Detailed description of the invention
Suitable reference accompanying drawing is described in detail embodiments of the present invention.It should be noted that, the part shared in the various figures marks same symbol, and the repetitive description thereof will be omitted.
(the first embodiment)
Fig. 1 is the loop structure figure of the air regulator of the first embodiment.When cooling operation, from compressor 34 spray high temperature and the cold-producing medium of high pressure flow into outdoor heat exchanger 37 via cross valve 35.Flow into cold-producing medium in outdoor heat exchanger 37 and carry out heat exchange with the air of the outdoor transported by outdoor blower fan 38, thus condensation and become liquid refrigerant.Liquid refrigerant becomes the two-phase system cryogen of low-temp low-pressure by expansion valve 36 and flows into indoor heat converter 5.The two-phase system cryogen flowing into the low-temp low-pressure in indoor heat converter 5 carries out heat exchange with the air of the indoor transported by indoor blower fan 6.Now, the air being transported to the indoor in indoor heat converter 5 by the two-phase refrigerant cools of low-temp low-pressure flow in indoor heat converter 5, and from blow-off outlet 3 to indoor ejection.Temperature from from blow-off outlet 3 to the air of the air ratio suction inlet 2 of indoor ejection is low, therefore, it is possible to make indoor temperature reduce.Cold-producing medium carry out heat exchange in indoor heat converter 5 after returns to compressor 34 again via cross valve 35.
Compressor 34, outdoor heat converter 37, outdoor blower fan 38 and expansion valve 36 are configured at off-premises station, and indoor heat converter 5 and indoor blower fan 6 are configured at indoor set 1.
Fig. 2 is the sectional view along side of the indoor set of the first embodiment.The indoor set 1 of air regulator possesses: the air flue 4 suction inlet and blow-off outlet 3 linked; Escutcheon 13; Be fixed on escutcheon 13, and be configured in the decorative panel 12 before indoor set.Further, the indoor set 1 of air regulator possesses in the inside of decorative panel 12 and escutcheon 13: the indoor heat converter 5 being configured at air flue 4; The filter 14 be made up of front face side filter 14a and top side filter 14b, wherein, this front face side filter 14a is between decorative panel 12 and indoor heat converter 5, and this top side filter 14b is positioned at the below of upper decoration frame 13a.Be configured with immediately below the filter 14b of top side with remove dust after air carry out the indoor heat converter 5 of heat exchange, remove the air after dust by filter 14 and flow to the indoor heat converter 5 of Λ shape (inverted V-shaped shape).The suction inlet 2 of the air in suction chamber is positioned at the top (top of decorative panel 12 and top side filter 14b) of indoor set 1 main body, and the air sucked from suction inlet 2 flows to the top side filter 14b removing dust.
Be provided with blow-off outlet 3 in the below of decorative panel 12, the air after heat exchange blows out from blow-off outlet 3 to the front of indoor set 1.Indoor blower fan (air blast axial-flow fan) 6, towards in the air flue 4 of blow-off outlet 3, being configured in the downstream of indoor heat converter 5 via indoor heat converter 5 from suction inlet 2, blows out the air after heat exchange from blow-off outlet 3.
Casing 15 is fixed on wall.The drain pan 16 of the water being received in condensation in indoor heat converter 5 is configured with in the downside of indoor heat converter 5.By casing 15 and drain pan 16, be configured for the downstream wind-tunnel 17 of the air flue 4 in the downstream producing fan 6.
Be configured with side body 18 in the upside of downstream wind-tunnel 17, be configured with lower side body 11 in downside.Upper side body 18 forms the top of blow-off outlet 3, and lower side body 11 forms the bottom of blow-off outlet 3.
