Figure 15 A and Figure 15 B are the effects to the mini blade 20 of the wind direction louver assembly 3 of the air conditioner of embodiment 1 The figure that fruit is illustrated.Figure 15 B is the mini blade 20 for indicating to be formed in the upper surface of middle layer vane plate 32 of blow-off outlet 2b Neighbouring sectional view.Figure 15 A is the air from blow-off outlet 2b indicated when mini blade being arranged without vane plate 320 in middle level Flowing figure.Figure 15 B is the flowing for indicating the air of blow-off outlet 2b when vane plate 32 in middle level is provided with mini blade 20 Figure.

As shown in fig. 15 a and fig. 15b, air from ventilation path 7 is separated from blow-off outlet 2b to being formed in upper layer vane plate Upside between 31 and middle layer vane plate 32/320 blows out region FA and is formed in middle layer vane plate 32/320 and lower leave plate Downside blowout region BA blowout between 33.But as shown in fig. 15, mini blade is set in no vane plate 320 in middle level In the case where, such as warming operation when making further downward from the air of ventilation path 7 using each vane plate like that, come The air on self-ventilation road 7 is not removed after encountering the upstream side end of middle layer vane plate 320 along blade plate surface, in middle level leaf The upper surface side of sheet 320 generates turbulent flow due to vortex etc..In this way, because between upper layer vane plate 31 and middle layer vane plate 320 The turbulent flow of vortex etc. that generates of upside blowout region FA, under between middle layer vane plate 320 and lower leave plate 33 The air of side blowout region BA has an impact, and blows out region BA's with from downside sometimes from the air of upside blowout region FA Air mixing.As a result, generating blow out the middle temperature from upside blowout region FA air with cannot distinguish between and coming from down Side blows out the case where air of the high-temperature of region BA.In order to solve the problems, in the air conditioner of embodiment 1 In, vane plate 32 is provided with mini blade 20 in middle level.

As shown in fig. 15b, when vane plate 32 is provided with mini blade 20 in middle level, such as warming operation when utilize like that When each vane plate makes further downward from the air of ventilation path 7, the air from ventilation path 7 is directed to wind direction hundred up and down Leaf 30 and from upside blowout region FA (the first blow-off outlet) and downside blow out region BA (the second blow-off outlet) blow out downwards.This When, the air from ventilation path 7 specifically utilizes 20 edge of mini blade for the upstream side end for being set to middle layer vane plate 32 Blade plate surface without removing, inhibit the generation of the upper surface of middle layer vane plate 32 vortex of side etc., blow out glibly Air in middle level flow by the upper surface of vane plate 32 side.It should be as a result, becoming reliably can separately blow out from upside blowout area The air of the air of the middle temperature of domain FA (the first blow-off outlet) and the high-temperature from downside blowout region BA (the second blow-off outlet) Structure.In addition, illustrating to make from ventilation path 7 as when warming operation using middle layer vane plate 32 in above description The rectification effect effect that mini blade 20 when air is downward generates, but be able to recognize that the rotation of middle layer vane plate 32 and be located at it When its position, mini blade 20 also shows the rectification effect of upside blowout region FA (the first blow-off outlet).

[warm-cold sensitivity detection control]

In the air conditioner of embodiment 1, based on from force-feeling sensor 10, warm-cold sensitivity sensor 11, surface temperature The various information of the temperature sensor of temperature of sensor, insolation sensor and the detection each position of heat exchanger 5 etc., the air tune Section machine is by drive control.

For example, force-feeling sensor 10 and warm-cold sensitivity sensor 11 are based on from the red of indoor air conditioning subject area Presence, the movement of people and the structure of thermal image information etc. of outside line detection people.According to the work of the air conditioner by embodiment 1 The thermal image information obtained for the thermopile sensor of warm-cold sensitivity sensor 11 detects warm-cold sensitivity.

