M α that supplies gas is target lower end more than humidity Ma and target upper end below humidity Mc.Thus, identically with the example of Fig. 9, in the operation of the S202 shown in Fig. 6, the humidity that impact point t is set as on aim curve L by arithmetic unit 102 is some t(Tt, the M α of M α).In addition, by the operation of the S204 shown in Fig. 6, the hot-air that adds of self-heating apparatus 24 is supplied to leading portion heater 12 in the future.In addition, as noted above, arithmetic unit 102 also can control switching part 26 and in the future self-heating apparatus 24 add hot-air backward section heater 14 supply.
Now, because the humidity M α that supplies gas is equal with target humidity Mt, so deviation delta M(=Mt-M α) be 0.Thus, as noted above, humidistat 112 of supplying gas does not carry out humidity regulation control.In addition, in the example of Figure 10, at state point α place of supplying gas, the temperature T α that supplies gas is lower than target temperature Tt.Thus, in the operation of the S216 shown in Fig. 6, the thermoregulator 110 of supplying gas by sending the output valve being greater than 50% and the heat that adds controlling heater 24 to heater 24, thus carries out computer heating control.
Below, by repeating S10 ~ S212 operation, the state point α that supplies gas follows the impact point t on aim curve L.Like this, when supply gas humidity M α between target lower end humidity Ma and target upper end humidity Mc and the temperature T α that supplies gas lower than target temperature Tt, the state point α that can make to supply gas follows impact point t.That is, change without the need to setting and state that is that should follow corresponding with extraneous gas condition and envisions line, the state point α that just can make to supply gas follows the impact point t on aim curve L.
Figure 11 is for illustration of the figure of humidity M α higher than the action when humidity Mc of target upper end that supply gas.As illustrated in the air hythergraph of Figure 11, at state point α 1 place of supplying gas, the humidity M α that supplies gas is higher than target upper end humidity Mc.Thus, in the operation of the S302 shown in Fig. 7, impact point t is set as target upper extreme point c(Tc, Mc by arithmetic unit 102).In addition, by the operation of the S304 shown in Fig. 7, in the future self-heating apparatus 24 add hot-air backward section heater 14 supply.
In addition, at state point α 1 place of supplying gas, the humidity M α that supplies gas is higher than target upper end humidity Mc.Thus, in the operation of the S306 shown in Fig. 7, humidistat 112 of supplying gas sends the temperature being less than the output valve of 50% and the spray water of controlled humidity adjusting device 20 to cooling water regulating valve 42, thus carries out Dehumidification controlling.In addition, at state point α 1 place of supplying gas, the temperature T α that supplies gas is higher than target upper end temperature Tc.Thus, in the operation of the S316 shown in Fig. 7, thermoregulator 110 of supplying gas sends the flow being less than the output valve of 50% and the spray water of controlled humidity adjusting device 20 to pump 32, thus carries out cooling control.
Here, as noted above, by the control of humidistat 112 of supplying gas, the aperture of adjustment cooling water regulating valve 42.That is, now, the temperature of the spray water of humidity adjusting device 20 reduces.Thus, repeat the operation of S10 ~ S316, as shown in arrow C 1, the temperature T α that supplies gas declines, and then the humidity M α that supplies gas also declines.Further, as supplied gas shown in state point α 2, the temperature T α that supplies gas is consistent with target upper end temperature Tc.Now, because deviation delta T is 0, so the output of thermoregulator 110 of supplying gas is 50%.On the other hand, the humidity M α that supplies gas maintains the state higher than target upper end humidity Mc.That is, maintaining deviation delta M is negative state.
Thus, in the operation of S306, humidistat 112 of supplying gas makes output valve be reduced to 25%.Now, as noted above, the output due to thermoregulator 110 of supplying gas is 50%, so humidity adjusting device 20 does not spray spray water.Thus, during the output valve of the humidistat 112 that makes to supply gas is from 50% to 25%, the humidity M α that supplies gas does not follow target upper end humidity Mc.Therefore, humidistat 112 of supplying gas sends to cooling water regulating valve 42 and pump 32 output valve being less than 25% further.Thus, become standard-sized sheet in the aperture of cooling water regulating valve 42, under the temperature of the spray water of humidity adjusting device 20 becomes minimum state, humidity adjusting device 20 sprays spray water.
Thus, the temperature T α that supplies gas becomes lower than target upper end temperature Tc.Thus, by the operation of S312, supply gas thermoregulator 110 to heater 24 send be greater than 50% output valve and control heater 24(back segment heater 14) add heat, thus carry out computer heating control.Like this, by repeating the flow of the operation of S10 ~ S312 and the spray water of controlled humidity adjusting device 20, control heater 24(back segment heater 14) add heat, thus such as shown in arrow C 2 ~ C3, the state point α that supplies gas follows target upper extreme point c.
