Control device as the such air handling system 1 of control has: based on direct counter controller (the DDC:Direct Digital Controller) 20a～20c of the aperture of instrumentation output control valve 14a～14c of interior sensor 17a～17c; With based on from indoor 17a～17c, the various information sending water temperature sensor 18, obtain for gas sensor 19 and DDC20a～20c, the DDC21 of the running of control investigation mission outside the city or town machine 13 and the aperture of valve 16.
In Fig. 1, give identical label a～c to the identical associated components by conditioned space 11a～11c of correspondence again.
Here, cold beam 12a～12c have with the reference background technology in the equal structure of the cold beam 300 that illustrated of Figure 15, have heat exchanger 121a～121c and a pipeline 122a～122c.In so cold beam 12a～12c, the cold-producing medium that has been heat-treated is fed into heat exchanger 121a～121c from investigation mission outside the city or town machine 13, and the adjusting air that has been heat-treated is fed into pipeline 122a～122c from investigation mission outside the city or town machine 13.
Investigation mission outside the city or town machine 13 has: the heat(ing) coil 131 that the hot water HW that is supplied to by the heat power supply device from boiler etc. heats open-air; The cooling coil 132 that the cold water CW that is supplied to by the heat power supply device from cooling tower etc. cools off open-air; With will carry out the fan 133 that heat treated open-air (adjusting air) is sent by heat(ing) coil 131 or cooling coil 132.Here, pass through the hot water HW of heat(ing) coil 131 or cooling coil 132 and cold-producing medium that cold water CW consists of and be fed into heat exchanger 121a～121c of cold beam 12a～12c to circulate.Again, the adjusting air that is sent by fan 133 is fed into pipeline 122a～122c of cold beam 12a～12c.
Valve 14a～14c be arranged on connect investigation mission outside the city or town machine 13 and corresponding cold beam 12a～12c cold-producing medium with on the pipe arrangement 14, and the known flow control valve of amount of cold-producing medium that is flow into heat exchanger 121a～121c of its cold beam 12a～12c by control consists of.Such valve 14a～14c drives based on the control signal of coming self-corresponding DDC20a～20c, to change aperture.
Air quantity adjustment unit 15a～15c is arranged on the pipeline that connects investigation mission outside the city or town machine 13 and corresponding cold beam 12a～12c, and the known flow control valve of amount of adjusting air that is flow into pipeline 122a～122c of its cold beam 12a～12c by control consists of.
Valve 16a, thus 16b consists of by drive the known flow control valve of adjusting its aperture based on the control signal from DDC21.Here, valve 16a is configured on the pipe arrangement of the heater that connects boiler etc. and investigation mission outside the city or town machine 13, and control is fed into the amount of hot water HW of the heat(ing) coil 131 of investigation mission outside the city or town machine 13.Here, valve 16b is configured on the pipe arrangement of the heater that connects cooling tower etc. and investigation mission outside the city or town machine 13, and control is fed into the amount of cold water CW of the cooling coil 132 of investigation mission outside the city or town machine 13.
Send water temperature sensor 18 to be consisted of with the known temperature sensor of the temperature of the cold-producing medium in the pipe arrangement 14 by the measurement cold-producing medium of flowing through.This measurement result is sent to each DDC20a～20c.
Consisted of by the flow through known temperature sensor of temperature of the adjusting air in the pipeline 15 of measurement for gas sensor 19.This measurement result is sent to DDC21.
DDC20a～20c is with respect to the cold beam 12a～12c of correspondence and arrange, and by the computer of the storage device of arithmetic unit, memory and hard disk etc. with CPU etc. etc.; Consist of with the program of being installed in this computer.That is, by the cooperation of hardware unit and software, above-mentioned hardware resource is by programme-control, and as shown in Figure 2, I/F section 201, comparing section 202, dewfall state operational part 203 and storage part 204 are implemented.For easy, below, take the situation of DDC20a as example, its structure is described, DDC20b, 20c also have the structure equal with DDC20a, and therefore the description thereof will be omitted.
I/F section 201 and valve 14a, interior sensor 17a, send water temperature sensor 18, DDC21 to be electrically connected, between them, carry out the exchange of various information, and should various information be sent to drive division 212, comparing section 202 and dewfall state operational part 203 as required.Again, I/F section 201 also and be arranged on by the Remote in conditioned space 11a～11c, operation panel and be electrically connected inputs by the design temperature of conditioned space 11a～11c based on the operation input from user etc.
