It should be noted that above-mentioned term " first ", " second " are only used for describing purpose, and it is not intended that instruction or dark Show relative importance or the implicit quantity for indicating indicated technical characteristic.Thus, " first ", the feature of " second " are defined It can express or implicitly include one or more this feature.
Because purification assembly 150 is in purification pattern and non-purification pattern, the windage that indoor set blower fan 170 produces air-flow is bright Aobvious difference, after purification function is opened, air-flow necessarily causes the heat transfer effect by indoor set heat exchanger 160 to decline by filtering Subtract, high load capacity problem easily occur, can accordingly be controlled according to the operational mode of air conditioner, air conditioner is subtracted in purification Less to the normal refrigeration of air conditioner or the influence of heat-production functions.
Such as after purification function is opened, the target tube temperature of the pipe temperature of indoor set heat exchanger 160 can be set, and detect in real time The pipe temperature of indoor set heat exchanger 160, feedback control is carried out to the refrigeration system of air conditioner according to the temperature difference of detection pipe temperature and target tube temperature System.
A kind of specific control mode is：
In air conditioner refrigerating operaton, if Tube Sheet of Heat Exchanger temperature is no more than the first temperature difference threshold less than target tube temperature after cleaning When being worth (such as 3 degree), feedback control can be carried out to indoor set blower fan 170 according to difference, Tube Sheet of Heat Exchanger temperature temperature is lower, indoor The rotating speed of machine blower fan 170 is faster.If the lifting of the rotating speed of indoor set blower fan 170 cannot be guaranteed Tube Sheet of Heat Exchanger temperature and maintain and target tube For the temperature difference when within the first temperature difference threshold, then the aperture of the throttling arrangement of kind of refrigeration cycle is compressed in increase, if still cannot be guaranteed Tube Sheet of Heat Exchanger temperature is maintained with the target tube temperature temperature difference when within the second temperature difference threshold, then carries out frequency reducing to compressor, so as to anti- Only the temperature of indoor set heat exchanger 160 is too low and high load capacity occur.
When air conditioner carries out refrigerating operaton, if Tube Sheet of Heat Exchanger temperature is no more than the first temperature higher than target tube temperature after cleaning During poor threshold value (such as 3 degree), feedback control can be carried out to indoor set blower fan 170 according to difference, Tube Sheet of Heat Exchanger temperature temperature is higher, The rotating speed of indoor set blower fan 170 is faster.If the lifting of the rotating speed of indoor set blower fan 170 cannot be guaranteed Tube Sheet of Heat Exchanger temperature and maintain and mesh The pipe temperature temperature difference is marked when within the first temperature difference threshold, then the aperture of the throttling arrangement of increase compression kind of refrigeration cycle, if still can not Ensure that Tube Sheet of Heat Exchanger temperature is maintained with the target tube temperature temperature difference when within the second temperature difference threshold, then frequency reducing is carried out to compressor, from And prevent the temperature of indoor set heat exchanger 160 too high and high load capacity occur.
Above-mentioned first temperature difference threshold and the second temperature difference threshold can be according to the specifications and requirement of indoor set heat exchanger 160 Configured, such as the first temperature difference threshold is set positive and negative 3 degrees Celsius, the second temperature difference threshold is arranged to positive and negative 5 degrees Celsius.
In addition, when purification assembly 150 is driven by drive device 140 and changed between purification pattern and non-purification pattern, Purification assembly 150 and the vertical range relative close on the surface of indoor set heat exchanger 160.Thus, when purification assembly 150 is moved to screening When keeping off certain a part of indoor set heat exchanger 160, relatively large windage can be produced in the regional area, influences the regional area Heat exchange efficiency.So that indoor set heat exchanger 160 produces local temperature difference, the problems such as condensation easily occurs or freezes, change it Hot reduced capability.