In addition, the end face of the side contrary with fan 6 side of downstream wind-tunnel 17 becomes blow-off outlet 3.The upside up-down wind direction board 9 of left and right wind direction board 33, the downside up-down wind direction board 10 being configured in the downside of downstream wind-tunnel 17 and the upside that is configured in downstream wind-tunnel 17 is configured at blow-off outlet 3.At this, the situation being configured at blow-off outlet 3 comprises the situation of the downstream wind-tunnel 17 of the vicinity being configured at blow-off outlet 3.Downside up-down wind direction board 10 under the control of control part, operate stop time close blow-off outlet 3, when cooling operation or warming operation time open blow-off outlet 3.
Because upside up-down wind direction board 9 is configured in wind path, therefore when cooling operation, can not produce temperature difference in the air that upper surface and the lower surface of upside up-down wind direction board 9 flow through, therefore up-down wind direction board 9 can not condense.
On the other hand, downside up-down wind direction board 10 produces temperature difference at upper surface and lower surface, therefore produces condensation.Thus, in order to prevent the downside upper surface of up-down wind direction board 10 and the heat trnasfer of lower surface, downside up-down wind direction board 10 clips the heat-barrier material 28 of the large polyurethane of thermal resistance etc. and forms.
Then, Fig. 3, Fig. 4 action to up-down wind direction board is used to be described.Amplification side view cutaway drawing when Fig. 3 is the ability mode of priority of the indoor set blow-off outlet of the first embodiment.For ability mode of priority, when cooling operation or warming operation time design temperature and the difference of indoor temperature large, need to use when large refrigerating capacity or heating capacity.
Such as, when the running of cooling operation or warming operation starts design temperature and room temperature exist specify more than poor time use.Refrigerating capacity and heating capacity are determined by suction inlet 2 and the temperature difference of blow-off outlet 3 and the long-pending of air quantity, and the situation that air quantity is many makes refrigerating capacity, heating capacity improves further.Now, rise by making the rotating speed of indoor blower fan 6 and air quantity is increased, but noise also rises simultaneously.That is, if blowing efficiency can be made to improve, then ability can be made to increase with low noise.
When ability mode of priority, downside up-down wind direction board 10 is rotated centered by the axle 21 of downside up-down wind direction board, on the extended line making the upstream-side-end upper surface 26a of downside up-down wind direction board 10 be configured in lower side body 11 or than the extended line position on the lower of lower side body 11.Thus, can be reduced by the cold wind 22 of downstream wind-tunnel 17 or the air blast resistance of warm braw 23, thus efficiency can send cold wind 22 or warm braw 23 to indoor well when not reducing blowout air quantity.For upside up-down wind direction board 9 and downside up-down wind direction board 10, rotated centered by the axle 21 of the axle 20 of upside up-down wind direction board and downside up-down wind direction board by the driver part 25 of stepping motor 24 grade.The upper surface of downside up-down wind direction board 10 refers to the face of upside up-down wind direction board 9 side in the up-down wind direction board 10 of downside.
For lower side body 11 and downside up-down wind direction board 10 along side cross sectional shape for, as long as downside up-down wind direction board 10 is on the roughly extended line of lower side body 11, can be rectilinear form, also can be curve shape.It should be noted that, preferably the upstream-side-end upper surface 26a of downside up-down wind direction board 10 configures in the mode become on the extended line of lower side body 11.
Because downside up-down wind direction board 10 rotates centered by up-down wind direction board axle 21, therefore downside up-down wind direction board 10 and lower side body 11 need the gap of the degree do not interfered.Gap needs for more than the deviation of the product size of downside up-down wind direction board 10 or the management value of warpage, but in order to be used as diffuser by downside up-down wind direction board 10, preferred gap is as far as possible little.When the gap is large, cold wind 22 or warm braw 23 can spill from gap portion, and the dynamic pressure being originally used as static pressure recovery can apply kinetic energy to ambient air, thus effectively cannot carry out static pressure recovery.
When gap is very little, according to Bernoulli's theorem, blow-off outlet 3 is less than the pressure of the surrounding of indoor set 1, and therefore clearance portion branch produces the flowing (from below flowing) upward of the inflow air 39 flowed into blow-off outlet 3.