Comparing section 202 relatively by interior sensor 17a institute instrumentation by the dew-point temperature of conditioned space 11a with by the coolant-temperature gage that send that send 18 instrumentations of water temperature sensor, and calculate their difference.
Dewfall state operational part 203 works as the 1st operational part, the comparative result of section 202 based on the comparison, the dewfall state of the cold beam 12a of computing.The heat exchanger 121a that this dewfall state refers to be illustrated in cold beam 12a produces the index of the possibility of dewfall.In this example, to producing dewfall possibility higher " danger ", having " attentions ", lower " drying " these 3 the dewfall states of generation dewfall possibility of producing the dewfall possibility to carry out computing and set.These dewfall states carry out computing based on the threshold value that is stored in the storage part 204.The dewfall state that calculates is sent to DDC21 by I/F section 201.
DDC21 is set to the epigyny device of DDC20a～20c, and by the computer of the storage device of arithmetic unit, memory and hard disk etc. with CPU etc. etc.; Consist of with the program of being installed in this computer.That is, by the cooperation of hardware unit and software, above-mentioned hardware resource is by programme-control, and as shown in Figure 4, I/F section 211, drive division 212, total state operational part 213, storage part 214 and dewfall prevent that section 215 is implemented.
I/F section 211 and investigation mission outside the city or town machine 13, valve 16a, 16b, confession gas sensor 19 and DDC20a～20c are electrically connected, between them, carry out the exchange of various information, and as required should various information be sent to drive division 212, total state operational part 213 and dewfall and prevent section 215.
Total state operational part 213 works as the 2nd computing, and it comes computing to sum up the dewiness attitude based on the dewfall state that is set by DDC20a～20c dewfall state operational part 203 separately and the rule that is stored in the storage part 214, to set.This summary dewiness attitude is the index that arbitrary heat exchanger of cold beam 12a～12c of comprising in the air handling system 1 of expression produces the possibility of dewfall.In this example, be set with and produce dewfall possibility higher " danger ", have lower " drying " these 3 of " attention ", generation dewfall possibility that produces the dewfall possibility to sum up the dewiness attitude.The summary dewiness attitude that sets is sent to dewfall and prevents section 215.
The purpose of setting the rule shown in Fig. 5 is the more reliably generation of Antidewing.Specifically, the dewfall state of all cold beams is in the situation of " danger ", sums up the dewiness attitude and is set to " danger ".Again, the dewfall state of at least 1 cold beam in a plurality of cold beams is " danger ", and the dewfall state of other cold beam is in the situation of " attention " or " drying ", sums up the dewiness attitude and is set to " danger ".Again, the dewfall state of all cold beams is in the situation of " attention ", sums up the dewiness attitude and is set to " attention ".Again, the dewfall state of at least 1 cold beam in a plurality of cold beams is " attention ", and the dewfall state of other cold beam is in the situation of " drying ", sums up the dewiness attitude and is set to " attention ".Again, the dewfall state of all cold beams is in the situation of " drying ", sums up the dewiness attitude and is set to " drying ".
In addition, rule is not restricted to form shown in Figure 5, and it can be suitably by free setting, and for example in order to realize more energy-saving, the summary dewiness attitude that yet can be set as " danger " or " attention " is not calculated.Again, Fig. 5 shows the number of units that does not limit cold beam and the situation that cold beam 12a～12n is set, but by its number of units is made as 3, certainly goes for this example.
Dewfall prevents that section 215 from working as control part, and it is controlled feed air temperature based on the summary dewiness attitude that is set by total setting state section 213.
As described above, in the larger situation of sensible heat load (temperature load) or latent heat load (moisture), feed air temperature is descended, in the less situation of load, the method that feed air temperature is risen can be cut down energy consumption.Yet, feed air temperature is excessively risen, risen by the dew-point temperature of conditioned space 11a～11c, the worry that produces dewfall is arranged.
At this, in this example, dewfall prevents section 215 based on summing up dewiness attitude control feed air temperature, and Antidewing produces thus.Specifically, summing up the dewiness attitude is in the situation of " danger ", that is, be in the situation about sending more than the coolant-temperature gage by the indoor dew-point temperature in any one space of conditioned space 11a～11c, and feed air temperature is descended 2 ℃.Thus, it is lower than the dew-point temperature of investigation mission outside the city or town machine 13 that feed air temperature becomes, and then dehumidified by investigation mission outside the city or town machine 13.
