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.
Purification assembly 150 is driven the position in the position away from air inlet 121 and masking air inlet 121 by drive device 140 Moved between putting, when being not turned on purification function, purification assembly 150 removes air inlet 121, moves to away from air inlet 121 Position, now, purification assembly 150 are in non-purification position；After purification function is opened, purification assembly 150 is by drive device band It is dynamic, masking air inlet 121 position is moved to, now, purification assembly 150 is in purification position, to the air-flow of the machine of getting in 100 Purified.
Because purification assembly 150 is when purifying position and non-purification position, the windage that indoor set blower fan produces air-flow is obvious Difference, after purification function is opened, air-flow necessarily causes the heat transfer effect decay by heat exchanger 160, easily gone out by filtering Existing high load capacity problem, can accordingly be controlled according to the operational mode of air conditioner, air conditioner is reduced in purification to air-conditioning The normal refrigeration of device or the influence of heat-production functions.
Such as after purification function is opened, the target tube temperature of the Tube Sheet of Heat Exchanger temperature of indoor set 100 can be set, and examine in real time The Tube Sheet of Heat Exchanger temperature of indoor set 100 is surveyed, the refrigeration system of air conditioner is carried out according to the temperature difference of detection pipe temperature and target tube temperature anti- Feedback control.
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 the blower fan of indoor set 100 according to difference, Tube Sheet of Heat Exchanger temperature temperature is lower, room The rotation speed of fan of interior machine 100 is faster.If the lifting of the rotation speed of fan of indoor set 100 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 heat exchange temperature of indoor set 100 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 the blower fan of indoor set 100 according to difference, Tube Sheet of Heat Exchanger temperature temperature is got over Height, the rotation speed of fan of indoor set 100 are faster.If the lifting of the rotation speed of fan of indoor set 100 cannot be guaranteed that Tube Sheet of Heat Exchanger temperature maintains When within the first temperature difference threshold, then increasing the aperture of the throttling arrangement of compression kind of refrigeration cycle with the target tube temperature temperature difference, if Still it cannot be guaranteed that Tube Sheet of Heat Exchanger temperature is maintained with the target tube temperature temperature difference when within the second temperature difference threshold, then compressor is dropped Frequently, there is high load capacity so as to prevent the heat exchange temperature of indoor set 100 too high.
Above-mentioned first temperature difference threshold and the second temperature difference threshold can be according to the specifications and requirement of the heat exchanger of indoor set 100 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 changed by drive device driving between purification pattern and non-purification pattern, purification Component 150 and the vertical range relative close on the surface of heat exchanger 160.Thus, certain part is blocked when purification assembly 150 is moved to During heat exchanger 160, relatively large windage can be produced in the regional area, influences the heat exchange efficiency of the regional area.So that Obtain heat exchanger 160 and produce local temperature difference, the problems such as condensation easily occurs or freezes, weaken its exchange capability of heat.
Figure 11 is the schematic diagram of the heat exchanger 160 of wall-hanging air conditioner indoor unit 100 according to an embodiment of the invention.
To solve the above problems, the present invention some alternative embodiments in, heat exchanger 160 have multiple heat exchange areas and At least one electric expansion valve 161, and be configured to according to the aperture of the position adjustments electric expansion valve 161 of purification assembly 150 with Control enters the coolant quantity of multiple heat exchange areas.
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 Below the front side in the forward position of air inlet 121 (the second heat exchange area is region corresponding on the inside of front panel)；
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, now the location of purification assembly 150 is first position, and the downstream in the air intake path of air inlet 121 is first to change Thermal region.
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.Now, region corresponding to front panel inner side 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.
Purification assembly 150 under purification pattern, purification assembly 150 by drive device 140 driving be moved to it is completely obscured enter The position in air port 121, with the air wind purifying to the machine of getting in 100.Now, positioned at the inner side of purification assembly 150, air inlet First heat exchange area of 121 lower sections is influenceed more obvious by the windage of purification assembly 150.Thus, it is desirable to limit inflow first The refrigerant of heat exchange area, and/or increase flow into the refrigerant of the second heat exchange area.
When indoor air quality is slightly good, and user does not require that the purification assembly of indoor set 100 starts purification pattern, only Change component 150 drives the position by the inner side of position front panel 130 of completely obscured air inlet 121 to move by drive device 140, Not with the position of 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 can be immediately by directly adjusting each change The refrigerant input quantity of thermal region, 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 The input of the second diversion pipeline 164 is arranged on, and is configured to when purification assembly 150 is moved to screening by the driving of drive device 140 When covering the position of air inlet 121, electric expansion valve 161 increases its aperture to the first aperture.It that is to say, when purification assembly 150 When first position, the air-flow that its windage passes through the first heat exchange area is reduced, and then makes the refrigerant in the first heat exchange area Heat exchange amount reduces.Now, electric expansion valve 161 can increase its aperture, so that the refrigerant for flowing into the second heat exchange area increases, flow The refrigerant for entering the first heat exchange area is reduced.As a result, the first heat exchange area and the heat exchange pressure of the second heat exchange area and heat exchange Efficiency is adapted with flowing through its air quantity 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, due to positioned at the first heat exchange area of the lower section of air inlet 121 compared to the on front side of casing interior Two heat exchange areas are easier to touch more surrounding air, and heat exchange efficiency is of a relatively high.Therefore, can be by electric expansion valve 161 The input for the second diversion pipeline 164 that refrigerant is conveyed for the second heat exchange area is set directly at, so as to limit entrance in advance The refrigerant input quantity of second heat exchange area, it is unbalanced with prevention or appropriate limitation 160 issuable heat transfer effect of heat exchanger.