The air conditioner of embodiment 1 is based on the thermal image infomation detection air tune from warm-cold sensitivity sensor 11 The structure for saving " warm-cold sensitivity " of the people in subject area, the index of " warm-cold sensitivity " of " heat ", " cold " felt as expression people, one As be often used PMV index (Predicted Mean Vote: prediction warm-cold sensitivity evaluation).In PMV index, for "+3 (Hot: heat) " 7 grades of evaluation scales of~" -3 (Cold: cold) ".It, can the small committee member of warm-cold sensitivity by air conditioning health engineering in embodiment 1 Can motion, 9 grades of warm-cold sensitivity scales use as warm-cold sensitivity index.9 grades of evaluation scales are at the both ends of PMV index plus "+4 Obtained by (very hot) " and " -4 (very cold) ".Aftermentioned warm-cold sensitivity detection control is carried out using the warm-cold sensitivity index.

In addition, " warm-cold sensitivity " indicates the model of " -4 "~"+4 " of warm-cold sensitivity index in the explanation of the following embodiments and the accompanying drawings 1 Enclose interior numerical value.Furthermore same, aftermentioned " average warm-cold sensitivity ", " standard warm-cold sensitivity ", " detection warm-cold sensitivity " etc. are about " cold and hot In the term of sense ", the numerical value in the range of " -4 "~"+4 " of warm-cold sensitivity index is respectively indicated.

It, will for the set temperature of the air conditioner in the warm-cold sensitivity detection control of the air conditioner of embodiment 1 " warm-cold sensitivity " conduct " standard warm-cold sensitivity " that general people's study plot is felt, by " standard warm-cold sensitivity " conduct " target warm-cold sensitivity " Carry out air conditioning control.In the warm-cold sensitivity detection control of embodiment 1, to be in " ± 0.5 " with the difference of " standard warm-cold sensitivity " Within the mode of the cold and hot sensillary area of target carry out temperature and change control and blow differentiation control.Control is changed to temperature and blows area Sub-control system is described below.In addition, then having PPD (Predicted Percentage within if it is warm-cold sensitivity index " ± 1 " Of Dissatisfied: percent dissatisfied is predicted) unsatisfied experimental result is not felt as 8 one-tenth of people.Based on the experiment knot Fruit, embodiment 1 warm-cold sensitivity detection control in, make within the difference " ± 0.5 " of " the target warm-cold sensitivity " of warm-cold sensitivity index.

In the interior as air conditioning object, in the small situation of the activity of artificial rest state and people and air tune In the state that section operating is substantially stabilized, if it is known that the difference (tcl-tr) of the surface temperature (tcl) of people and wall surface temperature (tr), It can then estimate the heat dissipation capacity (H) of the people.

If the heat dissipation capacity (H) of people and the metabolism amount (quantity of heat production M) of the people balance (H=M), the hot revenue and expenditure of the people is obtained Balance, can speculate that the people is comfortable on.On the other hand, if heat dissipation capacity (H) is bigger (H > M) than metabolism amount (quantity of heat production M), Feel cold according to degree the people of its size, if opposite heat dissipation capacity (H) is smaller than metabolism amount (H < M), can speculate that the people feels Feel heat.

Therefore, people be rest state and people activity it is small in the case where, from ambient air temperature and from as cold and hot propagated sensation The surface temperature for the thermal image information extraction people that the thermopile sensor of sensor 11 obtains and the wall surface temperature of surrounding detect the people Heat dissipation capacity (H), thus, it is possible to detect " warm-cold sensitivity " of the people in a non contact fashion.

In the air conditioner of embodiment 1, speculated in a non-contact manner in the small situation of the activity of people or people The heat dissipation capacity of people in the case where for rest state is detected " warm-cold sensitivity " of the people based on the heat dissipation capacity deduced, carries out air Adjust control.But according only to the thermal image information obtained from warm-cold sensitivity sensor 11, air conditioning subject area (is lived empty Between) people present in the determination in region (people's domain of the existence) be difficult, and then detecting is the small shape of the activity in people State is in the quiet state of people and is difficult.