Again, summing up the dewiness attitude is in the situation of " attention ", that is, being from more than the temperature of sending low 2 ℃ of coolant-temperature gage and in less than the situation in the scope of sending coolant-temperature gage by the indoor dew-point temperature in any one space among conditioned space 11a～11c, feed air temperature is descended 1 ℃.Thus, reduce owing to be fed into the humidity of air feed of heat exchanger 121a～121c of cold beam 12a～12c, its result, the heat exchanger 121a that can prevent at cold beam 12a～12c～121c produces dewfall.
Again, summing up the dewiness attitude be in the situation of " drying ", that is, by among conditioned space 11a～11c the indoor dew-point temperature in having living space than in the lower situation of the temperature of sending low 2 ℃ of coolant-temperature gage, make 0.5 ℃ of feed air temperature rising.Like this, feed air temperature is risen, therefore can realize energy-conservation.At this moment, owing to send the relatively indoor dew-point temperature of coolant-temperature gage enough low, also can produce by Antidewing even improve feed air temperature.
As described above, according to this example, because can pass through to control feed air temperature based on summing up the dewiness attitude, thereby make heat exchanger 121a～121c of cold beam 12a～12c not produce dewfall ground control feed air temperature, its result can realize energy-saving.
Again, change after the feed air temperature, before indoor dew-point temperature changes, need certain response time.That is, the variation of feed air temperature need to be waited for the time of estimating the response time effect.At this, dewfall prevents that section 215 from implementing the judgement that feed air temperature changes by the cycle with time of waiting for this effect, can more effectively realize preventing and energy-saving of dewfall.
Again, in this example, the dewfall state is illustrated as an example of the situation of carrying out as shown in Figure 3 digitlization and setting example, but the method for setting the dewfall state is not limited to this, suitably free setting.For example, as shown in Figure 6, the setting that also can simulate.In this Fig. 6, with numeric representation dewfall state, sending coolant-temperature gage is than in the situation below the temperature of sending low 2 ℃ of coolant-temperature gage, the dewfall state is made as 0, send coolant-temperature gage in situation about sending more than the coolant-temperature gage, the dewfall state be made as 100, from this than the temperature of sending low 2 ℃ of coolant-temperature gage to sending coolant-temperature gage) scope, be in along with sending coolant-temperature gage to rise the state that the dewfall state also rises.Value maximum in each dewfall state with cold beam 12a～12c of setting like this is as summing up the dewiness attitude.And feed air temperature is made as-0.02 * summary dewiness attitude.Thus, owing to can be set more imperceptibly feed air temperature by the state of conditioned space 11a～11c according to each, so can more effectively realize preventing and energy-saving of dewfall.
Again, the dewfall state not only can carry out simulated setting as shown in Figure 6, also can carry out as shown in Figure 7 the simulated setting of many grades.In this Fig. 7, sending coolant-temperature gage is than in the situation below the temperature of sending low 4 ℃ of coolant-temperature gage, and the dewfall state is made as-50, and sending coolant-temperature gage is to send in the above situation of coolant-temperature gage, and close dew temperature is made as 100.Again, make from this than the temperature of sending low 4 ℃ of coolant-temperature gage to changing than the gradient of the temperature of sending low 2 ℃ of coolant-temperature gage to the scope of sending coolant-temperature gage than the scope of the temperature of sending low 2 ℃ of coolant-temperature gage with from this.Thus, owing to can be set more imperceptibly feed air temperature by the state of conditioned space 11a～11c according to each, so can more effectively realize preventing and energy-saving of dewfall.
In this example, although be illustrated as an example of the situation of being set the dewfall state by DDC20a～20c example, also can set the dewfall state by DDC21 again.At this moment, by with interior sensor 17a～17c and send water temperature sensor 18 to be connected with DDC21, and comparing section 202 and dewfall state operational part 203 are set further in DDC21, can realize preventing and energy-saving of dewfall.
