Described each the 1st aileron 12,12 ... be disposed at described blowing out in the path 14, described motor 30 is disposed at the described end that blows out the short brink of path 14, just can not make the described area of passage stenosis that blows out path 14 little because of disposing this motor 30.
As shown in Figure 2, described the 2nd aileron 13 is made of the band plate member with crooked section shape, is configured in the described downstream of path 14 and the position of approaching described blow-off outlet 4 of blowing out.The 2nd aileron 13 is by being to fascinate and change the blow-off direction of adjusting the longitudinal direction (being the short side direction of blow-off outlet 4) blow out air-flow in the center with its upper end.
This 2nd aileron 13 corresponds respectively to described blow- off outlet 4,4 ... configuration, its each the 2nd aileron 13,13 ... type of drive can consider interlock mode and independent mode.The interlock mode as shown in Figure 7, with described each blow- off outlet 4,4 ... corresponding described each the 2nd aileron 13,13 that is provided with ..., by the member 32,32 of mutual interlock ... connect, by single motor 31 to these each the 2nd aileron 13,13 ... drive.Independent mode as shown in Figure 8, with described each blow-off outlet 4 corresponding described each the 2nd aileron 13 that are provided with, respectively by the motor 31,31 of special use ... drive individually.In the driving of this dual mode, because the former interlock mode is to be driven by single motor 31, the structure of drive division is very simple, and the low advantage of cost is arranged.In contrast to this, indivedual type of drive of the latter have and can distinguish individually and fine to each described each blow- off outlet 4,4 ... the advantage adjusted of the blow-off direction that blows out the air-flow longitudinal direction.
About described infrared ray sensor 15, severally below for example all be fit to uses, with the zone of detected object unit piece formula sensor as a whole detection; In a direction detected object space segmentation is opened, respectively the one-dimensional array formula member sensor device that partition space is detected; Quadrature two directions are carried out in the detected object space separate, respectively two-dimensional array formula member sensor device that each partition space is detected etc.
To be sent to described control part 18 by the detection information of described infrared ray sensor 15 detected target object temperature, as the control basis of the described air-flow change device 52 of these control part 18 controls.
As mentioned above, described control part 18 according to the information that described infrared ray sensor 15 detects, is being controlled the interrelated action of described air quantity distributor gear 10 and the 1st aileron 12 and the 2nd aileron 13.And control part 18 makes the air-conditioning optimization by ability or the temperature of controlling air-conditioning simultaneously, improves the comfortableness of air-conditioning or the performance of saving the energy thus.For example, for each blow- off outlet 4,4 from described indoor set Z1 ... the stream condition that blows out, each blow- off outlet 4,4 ... between setting often all the same, but adjust according to indoor temperature distribution (heat load distribution) or people's distribution.For example in when refrigeration, air quantity be controlled on the one hand the high zone of temperature or the many zones of people increased blow out air quantity, on the other hand, to the low zone of temperature or unmanned area decreases blow out air quantity.And, for have the people Region control blow out the direction of air-flow, avoid air-flow directly to blow to the people, thus in order to reduce " air-flow sense " and control wind direction etc.
Here, action and the action effect for described indoor set Z1 describes.The indoor set Z1 of this example with described realization air-conditioning optimization, to improve its comfortableness or save the energy be purpose.In order to reach described purpose, guarantee that fully the control accuracy of 18 pairs of described air-flow change device 52 grades of described control part is crucial.Thereby, as the described infrared ray sensor 15 on the control basis of described control part 18, improve accuracy of detection, guarantee that the reliability of the information that detects is very important.Concrete enforcement to each structural element of indoor set just is embodied on the indoor set Z1 of this example based on the technological thought of this viewpoint.Therefore, in the indoor set Z1 of this example, bring into play desired function respectively based on distinctive structure separately, to realize comfortableness that the air-conditioning optimization is brought or the final purpose of saving the energy by described each inscape.Below, this is specifically described.
In the indoor set Z1 of this example, carry out Air Conditioning after the heat exchange by described heat exchanger 5, from described each blow- off outlet 4,4 ... blow to indoor.This time, blow out air-flow flow through described blow out path 14 parts in, to described each blow- off outlet 4,4 ..., carry out the air quantity adjustment by described air quantity distributor gear 10.That is, play each blow- off outlet 4,4 ... the mutual separately distributional effects that blows out air quantity.In addition, carry out the blow-off direction corrective action and the 13 longitudinal direction blow-off direction corrective actions of described the 2nd aileron of described the 1st aileron 12 transverse directions simultaneously.And, carry out other controls such as ability control, temperature control of air-conditioning simultaneously.These resultant effects have been realized the optimization of air-conditioning.