Therefore, in the warm-cold sensitivity detection control of the warm-cold sensitivity detection of the air conditioner based on embodiment 1, have as follows Structure: with come since as warm-cold sensitivity sensor 11 thermopile sensor acquirement thermal image information temperature distribution information one It rises, using the human testing information of multiple infrared sensors from force-feeling sensor 10 and from about air conditioning pair As the temperature information of the other sensors in region, detect the people in air conditioning subject area there are positions, the moving type of people " warm-cold sensitivity " of state and people.

In addition, illustrating to believe using the thermal image from warm-cold sensitivity sensor 11 in the air conditioner of embodiment 1 Breath, the human testing information from force-feeling sensor 10 and come from temperature sensor (temperature sensor, surface temperature sensor Deng) temperature information (room temperature information) carry out warm-cold sensitivity detection control, but not limited to this.As air conditioning of the invention Machine is also configured to, and room temperature information is obtained from the thermal image information of warm-cold sensitivity sensor 11, using from warm-cold sensitivity sensor The air conditioning control of 11 thermal image information and the human testing information progress embodiment 1 from force-feeling sensor 10.

In addition, illustrating the small situation of the activity of artificial rest state and people in embodiment 1, that is, metabolism amount (produces Heat M) the case where regarding substantially certain value as, but activity be certain to a certain degree more than in the case where, be also configured to Metabolism amount (quantity of heat production M) corresponding with the activity is calculated, by the heat dissipation capacity H of calculated metabolism amount (quantity of heat production M) and the people It is compared, thus detects the people's sensible heat and still feel cold " warm-cold sensitivity ".

As shown in Figure 2 above, left end side is in the horizontal direction before machine 1 indoors by the force-feeling sensor 10 of embodiment 1 On be arranged and have 3 infrared sensors.Force-feeling sensor 10 is for example to be examined by detecting the infrared ray from human body radiation Survey the thermoelectric type infrared sensor that people whether there is.In the air conditioner of embodiment 1, according to force-feeling sensor's 10 The variation output pulse signal of the infrared ray amount of each infrared sensor detection, is based on the pulse signal, control unit judges that people is No presence.

In the air conditioner of embodiment 1, based on the signal exported from force-feeling sensor 10, judgement is air conditioning pair As almost motionless rest state or people carry out movable active state to the people in region.Specifically, control unit 50 according to Come in defined detection time (such as 2 minutes) from the signal that force-feeling sensor 10 exports the activity of decider size or Rest state.

In addition, in the air conditioner of embodiment 1, based on being exported from 3 infrared sensors of force-feeling sensor 10 Signal, the position of human body critical region of air conditioning subject area is divided into multiple detection zones.In the air conditioner, 3 infrared sensors of force-feeling sensor 10 are respectively structured as region overlapping that can be detected, based on from each infrared ray The signal of sensor detects people's presence or absence of multiple detection zones in air conditioning subject area.

When the activity for judging people is " small " or " rest state ", determine that the people's of each detection zone is " cold and hot Sense ", the detection processing of whole position of human body critical regions terminates.

" the air conditioning control based on warm-cold sensitivity detection "

As described above, determine the whole region (whole position of human body critical regions) of air conditioning subject area every time Implement the air conditioning control described below based on warm-cold sensitivity detection when " warm-cold sensitivity ".In addition, the sky based on warm-cold sensitivity detection The control of controlled atmosphere section is after the air conditioner starts air conditioning operating, according to the temperature information from various temperature sensors Detect implementation after the indoor temperature of air conditioning object becomes the stable state that the condition set is met certain condition. It is usual operation mode, the heat exchanger 5 of indoor unit 1 is pressure regulator when the air conditioner starts air conditioning operating 12 do not carry out pressure controlled state, the heat exchange that the first heat exchange area X and the second heat exchange area Y are unified Movement, the heat exchange for substantially carrying out single temperature act (Dan Wendu operation mode).