Again, in this example, also can the valve 14a of the flow of control cold-producing medium be driven based on by the interior sensor 17a～indoor temperature of 17c institute instrumentation and the design temperature that is imported into I/F section 201, the drive division of adjusting its aperture further is set in DDC20a～20c.Thus, control the flow of the cold-producing medium of the heat exchanger that is fed into cold beam 12a～12c, make heat transmit variation by utilizing the radiation, the convection current that are produced by this heat exchanger, can make by the indoor temperature change generated in case of conditioned space 11a～11c.For example, cold water supplies to from investigation mission outside the city or town machine 13 in the situation of cold beam 12a, when being lower than design temperature by the indoor temperature of conditioned space 11a, reduces the aperture of valve 14a, and reduces the amount of the cold water that supplies to cold beam 12a.Thus, the heat transmission of being undertaken by heat exchanger diminishes, and therefore can prevent the reduction of indoor temperature.On the other hand, when higher than design temperature by the indoor temperature of conditioned space 11a, increase the aperture of valve 14a, and increase the amount of the cold water that supplies to cold beam 12a.Thus, the heat transmission of being undertaken by heat exchanger becomes large, therefore can prevent the reduction of indoor temperature.(the 2nd example)
Then, the 2nd example of the present invention is described.
This example is also considered by the air-conditioning load of conditioned space, so that feed air temperature is controlled except considering above-mentioned dewfall state and summing up the dewiness attitude.
Further, in this example, based on each by the air-conditioning load of conditioned space, namely, assessment each by the room temperature of conditioned space with for each " room temperature state " of difference that should be set to by conditioned space the design temperature of target temperature, calculate the feed air temperature of regulating air.In the following description, in the DDC20a～20c and DDC21 of above-mentioned the 1st example, further set room temperature state or the total room temperature state narrated later.Therefore, in this example, to giving identical title and symbol with the equal member of the 1st example, suitably the description thereof will be omitted.
As shown in Figure 8, the air handling system 2 that relates to of this example has: be configured in by the cold beam 12a～12c at the ceiling back side of conditioned space 11a～11c; With will to open-air carried out heat treated adjusting air and heat treatment cold-producing medium (hot and cold water) supply to the investigation mission outside the city or town machine 13 of cold beam 12a～12c.With on the pipe arrangement 14, be provided with valve 14a～14c that the flow of the cold-producing medium that is fed into each heat exchanger 121a～121c is adjusted at the cold-producing medium between the heat exchanger 121a～121c that is arranged on investigation mission outside the city or town machine 13 and each cold beam 12a～12c.On the pipeline 15 that connects investigation mission outside the city or town machine 13 and cold beam 12a～12c, be provided be fed into air quantity adjustment unit 15a～15c that each is adjusted by the amount of the adjusting air of conditioned space 11a-11c by cold beam 12a～12c again.On investigation mission outside the city or town machine 13, be provided with the valve 16a that the amount that is directed to the cold-producing medium of investigation mission outside the city or town machine 13 from heat power supply device is adjusted, 16b again.
On the other hand, in by conditioned space 11a～11c, dispose instrumentation by the interior sensor 17a～17c of the room temperature in the conditioned space and dew-point temperature.Again, at cold-producing medium with on the pipe arrangement 14, be provided with instrumentation be fed into from investigation mission outside the city or town machine 13 cold beam 12a～12c cold-producing medium send coolant-temperature gage send water temperature sensor 18.Again, on pipeline 15, have the adjusting air that instrumentation supplies with from investigation mission outside the city or town machine 13 feed air temperature for gas sensor 19.
Control device as the such air handling system 2 of control has: based on the DDC20-1a～20-1c of the aperture of instrumentation output control valve 14a～14c of interior sensor 17a～17c; With based on from indoor 17a～17c, send water temperature sensor 18, for gas sensor 19 and the obtained various information of DDC20a～20c, the DDC21-1 of the running of control investigation mission outside the city or town machine 13 and the aperture of valve 16.
In Fig. 8, give identical label a～c to the identical associated components by conditioned space 11a～11c of correspondence again.
Here, DDC20-1a～20-1c is with respect to the cold beam 12a～12c of correspondence and arrange, and by the computer of the storage device of arithmetic unit, memory and hard disk etc. with CPU etc. etc.; Consist of with the program of being installed in this computer.That is, by the cooperation of hardware unit and software, above-mentioned hardware resource is by programme-control, and as shown in Figure 9, I/F section 201, comparing section 202-1, dewfall state operational part 203, storage part 204-1 and room temperature state operational part 205 are realized respectively.