Figure 14 is showing for the indoor set heat exchanger 160 of wall-hanging air conditioner indoor unit 100 according to an embodiment of the invention It is intended to.Referring to Figure 14, to solve the above problems, in some alternative embodiments of the present invention, heat exchanger 160 has multiple heat exchange Region and at least one electric expansion valve 161, and be configured to according to the position adjustments electric expansion valve 161 of purification assembly 150 Aperture enters the coolant quantity of multiple heat exchange areas to control.
Electric expansion valve 161 can be multiple.The particular number of electric expansion valve 161 can be with the quantity phase of heat exchange area Together, so that each heat exchange area is respectively provided with an electric expansion valve 161 on the other side, so as to by corresponding thereto 161 direct adjustment control of electric expansion valve enter its in refrigerant input quantity, so as to adapt to each heat exchange area due to windage not The heat exchange efficiency of difference is produced together, and then make it that the heat transfer effect of the regional of heat exchanger 160 is roughly the same.
The quantity of multiple heat exchange areas is two, respectively positioned at the first heat exchange area of the lower section of air inlet 121 and is located at The second heat exchange area below the front side in the forward position of air inlet 121, i.e., region corresponding to the inner side of front panel 130.
Purification assembly 150 by drive device 140 driving be moved to the inner side of air inlet 121 when, purification assembly 150 cover into Air port 121, now the location of purification assembly 150 is first position, and the downstream in the air intake path of air inlet 121 is first Heat exchange area.
When purification assembly 150 is moved to the inner side of front panel 130 by the driving of drive device 140, air inlet 121 appears.This When, the position of purification assembly 150 is the second place, and region corresponding to the inner side of front panel 130 is the second heat exchange area.
Heat exchanger 160 can have for total diversion pipeline 162 of guiding refrigerant inflow and for respectively to the first heat exchange Region and the first diversion pipeline 163 and the second diversion pipeline 164 of the second heat exchange area conveying refrigerant.Electric expansion valve 161 can Be arranged at the input of the first diversion pipeline 163 or the second diversion pipeline 164, with regulation into the first diversion pipeline 163 and/or The coolant quantity of second diversion pipeline 164.
For purification assembly 150 under purification pattern, purification assembly 150 is moved to covering air inlet by the driving of drive device 140 121 position, with the air wind purifying to the machine of getting in 100.Now, positioned at the inner side of purification assembly 150, air inlet 121 First heat exchange area of lower section is influenceed more obvious by the windage of purification assembly 150.Thus, it is desirable to limit the heat exchange of inflow first The refrigerant in region, and/or increase flow into the refrigerant of the second heat exchange area.
When indoor air quality is slightly good, user does not require that the purification assembly 150 of indoor set 100 starts purification pattern When, purification assembly 150 drives the position by the inner side of 121 inner side front panel of air inlet 130 to move by drive device 140, purification Component 150 not with surrounding air bump contact, to reduce or avoid and air contact as far as possible.Now, positioned at purification assembly 150 Rear side, be approximately perpendicular to the place plane of air inlet 121 the second heat exchange area influenceed by the windage of purification assembly 150 it is more bright It is aobvious.Thus, it is desirable to the refrigerant for flowing into the second heat exchange area is limited, and/or increase flows into the refrigerant of the first heat exchange area.
It that is to say, according to the different shift positions of purification assembly 150, heat exchanger 160 can correspondingly mark off different change Thermal region.Further, when the position of purification assembly 150 changes, indoor set 100 can be each by directly adjusting immediately The refrigerant input quantity of heat exchange area, so as to which the heat transfer effect for promptly making heat exchanger 160 overall is equalized, avoid heat exchanger 160 there is the excessive phenomenon of local temperature difference.
In some optional embodiments, the quantity of electric expansion valve 161 can be one.The electric expansion valve 161 can Be arranged on the input of the second diversion pipeline 164, and be configured to when purification assembly 150 by drive device 140 driving be moved into During 121 inner side of air port, electric expansion valve 161 increases its aperture to the first aperture.It that is to say, when purification assembly 150 is located at first During position, the air-flow that its windage passes through the first heat exchange area is reduced, and then makes the refrigerant heat exchange amount in the first heat exchange area Reduce.Now, electric expansion valve 161 can increase its aperture, so that the refrigerant for flowing into the second heat exchange area increases, flow into first The refrigerant of heat exchange area is reduced.As a result, the heat exchange pressure and heat exchange efficiency of the first heat exchange area and the second heat exchange area with The air quantity for flowing through it is adapted so that the heat transfer effect both it is equalized.