As previously mentioned, the optimization of so-called air-conditioning sends high-precision test information to described control part 18 by described infrared ray sensor 15 and realizes.And in the indoor set Z1 of this example, described infrared ray sensor 15 is owing to adopted following structure just to obtain high-precision test information.
The 1st, this example is disposed at described blow- off outlet 4,4 in the described indoor panel 2 with described infrared ray sensor 15 ... opening between the position promptly be exposed to indoor position.This structure can fully be guaranteed the visual field, detection space of described infrared ray sensor 15, makes infrared ray sensor 15 carry out high-precision test to the target object temperature.
The 2nd, because described infrared ray sensor 15 is configured in described each blow- off outlet 4,4 of described indoor panel 2 ... opening between the position, so from the suction air-flow of described suction inlet 3 or blowing out air-flow and can directly not blow to described infrared ray sensor 15 from described blow-off outlet 4.Following problem just can not take place: for example in the occasion that described infrared ray sensor 15 is disposed at suction inlet 3 sides, adhere to and influence the detection performance because of this infrared ray sensor 15 is subjected to sucking dust in the air-flow etc. in its result.Perhaps, this infrared ray sensor 15 is configured in the occasion at blow-off outlet 4 positions, this infrared ray sensor 15 brushes, generates dewfall on its surface and influence the detection performance owing to directly being subjected to cold air.Thus, can keep high-caliber detection performance for a long time.
The 3rd, with described infrared ray sensor 15 be installed on can the sweep mechanism 20 of motion scan on.By the control of described sweep mechanism 20, can allow 15 pairs of indoor Temperature Distribution of described infrared ray sensor and people's distribution carry out high-precision test.And, use an infrared ray sensor 15 can realize detection to object temperature, it detects, and information processing is easy to, its reliability is also higher.
These function synthesizeds are got up, because described infrared ray sensor 15 sends the information of detected high accuracy and high reliability to described control part 18, described indoor set Z1 can realize better air conditioning comfortableness and the performance of saving the energy.
On the other hand, because the special tectonic of air-flow change device 52 sides has also improved the comfortableness of air-conditioning and the performance of saving the energy.
Promptly, the 1st, this example, because described air quantity distributor gear 10 and the 1st aileron 12 and the 2nd aileron 13 are at described each blow- off outlet 4,4 ... can distinguish individual part independently each other, described each blow- off outlet 4,4 ... can more fine control the single characteristic that blows out air-flow according to indoor Temperature Distribution and people's distribution.
Relative therewith, at described each blow- off outlet 4,4 ... constitute each other can make described air quantity distributor gear 10 and described the 1st aileron 12 can be respectively independently, individually move, in addition, also can constitute at described each blow- off outlet 4,4 ... described the 2nd aileron 13 of chien shih moves in linkage mutually.In this occasion, at described each blow- off outlet 4,4 ... utilize described air quantity distributor gear 10 and the 1st aileron 12 to carry out trickle control respectively to the characteristic that blows out air-flow.
The 2nd, this example, described air quantity distributor gear 10 dispose a pair of distribution driving lever 11,11, this each distribute driving lever 11,11 when the described aperture area that blows out path 14 enlarges action, make respectively to be positioned at the long side that this blows out path 14; When this aperture area dwindles action, make to be positioned at the described upstream side that blows out path 14.When the described aperture area that blows out path 14 enlarges action, when promptly blowing out the increase of air quantity,, and flowing resistance is weakened because described distribution driving lever 11,11 is positioned at the described little position of flow velocity that blows out path 14, when guaranteeing to blow out air quantity, also weakened the air-supply noise.
These effects integrate, and the properties of flow that puffs away improves, and have improved the air conditioning comfortableness of described indoor set Z1 and have saved energy performance.
And attached effect below also having.
