Abstract
A method and apparatus for controlling discharged air flow of air conditioner, includes: the step of identifying the running state of a compressor, for identifying whether the compressor is in a ruunning state or a stopping state, and working frequency; the step of controlling blowing air flow, for controlling the height of up/down wind direction of blowing-in cooling gas and the speed of left/right wind direction of blowing-in cooling gas based on the running state of the compressor. According to the inventive method, the up/down and left/right wind direction and wind speed are controlled, by considering the running state of the compressor and the blowing time of discharged air flow, in order to minimize the temperature in room, accordingly a pleasant indoor condition is produced.
Description
The present invention relates generally to air-conditioning, be specifically related to a kind of method and device thereof that is used to control cold air flow from air conditioner, its can under the duty of considering compressor and the situation of cold wind air flow blowing time on/down and a left side/right wind direction and air quantity control, so that the indoor temperature difference reaches minimum, can create comfortable more pleasant indoor environment thus.
Usually, as shown in Figure 1, the kind of refrigeration cycle of air-conditioning comprises: be used for cold-producing medium is compressed to obtain the compressor 11 of high-temperature high-pressure refrigerant; Be used to make the condenser 12 of the gaseous refrigerant liquefaction of the HTHP that compressor 11 provides; The capillary 13 that the liquid refrigerant pressure that being used to make is provided by condenser 12 descends and its part is evaporated; And be used to make cold-producing medium evaporation the evaporimeter 14 that is provided by capillary 13 so that air is cooled off.
Next will the operation of kind of refrigeration cycle with said structure be described.
Be sent to by 11 refrigerant compressed of compressor and carry out condensation in the condenser 12.Make the cold-producing medium of gaseous state become liquid state by condenser 12, be discharged into consequent heat outdoor simultaneously.Pressure descends the cold-producing medium that comes out from condenser 12 by the effect of capillary 13 again.Because pressure descends, a part of liquid refrigerant will gasify, so the state of the cold-producing medium that flows in the capillary 13 is in gas-liquid mixed two phases.The cold-producing medium of low pressure absorbs heat by evaporimeter 14 and becomes steam and enter next kind of refrigeration cycle, thereby reaches the purpose of refrigeration.
That is,,, also be cooled thereby make through its surperficial air so the surface of evaporimeter 14 will be cooled because cold-producing medium becomes gaseous state from liquid state and need absorb a large amount of evaporation latent heats.Therefore, indoor hot-air undertaken being cooled after the heat exchange by indoor fan 15 and evaporimeter 14 and be blown into once more indoor, thereby indoor temperature is descended.The outdoor fan 16 that is installed in condenser 12 1 sides is to condenser 12 blowings, is used for to the air conditioning appliance outside drain because the hot-air that cold-producing medium liquefaction is produced, and provides new air to carry out rapid condensation.
The air-conditioning that utilizes above-mentioned kind of refrigeration cycle the room to carry out refrigeration comprises, by the integrated air container that single device constituted with above-mentioned refrigerant cycles, with and compressor and condenser is installed on outdoor and evaporimeter is installed on two types of indoor split-type air conditioners.Usually the refrigerating capacity of split-type air conditioner is stronger, and the branch that wherein is used to install compressor and condenser is known as outdoor unit, and the branch that is used to install evaporimeter is known as indoor unit.
Figure 2 shows that the simplified schematic diagram of split-type air conditioner indoor unit internal structure, it comprises: be positioned at the air draught barrier (grill) 21 that cabinet 20 belows are used to suck room air; Be installed on cabinet 20 tops and be blown into the blowing barrier 22 of cooling air by it; Be installed on cabinet inside and be used for evaporimeter 23 that the room air that flows into is cooled off; Be installed on evaporimeter 23 front surfaces, be used to measure the temperature sensor 24 of temperature of the room air of inflow; Be installed on cabinet inside, be used to make room air to flow into and be blown into the indoor fan 25 of cooling air.Also be equipped with at blowing barrier 22 places in addition be used for to cold wind be blown into that direction controls/leeward is to wind deflector 26 and a left side/right wind direction wind deflector 27.
For the indoor unit with said structure, when drive chamber's internal fan 25, the room air that flows through air draught barrier 21 will be cooled by evaporimeter 23, be blown into indoorly subsequently again by blowing barrier 22, and the temperature in room is descended.
