The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
In an embodiment of the present invention, the outer shape of cabinet air-conditioner is unrestricted, for example, may include round cabinet-type air conditioner or The cabinet-type air conditioner of rectangle cabinet-type air conditioner or other shapes is round cabinet air-conditioner according to an embodiment of the invention as shown in Figure 1 Schematic diagram, the indoor unit 200 of cabinet air-conditioner include shell 201, and the rear wall of shell 201 is provided with air inlet, before shell 201 Side wall is provided with air outlet 202, and air outlet 202 extends in upward and downward, has connection air inlet and air outlet 202 in shell 201 Air duct, be provided with heat exchanger, and fan such as aerofoil fan can be also set in air duct, wherein air outlet 202 is vertically Direction is divided into N sections of wind-guiding regions, and example is divided into three sections of wind-guiding regions 1,2,3 as shown in figure 1, and each wind-guiding region setting is multiple to be led Wind unit such as wind guide strip, heat exchanger include N number of heat exchange subregion divided according to refrigerant flow path, and N number of heat exchange subregion is led with N sections The corresponding distribution in wind region, such as according to three heat exchange three road refrigerant flow paths of subregion, that is, heat exchanger of setting shown in Fig. 1, and install In position substantially corresponding with three sections of wind-guiding regions.
Wherein, N is the positive integer, such as N=2 or 3 or 4 or 5 or 6 etc. greater than 1, and still, the heat exchange subregion of heat exchanger is The quantity of the coil pipe of flow path should not be excessive, and otherwise tube side of the refrigerant in each heat exchange area is shorter, and refrigerant heat exchanger is insufficient, Heat exchange efficiency decline, heat exchange subregion, that is, flow path coil pipe quantity is unsuitable very few, and otherwise refrigerant is longer in the tube side of each coil pipe, Resistance is excessive, also will affect heat exchange efficiency.Therefore in order to ensure refrigerant can sufficiently exchange heat in heat exchange subregion, it is preferable that N ∈ [2,4]。
The method of the cabinet type air conditioning exhausting temperature of control of embodiment according to a first aspect of the present invention is described with reference to the accompanying drawings.
Fig. 2 is the flow chart of the method for the cabinet type air conditioning exhausting temperature of control according to an embodiment of the invention, such as Fig. 2 Shown, the method for the embodiment of the present invention includes:
S1, the temperature of N number of heat exchange subregion of heat collecting exchanger.
For example, temperature sensor can be set, the flow path coil pipe of the heat exchange subregion of heat exchanger is detected by temperature sensor Middle part temperature, using the temperature as corresponding heat exchange subregion.
S2, the size relation of the temperature of more N number of heat exchange subregion.
S3 adjusts the wind-guiding angle of the wind deflector unit in N sections of wind-guiding regions according to the size relation of the temperature of N number of heat exchange subregion Degree, so that the leaving air temp in N number of wind-guiding region is uniform.
Specifically, if there are size deviations for the temperature of N number of heat exchange subregion, then it is assumed that each under current wind-guiding angle The leaving air temp in wind-guiding region will be uneven, in order to avoid sense of discomfort caused by leaving air temp unevenness, can be led by adjusting Wind angle carrys out regulating outlet air temperature.For example, in a heating mode, in the temperature unevenness of N number of heat exchange subregion, reducing leaving air temp The wind-guiding angle of the wind deflector unit in relatively low wind-guiding region, alternatively, regulating outlet air temperature deviation is more than the wind-guiding area of fiducial temperature The wind-guiding angle of the wind deflector unit in domain, until the leaving air temp in the wind-guiding region tends to limit the temperature difference range, the wind-guiding region Leaving air temp gradually rises, while the air quantity in the wind-guiding region of other positions becomes larger, and leaving air temp accordingly also can decrease, most It can achieve the effect for adjusting the leaving air temp in each wind-guiding region eventually;Alternatively, in cooling mode, in N number of heat exchange subregion When temperature unevenness, the wind-guiding angle of the wind deflector unit in the higher wind-guiding region of leaving air temp can reduce, can achieve reduction should The effect of the leaving air temp in wind-guiding region, while the leaving air temp of other positions can also be influenced, thus can make each A leaving air temp region is average.In short, the wind-guiding angle by adjusting wind deflector unit passes through outlet air come regulating outlet air temperature Mouthful up and down Boiler pressure control come so that the leaving air temp in each wind-guiding region reach uniformly, guarantee comfort.
