Abstract
The present invention addresses the problem of providing an air conditioner that suppresses an increase in power consumption which accompanies the starting and stopping of a compressor, and that has high energy efficiency. In response to such problem, this air conditioning device is provided with a refrigeration cycle device formed by connecting an outdoor unit equipped with a compressor and a plurality of indoor units. On the basis of the temperature difference information of an intake air temperature and a set temperature, the indoor units perform an air conditioning operation by switching between a thermo-ON operation that performs a cooling operation or a heating operation and a thermo-OFF operation that stops the cooling operation or the heating operation. If an indoor unit (A) satisfies a thermo-OFF condition by which the thermo-ON operation is switched to the thermo-OFF operation and if there is no indoor unit in the thermo-ON operation other than the indoor unit (A), the air conditioning device shifts to a start/stop control operation mode that causes any of the indoor units to perform the thermo-ON operation.

Detailed description of the invention
Conditioner in the present invention possesses and is connected with multiple indoor set by the off-premises station with compressor and the refrigerating circulatory device formed, indoor set uses the temperature difference information of intake air temperature and design temperature, the thermocouple carrying out cooling operation or heat running open running and the thermocouple that stops cooling operation or heat running close operate between change and carry out in the conditioner of operation of air conditioner, meet indoor set A from thermocouple open running thermoelectric couple close running conversion condition, when the indoor set opened in running when not having thermocouple except indoor set A, the accidental stopping suppression operation mode conversion that running opened by thermocouple is carried out to making arbitrary indoor set.According to the present invention, meet indoor set A and open from thermocouple the thermocouple closedown condition that running thermoelectric couple closes running conversion, when the indoor set opened in running when not having thermocouple except indoor set A, by possess arbitrary indoor set is carried out accidental stopping that thermocouple opens running suppresses operation mode, can become and can reduce the accidental stopping time of compressor and suppress the air conditioner that the energy saving of the increase of the power consumption caused with the accidental stopping of compressor is high.
In conditioner of the present invention, use Fig. 1 ~ Figure 12, be below described in detail.
Embodiment 1
Use Fig. 1 ~ Fig. 8 that the first embodiment of the present invention is described.
Fig. 1 is the circulatory system figure of the structure representing the conditioner being arranged in present embodiment.Represent in the present embodiment relative to an off-premises station 90, the example connecting two indoor sets 91a, 91b.The present invention is not defined in this, and off-premises station 90, indoor set 91 connect number of units can be different.
Two indoor sets 91a, 91b are connected to off-premises station 90 side by side by liquid pipe 13 and tracheae 12.Off-premises station 90 possess in inside compressed refrigerant (not shown) compressor 1, carry out the heat exchange of outdoor air and the cold-producing medium supplied by outdoor fan 4 outdoor heat converter 3, for by the suction inlet of compressor 1 with the direction outdoor heat converter 3 in ejiction opening and the cross valve 5 other direction tracheae 12 changed and is connected.The other end of the outdoor heat converter 3 be connected with cross valve 5 is connected to liquid pipe 13 by outdoor expansion valve 8.
In indoor set 91, a side of indoor heat converter 16 is connected to tracheae 12, the opposing party is connected to liquid pipe 13 by indoor expansion valve 18.Supplied the air of space suction indoor by indoor fan 17 in indoor heat converter 16.The appointment of operation mode that user is started by the running that indoor set is carried out in remote control 92 and stopped, freezing and heat, the input etc. of design temperature.The regulating power of air-conditioning based on the detected temperatures (inlet temperature) of design temperature and inhaled air temperature sensor 21 temperature difference and determine.
As shown in Figure 2, when inputting the signal started running from remote control 92 to controller 60, operation of air conditioner starts, and the respective driver from controller 60 to off-premises station 90 and indoor set 91 transmits control signal.
About requiring that from remote control 92a the situation of cooling operation illustrates action.In this case, in FIG, by cross valve 2 to the loop conversion represented by solid line in figure, outdoor fan 4 and indoor fan 17a action is made with the revolution specified.