Wherein, air-conditioning with said structure all is useful on the function of setting indoor temperature; therefore; when being set by the user required temperature as shown in Figure 3; can come temperature in the measuring chamber by the indoor temperature transmitter that is installed in the air-conditioning entrance side, when measured indoor temperature is lower than the floor value Td that sets temperature, compressor will be shut down; and when measured indoor temperature is higher than the last dividing value Tu of design temperature, the then compressor running of will starting shooting.
Because compressor repeats the ground start and shuts down, so indoor temperature will be on design temperature raises repeatedly in the scope between dividing value Tu and the floor value Td and descends, to make room maintenance refrigeration condition thus.
As shown in Figure 2, be used to control the cold wind direction a left side/right wind direction wind deflector 27 and/leeward is installed in the side of air-conditioning blowing barrier 22 to wind deflector 26.On/leeward to wind deflector 26 control cold wind blowing air flow in vertical direction to a, left side/right wind direction wind deflector 27 then control cold wind blowing air flow in the horizontal direction to.
When by last/leeward to wind deflector 26 and a left side/right wind direction wind deflector 27 to indoor when being blown into its temperature and being lower than the air of indoor temperature, will be inevitably in the room with on occurring/the following temperature difference and a left side/right temperature difference.

Wherein, on/following temperature approach refers to the difference between the temperature that records from distance room ground 0.1m and 1.1m place, its represented in the room various on/maximum temperature difference value in the following temperature difference.
And a left side/right temperature approach refers to by relatively apart from the maximum temperature values in the Temperature Distribution on the horizontal imaginary plane of room floor constant altitude and the measured temperature difference of minimum temperature value.
As mentioned above, automatic backswing function for prior art, since last/leeward to wind deflector and a left side/right wind direction wind deflector no matter compressor duty how all with constant reciprocating speed to the indoor cold wind that is blown into, make/decrease of the following temperature difference and a left side/right temperature difference is very limited, so understand and in the room, producing uncomfortable feeling owing to the temperature difference makes the people.

As shown in Figure 7, the method that the cold wind air-flow of air-conditioning is controlled is comprised according to of the present invention being used for: suitable air-flow is provided with step S1, be used to coordination function (harmony function) is set so that the cold wind air-flow can be after the air-conditioning entry into service duty or the air-flow control time according to compressor change; Compressor operating state recognition step S2 is used to discern the in running order still stopped status of compressor, and operating frequency; Blowing-out gas current control step S3, be used for according to the duty of compressor in a different manner to be blown into cold wind/height of following wind direction, and the speed of a left side/right wind direction is controlled; Air-flow control time determining step S4 is used for judging the blowing control time; And air-flow time treatment step S5, be used for according to the air-flow control time to be blown into cold wind/height of following wind direction, and the speed of a left side/right wind direction is controlled.
Be provided with among the step S1 at suitable air-flow; during coordination function button on supressing the functional unit that is installed in air-conditioning; it will judge the in running order still stopped status of compressor; according to duty on the cold wind/following wind direction and a left side/right wind direction control; meanwhile; detect the time when pressing the coordination function button, and after having passed through predetermined amount of time on/following wind direction and a left side/right wind direction and air quantity control.
As shown in Figure 8 after air-conditioning brings into operation; when it is in normal operating conditions; compressor based on set temperature between dividing value and the floor value alternately off and on start with shut down; go up during this period/leeward keeps its level to wind deflector, and a left side/right wind direction wind deflector then remains on inactive state.In addition, remain on the constant big or small level by the determined air quantity of the rotating speed of indoor fan.
Under this state,, then will in turn carry out following step, i.e. compressor operating state recognition step S2 and blowing-out gas current control step S3 continuously when being provided with at suitable air-flow when being provided with coordination function among the step S1.
When compressor is in running order in compressor operating state recognition step S2, then by on shown in Figure 2/leeward will be set to the direction up that is higher than reference direction (horizontal direction (α °)) shown in Fig. 9 a (α °+a °) to the height of on motion determined of wind deflector 26/following wind direction, in blowing-out gas current control step S3, will control simultaneously a left side/right wind direction automatic reciprocating speed so that speed Wr faster than reference reciprocating speed Wc, shown in Fig. 9 b.