But when the clearance increases, the flowing that the cold wind 22 flowed along lower side body 11, warm braw 23 will spread surpasses the flowing flowed into blow-off outlet 3, and cold wind 22 or warm braw 23 can spill from gap portion, thus apply kinetic energy to ambient air.In addition, be also applied in kinetic energy owing to flowing into air 39, therefore preferably flow into air 39 few.According to above reason, expect that described gap is little, and in order to effectively carry out static pressure recovery, preferred gap is below 2mm.
It should be noted that, for upside up-down wind direction board 9, in order to reduce air blast resistance, being preferably formed to the posture almost parallel with downside up-down wind direction board 10.
Amplification side view cutaway drawing when Fig. 4 is the usual cooling operation pattern of the indoor set blow-off outlet of the first embodiment.Usual cooling operation pattern uses when the humidity of the situation or room air that do not need large refrigerating capacity is high.Although clip the heat-barrier materials 28 such as the large polyurethane of thermal resistance in downside up-down wind direction board 10, but when for a long time when the upper surface of downside up-down wind direction board 10 and lower surface produce temperature difference or when the high state of humidity continues, downside up-down wind direction board 10 also may condense.
Therefore, in the present embodiment, when the difference of design temperature and room temperature is below setting, or when humidity is more than setting, become usual cooling operation pattern, be positioned to make the upstream-side-end upper surface 26a of downside up-down wind direction board 10 and configure downside up-down wind direction board 10 than the mode of the extended line position by the top of lower side body 11.Downside up-down wind direction board 10 in usual cooling operation pattern and the distance between lower side body 11 are than the downside up-down wind direction board 10 in ability mode of priority and the distance between lower side body 11.
The air that temperature is low easily rests on indoor lower position.When the air of low temperature rests on indoor lower position, user only underfooting turns cold, and may bring sense of discomfort to user.When usual cooling operation pattern, expect the high position blowing cold air 22 from the indoor set 1 of air regulator to indoor, indoor overall temperature is declined.Therefore, the position of the position after 5 ~ 25 ° as the downside up-down wind direction board 10 during usual cooling operation pattern is rotated centered by the axle 21 of downside up-down wind direction board upward from the position of the downside up-down wind direction board 10 during ability mode of priority.For upside up-down wind direction board 9, in order to reduce air blast resistance, be preferably formed to the posture almost parallel with downside up-down wind direction board 10.
The downstream of side body 11 under upstream-side-end 26 position of downside up-down wind direction board.Now, owing to arranging the gap of regulation between downside up-down wind direction board 10 and lower side body 11, the flowing that therefore cold wind 22 will spread surpasses the flowing flowing into air 39.Thus, cold wind 22 flows along lower side body 11, and the separately flowing to the upper side and lower side of downside up-down wind direction board 10 by the upstream-side-end 26 of downside up-down wind direction board.Because cold wind 22 also flows to the downside of downside up-down wind direction board 10, therefore, the upper side and lower side of downside up-down wind direction board 10 is all cooled roughly equably.Thereby, it is possible to suppress the condensation to the surface of downside up-down wind direction board 10.
The axle 21 of downside up-down wind direction board at the upstream side of downside up-down wind direction board 10 between upper side body 18 and lower side body 10.Distance between the axle 21 of downside up-down wind direction board and downside up-down wind direction board 10 is than the downside up-down wind direction board 10 in usual cooling operation pattern and the distance between lower side body 11.Specifically, the gap preferably between the upstream-side-end 26 of downside up-down wind direction board 10 and lower side body 11 is 5 ~ 15mm.Thus, when usual cooling operation pattern, easily cold wind 22 is also supplied to the downside of downside up-down wind direction board 10.
For downside up-down wind direction board 10, on the downside of the upstream-side-end of downside up-down wind direction board, 26b can be formed as fillet surface or curve form.Thus, when usual cooling operation pattern, cold wind 22 non-resistance flowed in the downside along downside up-down wind direction board 10 and flowing more swimmingly.