The method of the cabinet type air conditioning exhausting temperature of control according to an embodiment of the present invention corresponds to N based on N number of heat exchange subregion is arranged Section wind-guiding region, the wind deflector unit by adjusting according to the size relation of the temperature of N number of heat exchange subregion N sections of wind-guiding regions are led Wind angle can make leaving air temp uniform, improve comfort.
Above method, which can be applied to refrigeration mode, also can be applied to heating mode, still, outlet air in cooling mode The size deviation of temperature is unobvious, and the influence to comfort is little, and in a heating mode, the leaving air temp of cabinet air-conditioner it is inclined Difference is often bigger, and the effect of above method becomes apparent from.
Below by taking heating mode as an example, N sections of wind-guiding regions are adjusted to the size relation of the temperature according to N number of heat exchange subregion The process of the wind-guiding angle of wind deflector unit further illustrates.
In some embodiments, in a heating mode, when the temperature of N number of heat exchange subregion is there are when size deviation, according to pre- If angular width degree reduces the wind-guiding angle of the wind deflector unit in the corresponding wind-guiding region of the smallest heat exchange subregion of temperature in N number of heat exchange subregion Degree, to achieve the purpose that improve the leaving air temp in the wind-guiding region, until the leaving air temp in the wind-guiding region is in prescribed limit It is interior, while the leaving air temp of other positions is influenced, so that the leaving air temp in each wind-guiding region tends to be average.
Specifically, it is illustrated in figure 3 the signal of the wind-guiding control in three wind-guiding regions of the round cabinet-type air conditioner for Fig. 1 Figure, wherein (1) schematic diagram all closed for the wind deflector unit in three sections of wind-guiding regions;It (2) is the wind-guiding list in top wind-guiding region First schematic diagram all closed and the wind deflector unit in the wind-guiding region of middle part and lower part is opened;It (3) is leading for three sections of wind-guiding regions The fully open schematic diagram of wind unit;(4) wind deflector unit for top wind-guiding region is opened and middle part and lower part wind-guiding region The schematic diagram that wind deflector unit is closed.
It is illustrated with Fig. 1 and three sections of wind-guiding regions shown in Fig. 3, wherein corresponding three sections of wind-guiding regions are installed by heat exchanger Three heat exchange subregions, such as pass through three flow path coil pipes and realize.Specifically, cabinet air-conditioner enters heating mode, heat exchanger Each flow path will show different temperature, best the result is that the middle portion temperature of three flow path coil pipes is identical, then outlet air The temperature of mouth will uniformity.But in most instances, leaving air temp is different, due to freezing in cooling cycle system The complexity of agent flowing, alternatively, the variation of indoor lateral operating condition, causes each flow path to shunt uneven, thus each flow path coil pipe Middle part temperature it is variant.For example, the temperature of the top heat exchange subregion of heat exchanger is 50 DEG C, the temperature of middle part heat exchange subregion is 53 DEG C, the temperature of lower part heat exchange subregion is 45 DEG C, it is considered that, the leaving air temp in lower part wind-guiding region is lower, then according to default For example every step angular width degree of angular width degree is 2 °, and the aperture for gradually adjusting the wind guide strip in lower part wind-guiding region reduces, until lower part wind-guiding The temperature difference △ T of the outlet air temperature difference in region meets within T≤3 DEG C △, while the leaving air temp in the wind-guiding region at top and middle part Meeting corresponding change, so that the leaving air temp in three wind-guiding regions gradually tends to be average.Three sections of wind-guiding areas are adjusted by above method The leaving air temp in domain, it can be ensured that leaving air temp is uniform, improves comfort.