The cold-producing medium compressed by compressor 1 is condensed by carrying out heat exchange with outdoor air and liquefies in outdoor heat converter 3.To be reduced pressure in indoor expansion valve 18a to the liquid refrigerant that liquid pipe 13 flows out by the outdoor expansion valve 8 of full-gear and become low-temp low-pressure and in inflow indoor heat exchanger 16.The cold-producing medium evaporation of air heat absorption becomes overheated gas cold-producing medium and flows out to tracheae 12 indoor.The room air cooled by this effect is freezed to interior space supply to the interior space.The cold-producing medium of gasification to be back in compressor 1 by the cross valve 2 in off-premises station 90 by tracheae 12.Now, indoor expansion valve 18b is full-shut position, and indoor fan 17b is halted state.
Also having running commencing signal from remote control 92b, indoor expansion valve 18b is appropriateness adjustment aperture also, and the cold-producing medium in liquid pipe 13 reduces pressure and inflow indoor heat exchanger 16b, carries out heat exchange with the room air supplied by indoor fan 17b.The gas refrigerant of evaporation converges with the cold-producing medium evaporated at indoor set 92a, is back to off-premises station 90.
On the other hand, remote control 92a and remote control 92b is when heating requirement, by cross valve to the loop conversion represented by dotted line in Fig. 1, makes outdoor fan 4 and indoor fan 17 action with the revolution specified.The cold-producing medium compressed by compressor 1 is by tracheae 12 inflow indoor heat exchanger 16a, 16b.By to the room air heat release supplied by indoor fan 17 in indoor heat converter 16, refrigerant condenses is liquefied, on the other hand, to heating indoor space.After the liquid refrigerant condensed converges in liquid pipe 13, in outdoor expansion valve 8, decompression becomes low-temperature low-pressure refrigerant, and in outdoor heat converter 3, air obtains heat and evaporates outdoor.Then, return compressor 1 by cross valve 2, again repeat compression section.
Action during refrigeration about such air-conditioning is described in detail.The mode that the intake air temperature Tin1 that the revolution of compressor 1 detects with the suction thermistor 21 of each indoor set 91 is equal with the design temperature Ts with remote control setting controls., the air conditioning capacity when the lower limit ability running of the situation of the ability surplus relative to indoor load air-conditioning, indoor duty factor compressor 1 is little etc., the situation that the intake air temperature Tin of indoor set 91 is lower than design temperature can be there is.
Under these circumstances, close the indoor expansion valve 18 of indoor set 91, carry out stopping the thermocouple of refrigeration action to close running.Close in running at thermocouple, due to not to indoor heat converter 16 the supply system cryogen, therefore, the cooling effect produced by the evaporation of cold-producing medium there will not be.Therefore, can slowly be risen by the load room temperature of the interior space.Then, when inlet temperature uprises before reaching set point of temperature, again open indoor expansion valve 18, again open thermocouple and open running.
Fig. 3 be medelling represent such existing control in the figure of action.Horizontal axis representing time, the longitudinal axis represents the room temperature (i.e. intake air temperature Tin) of indoor set 91a and 91b, running opened by thermocouple and thermocouple cuts out the state of running, and represents the operating condition of compressor.
It is that thermocouple cuts out running that indoor set 91 reaches when lower limit LL opened by thermocouple at intake air temperature Tin, is then that running opened by thermocouple when temperature reaches thermocouple closedown higher limit HL.At this, represent relative to the situation that design temperature is+2 DEG C, LL is-1 DEG C, temperature width is 3 DEG C about HL1.Further, open about the width of HL and the LL relative to design temperature, thermocouple or thermocouple is cut out time condition, the present embodiment is 1 example, and not only intake air temperature Tin, also can add the conditions such as time.
In figure 3, in sart point in time, indoor set 91 two all operates, owing to reaching lower limit LL1 at the intake air temperature Tin1 of moment t1 indoor set 91a, so indoor set 91a is that thermocouple cuts out running.Then, indoor set 91b mono-remains in operation, and when the moment, t2 reached lower limit LL2, indoor set 91b is also for thermocouple cuts out running.
At this moment, because indoor set 91a, 91b are simultaneously for thermocouple cuts out running, therefore compressor 1 is also halted state.So, multiple indoor set 91a, 91b be thermocouple close running time, sporadic ground was consistent time, need to stop compressor 1.When compressor 1 is halted state, owing to can produce the loss of the energy that high temperature refrigerant to mix with low-temperature refrigerant etc., therefore, compared to non-stop running, the electric power of consumption can increase.