For downside up-down wind direction board 10, be hollow-core construction, also can for possessing the structure of heat-barrier material 28 in inside.Thereby, it is possible to improve the inhibition to the condensation on downside up-down wind direction board 10 surface.
The switching of ability mode of priority and usual cooling operation pattern is implemented by user.In addition, when the humidity that the humidity sensor 32 that the indoor set 1 by air regulator possesses detects reaches humidity (setting) that preset, can automatically switching capability mode of priority and usual cooling operation pattern.Also or humidity sensor 32 can be replaced on humidity sensor 32 basis, and come switching capability mode of priority and usual cooling operation pattern according to the detected value of temperature sensor 31.
Need after running has just started, do not produce condensation and indoor are turned cold fast, therefore operate stipulated time of having started detected value regardless of humidity sensor 32 or humidity sensor 32, can executive capability mode of priority forcibly.
It should be noted that, in ability mode of priority, the rotating speed of indoor blower fan 6 can be changed to the value of regulation, also can the switching of usual cooling operation pattern of handling capacity mode of priority the rotating speed of indoor blower fan 6 not changed.
Ability mode of priority and usual cooling operation pattern may not be defined as the situation forming the specific operation mode that user can set, also can form as follows: in a cooling operation pattern, according to the value detected by temperature sensor 31 or humidity sensor 32, the position of downside up-down wind direction board 10 is switched to the position of the side up-down wind direction board 10 in the position of the downside up-down wind direction board 10 in ability mode of priority and usual cooling operation pattern.
Like this, according to first embodiment of the invention, in the indoor set 1 of air regulator, while possessing the ability mode of priority making room air efficiency turn cold well, when the humidity of room air is significantly high, the condensation on wind direction board 10 surface up and down can be suppressed by usual cooling operation pattern.
The sectional view along side when Fig. 5 is the running stopping of the indoor set of the first embodiment.Upside up-down wind direction board 9 in present embodiment and downside up-down wind direction board 10 are formed as curve shape in the mode of the framework along indoor set 1.Therefore, when the running of air regulator stops, the lower surface of upside up-down wind direction board 9 and downside up-down wind direction board 10 becomes a part for the outward appearance of indoor set 1, thus can be formed as the also excellent structure in outward appearance aspect.
When the running of air regulator stops, as shown in Figure 5, the lower surface of downside up-down wind direction board 10 becomes the part on the surface of the design outward appearance forming indoor set 1, the position shown in Fig. 4 is become in order to make downside up-down wind direction board 10 when usual cooling operation pattern, and make downside up-down wind direction board 10 become the position shown in Fig. 3 when ability mode of priority, the axle 21 of the downside up-down wind direction board rotated for downside up-down wind direction board 10 is being configured between lower side body 11 and upper side body 18 than the position of downside up-down wind direction board 10 by weather side.
As diffuser, when being recovered as object with static pressure, downside up-down wind direction board 10 is more long more can obtain effect, but owing to being separated with the axle 21 of downside up-down wind direction board, therefore needs large torque to make up-down wind direction board 10 rotate.When the torque deficiency of the stepping motor 24 making downside up-down wind direction board 10 rotate, if via decelerator, torque can be made to increase, but the larger then decelerator of speed reducing ratio is larger.That is, when downside up-down wind direction board 10 is used as diffuser, for can obtaining the structure of the effect of diffuser to greatest extent, can be contained in the size of indoor set 1 to increase speed reducing ratio with decelerator, and on the downside of making, up-down wind direction board rises to the upper limit of the torque that downside up-down wind direction board 10 can be made to rotate.It should be noted that, stepping motor 24 and decelerator also can be made to be positioned at the rear side of lower side body 11 and the top of bottom escutcheon 13b.Stepping motor 24 and decelerator can be avoided to become the obstacle of air-flow, make the torque of the axle 21 of downside up-down wind direction board increase simultaneously.It should be noted that, the rear side of lower side body 11 refers to the space of the rear side of downstream wind-tunnel 17.