Correspondingly, when purification assembly 150 is moved to the second place by drive device 140, electric expansion valve 161 reduces it Aperture is extremely less than the second aperture of the first aperture.It that is to say, is passed through positioned at the windage of the purification assembly 150 of the second place The air-flow of two heat exchange areas is reduced, and then reduces the refrigerant heat exchange amount in the second heat exchange area.Now, electric expansion valve 161 Its aperture can be reduced, so that the refrigerant for flowing into the second heat exchange area is reduced, the refrigerant for flowing into the first heat exchange area increases.By This so that the heat transfer effect of the first heat exchange area and the second heat exchange area is equalized.
Specifically, because the first heat exchange area below air inlet 121 is compared to positioned at the inner front side of case 120 Second heat exchange area is easier to touch more surrounding air, and heat exchange efficiency is of a relatively high.Therefore, can be by electric expansion valve 161 be set directly at for the second heat exchange area convey refrigerant the second diversion pipeline 164 input, so as to limit in advance into Enter the refrigerant input quantity of the second heat exchange area, with prevention or appropriate limitation 160 issuable heat transfer effect of indoor set heat exchanger It is unbalanced.
In some alternative embodiments, the number of the heat exchange area of indoor set heat exchanger 160 can also be more than two Other numerical value.Correspondingly, the shift position of purification assembly 150 also can further be segmented.In the present embodiment, purification assembly 150 Multiple shift positions can correspond to the preferable refrigerant input quantity of multigroup each heat exchange area respectively.It that is to say, exchanged heat for indoor set The situation for a variety of heat exchange efficiencies inequality that device 160 is likely to occur, sets corresponding refrigerant input quantity shunt ratio, so that right respectively The regulation of refrigerant input quantity is more accurate rapid in each branch line of indoor set heat exchanger 160.
The present embodiment is by the way that electric expansion valve 161 to be arranged on to the input of the second diversion pipeline 164 of the second heat exchange area End so that when the position of purification assembly 150 changes, it is only necessary to which electric expansion valve 161 changes a relatively small aperture difference and is It may be such that the heat exchange pressure of two heat exchange areas is equalized, so as to improve the governing speed of electric expansion valve 161, and cause The amplitude of accommodation of electric expansion valve 161 is more gently stablized, and extends its service life.
Further, the concrete numerical value of the first aperture and the second aperture can be set according to the actual use situation of indoor set 100 Put.In some embodiments of the invention, the first aperture can be any opening degree value between 70~80%.Such as can be 70%th, 72%, 74%, 76%, 78% or 80% etc..Second aperture can be any opening degree value between 15~50%, such as Can be 15%, 20%, 25%, 30%, 35%, 40%, 45% or 50% etc..
In some embodiments of the invention, indoor set heat exchanger 160 has the housing of three-stage, and housing is set including level Put the first heat exchanging segment 165 below air inlet 121, side-lower extension second is changed forward from the front end of the first heat exchanging segment 165 Hot arc 166 and the 3rd heat exchanging segment 167 extended vertically downwards from the lower end of the second heat exchanging segment 166.The He of first diversion pipeline 163 Second diversion pipeline 164 is each configured to access case 120 from the second heat exchanging segment 166.
It that is to say, the input of the first diversion pipeline 163 and the second diversion pipeline 164 can be along same bearing of trend access digit In the second heat exchanging segment 166 of the middle section position of heat exchanger 160.So that refrigerant intake line mechanism is compact, take up space small.Enter One step, the pipeline inside the second heat exchanging segment 166 of the first diversion pipeline 163 and the second diversion pipeline 164 is respectively along phase Opposite direction extends, so as to avoid the refrigerant in two respective diversion pipelines in heat exchange area from influencing each other.