Refer to a left side/right side reciprocating speed of a backswing operation common left side of adopting/right wind direction wind deflector automatically with reference to reciprocating speed Wc.
The state lower edge of compressor operating upward to on/reason that following wind direction is controlled is in order to suppress the temperature difference.That is, very big owing to the temperature that is blown into indoor air-flow by indoor heat converter is generally very low with the indoor temperature difference, so it is the principal element that has the big temperature difference in the person of the residence zone of action that causes from the floor to the 1.1m altitude range.
And the automatic reciprocating speed of a control left side/right wind direction to make reason of its speed of operating faster than the automatic backswing in an existing left side/right side be for the cold wind that is blown into can be mixed quickly with indoor air-flow.
Therefore, when compressor moves, along upward to last/following wind direction is controlled, simultaneously along a left side/right wind direction carries out faster back and forth operation, can make in the interior space on/the following temperature difference and a left side/right temperature difference can reduce significantly.
On the other hand; when compressor is in stopped status in compressor operating state recognition step S2; on/leeward will be set to the downward direction that is lower than reference direction (α °) shown in Fig. 9 a (α °-b °) to the height of wind deflector; control the automatic reciprocating speed of a left side/right wind direction simultaneously, so that speed Ws is lower than with reference to reciprocating speed Wc.
When compressor is in stopped status along downward direction on/reason that following wind direction is controlled be because; it is little to compare difference through the temperature that is blown into indoor air-flow after the indoor heat converter and indoor temperature, therefore can not cause any temperature difference in the person of the residence zone of action from the floor to height 1.1m scope.
And the automatic reciprocating speed of a control left side/right wind direction makes its reason that is slower than the speed that has the automatic backswing operation in a left side/right side now be, in order under the situation that reaches minimum in the sense of discomfort that the people is produced owing to cold wind flows the air-flow in the person of the residence zone of action to be mixed.
Therefore; as mentioned above, in the stopped status of compressor, last/following wind direction is controlled along downward direction; and reduce the automatic reciprocating speed of a left side/right wind direction simultaneously, thereby make indoor on/the following temperature difference and a left side/right temperature difference significantly reduce and keep cooling effect constantly.
Therefore, as shown in Figure 8, when coordination function was started working, compressor will be according to the temperature that sets start or shutdown repeatedly between last dividing value and floor value.When compressor is in running order; on/with points upwards, and a left side/right wind direction wind deflector moves rapidly and is blown into cold wind leeward to wind deflector, and when compressor is in stopped status; on/with directed downwards, a left side/right wind direction wind deflector moves and is blown into cold wind leeward lentamente simultaneously to wind deflector.In addition, indoor fan will keep constant rotating speed, and air quantity correspondingly is maintained on the constant big or small level.
Simultaneously, in compressor operating state recognition step S2, if when the operating rate of compressor accelerates, when its operating frequency surpasses predetermined level, then in blowing-out gas current control step S3, on/leeward to the wind deflector height will be set to be higher than reference direction upward to, and the automatic reciprocating speed of a left side/right wind direction will be faster than its reference velocity.
Similarly, when the operating frequency of compressor is higher, colder wind relatively will be blown into, flow controlling method of air when simultaneously in running order with compressor is identical, increase the automatic reciprocating speed of a left side/right wind direction, so that cold wind can mix with the room air in room, and cold wind directly can be blown in the person's of residence the zone of action.
On the contrary, when the operating rate of compressor in compressor operating state recognition step S2 slack-off, when its operating frequency is lower than predeterminated level, then in blowing-out gas current control step S3 on/leeward is set to be lower than the downward direction of reference direction to the height of wind deflector, the automatic reciprocating speed of a left side/right wind direction will become and be lower than reference velocity simultaneously.
Similarly, when the operating frequency of compressor is hanged down, the cold wind that is blown into is less relatively, flow controlling method of air used when simultaneously in running order with compressor is identical, because the temperature difference of its temperature and room indoor temperature is less, cold air will directly be blown in the person's of residence the zone of action, and because the reciprocating speed of a left side/right wind direction is lower, can make since cold wind mobile the sense of discomfort that may cause drop to minimum degree.
For said method, it preferably is independent of the coordination function operation flow controlling method of air of the duty and the stopped status of compressor (promptly according to) and carries out operating frequency according to compressor separately to being blown into the method that air-flow is controlled.