(the second embodiment)
Second embodiment and the first embodiment difference are, the lower side body 11 of the second embodiment has the first rake 29 and is positioned at the second rake 30 of the position than the first rake 29 downstream (front).Second rake 30 is compared with the first rake 29, and front tilts to floor direction.
Then, the action of Fig. 6 to Fig. 8 to the up-down wind direction board of the second embodiment is used to be described.Amplification side view cutaway drawing when Fig. 6 is the ability mode of priority of the indoor set blow-off outlet of the second embodiment.When ability mode of priority, downside up-down wind direction board 10 is rotated centered by the axle 21 of downside up-down wind direction board, on the extended line making the upper surface of downside up-down wind direction board 10 be positioned at the first rake 29 of described lower the side body 11 or extended line position be on the lower positioned at than described lower side body.Thus, by the air blast drag reduction of the cold wind 22 after the heat exchange of downstream wind-tunnel 17 or warm braw 23, therefore, it is possible to efficiency sends cold wind 22 or warm braw 23 well to indoor when not reducing blowout air quantity.For upside up-down wind direction board 9 and downside up-down wind direction board 10, same with the first embodiment, rotated by driver part such as stepping motor 24 grade 25.
For the first rake 29 of lower side body 11 and downside up-down wind direction board 10 along side cross sectional shape for, as long as downside up-down wind direction board 10 is on the roughly extended line of the first rake 29 of lower side body 11, can be rectilinear form, also can be curve shape.Now, for the gap between the upstream-side-end 26 of downside up-down wind direction board and the first rake 29 of lower side body 11, preferably same with the first embodiment, less and be below 2mm.
For upside up-down wind direction board 9, in order to reduce air blast resistance, be also preferably formed to the posture almost parallel with downside up-down wind direction board 10.
Amplification side view cutaway drawing when Fig. 7 is the usual cooling operation pattern of the indoor set blow-off outlet of the second embodiment.Usual cooling operation pattern uses when the humidity of the situation or room air that do not need large refrigerating capacity is high.
Same with the first embodiment, rotate the position of the position after 5 ~ 25 ° as the downside up-down wind direction board 10 during usual cooling operation pattern by centered by the axle 21 of downside up-down wind direction board upward from downside up-down wind direction board 10 position during ability mode of priority.For upside up-down wind direction board 9, in order to reduce air blast resistance, be preferably formed to the posture almost parallel with downside up-down wind direction board 10.
The upstream-side-end upper surface 26a of downside up-down wind direction board is positioned at the extended line position by the top of the first rake 29 than lower side body 11.Therefore, for the cold wind 22 that the first rake 29 along lower side body 11 flows, the separately flowing to the upper side and lower side of downside up-down wind direction board 10 by the upstream-side-end 26 of downside up-down wind direction board.Now, a part for cold wind 22 is under the effect of wall attachment effect, more effectively flow to the downside of downside up-down wind direction board 10 from the first rake 29 along the downside of the second rake 30, downside up-down wind direction board 10 than the first embodiment, therefore, the upper side and lower side of downside up-down wind direction board 10 is all cooled roughly equably.Thereby, it is possible to suppress the condensation to the surface of downside up-down wind direction board 10.

For downside up-down wind direction board 10, on the downside of the upstream-side-end of downside up-down wind direction board, 26b can be formed as fillet surface or curve form.Thus, when usual cooling operation pattern, the cold wind 22 flowed in the downside along downside up-down wind direction board 10 is flowed without resistance more swimmingly.
For described downside up-down wind direction board 10, be hollow-core construction, also can for possessing the structure of heat-barrier material 28 in inside.Thereby, it is possible to improve the inhibition to the condensation on downside up-down wind direction board 10 surface.