Comparing section 202-1 relatively by interior sensor 17a～17c institute instrumentation, corresponding by the dew-point temperature of conditioned space 11a～11c with by the coolant-temperature gage that send that send 18 instrumentations of water temperature sensor, and calculate their difference.Again, comparing section 202-1 relatively by interior sensor 17a～17c institute instrumentation, corresponding by the indoor temperature of conditioned space 11a～11c or dew-point temperature, and should be by the design temperature of conditioned space 11a～11c, and calculate their difference.
The dewfall state operational part 203 based on the comparison 202-1 of section compares dew-point temperature and the comparative result that send coolant-temperature gage, sets the dewfall state of corresponding cold beam 12a～12c.The dewfall state of this dewfall state and above-mentioned the 1st example is equal to.
Storage part 204-1 is pre-stored to have the dewfall setting state section 203 that has illustrated in above-mentioned the 1st example to be used for the threshold value of the computing of dewfall state.Again, storage part 204-1 is also pre-stored has room temperature state operational part 205 for the threshold value of the computing of room temperature state.Concrete condition about this threshold value is narrated in the back.
Room temperature state operational part 205 works as the 3rd operational part, and it is the 202-1 of the section comparative result of indoor temperature and design temperature relatively based on the comparison, computing corresponding by the room temperature state of conditioned space 11a～11c.The room temperature state that this quilt calculates is sent to DDC21-1 by I/F section 201.
Here, room temperature state be expression corresponding by the index of the state of temperature of conditioned space 11a～11c.In this example, for example in the situation of cooling operation, be provided with following 3 room temperature states: indoor temperature is lower than design temperature, " surplus " that refrigerating capacity is higher than air-conditioning load; Indoor temperature is identical with design temperature, " suitably " of refrigerating capacity and air-conditioning load balance; Indoor temperature is higher than design temperature, " scarce capacity " that the refrigerating capacity of air-cooling system is lower than air-conditioning load.These room temperature states are set based on the threshold value that is stored among the storage part 204-1.This threshold value is set based on the difference of indoor temperature and design temperature.For example, when valve 14a was standard-sized sheet, cold beam 12a regarded room temperature state as " scarce capacity ".Again, when valve 14a was " closing " or " low aperture ", cold beam 12a regarded room temperature state as " surplus ".
DDC21-1 is set to the epigyny device of DDC20-1a～20-1c, and by the computer of the storage device of arithmetic unit, memory and hard disk etc. with CPU etc. etc.; Consist of with the program of being installed in this computer.That is, by the cooperation of hardware unit and software, above-mentioned hardware resource is by programme-control, and as shown in figure 10, I/F section 211, drive division 212, total state operational part 213-1, storage part 214-1 and dewfall prevent that the 215-1 of section is implemented.
Total state operational part 213-1 is based on the dewfall state that is set by DDC20-1a～20-1c dewfall state operational part 203-1 separately, and the rule that is stored among the storage part 214-1 is set summary dewiness attitude.The summary dewiness attitude of this summary dewiness attitude and above-mentioned the 1st example is equal to.
Again, total state operational part 213-1 is based on the room temperature state that is set by DDC20-1a～20-1c room temperature state operational part 205 separately, and the rule that is stored among the storage part 214-1 is set total room temperature state.
Here, total room temperature state be comprise in the expression air handling system 1 by the index of the state of the indoor temperature of conditioned space 11a～11c.In this example, in the situation of cold air, be provided with following 3 total room temperature states: the indoor temperature by conditioned space 11a～11c is lower than design temperature, " surplus " that refrigerating capacity is higher than air-conditioning load; Identical with design temperature by the indoor temperature of conditioned space 11a～11c, " suitably " of refrigerating capacity and air-conditioning load balance; Higher than design temperature by the indoor temperature of conditioned space 11a～11c, refrigerating capacity is carried low " scarce capacity " than idling.
The pre-stored rule that has total state operational part 213-1 to be used for the computing of summary dewiness attitude of storage part 214-1.The rule of this rule and above-mentioned the 1st example is equal to.Again, the pre-stored rule that has total state operational part 213-1 to be used for the computing of total room temperature state of storage part 214-1.In this example, this rule is made as total room temperature state with maximum room temperature states.For example, even the situation that room temperature state is " scarce capacity " total also room temperature state is made as " scarce capacity ", then reduces by 1 ℃ in when refrigeration with feed air temperature, feed air temperature is improved 1 ℃ heating formula.Again, room temperature state all is in the situation of " surplus ", total room temperature state to be made as surplus, then at refrigeration-type feed air temperature is improved 1 ℃, when heating feed air temperature is reduced by 1 ℃.