Like this, when the humidity M α that supplies gas is higher than target upper end humidity Mc, the state point α that can make to supply gas follows impact point t(target upper extreme point c).In addition, before the state point α that supplies gas follows target upper extreme point c, when the humidity M α that supplies gas becomes target upper end below humidity Mc, the flow process of air conditioning control method due to S100 for "No" and S200 to advance to the operation of the S202 shown in Fig. 6 for "No".Thus, even if supply gas humidity M α higher than target upper end humidity Mc when starting, but along with control operation carry out and the humidity M α that supplies gas is target upper end below humidity Mc when, the state point α that also can make to supply gas follows impact point t.That is, change without the need to setting and state that is that should follow corresponding with extraneous gas condition and envisions line, the state point α that just can make to supply gas follows the impact point t on aim curve L.
As noted above, the aircondition 1 involved by present embodiment is configured to, and sets target temperature Tt and the target humidity Mt of the point on aim curve accordingly with the state of supplying gas.In addition, thermoregulator 110 of supplying gas is configured to as described below adjustment: based on the deviation of supplying gas between temperature T α and target temperature Tt, controls heater 24 and humidity adjusting device 20 at least wherein 1, and the temperature T α that makes to supply gas follows target temperature Tt.In addition, humidistat 112 of supplying gas is configured to as described below adjustment: based on the deviation of supplying gas between humidity M α and target humidity Mt, controls heater 24 and humidity adjusting device 20 at least wherein 1, and the humidity M α that makes to supply gas follows target humidity Mt.
Thus, in the present embodiment, as used as described in Fig. 8 ~ Figure 11 above, not monitoring the state of extraneous gas and only monitoring the temperature T α and the humidity M α that supplies gas that supplies gas, just can carrying out the control for adjusting supply gas temperature and humidity of supplying gas.Thus, due to without the need to carrying out the different controls corresponding from the state of extraneous gas, so inhibit the problem produced in above-mentioned Japanese Unexamined Patent Publication 11-83129.
In other words, in the present embodiment, state of no matter supplying gas why situation, all passes through the control of supply gas thermoregulator 110 and the humidistat 112 of supplying gas as shown in Fig. 5 ~ Fig. 7, and to heater 24 and humidity adjusting device 20 at least wherein 1 control.That is, in the present embodiment, be not pre-determine accordingly with extraneous gas state to control operation.In other words, in the present embodiment, change envision line without the need to setting and state that is that should follow corresponding with extraneous gas condition, the state point α that just can make to supply gas follows the impact point t on aim curve L.Thus, in the present embodiment, the simplification of the control for regulating supply gas temperature and humidity of supplying gas can be realized.
In addition, in the present embodiment, aircondition 1 is configured to, corresponding with the state of supplying gas and the point on aim curve L is set as impact point.That is, aircondition 1 is configured to the temperature of the point on aim curve L and humidity to be set as target temperature Tt and target humidity Mt respectively.Thus, the point of the most easily following from the state point α that supplies gas is set as impact point t.Thus, in the present embodiment, can control efficiently.
In addition, in the present embodiment, be configured to arrange leading portion heater 12 and back segment heater 14, heater 24 adds hot-air to leading portion heater 12 or back segment heater 14 supply.Thereby, it is possible to utilize the air before and after 1 heater, 24 pairs of humidity adjusting devices 20 to heat.Thereby, it is possible to shorten the device length of aircondition 1.
In addition, in the present embodiment, switching part 26 is set between heater 24 and leading portion heater 12 and back segment heater 14, consists of, corresponding with the state of supplying gas and switch heater 24 and supply to which of leading portion heater 12 and back segment heater 14 and add hot-air.Thereby, it is possible to the state of supplying gas accordingly, switch to the air (extraneous gas) before to humidity adjusting device 20 to heat, or to the air heat after humidity adjusting device 20.Thus, be no matter any one condition of supplying gas of Fig. 8 ~ Figure 11, the state point α that can make to supply gas follows impact point t.
In addition, the power output that also can be configured to back segment heater 14 is less than the power output of leading portion heater 12.According to said structure, when the condition of supplying gas is hot and humid as illustrated in Figure 11, only use back segment heater 14 without the need to using the heater of this high-output power of leading portion heater 12, the state point α that can make to supply gas follows impact point.Thus, particularly when the condition of supplying gas is hot and humid, the consumption of heat energy can be suppressed.