Figure 16 be implement in the air conditioner for indicate embodiment 1 warm-cold sensitivity detection control filtration treatment (except Judgement processing) flow chart.Filtration treatment is the processing carried out based on the thermal image information from warm-cold sensitivity sensor 11, is pair Judgement is handled except indoor people's information of each air conditioning object carries out.

In the step 101 of Figure 16, carries out " warm-cold sensitivity sensor starts to judge ", judge the room temperature of air conditioning object Whether predetermined temperature set temperature for example at that time is reached." warm-cold sensitivity sensor starts to judge " of step 101 is room temperature One of the filtration treatment controlled before reaching predetermined temperature without warm-cold sensitivity detection.In embodiment 1, make the air conditioner Set temperature at that time be as " warm-cold sensitivity sensor starts to judge " threshold value predetermined temperature.Temperature reaches rule indoors When determining temperature, start the filtration treatment (step 102) of everyone information.

In step 103, carry out " judging except warm-cold sensitivity exceptional value ", the warm-cold sensitivity index of the people of embodiment 1 it is " cold and hot Sense " is the index in the range of " ± 4 ".It but because is being controlled based on the thermal image information from warm-cold sensitivity sensor 11 Indoor " warm-cold sensitivity " of 50 simple computation air conditioning object of portion, so " warm-cold sensitivity " that is calculated as people sometimes can not Numerical value existing for energy.That is, in control unit 50, value or deficiency " -4 " more than "+4 " are being calculated as " warm-cold sensitivity " In the case where value, which is judged as YES irregular data (unwanted data), excludes the calculated result.In step 103, judgement Whether " warm-cold sensitivity " of the warm-cold sensitivity index detected be more than " -4 ", in the range of "+4 " normal value below.

In step 104, " people judges except detecting correctness " is carried out.In control unit 50, always self cooling thermal sensors 11 Two-Dimensional Heat image information, the difference based on the ambient temperature and people's regional temperature that become benchmark are extracted people's regional temperature, are calculated " warm-cold sensitivity " of the indoor people of air conditioning object.Therefore, the background waited after the measurement of warm-cold sensitivity sensor 11 just starts When the frequency in sampling of temperature is few, the detection accuracy of " warm-cold sensitivity " is reduced.Therefore, in embodiment 1 based on warm-cold sensitivity detection In air conditioning control, when frequency in sampling is few, the information is excluded.In step 104, in order to which the frequency in sampling for excluding ambient temperature is few The case where, whether judgement sampling number is defined number or more.

In step 105, carry out " judging except force-feeling sensor's detection range ".Warm-cold sensitivity detection controls and is based on coming from people The people position judging result of the human testing information realization of propagated sensation sensor 10 links.Therefore, the people carried out in force-feeling sensor 10 There is no in the region of people, indicate that the information of " warm-cold sensitivity " that calculates from thermal image information cannot act as using in the judging result of position In the information of the air conditioning control detected based on warm-cold sensitivity.Therefore, such calculating knot for indicating " warm-cold sensitivity " is excluded Fruit.In step 105, in the people position judging result that force-feeling sensor 10 carries out, being not present, the region detection of people is " cold and hot When sense ", the information is excluded.