Dewfall prevents that the 215-1 of section from setting feed air temperature based on the summary dewiness attitude that is set by total state operational part 213-1 and total room temperature state.Its concrete condition below is described.
At first, dewfall prevents the 215-1 of section computing based on the feed air temperature of summing up the dewiness attitude, more particularly, and the difference of computing itself and current feed air temperature.In this example, as an example, in the situation of cold air operation processed, when summary dewiness attitude is " danger ", make feed air temperature from 2 ℃ of current drop in temperatures.When summary dewiness attitude is " attention ", make feed air temperature from 1 ℃ of current drop in temperature again.When summary dewiness attitude is " drying ", feed air temperature is risen 0.5 ℃ from current temperature again.
Again, dewfall prevents that the 215-1 of section computing is based on the difference of the feed air temperature of total room temperature state.In this example, as an example, in the situation of cold air operation processed, when total room temperature state is " surplus ", the difference of feed air temperature is made as the value (for example, 0.5 ℃) of regulation, make feed air temperature from current feed air temperature this value that only rises.Again, when total room temperature state is " scarce capacity ", the value of difference is made as the value (for example ,-1 ℃) of regulation, makes feed air temperature from current temperature this value that only descends.Again, when total room temperature state is " suitably ", difference is made as ± 0 ℃, does not change feed air temperature.
Respectively computing is based on the difference of the feed air temperature of summing up the dewiness attitude with based on the difference of the feed air temperature of total room temperature state, and dewfall prevents that the 215-1 of section from doing addition to the value of these two differences, confirms consequently in the no scope that is in regulation.For example, with the value after the value addition of two differences be ± 2 ℃ with in the situation in the interior scope that waits regulation, increase this value and be set as new feed air temperature in current temperature, on the other hand, this value for example surpasses in+2 ℃ the situation, increase+2 ℃ and be set as new feed air temperature in current temperature, surpass in-2 ℃ the situation, increase-2 ℃ and be set as new feed air temperature in current temperature.Like this, " the bound processing " of difference limit between set upper limit value and lower limit of carrying out feed air temperature is that air-conditioning system can't be replied the variation of feed air temperature control because the amplitude of variation of worry feed air temperature is excessive.As long as higher limit and lower limit are based on being stipulated by the capacity of the air-conditioning load in control space or investigation mission outside the city or town machine etc.
Set new feed air temperature according to the difference and the current feed air temperature that have carried out after such bound is processed.
In addition, in the above description, although to doing add operation based on the difference of summing up the feed air temperature that the dewiness attitude calculates with based on the feed air temperature difference that total room temperature state is calculated, be illustrated in the mode of assisting plus-minus to process, but also can compare both and adopt less value, replace two differences are done add operation.
At the transition point in moisture more season etc., have room temperature and be situation suitable but may dewfall.In this case, in this example, because feed air temperature descends according to summing up the dewiness attitude, generation that therefore can Antidewing.
Like this, according to this example, set together the more effectively generation of Antidewing by summing up the dewiness attitude with total room temperature state.
In addition, what illustrate in this example is, based on being set to the design temperature of target temperature by conditioned space by the room temperature of conditioned space with to this, obtain the situation of feed air temperature by room temperature state and total room temperature state, but in the present invention, also can be by other control method, for example feed air temperature is obtained in proportion control (P control), proportional plus integral control (PI control), PID control (PID control).
(the 3rd example)
Below, the 3rd example of the present invention is described.Again, this example is the embodiment that has utilized the dehumidification function of the investigation mission outside the city or town machine 13 in above-mentioned the 2nd example.Therefore, in this example, to giving identical title and symbol with the equal member of the 2nd example, suitably the description thereof will be omitted.

On the other hand, in by conditioned space 11a～11c, dispose instrumentation by the interior sensor 17a～17c of the indoor temperature in the conditioned space and dew-point temperature.Again, at cold-producing medium with on the pipe arrangement 14, be provided with instrumentation be fed into from investigation mission outside the city or town machine 13-1 cold beam 12a～12c cold-producing medium send coolant-temperature gage send water temperature sensor 18.Be provided with at pipeline 15 again: the feed air temperature of the adjusting air that instrumentation is supplied with from investigation mission outside the city or town machine 13-1 for gas sensor 19; With instrumentation from the dew-point temperature of the air feed of investigation mission outside the city or town machine 13-1 (below be called " air feed dew-point temperature ".) air feed dew point temperature sensor 30.