In addition, compressor 1, once be halted state, because needs compressor 1 inlet pressure is even, in general can not start for about three minutes again.Therefore, exceed thermocouple in the room temperature of moment t3 indoor set 91a and close higher limit HL1, thermocouple can not be carried out open before the moment t4 that can start compressor 1.
So, in existing control, during compressor 1 stops, also there is the possibility that room temperature rises, also can have problems in comfortableness.
Therefore, in the present embodiment, when satisfied all indoor sets are the condition of thermocouple closedown running, arrange and temporarily change the mechanism that indoor set is the condition that thermocouple cuts out.Represent action case in this case in the diagram, represent the flow chart of this control in Figure 5.
In moment t1, indoor set 91a is that after thermocouple cuts out running, indoor set 91b is identical with existing control by an aspect remained in operation.Then, the intake air temperature Tin2 (i.e. room temperature) that the suction thermistor 21 of indoor set 91b detects reaches the moment that lower limit LL2 opened by thermocouple, implements the control of the present embodiment.That is, in controller 60, when detecting that indoor set 91b stops, when all indoor set 91a, 91b are thermocouple closedown running, do not make indoor set 91b be that thermocouple cuts out running, be converted to accidental stopping and suppress operation mode.Further, thermocouple is opened lower limit LL2 and reduce set point of temperature (such as 1 DEG C), open the mode of running to indoor set 91b transmission instruction to continue thermocouple.Thereby, it is possible to avoiding indoor set 91b is at once the state that thermocouple cuts out, other indoor sets (in the present embodiment 91a) can wait until that thermocouple is opened.Therefore, due to the accidental stopping of compressor 1 can be suppressed, the increase of compression power can be avoided, improve energy saving.
Further, when indoor set 91a be thermocouple open when, complete accidental stopping suppress operation mode, make thermocouple open lower limit LL2 and be back to common value.Thus, indoor set 91b thermoelectric couple closes running transfer.
So, open lower limit LL due to thermocouple and be back to original value after this control completes, so, after this control completes, continue the running within the scope of typical temperature.Therefore, room temperature lowly can be defined in temporarily, and room temperature continues low inferior being not in good state and can not occur, and can keep comfortableness.
, during accidental stopping suppresses operation mode, the intake air temperature Tin2 temporarily indoor set 91b reduces.Therefore, in the present embodiment, continue the running of indoor set 91b on the one hand, on the other hand, making at the thermocouple indoor set 91a closed in running is that the thermocouple closedown higher limit HL2 that thermocouple is opened reduces regulation amplitude (such as 1 DEG C).Therefore, even if under the state little with the temperature difference of setting, also thermoelectric couple running transfer can be opened.
Thus, in moment t3, the intake air temperature Tin1 of indoor set 91a can not reach the temperature that usual thermoelectric couple opens running transfer, can shift to an earlier date thermoelectric couple and open running transfer.Due to the indoor set 91a just operated in thermocouple closedown can be made to be that running opened by thermocouple, therefore in the complete cost control of this moment, operation mode is suppressed to be back to common operation mode from accidental stopping.That is, the control of lower limit LL2 opened by releasing reduction thermocouple closedown higher limit HL1 and thermocouple, is back to usual state.Therefore, indoor set 91b is that thermocouple cuts out running.As far as possible little suppression so, the reduction amplitude of the intake air temperature Tin2 of indoor set 91b can be suppressed by this control, so on the impact of comfortableness, and can reduce aircondition consumption electric power.
As above-mentioned, this control due to be judged as all indoor sets 91 for thermocouple close running time carry out action, so, reliably can avoid the stopping of compressor 1 where necessary.Therefore, it is possible to do not depend on multiple indoor set repeatedly thermocouple open the ground such as periodicity that thermocouple cuts out and to be always inhibited the effect of accidental stopping.
Further, in the present embodiment, be the moment that thermocouple is opened complete accidental stopping suppression operation mode at indoor set 91a, but the variation in order to circulate at switch instant freezing-inhibiting, the duration of runs of indoor set 91a and 91b only can be repeated in official hour.