In step 106, carry out " judging except warm-cold sensitivity sensor detection range ".Warm-cold sensitivity sensor 11 is that thermoelectric pile passes Sensor, therefore the position more than at a distance not can be carried out the detection of correct " warm-cold sensitivity ".Thus, for example to calculating The ground distance artificially only of " warm-cold sensitivity " be more than it is defined apart from when, it is believed that its " warm-cold sensitivity " is incorrect, excludes in this case Calculated result.In addition, area shared by people in thermal image information is greatly without can be carried out correctly when people position is excessively close The detection of " warm-cold sensitivity ".Therefore, in the horizontal plane of the position of the test section relative to force-feeling sensor 10, by its test section and people When the line segment angulation of placement of foot (ground) connection of body is more than defined angle, face shared by the people in thermal image information Product becomes larger, it is believed that the detection that not can be carried out correct " warm-cold sensitivity " excludes the calculated result in such situation.In step 106, example Such as determine calculating " warm-cold sensitivity " ground distance artificially only whether be as defined within distance, and relative to force-feeling sensor The horizontal plane of the position of 10 test section, the line segment angulation by the connection of the placement of foot (ground) of its test section and human body are No is within defined angle.

" region of people's information is distributed " is carried out in step 107.Step 103 so far~106 filtration treatments (except at judgement Reason) in, people's information (information of " warm-cold sensitivity " of people) after filtration treatment is assigned to indoor multiple people of air conditioning object Body position critical region is converted into " warm-cold sensitivity " of each the people body position critical region.In addition, existing in same area more In the case where personal information, using the average value of " warm-cold sensitivity " in the region as " warm-cold sensitivity (the average warm-cold sensitivity) " in the region.

In addition, not corresponding people's information (information of " warm-cold sensitivity " of people) is discarded in step 103~106.Step 109 In, the case where confirming the filtration treatment of the people's information detected terminates, each position of human body being transferred to next time is sentenced Filtration treatment (the step 110) in other region.

" people judges except position " is carried out in step 111.Warm-cold sensitivity sensor 11 is thermopile sensor, it is thus possible to will Identification is people to motionless heat source (such as TV, landing floor lamp etc.), and error detection occurs.Therefore, in step 111, with come from The human testing information contrast of the force-feeling sensor 10 of the movement of people is detected, " warm-cold sensitivity " detected is in human testing information There is no the measurement results in the case where the region of people, excluding warm-cold sensitivity sensor 11 at this time.In step 111, judge cold In the corresponding region of " warm-cold sensitivity " that is detected in the thermal image information of thermal sensors 11, whether deposited in human testing information In people, in the case where arriving " warm-cold sensitivity " there is no the region detection of people in human testing information, discarded detection information at this time.

" judging except block activity " is carried out in step 112.The air tune based on warm-cold sensitivity detection of present embodiment 1 In section control, the state of the rest state of people or the activity " small " of people is set to the finger of warm-cold sensitivity index as benchmark Number.Therefore, when people in air conditioning subject area carries out activity (activity > is small) above to a certain degree, from based on coming from The control of the detection of " warm-cold sensitivity " of the people that the thermal image information of warm-cold sensitivity sensor 11 carries out is switched to using from people's propagated sensation The human testing information of sensor 10 based on people detect stoichiometric number speculate people activity (" big ", " in ", " small " or " quiet shape State ") control.Specifically, the variation pair based on the infrared ray amount with the detection of each infrared sensor of force-feeling sensor 10 The signal answered judges that people whether there is, interior in the inspection of each position of human body critical region based on the stipulated time (such as 2 minutes) at this time Measure people existing people detect stoichiometric number, thus it is speculated that people activity (" big ", " in ", " small " and " rest state ").

As described above, in step 112, the activity of people is judged based on the human testing information from force-feeling sensor 10 Whether be lower than " in ".That is, it is judged that whether the activity of people is " small " (including " rest state ") below.Judge in step 112 In the case that activity for people is " small " or " rest state ", in step 113, determine that the people's in each region is " cold and hot Sense ", the filtration treatment of whole region terminates (step 115).

The filtration treatment of the whole region of the warm-cold sensitivity detection of above-mentioned step 101~115 is utilizing cold and hot propagated sensation every time Sensor 11 carries out when obtaining thermal image information, and " warm-cold sensitivity " of whole region is always accurately slapped in the air conditioner It holds and determines.