Control device as the such air handling system 3 of control has: based on the DDC20-1a～20-1c of the aperture of instrumentation output control valve 14a～14c of interior sensor 17a～17c; With based on from indoor 17a～17c, send water temperature sensor 18, for the obtained various information of gas sensor 19 and DDC20a～20c and air feed dew point temperature sensor 30, the DDC21-1 of the running of control investigation mission outside the city or town machine 13-1 and the aperture of valve 16.
Again, in Figure 11, to correspondence identical also given identical label a～c by the associated components of conditioned space 11a～11c.
Investigation mission outside the city or town machine 13-1 has: the heat(ing) coil 131 that the hot water HW that is supplied to by the heat power supply device from boiler etc. heats open-air; The cooling coil 132 that the cold water CW that is supplied to by the heat power supply device from cooling tower etc. cools off open-air; With will carry out the fan 133 that heat treated open-air (air feed) is sent by heat(ing) coil 131 or cooling coil 132.Here, investigation mission outside the city or town machine 13-1 has the function of utilizing these members to dehumidify.On investigation mission outside the city or town machine 13-1, also can further be provided for cooling off the again special-purpose device of the dehumidifying such as heating or drying again.
DDC21-2 is set to the epigyny device of DDC20-1a～20-1c, and by the computer of the storage device of arithmetic unit, memory and hard disk etc. with CPU etc. etc.; Consist of with the program of being installed in this computer.That is, by the cooperation of hardware unit and software, above-mentioned hardware resource is by programme-control, and as shown in figure 12, I/F section 211, drive division 212, total state operational part 213-1, storage part 214-1 and dewfall prevent that the 215-2 of section is implemented.
Dewfall prevents that the 215-2 of section from working as control part, and it carries out computing based on the summary dewiness attitude by the computing of the total setting state 213-1 of section institute to feed air temperature.Again, dewfall prevents that the 215-2 of section is based on coming computing air feed dew-point temperature by the summary dewiness attitude of the total setting state 213-1 of section institute computing, to set.
About feed air temperature, total room temperature state is in the situation of " scarce capacity ", then when refrigeration feed air temperature is reduced by 1 ℃, when heating feed air temperature is improved 1 ℃.Again, room temperature state all is in the situation of " surplus ", total room temperature state to be made as surplus, then when refrigeration feed air temperature is improved 1 ℃, when heating feed air temperature is reduced by 1 ℃.
On the other hand, about the air feed dew-point temperature, summing up the dewiness attitude is in the situation of " danger ", and the air feed dew-point temperature is descended 2 ℃.When summary dewiness attitude is " attention ", the air feed dew-point temperature is descended 1 ℃ again.When summary dewiness attitude is " drying ", the air feed dew-point temperature is risen 0.5 ℃ again.About such air feed dew-point temperature, measured by air feed dew point temperature sensor 30.
Set like this feed air temperature and air feed dew-point temperature, drive division 212 is controlled investigation mission outside the city or town machine 13 etc. based on this feed air temperature that is set and air feed dew-point temperature.Here, about the air feed dew-point temperature, control with the dehumidification function of investigation mission outside the city or town machine 13.
Like this, according to this example, owing to control the air feed dew-point temperature, the therefore more effectively generation of Antidewing based on summing up the dewiness attitude.
(the 4th example)
Below, the 4th example of the present invention is described.Again, this example further arranges the open-air dew point temperature sensor of the dew-point temperature of measuring open-air in above-mentioned example.Therefore, in this example, to giving identical title and symbol with the equal member of the 1st example, suitably the description thereof will be omitted.
As shown in figure 13, the air handling system 4 that relates to of this example has: be configured in by the cold beam 12a～12c at the ceiling back side of conditioned space 11a～11c; With will to open-air carried out heat treated adjusting air and heat treatment cold-producing medium (hot and cold water) supply to the investigation mission outside the city or town machine 13 of cold beam 12a～12c.With on the pipe arrangement 14, be provided with valve 14a～14c that the flow of the cold-producing medium that is fed into each heat exchanger 121a～121c is adjusted at the cold-producing medium between the heat exchanger 121a～121c that is arranged on investigation mission outside the city or town machine 13 and each cold beam 12a～12c.On the pipeline 15 that connects investigation mission outside the city or town machine 13 and cold beam 12a～12c, be provided be fed into air quantity adjustment unit 15a～15c that each is adjusted by the amount of the adjusting air of conditioned space 11a～11c by cold beam 12a～12c again.On investigation mission outside the city or town machine 13, be provided with the valve 16a that the amount that is directed to the cold-producing medium of investigation mission outside the city or town machine 13 from heat power supply device is adjusted, 16b again.