In some alternative embodiments, the number of the heat exchange area of heat exchanger 160 can also be other numbers more than two Value.Correspondingly, the shift position of purification assembly 150 also can further be segmented.In the present embodiment, purification assembly 150 is multiple Shift position can correspond to the preferable refrigerant input quantity of multigroup each heat exchange area respectively.It that is to say, be likely to occur for heat exchanger 160 The uneven situation of a variety of heat exchange efficiencies, corresponding refrigerant input quantity shunt ratio is set respectively, so that heat exchanging device 160 is each The regulation of refrigerant input quantity is more accurate rapid in branch line.
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. In some embodiments of the invention, the first aperture can be any opening degree value between 70~80%.Such as can be 70%, 72%th, 74%, 76%, 78% or 80% etc..Second aperture can be any opening degree value between 15~50%, such as can be 15%th, 20%, 25%, 30%, 35%, 40%, 45% or 50% etc..
In some embodiments of the invention, heat exchanger 160 have three-stage housing, housing include be horizontally set on into First heat exchanging segment 165 of the lower section of air port 121, the second heat exchanging segment 166 from the side-lower extension forward of the front end of the first heat exchanging segment 165 And the 3rd heat exchanging segment 167 extended vertically downwards from the lower end of the second heat exchanging segment 166.First diversion pipeline 163 and second is led Flow tube road 164 is each configured to access case 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, its heat exchanging device Caused by 160 it is main influence to be substantially all where the input of the first diversion pipeline 163 and the second diversion pipeline 164 the On two heat exchanging segments 166.So that heat exchange effect of the windage of purification assembly 150 for the first heat exchange area and the second heat exchange area The influence of fruit is more similar.Thus, the input of the first diversion pipeline 163 and the second diversion pipeline 164 is arranged at heat exchange It the middle section position of device 160, can both reduce the amplitude of accommodation of the aperture of electric expansion valve 161, it can be reduced again and adjust number so that changed The operation of hot device 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 heat exchanger 160 is run, electric expansion valve 161 can also be adjusted in real time according to the first surface temperature and second surface temperature of the first heat exchange area and the second heat exchange area It is whole, so that the heat transfer effect in 160 each region of heat exchanger persistently maintains roughly the same level, it ensure that the use of user Effect.
Specifically, the temperature gap of first surface temperature and second surface temperature can be according to heat exchanger 160 performance, room Purification pattern of interior machine etc. is further set.In some embodiments of the invention, the temperature gap can be 0.5~2 DEG C Between arbitrary temp value.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..In some preferred embodiments In, the temperature gap can be preferably 1 DEG C, to ensure that each area surface temperature of heat exchanger 160 will not have big difference, and can keep away The regulation for exempting from the aperture of electric expansion valve 161 is 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, in the course of work of heat exchanger 160, the heat transfer effect of the first heat exchange area and the second heat exchange area may be by air conditioning chamber There is less difference in the influence of the factor such as indoor environment residing for interior wall hanging machine, so as to cause heat exchanger surface temperature unbalanced. Now, according to the surface temperature difference of 160 each heat exchange area of heat exchanger, the aperture of electric expansion valve 161 is adjusted more by a small margin, It can realize that refrigerant input quantity carries out real-time monitoring, the rapid local temperature difference eliminated on heat exchanger 160 in heat exchanging device 160.It is special Not, required default opening value provides number when this fine setting can also be adjusted for the first aperture of optimization, the second aperture etc. are first According to support, 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.
Figure 12 is the schematic elevational view of liquid separation adjusting means 70 according to an embodiment of the invention, and Figure 13 is according to this The schematic cross sectional views of the liquid separation adjusting means 70 of invention one embodiment.
Referring to Figure 12, liquid separation adjusting means 70 has branch chamber, and an elastic component 700 is provided with branch chamber with by inside it Space is divided into the first sub-chamber and the second sub-chamber, to accommodate the refrigerant at least partly flowing into branch chamber respectively.Specifically, liquid separation Adjusting means 70 also includes total diversion pipeline 162, the first diversion pipeline 163 and the second mozzle connected with its refrigerant input port Road 164.Total diversion pipeline 162 is configured to guiding refrigerant and enters branch chamber.First diversion pipeline 163 is configured to and the first sub-chamber Connection, to guide the refrigerant outflow liquid separation adjusting means 70 in the first sub-chamber.Second diversion pipeline 164 is configured to and the second son Chamber, to guide the refrigerant outflow liquid separation adjusting means 70 in the second sub-chamber.