Figure 17 is the flow chart for indicating the air conditioning control based on the warm-cold sensitivity detected as described above.Figure 17's In step 201, judge whether " warm-cold sensitivity " that detects is divided into multiple detection zones, i.e., whether there is in multiple detection zones People.In the case that " warm-cold sensitivity " that detects is present in multiple detection zones, judgement detects the presence of people in step 202 Multiple detection zones " warm-cold sensitivity " difference whether more than specified value.If the difference of " warm-cold sensitivity " of multiple detection zones is More than specified value, then it is judged as that needs blow differentiation control, the driving pressure adjuster in a manner of becoming two temperature operation mode 12 (steps 203).For example, making pressure regulator 12 carry out decompression movement, so that the first heat exchange area in heating movement X carries out the heat exchange of high-temperature (such as 35~55 DEG C), temperature (regulation temperature lower than high-temperature in the second heat exchange area Y progress The temperature of degree) heat exchange.The temperature of the first heat exchange area X and the second heat exchange area Y of heat exchanger 5 at this time are in temperature Degree sensor 18a, 18b (referring to Fig. 4) is detected and is entered control unit 50, controls for air conditioning.

In step 204, according to the difference of " warm-cold sensitivity " judged in step 202, corresponding detection zone is implemented Differentiation control (wind direction control and air quantity are blowed by what upper and lower wind direction blinds 30, left and right wind direction blinds 40 and indoor fan 6 were implemented Control).That is, control unit 50 controls wind direction and/or air quantity, so that " warm-cold sensitivity " of each individual in the region detected is phase Together, and/or for according to " the standard warm-cold sensitivity " of set temperature decision at this time.For example, the region different to " warm-cold sensitivity ", makes Lower wind direction blinds 30 and the rotation of left and right wind direction blinds 40 are to change separated blowout ratio, so that the difference of " warm-cold sensitivity " is specified value Within (such as 0.5).

In addition, " standard warm-cold sensitivity " refers to common people's feeling when room temperature is set temperature in embodiment 1 " warm-cold sensitivity ".For example, set temperature common people feels when being 20 DEG C " standard warm-cold sensitivity " is substantially " -1 ", set temperature " the standard warm-cold sensitivity " that common people feels when being 25 DEG C is substantially "+1 ".It can also be according to season in addition, being somebody's turn to do " standard warm-cold sensitivity " Section changes.

On the other hand, in step 201, " warm-cold sensitivity " detected is not divided into multiple regions, and exists in 1 region In the case where multiple people, " average warm-cold sensitivity " (step 205) there are the region of multiple people is calculated.It is " average cold and hot about this Sense " calculates " average cold in each region in above-mentioned step 202 there are being equally applicable when multiple " warm-cold sensitivities " in each region Thermal sensation ".

In step 206, judge calculated " average warm-cold sensitivity " and set temperature decision at this moment " standard is cold and hot Whether the difference of sense " is more than specified value, for example whether being more than " ± 1 ".Corresponding region " average warm-cold sensitivity " with " standard is cold In the case that the difference of thermal sensation " is specified value or more, make change to the wind direction and/or air quantity of air conditioning subject area, and/or So that target temperature is changed (temperature change control), Lai Jinhang air conditioning controls (step 207) so that " average warm-cold sensitivity " with The difference of " standard warm-cold sensitivity " is in the cold and hot sensillary area of target within " ± 0.5 ".

The air conditioning control of above-mentioned steps 201~207 is carried out in each stipulated time, based on according to the activity of people Air conditioning control is implemented in warm-cold sensitivity detection.Therefore, whens the presence disappearance etc. of people, can also terminate to detect based on above-mentioned warm-cold sensitivity Air conditioning control.

In addition, as the thermal image information of control unit is sent to from the warm-cold sensitivity sensor 11 of embodiment 1, including detect The quantity of people, the data such as position and " warm-cold sensitivity ".