Amplification side view cutaway drawing when Fig. 8 is the usual warming operation pattern of the indoor set blow-off outlet of the second embodiment.Usual warming operation pattern uses close to when design temperature in the temperature of the situation or room air that do not need large heating capacity.The air that temperature is high easily rests on indoor high position.When the air of high temperature rests on indoor high position, the air near the head of user becomes high temperature, does not warm in the underfooting of user, thus may bring sense of discomfort.When usual warming operation pattern, expect the lower position blowout warm braw 23 from the indoor set 1 of air regulator to indoor, warm from the underfooting of user.Therefore, when usual warming operation pattern, described downside up-down wind direction board 10 is rotated centered by the axle 21 of downside up-down wind direction board, on the extended line making the upper surface of described downside up-down wind direction board 10 be configured in the second rake 30 of described lower side body 11 or than the extended line position on the lower of the second rake 30.Downside up-down wind direction board 10 position expecting now becomes rotates the position after 5 ~ 30 ° downwards from downside up-down wind direction board 10 position during described ability mode of priority centered by axle.For upside up-down wind direction board 9, expect to be formed as the posture almost parallel with downside up-down wind direction board 10.
Warm braw 23 flows along lower side body 11, through the first rake of lower side body, the second rake of lower side body and upper surface along downside up-down wind direction board 10 under effect in wall attachment effect flows, and to the lower position blowout warm braw 23 of indoor.
Downside up-down wind direction board 10 is configured on the extended line of lower side body 11 as diffuser, but upside up-down wind direction board 9 is configured on the extended line of upper side body 18, the effect as diffuser can be obtained too.But, because cold wind 22, warm braw 23 flow along lower side body 11, the effect as diffuser equal with downside up-down wind direction board 10 therefore cannot be obtained.
When the running of air regulator stops, as shown in Figure 5, the lower surface of downside up-down wind direction board 10 becomes a part for the outward appearance of indoor set 1, the position shown in Fig. 4 or Fig. 7 is become in order to make downside up-down wind direction board 10 when usual cooling operation pattern, make downside up-down wind direction board 10 become the position shown in Fig. 3 or Fig. 6 when ability mode of priority, make downside up-down wind direction board 10 become the position shown in Fig. 8 when usual warming operation pattern, and the axle 21 of the downside up-down wind direction board rotated for downside up-down wind direction board 10 is being configured between lower side body 11 and upper side body 18 than the position of downside up-down wind direction board 10 by weather side.
Same with the first embodiment, the switching of ability mode of priority, usually cooling operation pattern and usually warming operation pattern is implemented by user.In addition, when the room temperature that the temperature sensor 31 that the indoor set 1 by air regulator possesses and humidity sensor 32 detect and humidity reach the room epidemic disaster preset, can automatically switching capability mode of priority, usually cooling operation pattern and usually warming operation pattern.
When cooling operation starts, ability mode of priority design temperature and room temperature exist specify more than poor time use, if regulation temperature difference within, then become usual cooling operation pattern.
From ability mode of priority to the transformation of usual cooling operation pattern when the difference of design temperature and room temperature is below the value that specifies, or carry out when in official hour, humidity is more than the value of regulation, the position of up-down wind direction board becomes the position of the up-down wind direction board of usual cooling operation pattern, flow through wind at the lower surface of downside up-down wind direction board 10 and make upper surface and lower surface there is no temperature difference, preventing condensation thus.
Ability mode of priority when warming operation starts design temperature and room temperature exist specify more than poor time use, if regulation temperature difference within, then become usual warming operation pattern.
Carry out from ability mode of priority to the transformation of usual warming operation pattern when the difference of design temperature and room temperature becomes below the value of regulation, the position of up-down wind direction board becomes the position of the up-down wind direction board of usual warming operation pattern, from the indoor set 1 of air regulator to the lower position of indoor blowout warm braw 23, warmed in the underfooting of user.
By the second embodiment, in the indoor set 1 of air regulator, while possessing and making room air efficiency turns cold well or efficiency warms well ability mode of priority, during the significantly high cooling operation of the humidity of room air, can by the condensation on usual cooling operation mode suppression wind direction board 10 surface up and down.And, when usual warming operation pattern, the air blast resistance near lower side body 11 can be reduced, suppress the reduction of air quantity.