The 1st, in this example, with the continuous upstream section that blows out path 14 of described blow-off outlet 4, when disposing described air quantity distributor gear 10 and described the 1st aileron 12 respectively, dispose the driving mechanism 29 of described air quantity distributor gear 10 and the driving mechanism 30 of described the 1st aileron 12 respectively at the described both ends that blow out the long side direction of path 14.This structure makes described air quantity distributor gear 10 and the 1st aileron 12 and their driving mechanism 29,30 to be configured in blown out in path 14 parts by the described of space constraints with intensifying, thereby realizes slimming, the miniaturization of described indoor panel 2.
The 2nd, this example, when reducing (, blow out air quantity) is positioned at the described position that blows out the upstream side of path 14 when making described a pair of distribution driving lever 11,11 be formed in the described aperture area that blows out path 14 to dwindle.This structure can be suppressed at the described position that blows out the described blow-off outlet 4 of path 14 downstream sides effectively and form the sinuous flow air-flow, when preventing that this blow-off outlet 4 from nearby dewfall taking place, can prevent the pollution of the ceiling surface that the impact that blows out air-flow because of sinuous flow causes.

Fig. 9 and Figure 10 shows that the separate type air conditioner Z2 of the 2nd example of the present patent application.The indoor set Z1 of this indoor set Z2 and described the 1st example has identical essential structure.Different places is the structure of described infrared ray sensor 15.Therefore, below describe this example described infrared ray sensor 15 distinctive structures and the action effect that accompanies therewith etc. down in detail, structure in addition and action effect omission explanation.And, corresponding with the member of Figure 1 and Figure 2 in Fig. 9 and Figure 10, use the symbol identical with it.
In the indoor set Z2 of this example, configuration is described infrared during to sensor 15 in described indoor panel 2, at described each blow- off outlet 4,4 ... close described suction inlet 3 the edge and every certain interval 3 these infrared ray sensors 15 are installed respectively at the long side direction of this blow-off outlet 4.And with these each infrared ray sensors 15,15 ... directly be fixed on described edge.Then, will correspond respectively to described each blow- off outlet 4,4 ... each infrared ray sensor 15,15 ... the detected object scope be each defined in the certain limit of the blow-off direction of each corresponding blow-off outlet 4.And, also respectively its detected object scope is limited to certain limit along 3 infrared ray sensors 15 of the long side direction of blow-off outlet 4 configuration.Therefore, under this example, each infrared ray sensor 15 is to be the non-sweep type infrared ray sensor of detected object separately with the certain limit.
That is under this example, as shown in Figure 9,, be that the detected object scope is center and described each blow- off outlet 4,4 with described indoor set Z2, with the interior space from overlooking ... correspondingly be divided into four big regional A1-A4.Further, as detected object, corresponding respectively 3 infrared ray sensors 15 are divided into three little region S A, SB, SC with each of this four big regional A1-A4.The detected object of each infrared ray sensor 15 corresponds respectively to these little spatial dimension SA, SB, one of SC.According to such setting, when the detection information of described each infrared ray sensor 15 sends described control part 18 to, just distinguish out the information that this detection information is the little zone in which big zone easily.
Under this example, because the surface that described each infrared ray sensor 15 is disposed at described indoor panel 2 promptly is exposed to indoor position, so the detection visual field that can fully guarantee each infrared ray sensor 15 is carried out high accuracy to the temperature of target object and is detected.Thereby make described control part 18 utilize the control accuracy of this kind detection information raising, and then improve the comfortableness of air-conditioning and save energy performance described air-flow change device 52.And, when described this each infrared ray sensor 15 is carried out maintenance activity, be different from this each infrared ray sensor 15 for example be disposed at the inboard that sucks barrier (, do not expose at indoor position) situation, owing to needn't install and remove to sucking barrier, therefore, the inspection of this each infrared ray sensor 15 or mounting or dismounting operation are very convenient, very easy access.
And, owing to dispose 3 infrared ray sensors 15 respectively at described each blow-off outlet 4, and these each infrared ray sensor 15 respectively corresponding its detected object scopes, thereby can access following effect.
Promptly, corresponding relation between the detection information of each infrared ray sensor 15 and the indoor detected object scope is very clear and definite, and the action control that the air-flow change device 52 of described air quantity distributor gear 10 grades utilizes the detection information of this each infrared shape sensor 15 to carry out is carried out easily.
And, under this example, owing to correspond respectively to described each blow- off outlet 4,4 ... the fixing described infrared ray sensor 15 of several detected object scopes is set, and this each infrared ray sensor 15 just can while and FR Temperature Distribution and people's distribution in sensing chamber always like this.Its result utilizes the action control of described air quantity distributor gear 10 grades of this kind detection information more accurate, thereby can further improve the comfortableness of air-conditioning and save the energy.