In addition, the duration of runs opened by the thermocouple in the present embodiment in order to extend indoor set 91b, changes the temperature of critical value, but the method that the duration of runs opened by the thermocouple for extending indoor set 91b also can be additive method.Specifically, can being after reaching threshold temperature, extending the method for being judged as the time that thermocouple cuts out.In addition, also can be that machine forcibly adjusts the aperture etc. of indoor expansion valve 18 outdoor, carries out the method opening identical air-conditioning action with thermocouple when being judged as that indoor set is thermocouple closedown.
In addition, illustrate when the thermocouple meeting indoor set 91b cuts out condition in the present embodiment, enter the accidental example stopping suppressing operation mode, but such as when connecting multiple indoor set, the running that whether can continue to be produced by accidental stopping suppression operation mode can be set to each indoor set in advance.Therefore, when the running produced when being set as can carrying out suppressing operation mode by accidental stopping, action is carried out as the present embodiment, but running opened by the thermocouple that also can such as produce when being set as indoor set 91b cannot continuing to suppress operation mode by accidental stopping, stopping identically with Fig. 3.In this case, when the condition that satisfied all indoor sets 91 are closed for thermocouple, because the indoor set by finally remaining in operation can produce the situation that compressor 1 stops, situation about remaining in operation, therefore also can produce the condition that the consumption electric power with the accidental stopping of compressor 1 can not be avoided to increase, the function of the comfortableness of the facilities isopreference customer-side of corresponding indoor set 91 can be possessed.
Represent action when heating running in figure 6.Also identical with during refrigeration when heating, indoor set 91a is that thermocouple cuts out running at the moment t1 reaching thermocouple and open ceiling temperature HL1.Then, the intake air temperature Tin2 of indoor set 91b continues to rise, reach thermocouple at moment t2 and open ceiling temperature HL2, but due to as indoor set 91b be thermocouple close time all indoor sets 91 to close for thermocouple and operate, therefore set with set point of temperature the thermocouple that thermocouple opens indoor set 91b higher and open ceiling temperature.Thus, indoor set 91b can continue thermocouple and opens running.And the thermocouple of cutting out indoor set 91b owing to setting thermocouple higher with setting cuts out lower limit, so, indoor set 91a can be made in advance to be that thermocouple is opened, indoor set 91b thermocouple can be made as a result to close.Therefore, it is possible to suppress the rising being arranged in the intake air temperature Tin2 of indoor set 91b.
So, the increase of the consumption electric power that comfortableness also can be kept when heating running to a certain extent can also to cause by avoiding the accidental stopping of compressor 1, can provide the aircondition that energy saving is high.
Fig. 7 represents the action case under air conditioner load different situations.At moment t2 because satisfied all indoor sets 91 are thermocouple closedown condition, even if in the present embodiment, accidental stopping suppression operation mode also can be entered.Further, lower limit temperature LL2 opened by the thermocouple reducing the indoor set 91b that thermocouple is opened on the one hand, and the thermocouple reducing indoor set 91a on the other hand cuts out ceiling temperature HL1.
When remaining in operation with this understanding, the intake air temperature Tin2 due to indoor set 91b continues to reduce, and is therefore when needing the time before thermocouple is opened at indoor set 91a, and the problem of comfortableness aspect becomes large.In addition, with the reduction of the intake air temperature Tin2 of indoor set 91b, the evaporating temperature of freeze cycle also decreases, and the efficiency of freeze cycle also reduces, and consumption electric power increases.Therefore, there is the effect of the consumption electric power suppression that can not fully obtain producing by suppressing the accidental stopping of compressor 1.
Therefore, in the present embodiment, reach in the value of the intake air temperature Tin2 of indoor set 91b moment that revised thermocouple opens lower limit LL2 to complete accidental stopping and suppressing operation mode.Therefore, the running not needing to continue inefficiency can not only be avoided, the reduction of comfortableness can also be prevented.
Fig. 8 be relative to identical problem do not arrange the intake air temperature Tin2 of indoor set 91b lower limit and continuing the accidental example stopping suppressing to arrange restriction in the operation mode time.Stop to accidental the time point timing suppressing operation mode conversion at moment t2, when through predetermined binding hours △ T moment t3 indoor set 91a can not thermocouple open, the load of indoor set 91a is little, afterwards, the running continuing indoor set 91b is judged as that energy-saving effect is low, removes this control, and the thermocouple making the thermocouple of indoor set 91a cut out higher limit HL1 and indoor set 91b opens lower limit LL2 and recovers initial value, indoor set 91b thermocouple cuts out, stops compressor 1.