In further embodiments, in order to avoid continually carrying out the adjusting of wind-guiding angle, temperature difference threshold can be set, Leaving air temp deviation carries out the adjusting of wind-guiding angle again when reaching setting temperature difference threshold.Specifically, in a heating mode, N is obtained Maximum temperature in the temperature of a heat exchange subregion;Calculate maximum temperature in N number of heat exchange subregion in addition to changing with maximum temperature The temperature difference of the temperature of N-1 heat exchange subregion except hot subregion.Still by taking N=3 as an example, set top heat exchange subregion temperature as T1, middle part heat exchange subregion temperature be T2, the temperature of lower part heat exchange subregion is T3, then T1-T2=Δ T1, T1-T3=Δ T2.
Further, in some embodiments, the temperature difference heat exchange beyond fiducial temperature point in N-1 heat exchange subregion is determined Area;Reduce the wind-guiding of the wind deflector unit in heat exchange subregion corresponding wind-guiding region of the temperature difference beyond fiducial temperature according to preset angle amplitude Angle.For example, set fiducial temperature as 4 DEG C, if Δ T1 > 4 DEG C or Δ T2 > 4 DEG C, it is gradually reduced with 5 ° of angular width degree The wind-guiding angle of the wind guide strip in portion wind-guiding region or lower part wind-guiding region, until Δ T1 < 4 DEG C or Δ T2 < 4 DEG C, so that The leaving air temp in each wind-guiding region within the limits prescribed, keeps uniformity, improves comfort.
In further embodiments, it determines the maximum temperature difference in the N-1 temperature difference, reduces N-1 according to preset angle amplitude and change The wind-guiding angle of the wind deflector unit in the corresponding wind-guiding region of heat exchange subregion in hot subregion with the maximum temperature difference.For example, if Δ T1 > 4 DEG C and Δ T2 > 4 DEG C, wherein if Δ T1 > Δ T2, middle part wind-guiding region is first gradually reduced with 5 ° of angular width degree The wind-guiding angle of wind guide strip then adjust the leaving air temp of lower part again until Δ T1 < 4 DEG C, until Δ T2 < 4 DEG C;Alternatively, because The leaving air temp that also will affect other positions for the adjusting of wind-guiding angle can repeat after having adjusted middle part leaving air temp Above temperature difference judgement determines the wind-guiding angle for adjusting which position according to the result of judgment, advises until leaving air temp is in In fixed range, reach the uniform purpose of leaving air temp.
Based on above description, by taking Fig. 1 and three sections of wind-guiding regions shown in Fig. 3 and three heat exchange subregions as an example, Fig. 4 is basis The flow chart of the method for the cabinet type air conditioning exhausting temperature of control of one embodiment of the present of invention, as shown in figure 4, specifically including:
S400, into heating mode.
S401, stable after preset time such as 15 minutes, temperature collection T1, T2 and T3 improve accuracy.
S402, judge three heat exchange subregion temperature size relation, obtain Δ T1 and Δ T2, and enter step S403 or S405 or S407.
S403, Δ T1 > 4 DEG C or Δ T2 > 4 DEG C.
S404 is gradually reduced the wind-guiding angle of the wind guide strip in middle part wind-guiding region or lower part wind-guiding region with 5 ° of angular width degree Degree, until Δ T1 < 4 DEG C or Δ T2 < 4 DEG C, and enters step S408.
S405, Δ T1 > 4 DEG C and Δ T2 > 4 DEG C.
S406 can first be led if Δ T1 > Δ T2 with the wind guide strip that 5 ° of angular width degree is gradually reduced middle part wind-guiding region Wind angle until Δ T1 < 4 DEG C, then adjusts the wind-guiding angle of the wind guide strip in lower part wind-guiding region, until Δ T2 < 4 DEG C, alternatively, such as Fruit Δ T2 > Δ T1, the then leaving air temp that can first adjust lower part wind-guiding region adjust the leaving air temp in middle part wind-guiding region again, directly It is in prescribed limit to leaving air temp, and enters step S408.
S407, Δ T1 < 4 DEG C and Δ T2 < 4 DEG C.
S308 maintains the statusquo.
In short, the method for the cabinet type air conditioning exhausting temperature of control of the embodiment of the present invention, by monitoring each heat exchange point The temperature in area controls the wind-guiding angle of the wind deflector unit in corresponding wind-guiding region according to the size relation of the temperature of N number of heat exchange subregion Degree avoids leaving air temp deviation larger that is, by the intelligent control of the air quantity above and below air outlet, promotes human sense of comfort.