" control is distinguished in blowing for air conditioner "

In the air conditioner of embodiment 1, as described above, based on the human testing information from force-feeling sensor 10 With the thermal image information etc. from warm-cold sensitivity sensor 11, it is determined as indoor people's domain of the existence of air conditioning object, base " warm-cold sensitivity " of detection the people is inferred in the amount of radiation of the people of people's domain of the existence, and common people is become in the temperature of setting with the people Feel that the mode of " the standard warm-cold sensitivity " of " comfortable " carries out air conditioning control.

The air conditioner of embodiment 1 is as described above, have upper and lower wind direction blinds 30 and left and right wind direction blinds 40, up and down Wind direction blinds 30 is made of the multiple vane plates for changing the wind direction of blowout in above-below direction, and left and right wind direction blinds 40 is blown out by making Multiple vane plates for changing in left and right directions of wind direction constitute.In addition, wind direction blinds 30 is upper layer vane plate 31, middle layer leaf up and down The upper, middle and lower 3-tier architecture of sheet 32 and lower leave plate 33, middle layer vane plate 32 are divided into 2 parts in the center of its left and right directions (middle layer lobus sinister sheet 32a, middle layer lobus dexter sheet 32b).Left and right wind direction blinds 40 is left with upside left and right blade 40a and downside 2 layers of structure up and down of lobus dexter piece 40b, upside left and right blade 40a are configured between upper layer vane plate 31 and middle layer vane plate 32 The upside of formation blows out region FA (the first blow-off outlet), and downside left and right blade 40b is configured at vane plate 32 in middle level and lower layer's leaf Downside blowout region BA (the second blow-off outlet) formed between sheet 33.Moreover, upside left and right blade 40a and downside left and right blade 40b is each separated into the blade group that left and right is divided into 2 parts, so that separately blowing out in the lateral direction.

As described above in the air conditioner of embodiment 1, blow-off outlet 2b points blow out region FA (the first blowout for upside Mouthful) and downside blow out region BA (the second blow-off outlet) 2 layers blow-off outlet up and down, and each lower regions are separately blown to the left and right Out.Therefore, based on according to the human testing information from force-feeling sensor 10 and the letter of the thermal image from warm-cold sensitivity sensor 11 " warm-cold sensitivity " that detects of the people of people's domain of the existence and the people's domain of the existence that breath etc. determines, control unit carry out wind direction blinds Component 3 blows differentiation control.

Hereinafter, illustrating the concrete example for blowing differentiation control of the wind direction louver assembly 3 of the air conditioner of embodiment 1 " 1 "~" 5 ".In addition, example " 1 "~" 4 " described below, are the indoor left and right in warming operation in air conditioning object Region is respectively present the case where 1 people, is to blow differentiation control based on what each personal " warm-cold sensitivity " that detects carried out.In addition, Example " 5 " be in warming operation the case where there are 1 people for the interior of air conditioning object, be the people activity more than situation With it is few in the case where blow differentiation control.

[1] firstly, being that control unit 50 is judged as in the room of air conditioning object in air conditioner as concrete example 1 Two people existing for interior left and right region feel the case where " comfortable ".At this point, by the first heat exchange area X and the second heat exchange zone The pressure regulator 12 of the refrigerant pipe setting connected between the Y of domain is set as without pressure controlled state, heat exchanger 5 Become " Dan Wendu operation mode " with the function as a heat exchange.At this point, being blown out from the upside of wind direction louver assembly 3 Region FA and downside blowout region BA blows out the air of substantially the same temperature, upside left and right blade 40a and downside left and right leaf Piece 40b continues the wobbling action of left and right respectively.Or, or it blows out towards left and right region existing for people, upside lobus sinister Region of the piece 41a and downside lobus sinister piece 42a towards left side, the area of upside lobus dexter piece 41b and downside lobus dexter piece 42b towards right side Domain is divided into all directions rotation, blowout movement is carried out in the state of being fixed on the position.