Figure 11 and Figure 12 shows that the indoor set Z3 of the separate type air conditioner of relevant the present invention's the 3rd example.This indoor set Z3 appends design Temperature Humidity Sensor 16 described later in addition with the basis that is configured to of the indoor set Z2 of described the 2nd example.Therefore, below be the structure of described Temperature Humidity Sensor 16 and effect thereof and this Temperature Humidity Sensor 16 and the relation of described infrared ray sensor 15 etc. is described in detail for the peculiar structure of this example, and omit explanation for structure and action effect in addition.And, in Figure 11 and Figure 12, corresponding to the Fig. 1 in the 1st example and Fig. 2, and Fig. 9 in the 2nd example and member shown in Figure 10, use the symbol identical with it.
In the indoor set Z3 of this example, corresponding to described each blow- off outlet 4,4 ... this each blow- off outlet 4,4 at described indoor panel 2 ... the marginal portion of close suction inlet 3, every certain interval described infrared ray sensor 15 is installed at the long side direction of this blow-off outlet 4 respectively.In addition, at the long side direction of this blow-off outlet 4 of position of described each blow-off outlet 4 of the outer peripheral portion that corresponds respectively to described suction inlet 3 (specifically every certain interval, resemble interval) corresponding to described each infrared ray sensor 15, Temperature Humidity Sensor 16 (in other example, other temperature sensors also can be set replace this Temperature Humidity Sensor 16) is installed.Therefore, described each infrared ray sensor 15 and corresponding described Temperature Humidity Sensor 16 have same detected object scope (being each the little region S A-SC among each big regional A1-A4) respectively.
Described Temperature Humidity Sensor 16 detects respectively the humiture of the air-flow that sucks from the described suction inlet 3 corresponding to the spatial dimension of each Temperature Humidity Sensor 16, and sends this to described control part 18 as detection information.This detection information of sending from Temperature Humidity Sensor 16 is compared with the detection information (being the information of room objects object temperature) of described infrared ray sensor 15 described control part 18, as the revisal benchmark of the detection information of this infrared ray sensor 15.
That is to say, described infrared ray sensor 15 was that the radiation temperature with target object such as indoor metope, floor or people detects as the object temperature originally, in described control part 18, the detection information of this infrared ray sensor 15 is used as the control benchmark of the air quantity distributor gear 10 of described air-flow change device 52.But indoor, existing for example glass pane, the part that other partial radiations of heat generation device geometric ratio are high also have the part of low radiation such as metal covering.Thereby, if only use 15 pairs of target object of described infrared ray sensor to detect, when having high radiant section and low radiant section in the detected object scope, may detect and the very big abnormal temperature value of difference such as actual indoor heat load distribution.Therefore, send described control part 18 to as the control benchmark, might make comfortableness be subjected to very big influence, for example indoor privileged site is blowed the air quantity that surpasses necessity, form " cold excessively " or " overheated " at this position if this is detected the information former state.
On the other hand, known to experience, the inlet temperature of room air is close with this radiation temperature that sucks the former place of air usually.For example, inlet temperature is in 25 ℃, and described radiation temperature is about 23-27 ℃.Therefore, can imagine the radiation temperature of target object in advance according to the inhaled air temperature.
Like this, if by described infrared ray sensor 15 object temperature (radiation temperature) that detects and the radiation temperature of imagining in advance from intake air temperature very big unusual difference value is arranged, can carry out revisal for the detected temperatures of described infrared ray sensor 15 according to this default radiation temperature value.
The revisal of detected temperatures can be used a lot of methods.For example a kind of straightforward procedure, the zone in mean radiant temperature (detected temperatures after the revisal) Ts can (this kind be imagined radiation temperature TP in advance and is generally equal to inlet temperature by imagining radiation temperature Tp in advance, here just set and imagine radiation temperature Tp=inlet temperature in advance) add that the temperature-compensating Tofs of setting obtains, promptly
Ts＝Tp+Tofs
With this detected temperatures is carried out revisal.