In some embodiments of the invention, the first heat exchanging segment 165 and at least partly the second heat exchanging segment 166 form first and changed Thermal region.Second heat exchange area of 3rd heat exchanging segment 167 and the formation of at least partly the second heat exchanging segment 166.First diversion pipeline 163 exists Bending extends upwardly to the first heat exchanging segment 165 in second heat exchanging segment 166, with whole first heat exchange areas of covering.Second mozzle The bending in the second heat exchanging segment 166 of road 164 extends downward into the 3rd heat exchanging segment 167, with whole second heat exchange areas of covering.
It that is to say, the top half of the second heat exchanging segment 166 belongs to the first heat exchange area, the lower half of the second heat exchanging segment 166 Belong to the second heat exchange area.Thus, when purification assembly 150 is between first position and the second place, it is to indoor set It is main caused by heat exchanger 160 to influence to be substantially all the input institute positioned at the first diversion pipeline 163 and the second diversion pipeline 164 The second heat exchanging segment 166 on.So that the windage of purification assembly 150 is for the first heat exchange area and the second heat exchange area The influence of heat transfer effect is more similar.Thus, the input of the first diversion pipeline 163 and the second diversion pipeline 164 is respectively provided with It the middle section position of machine heat exchanger 160 indoors, can both reduce the amplitude of accommodation of the aperture of electric expansion valve 161, its tune can be reduced again Save number so that the operation of indoor set heat exchanger 160 is more stable.
In some embodiments of the invention, it is respectively arranged with the outer surface of the first heat exchange area and the second heat exchange area First temperature sensor and second temperature sensor (not shown), to detect the first surface temperature of the first heat exchange area respectively Degree and the second surface temperature of the second heat exchange area.Further, electric expansion valve 161 can be configured to when first surface temperature and When the difference of second surface temperature is more than a default temperature gap, electric expansion valve 161 increases or reduced a default aperture Value.
It that is to say, the aperture of electric expansion valve 161 can carry out instant tune according to the shift position of purification assembly 150 first Save (increase to the first aperture or be decreased to the second aperture).Then, among the process that machine heat exchanger 160 is run indoors, electronics Expansion valve 161 can also carry out real according to the first surface temperature and second surface temperature of the first heat exchange area and the second heat exchange area When adjustment so that the heat transfer effect in 160 each region of indoor set heat exchanger persistently maintains roughly the same level, ensure The using effect of user.
Specifically, the temperature gap of first surface temperature and second surface temperature can be according to indoor set heat exchanger 160 Performance, purification pattern of indoor set 100 etc. are further set.In some embodiments of the invention, the temperature gap can be with For the arbitrary temp value between 0.5~2 DEG C.Such as it can be 0.5 DEG C, 0.7 DEG C, 0.9 DEG C, 1 DEG C, 1.5 DEG C, 2 DEG C etc..At some In preferred embodiment, the temperature gap can be preferably 1 DEG C, to ensure each area surface temperature of indoor set heat exchanger 160 not Can have big difference, and the regulation of the aperture of electric expansion valve 161 can be avoided excessively frequent.
In some embodiments of the invention, it is more than temperature gap in the difference of first surface temperature and second surface temperature In the case of, electric expansion valve 161 is configured to：When first surface temperature is less than second surface temperature, electric expansion valve 161 increases Big opening value.When first surface temperature is more than second surface temperature, electric expansion valve 161 reduces opening value.Specifically, preset Aperture regulation value can be 1~10% between arbitrary value.Such as can be 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%th, 9% or 10% etc..