Therefore, due to the running of the compressor 1 under the inefficient state of freeze cycle can be limited, so, the increase of unnecessary consumption electric power can be avoided.This control is effective especially to the situation that the thermocouple shut-in time is long.
Embodiment 2
Secondly, be described about carrying out the accidental control action started when judging suppressing operation mode that stops.Fig. 9 is the flow chart of this control.
In flow chart in fig .9, added before the accidental stopping of beginning suppresses operation mode relative to embodiment 1 and judge whether to there is the determining step that the indoor set of holding state opened by thermocouple.The state (situation that situation about heating bends down) that holding state represents that intake air temperature Tin is higher than predetermined set point of temperature opened by so-called thermocouple, judge the presence or absence of the indoor set that easy thermocouple is opened, judge the accidental beginning stopping suppressing operation mode based on this point.
Use Figure 10, the action case of this control is described.Even if also meeting at moment t1 indoor set 91a is in the present embodiment the condition that thermocouple cuts out the thermocouple cut out that operates, is also at moment t2 indoor set 91b.Such as, under such circumstances, in the action case shown in Fig. 7 of embodiment 1, in binding hours, indoor set 91b is maintained thermocouple and opens running, but in the present embodiment, confirm the state of the indoor set 91a that thermocouple cuts out, judge that accidental stopping suppresses operation mode whether to start.
In embodiment 1, represent and the lower limit of binding hours and room temperature be set, by accidental stop suppressing operation mode and the increase of the consumption electric power that produces, for the reduction of comfortableness being maintained the action case in Min..In the present embodiment, infer whether indoor set 91a is converted to thermocouple at the appointed time and open running, when be judged as indoor set 91a transfer in advance thermocouple open running, be converted to accidental stopping suppress operation mode, indoor set 91b is maintained thermocouple and opens running.On the other hand, when judge indoor set 91a transfer to need the time before running opened by thermocouple, be not converted to accidental stopping and indoor set 91b be converted to thermocouple with suppressing operation mode and close running.
In order to judge whether thermocouple closedown indoor set 91a becomes thermocouple in advance and open running, uses the intake air temperature Tin1 of indoor set 91a to judge in the present embodiment.That is, define that to open lower limit LL1 than thermocouple high and close the judgement temperature TC1 of below higher limit HL1 for thermocouple, temperature TC1 judges whether thermocouple closedown indoor set becomes thermocouple in advance and open running to use this to judge.More particularly, when the intake air temperature Tin1 that thermocouple cuts out indoor set 91a is larger than TC1, be judged as carrying out in advance the thermocouple holding state that possibility that thermocouple opens is high, the indoor set only opening holding state at thermocouple is deposited the thermocouple continuing indoor set 91b in case and is opened running.
In the present embodiment, the intake air temperature Tin1 that thermocouple cuts out indoor set 91a is lower than judging temperature TC1 at moment t2, and the indoor set opening holding state due to thermocouple does not exist, so, stop indoor set 91b at moment t2.Therefore, with usually controls identical stop compressor 1 after, reach at the intake air temperature Tin2 of indoor set 91b the moment t3 that thermocouple cuts out ceiling temperature HL2, again startup compressor 1.So, when being converted to accidental stopping and suppressing operation mode, reduces at the intake air temperature Tin2 of indoor set 91b, under the efficiency of freeze cycle reduces such condition, temporary transient enthusiasm compressor 1 stopped, avoiding these problems.Namely, when using the situation of the accidental stopping of accidental stopping suppression operation mode suppression compressor, not using accidental stopping to suppress operation mode temporarily to be stopped by compressor, owing to can select to be assumed to be the few method of operation of consumption electric power, therefore finally the conditioner that energy saving is high can be provided.
Further, in the present embodiment, the accidental judgement stopping suppressing operation mode to start is carried out when the indoor set being judged as carrying out thermocouple and opening running is 0.Such as, when starting when only having an indoor set running, the intake air temperature of this indoor set is also high, due to the needs time before meeting thermocouple closedown condition, therefore at the time point meeting thermocouple closedown condition, predict the difficulties such as the intake air temperature of other indoor sets, can not such judgement be carried out.In the present invention, when the indoor set being judged as carrying out thermocouple and opening running is 0, the information of other indoor sets now can be used, judge the accidental beginning stopping suppressing operation mode.