On the other hand, in by conditioned space 11a～11c, dispose instrumentation by the interior sensor 17a～17c of the indoor temperature in the conditioned space and dew-point temperature.Again, at cold-producing medium with on the pipe arrangement 14, be provided with instrumentation be fed into from investigation mission outside the city or town machine 13 cold beam 12a～12c cold-producing medium send coolant-temperature gage send water temperature sensor 18.Again, on pipeline 15, have the adjusting air that instrumentation supplies with from investigation mission outside the city or town machine 13 feed air temperature for gas sensor 19.The open-air dew point temperature sensor 40 that the dew-point temperature of measuring open-air further, is arranged in the outer setting of air handling system 4.
Control device as the such air handling system 4 of control has: based on the DDC20a～20c of the aperture of instrumentation output control valve 14a～14c of interior sensor 17a～17c; With based on from indoor 17a～17c, send water temperature sensor 18, for gas sensor 19, open-air dew point temperature sensor 40 and the obtained various information of DDC20a～20c, the DDC21-3 of the running of control investigation mission outside the city or town machine 13 and the aperture of valve 16.
Again, in Figure 13, to correspondence identical also given identical label a～c by the associated components of conditioned space 11a～11c.
DDC21-3 is set to the epigyny device of DDC20a～20c, and by the computer of the storage device of arithmetic unit, memory and hard disk etc. with CPU etc. etc.; Consist of with the program of being installed in this computer.That is, by the cooperation of hardware unit and software, above-mentioned hardware resource is by programme-control, and as shown in figure 14, I/F section 211, drive division 212, total state operational part 213, storage part 214 and dewfall prevent that the 215-3 of section is implemented.
Dewfall prevents that the 215-3 of section from working as control part, and it carries out computing based on by the summary dewiness attitude of summing up dewiness 213 computings in attitude configuration part to feed air temperature.Again, summing up the dewiness attitude is " danger " or " attention ", and than in any one the high situation by the indoor dew-point temperature of the 11a～11c of interior sensor 17a～17c institute instrumentation, dewfall prevents that the 215-3 of section from making the rise of rotational speed of the fan 133 of investigation mission outside the city or town machine 13 with the dew-point temperature of the open-air of 40 instrumentations of open-air dew point temperature sensor.
Set like this rotating speed of feed air temperature and fan 133, drive division 212 is controlled investigation mission outside the city or town machine 13 etc. based on this feed air temperature that is set and rotating speed.
Higher according to the possibility of summing up the cold beam 12a of dewiness attitude～12c dewfall, and outdoor dew-point temperature is higher, and in the situation that namely humidity is higher, open-air is fed directly to by conditioned space 11a～11c, probably can produce dewfall.As open-air to by the inflow path of conditioned space 11a～11c, suppose it is the switching etc. of slot wind or door, window.At this, in order to prevent the inflow of such open-air, make the rise of rotational speed of fan 133, the air quantity of air feed is increased.Thus, higher than atmospheric pressure by making by the air pressure in conditioned space 11a～11c, so that flowed out to the outside by the air of conditioned space 11a～11c inside, can prevent that open-air from flowing into by among conditioned space 11a～11c.
As described above, according to this example, by based on summing up the dewiness attitude air quantity of air feed being increased, it is inner to prevent that open-air from flowing into by conditioned space 11a～11c, so its result, generation that can Antidewing.
In addition, this example also can be applicable to the 2nd, the 3rd above-mentioned example certainly.
Again, in the 1st～the 4th above-mentioned example, although to compare by the dew-point temperature of conditioned space 11a～11c with by the coolant-temperature gage that send that send 18 instrumentations of water temperature sensor, coming the situation of computing dewfall state according to their difference is that example is illustrated, but also can replace sending coolant-temperature gage with the temperature on the surface of heat exchanger 121a～121c.This surperficial temperature can be measured by the temperature sensor on the surface that is installed in heat exchanger 121a～121c.Even like this, also can realize and the above-mentioned equal action effect of the 1st～the 4th example.