It that is to say, when the aperture of electric expansion valve 161 has carried out first regulation according to the shift position of purification assembly 150 Afterwards, indoors in the course of work of machine heat exchanger 160, the heat transfer effect of the first heat exchange area and the second heat exchange area may be by There is less difference in the influence of the factor such as indoor environment residing for air-conditioner indoor wall on-hook, so as to cause heat exchanger surface temperature not It is balanced.Now, according to the surface temperature difference of 160 each heat exchange area of indoor set heat exchanger, electronic expansion is adjusted more by a small margin The aperture of valve 161, it is possible to achieve real-time monitoring is carried out to refrigerant input quantity in indoor set heat exchanger 160, eliminates indoor set rapidly Local temperature difference on heat exchanger 160.Especially, this fine setting can also be the first regulation such as the first aperture of optimization, the second aperture Shi Suoxu default opening value provides data and supports that pole contributes to the perfect in shape and function of air-conditioner indoor wall on-hook.
In some real-time examples of the present invention, indoor apparatus of air conditioner 100 also includes liquid separation adjusting means 70, is arranged at total water conservancy diversion The upstream of the downstream of pipeline 162, the first diversion pipeline 163 and the second diversion pipeline 164.

It that is to say, when the refrigeration of two heat exchange areas is similar, the heat exchange pressure of the two is also more balanced, so that The first sub-chamber and second sub-chamber's fluid pressure that must be connected respectively with two heat exchange areas are roughly equal.Thus, when When pressure in one sub-chamber and the second sub-chamber is equal, elastic component 700 will not be by perpendicular active force, or the effect Power is much smaller than the screen resilience of its own, so as to avoid producing gap between movable part 720 and fixed part 710 or shunting cavity wall, And then prevent in the first sub-chamber and the second sub-chamber produce fluid communication so that two heat exchange areas be able to maintain that it is current compared with For the heat transfer effect of equilibrium, avoid it from the appearance of the excessive situation of local temperature difference occur, enhance the stability of heat exchanger operation.
Further, the part (hereinafter referred to as connecting portion) being connected with shunting cavity wall of fixed part 710 is relative to work Move the (following with least part inner circumferential side ora terminalis of fixed part 710 and/or the part adjacent with the inwall of branch chamber of portion 720 Abbreviation adjacency section) input port away from branch chamber reception refrigerant.
Thus, when the pressure in the first sub-chamber and the second sub-chamber is unequal, the first sub-chamber and the second sub-chamber Pressure difference can cause flexure strip by perpendicular active force.When the active force is more than the screen resilience of elastic component 700 itself, Gap is produced between movable part 720 and shunting cavity wall, the first sub-chamber and the second sub-chamber are interconnected, and produce fluid friendship Change to adjust the amount of the refrigerant respectively enterd in the first sub-chamber and the second sub-chamber.
When purification assembly 150 is purifying mobile handoff between position and non-purification position, it is produced to two heat exchange areas Raw windage is different, and then causes the heat exchange efficiency of two heat exchange areas difference occur.
Specifically, when purification assembly 150 is located at the air intake path upstream of the first heat exchange area connected with the first sub-chamber When, the windage increase of first heat exchange area, heat exchange efficiency reduces, and its interior refrigerant temperature is gradually less than in the second heat exchange area Refrigerant temperature so that the first heat exchange area fluid pressure is gradually less than the Fluid pressure in the second heat exchange area.
Correspondingly, the Fluid pressure in the first sub-chamber connected with the first heat exchange area is gradually less than and the second heat transfer zone Fluid pressure in second sub-chamber of domain connection.When active force caused by the fluid pressure differential of Liang Ge sub-chamber is more than elastic component During 700 itself screen resilience, one end stress positioned at adjacency section of movable part is bent to the first small sub-chamber of Fluid pressure, from And make it that cross-sectional area of first sub-chamber at the refrigerant input port of branch chamber reduces, and cause close point of the second sub-chamber Flow the cross-sectional area increase at the refrigerant input port of chamber.Thus, the bootable relatively more refrigerants of the movable part 720 of bending flow into Second sub-chamber, and the coolant quantity flowed into the first sub-chamber is limited, so that the first heat exchange connected with the first sub-chamber The temperature difference and heat exchange pressure differential of region and the second heat exchange area connected with the second sub-chamber are gradually reduced, until the first sub- chamber Active force caused by the pressure differential of room and the second sub-chamber is less than the screen resilience of elastic component 700.