In addition, also have other correction method, utilize threshold temperature Tth radiation temperature to be carried out the method for revisal as described later.This correction method between the detected temperatures of infrared ray sensor 15 and the inlet temperature well-behaved greatly from the time effective especially.For example shown in Figure 13, in S1 step, S2 step, S3 step, finish by infrared ray sensor 15 and carry out the calculating of average radiation temperature in the detection, zone of radiation temperature, the mensuration etc. of inlet temperature in regional, then, whether the temperature difference absolute value of judging mean radiant temperature and inlet temperature in the S4 step is bigger than the value Δ T1 that sets, if big, then carry out following revisal.
But, window etc. be and the outside between carry out the big surface of hot of ac.When the detection range of infrared ray sensor 15 comprises such surface element or the detected temperatures of infrared ray sensor 15 compare with inlet temperature more to high temperature side well-behaved from the time etc., can think that the air themperature of near surface is the temperature that is between inlet temperature and the detected temperatures.Thereby, in step S5 with after fixed threshold value sets in the early stage, when if the absolute value of the difference of inlet temperature and detected temperatures is bigger than threshold value Tth, on the difference of threshold value and detected temperatures, be multiplied by again consider that temperature on average distributes and the coefficient η of radiation temperature sense (η=0.3-0.7 degree, be by rule of thumb or the coefficient of being tried to achieve by experiment) compensating value (reference S6 step) of the temperature gap conduct that obtains.That is:
Tofs＝η(Tth-Ts)
Then, obtain according to the method again after the revisal radiation temperature TS ' afterwards, calculate mean radiant temperature (with reference to the S7 step) again.Then, whether the absolute value of judging mean radiant temperature and the difference of inlet temperature than the value ε that sets little (with reference to the S8 step), if little then revisal finishes, if not little, then in the S9 step, threshold value is upgraded, carried out the work of step S6-S8 again.
Threshold value in the S5 step is as long as suitably provide initial value.In step S6-S9, use dichotomy etc. upgrades processing repeatedly to threshold value, and the difference between mean radiant temperature and inlet temperature is enough little.
The radiation temperature on low-E surfaces such as metal changed very little within one day, this radiation temperature well-behaved from be a kind of definite value to low temperature side well-behaved from.This radiation temperature, what can consider in fact to show is mean temperature.Therefore, in this case, replace temperature in the radiation temperature scope below the threshold value Tth,, threshold value is carried out repeatedly approximation process from the initial setting value, can obtain correct revisal radiation temperature with described the same with the inlet temperature value.
In the method for using optical detecting, sensor meetings such as contamination owing to sensor in long-term the use produce deviation (deviation of detected value).But stablize the viewpoint of control for a long time from needs, wish to rely on revisal to correct contamination and wait the long-term deviation that causes.Therefore, little in the difference of concluding each radiation temperature, be subjected under the little situation of the influence of unusual especially radiation areas, can be with the small difference of inlet temperature and mean radiant temperature as deviation, carry out revisal according to the detected value of infrared ray sensor.For example, at the absolute value of mean radiant temperature and the difference of inlet temperature than the value Δ T2 that sets little (with reference to step S10), the absolute value of mean radiant temperature and the difference of each radiation temperature also can be set up following equation: Tofs=inlet temperature-mean radiant temperature (step S12) than under the little situation of set definite value Δ T3 (with reference to step S11).
Like this, because the existence of unusual especially radiant section, must be on the basis that the error of detected temperatures is revised, with this control benchmark as the air-flow change device 52 in the described control part 18.
And, to the imagination in advance of the radiation temperature of target object and the revisal of detected temperatures, carry out by control part 18.Therefore, " compensating device " among the present invention utilizes control part 18 to constitute.
As mentioned above, in the indoor set Z3 of this example, the detection information of described infrared ray sensor 15 is carried out revisal if during unusual especially situation according to the radiation temperature of imagination in advance of described Temperature Humidity Sensor 16 detected inlet temperatures to this, to revise the error with actual value.Thus, described air-flow change device 52 just can carry out suitable action control corresponding to indoor actual heating load distribution etc., thereby improves the comfortableness of air-conditioning of described indoor set Z3 or the performance of saving the energy.
The indoor set Z3 of this example is designed to not have the fixed form of scan function with described infrared ray sensor 15, and corresponding and described each blow-off outlet 4 carries out a plurality of installations to it.But in other examples, for example this infrared ray sensor 15 is carried out single configuration or several configurations, and can utilize sweep mechanism 20 to constitute to make it to have scan function.