Certainly; use flow controlling method of air simultaneously at needs according to the duty and the stopped status of compressor; and in the situation according to the flow controlling method of air of the operating frequency of compressor; under the state that compressor is moving, should consider the operating frequency state of compressor and the sensing result of indoor temperature transmitter simultaneously.
Promptly; because the flow controlling method of air according to the operating frequency of compressor is to carry out in the process of compressor operating rather than in the stopped status; so with identical according to the flow controlling method of air of compressor operating state; it will be controlled/following wind direction points upwards, and the reciprocating speed of a control left side/right wind direction wind deflector quickens simultaneously.
Simultaneously; when the operating frequency of compressor relatively low; and the temperature difference of indoor heat converter; promptly dry the temperature difference between air-flow and the room air; when being lower than predetermined level; identical when being in stopped status with compressor, preferably control/following wind direction directed downwards, and the reciprocating speed of a control left side/right wind direction makes it become relatively slow simultaneously.
In addition, in air-flow control time determining step S4 and air-flow time treatment step S5, under the situation of having enabled coordination function, will detect the required time length that the blowing-out gas stream of air-conditioning is controlled according to the duty of compressor, thus its air-flow is controlled suitably, thereby also can not felt too cold when making the person of residence in placing oneself in the midst of cold wind stream for a long time.
Specifically, for example, as Fig. 8, shown in 9a and the 9b, when cold wind in air-flow control time determining step S4 is blown into the time when having surpassed preset time length, in air-flow time treatment step S5, on/leeward to the height of wind deflector will be set to be higher than reference direction α ° upward to (α °+b °), and will control the reciprocating speed of a left side/right wind direction wind deflector, and its speed Ws is lower than with reference to reciprocating speed Wc, air quantity is lower than with reference to air quantity simultaneously.
Promptly; in air-flow control time determining step S4; cold wind is blown into feels faint as much as possible for human body being felt have; the in running order still stopped status of compressor no matter then; all will control/leeward is to the height of wind deflector; make it become up direction from horizontal direction, no matter how the duty of compressor all makes the automatic reciprocating speed of constant cycle of a left side/right wind direction wind deflector slack-off simultaneously.In addition, the air quantity that rotating speed determined by indoor fan will be reduced to lower level.
Therefore, it can be eliminated because the people places oneself in the midst of issuable sense of discomfort in the cold wind for a long time.
It preferably can carry out the control method according to the air-flow control time simultaneously, and according to the flow controlling method of air of the duty of compressor.Yet, depend on the different condition of embodiment, can be after air-conditioning be started working preset time, be independent of according to the flow controlling method of air of the duty of compressor and carry out control method according to the air-flow control time.
After air-conditioning is started working in the control method of the independent blowing air-flow of carrying out, the length of the duration that is blown into cold wind in the room will be judged, and after having passed through the scheduled time, last/leeward to the height of wind deflector be set to be higher than reference direction upward to, and the reciprocating speed of a control left side/right wind direction wind deflector makes it be lower than reference velocity, simultaneously air quantity is controlled, so that it is lower than reference levels.
Figure 10 shows that the block diagram that is used for device that the cold wind air-flow of air-conditioning is controlled according to of the present invention, it comprises: the indoor temperature transmitter 51 that is used to measure indoor air temperature; Be used to detect the in running order still stopped status of compressor, and the compressor operating state detector 52 of operating rate; The air-flow control time detecting unit 53 that is used for time detecting air-flow control time of starting working according to the time or the coordination function of air-conditioning entry into service; Be used for when the signal that receives from sensing cell, according to the gentle current control of the duty time output control signal of compressor with on changing/down and the MICOM 60 of a left side/right wind direction and air quantity; Be used under the control of MICOM 60 direction that control up or down is blown into air-flow, with on the blowing air-flow that changes air-conditioning/following wind direction driver element 62 and last/leeward be to wind deflector 26; Be used to control a left side/right wind direction driver element 63 and a left side/right wind direction wind deflector 27 of the direction of blowing air-flow; Be used to change rotating speed with to being blown into indoor fan driver element 61 and the indoor fan 25 that air quantity is controlled; And be used for the driven compressor unit 64 under the control of MICOM 60, the operating frequency of compressor 30 controlled.