And, in the present embodiment, in order to judge the accidental beginning stopping suppressing operation mode, judge based on the indoor set that whether there is thermocouple and open holding state, but the present invention is not limited thereto, such as, the thermocouple shut-in time etc. in the transformation period of the intake air temperature of indoor set, running in the past can be used to judge.In the present invention, during owing to being judged as thermocouple to open indoor set be 0, be judged as the accidental beginning stopping suppressing operation mode, therefore use the information of other indoor sets of its time point also can judge.Embodiment 3
Represent the embodiment under thermocouple being opened lower limit is set as two stage situation in fig. 11.When lower limit LL opened by reduction thermocouple, because temporarily room temperature reduces, in order to prevent this situation, in the present embodiment, the second thermocouple being opened lower limit mL and being set as opening the high temperature of lower limit LL than common thermocouple.Usually, the time point thermocouple that temperature reduces before reaching mL cuts out, and only when entering accidental stopping and suppressing operation mode, reduces the critical value that thermocouple cuts out before reaching LL.
Figure 11 is used to be described about action case.In moment t1, because the inlet temperature Tin1 of indoor set 91a reaches mL1, indoor set 91a is therefore made to become the state of thermocouple closedown.Then, the inlet temperature Tin2 of indoor set 91b continues to decline, and owing to reaching mL2 at moment t2, therefore indoor set 91b meets the condition that thermocouple cuts out., now, when making indoor set 91b be thermocouple closedown, the indoor set that thermocouple is opened is not had, due to must compressor be stopped, so, be converted to accidental stopping and suppress operation mode.Thus, the thermocouple of indoor set 91b is opened lower limit and changes to LL2 from mL2, continue the cooling operation of indoor set 91b.Then, when opening with temperature rising indoor set 91a thermocouple, complete accidental stopping and suppressing operation mode, indoor set 91b thermoelectric couple closed condition is changed.
Now, the inlet temperature of indoor set 91b is lower than mL2, but, would not reduce to LL2.Therefore, it is possible to can not temperature reduction be blown out by indoor set 91b and suppress the increase of the consumption electric power of the stop and start with compressor to user with bring discomfort.
Embodiment 4
Figure 12 is the figure of the action case represented when accidental stopping suppresses the indoor set opened by thermocouple during operation mode to be fixed.In the present embodiment, the situation that three indoor sets connect side by side is represented as an example.In the present embodiment, in order to prevent all indoor set thermocouples from closing, when all indoor set thermocouples cut out, preset in the mode that indoor set 91c thermocouple is opened.
In the present embodiment, due to moment t1 indoor set 91a inlet temperature Tin1, reach thermocouple respectively at the inlet temperature Tin2 of moment t2 indoor set 91b and open lower limit LL, therefore meet the condition that thermocouple cuts out.Because indoor set 91c is the state that thermocouple cuts out, so when moment t2 indoor set 91b thermocouple cuts out, all indoor sets are the state that thermocouple cuts out, and compressor stops.Therefore, in the present embodiment, by making accidental stopping suppress operation mode action, by the State Transferring that indoor set 91c thermoelectric couple is opened, compressor 1 is avoided to stop.Further, indoor set 91c is back to thermocouple closed condition by the moment t3 being the state that thermocouple is opened at indoor set 91a.Also indoor set 91c can be maintained thermocouple open mode, because the duration of runs in this case under the state that the inlet temperature of indoor set 91c is low is long, the therefore mode of the even state of closing of preferred thermoelectric.And, under accidental stopping suppression operation mode takes place frequently such condition, because the inlet temperature that there is indoor set 91c continues low possibility, therefore easy by returning the state that thermocouple cuts out, avoid such condition.
So, suppressing in operation mode in accidental stopping, by being fixed as the indoor set of thermocouple open mode, can prevent inlet temperature in indoor set 91a and 91b from reducing.Therefore, when be arranged at want to avoid indoor set 91a and 91b inlet temperature low place (cubicle etc.), room temperature in such indoor set can be avoided low or too high.In addition, changing the little indoor set etc. of the impact that brings to user by selecting to be arranged at each the inlet temperature such as indoor set in large space, suppressing the discomfort brought to user, and the consumption electric power with the accidental stopping of compressor can be suppressed to increase.