Particularly, the device that this infrared ray sensor 15 configuration structures are arranged, be equiped with described Temperature Humidity Sensor 16,16 ... situation under, because this Temperature Humidity Sensor 16,16 ... detection information, prevented that sweep mechanism 20 from carrying out invalid action, the durability of described sweep mechanism 20 is improved, thereby has also improved the saving energy performance of described indoor set Z3.Promptly, as mentioned above, because described each Temperature Humidity Sensor 16,16 ... respectively with specific scope as the detected object scope, for example when described Temperature Humidity Sensor 16,16 ... whole or it is most of (for example, the Temperature Humidity Sensor that institute's fixed-ratio is above) all detects the radiation temperature of target object high the time, promptly, in indoor gamut or most scope, detect thermic load setting the load more than in, then be judged as and need not use described infrared ray sensor 15 to scan the temperature of target object in the sensing chamber.Just stop the action of described sweep mechanism 20 in this case.Like this, stop, for example in the running of air conditioner, reduced running time of this sweep mechanism 20, can correspondingly suppress the wearing and tearing of drive part compared with the situation that continues to make described sweep mechanism 20 actions by the action that makes sweep mechanism 20.Improve the durability of sweep mechanism 20 thus, and can reduce the running expense of air conditioner.
And, can judge by control part 18 whether the thermic load in indoor gamut or the most of scope is setting more than the load.The control that stops of sweep mechanism 20 is also carried out by control part 18.Therefore, " judgment means " among the present invention and " arresting stop " are made of described control part 18.
Under this example, described Temperature Humidity Sensor 16 is installed in the peripheral part of described suction inlet 3 and on the described suction grid 8 of the upstream side of described filter 9.In other example, for example in Figure 12 with symbol 16 ' indicated like that, also can be installed in the part of described horn mouth pipeline 7.

Figure 14 and Figure 15 shows that the indoor set Z4 of the separate type air conditioner of the present invention's the 4th example.This indoor set Z4 is with the basis that is configured to of the indoor set Z1 of described the 1st kind of example, and uses the device of the Temperature Humidity Sensor 16 in described the 3rd example of configuration.Therefore, below only promptly the relation of the structure of described warm and humid sensor 16 and this Temperature Humidity Sensor 16 and described infrared ray sensor 15 etc. is described in detail for the distinctive formation of this example, structure in addition and action effect then omit explanation.And in Figure 14 and Figure 15, corresponding to the Fig. 1 in the 1st example and Fig. 2, and Figure 11 in the 3rd example and member shown in Figure 12, the symbol identical used with it.
In the indoor set Z4 of this example, at two blow-off outlets 4,4 of corner part adjacent, that be positioned at described indoor panel 2 ... opening between the position, described infrared ray sensor 15 is installed on the described sweep mechanism 20.Simultaneously, a side of the described suction inlet 3 in indoor panel 2 is corresponding to described each blow- off outlet 4,4 ... separate certain interval at the long side direction of this blow-off outlet 4 three described Temperature Humidity Sensors 16 are installed respectively.
Indoor set Z4 under this example is the detected object of described infrared ray sensor 15 and Temperature Humidity Sensor 16 is separated fully independently with the difference of described the 1st example and the 3rd example.That is, in described the 1st example, described infrared ray sensor 15 carries out indoor people's the position and the detection of indoor temperature distribution simultaneously.In described the 3rd example, utilize the value of detecting of 16 pairs of described infrared ray sensors 15 of described Temperature Humidity Sensor to carry out revisal.Contrast therewith, in this example, described infrared ray sensor 15 just is used for the position of people in the sensing chamber, and described Temperature Humidity Sensor 16 just is used for the Temperature Distribution in the sensing chamber.In this example, the relevance of the control of this infrared ray sensor 15 and Temperature Humidity Sensor 16 separates.
According to this structure, 15 positions to the people of described infrared ray sensor are detected and are got final product, for example compare with the situation that indoor temperature distribution detects with the position to the people simultaneously, the detection information processing of this infrared ray sensor 15 is easier, thereby simplified control system correspondingly.Simultaneously,, compare, use low-cost described Temperature Humidity Sensor 16 can guarantee desired precision with described infrared ray sensor 15 for the detection of indoor Temperature Distribution.As its Overlay, can guarantee the precision of the information that detects and low cost.