[2] air conditioner as concrete example 2 is that control unit 50 is judged as and is present in the indoor of air conditioning object The difference of " warm-cold sensitivity " of the people in left and right region be " ± 1 " more than situation, and be judged as left side region people feel " cold ", The people in the region on right side feels the case where " comfortable ".At this point, pressure regulator 12 is set as decompression state.As a result, heat is handed over Parallel operation 5 becomes in the first heat exchange area X and the second heat exchange area Y heat exchange into different temperature (high-temperature and middle temperature) " two temperature operation mode ".Therefore, to blow from the upside of wind direction louver assembly 3 at this time blowout region FA the region on right side The air of middle temperature out, and from downside blowout region BA to the mode of the air of left area blowout high-temperature, setting upside The blow-off direction of left and right blade 40a and downside left and right blade 40b.In addition, in this way in the case where setting, in the experiment of inventor, The surface temperature of right area and left area poor (temperature of ground 10cm) is 3 DEG C.

[3] air conditioner as concrete example 3 is that control unit 50 is judged as and is present in the indoor of air conditioning object The difference of " warm-cold sensitivity " of the people in left and right region is the situation of " ± 1 " or more, and is to be judged as that the people of left area feels " cold ", the right side The people of side region feels the case where " slightly hot ".At this point, pressure regulator 12 is set as decompression state, heat exchanger 5 becomes " dual temperature Spend operation mode ".With the air from the downside of wind direction louver assembly 3 at this time blowout region BA to left area blowout high-temperature Mode, setting downside left and right blade 40b blow-off direction.In turn, the air for the middle temperature that blowout region FA is blown out from upside Left area is blown out using the upside lobus sinister piece 41a of upside left and right blade 40a, using upside lobus dexter piece 41a to right area Blowout.That is, the upside left and right blade 40a of upside blowout region FA is set in a manner of to blowout of dividing right and left.It sets in this way In the case of, in the experiment of inventor, the surface temperature difference of right area and left area is 5 DEG C.

[4] air conditioner as concrete example 4 is the indoor left and right area that control unit 50 is judged as air conditioning object The difference of " warm-cold sensitivity " of the people in domain is the situation of " ± 1 " or more, and is to be judged as that the people of left area feels " cold ", right area People feel " heat " the case where.At this point, pressure regulator 12 is set as decompression state, heat exchanger 5 becomes " two temperature operational mode Formula ".In a manner of from air of the downside of the wind direction louver assembly 3 at this time blowout region BA to left area blowout high-temperature, The blow-off direction of setting downside left and right blade 40b.Similarly, with the air of the middle temperature blown out from upside blowout region FA to a left side The mode of side region blowout, direction of both setting upside left and right blade 40a to left area blowout.The case where setting in this way Under, in the experiment of inventor, the surface temperature difference of right area and left area is 8 DEG C.

[5] air conditioner as concrete example 5, there is only 1 people for the interior of the air conditioning object in warming operation In the case where implement " two temperature operation mode ".In concrete example 5, be divided into people indoors activity it is more when (when amount of movement is more) With it is few when (amount of movement few when) carry out blowing differentiation control.

In the case that the amount of movement of people is more, the air of the high-temperature of the downside blowout region BA from wind direction louver assembly 3 It is blown out to region existing for the people.Meanwhile it is dynamic be swung left and right positioned at the upside left and right blade 40a of upside blowout region FA The mode of work is by drive control, so that the room of the air-air controlled plant from the upside blowout region FA middle temperature blown out Interior whole blowout.As a result, being able to carry out and implementing on one side in the case that the amount of movement of the indoor people of air conditioning object is more The heating at people center carries out the whole heating in interior on one side and inhibits the sky of the indoor temperature unevenness of air conditioning object Controlled atmosphere section.
