Foretell air conditioner air-out device, when the air conditioner air-out, the air that can pass through gas acceleration rate structure 4 forms the negative pressure with higher speed, thereby form the suction to the air of luring the 5 import departments in wind channel, make the air outside the wind channel of luring 5 can enter into mixing mouth 6 departments along luring wind channel 5, form the mixture with the air with higher speed, lure the air after mixing to get into heat accumulation device 8, partly pass through heat accumulation device 8, partly is intercepted, the air after the interception produces the backward flow in both sides, and pass through heat accumulation device 8 of pressure effect through both sides, make the air pressure distribution that blows off behind heat accumulation device 8 more even, the air-out wind speed is more even, user's use experience has been improved. Because the mixing opening 6 of the air conditioner air-out device and/or the speed-increasing opening width of the gas speed-increasing structure 4 can be adjusted, different induced air percentage combinations can be formed, different air conditioner air-out temperatures can be formed by different percentage combinations, induced air percentage can be adjusted as required, and then the air-out temperature of the air conditioner air-out device can be adjusted, the problem that the air-out temperature of a radiation air conditioner is inconvenient to adjust is effectively solved, the air-out temperature can be reasonably adjusted according to the current indoor temperature, the air conditioner load is reduced, and the air conditioner energy consumption is saved.
Preferably, in this embodiment, the mixing opening 6 and the speed-increasing opening width of the gas speed-increasing structure 4 can be adjusted, so that a wider range of induced air percentage can be formed by combining the mixing opening 6 and the gas speed-increasing structure, and more accurate and rapid adjustment of the air outlet temperature can be realized.

Regarding the mixing port 6, the channel outer wall of the induction duct 5 mainly forms the mixing port 6, and the width of the mixing port 6 is the minimum distance between the two side walls on both sides of the mixing port 6 in the width direction. Therefore, it is only necessary to make the interval between the side walls of the induction duct 5 forming the width direction of the mixing port 6 adjustable. Specifically, the sliding fit between any one of the side walls and the straight wall on the corresponding side thereof can be formed, and the sliding position of the side wall relative to the straight wall can be adjusted, so that the width of the mixing port 6 formed on the outer side wall of the induction duct 5 can be conveniently adjusted, and the two side walls can be simultaneously set to be slidable relative to the straight walls on the two sides of the mixing port 6, so that the width of the mixing port 6 can be adjusted by simultaneously adjusting the sliding positions of the two side walls. The side walls on the two sides of the width direction of the mixing opening 6 are adjusted through a driving structure with a gear rack matched with a motor, or are adjusted through the stretching of a telescopic cylinder.
Preferably, the heat storage device 8 includes a heat exchanger fin 9 and a heat exchange tube 10, the heat storage material is accommodated in the heat exchange tube 10, and a communication port 11 penetrating in the thickness direction of the heat exchanger fin 9 is provided on the heat exchanger fin 9.
Because the heat storage device 8 comprises the heat exchanger fins 9, the air outlet is more uniform, and uneven air can be evenly distributed. The heat exchanger fins 9 are equivalent to porous media and have certain damping, one part of air flow passes through the porous media to weaken strong wind, the human body can comfortably accept the wind speed, the other part of air is intercepted by the heat storage devices 8, the intercepted air generates backflow at two sides and passes through the heat storage devices 8 at the two sides under the action of pressure. Because the communicating opening 11 that the thickness direction that is provided with heat exchanger fin 9 on the heat exchanger fin 9 runs through, consequently can be so that the space intercommunication between each heat exchanger fin 9, at the in-process of air flow through heat storage device 8, can form series intercommunication through communicating opening 11, make highly-compressed air can be balanced to the low pressure, thereby make the air carry out the voltage-sharing once more in heat storage device 8, make the air pressure distribution that blows out behind heat storage device 8 more even, the air-out wind speed is more even, user's use experience has been improved.
Specifically, the air storage device 1 of the air conditioner air outlet device is connected with an air supply outlet of an indoor unit, cold air or hot air blown out of the indoor unit firstly enters the air storage device 1, then enters the attraction device 2 through the air speed increasing structure 4 arranged between the air storage device 1 and the attraction device 2, and because the cross-sectional area of the air speed increasing structure 4 is smaller than that of the air supply outlet, when the cold air or the hot air passes through the air speed increasing structure 4, negative pressure is formed in the attraction device 2, so that indoor air enters the attraction air duct 5 of the attraction device 2 through the attraction air inlet of the attraction device 2, the air entering the attraction air duct 5 exchanges heat with the cold air or the hot air, then exchanges heat through the heat storage device 8, and then is discharged back to the indoor through the air outlet 7 of the attraction device 2. Through the arrangement, cold air or hot air blown out of the indoor unit can be prevented from being directly discharged into a room, and the cold air or the hot air is firstly subjected to heat exchange with indoor air in the attraction device 2 and then discharged into the room together, so that the cool but not cold and not warm but not hot comfortable effect can be achieved, and the use experience of a user is improved. The gas storage device 1 is a gas storage tank, and of course, the gas storage device 1 may also be configured as a gas storage cylinder, a gas storage box, or the like, and such adjustment and change of the specific structure of the gas storage device 1 do not depart from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.
Note that the cross-sectional area of the air speed increasing structure 4 refers to the area of the cross section through which cold air or hot air passes through the air speed increasing structure 4, and the area of the air outlet refers to the area of the cross section through which cold air or hot air passes through the air outlet. Because the volume of the cold air or the hot air passing through the air increasing structure 4 is the same as that of the cold air or the hot air passing through the air supply opening in the same time, and the cross-sectional area of the air increasing structure 4 is smaller than that of the air supply opening, the speed of the cold air or the hot air passing through the air increasing structure 4 is higher than that of the cold air or the hot air passing through the air supply opening, so that the speed increase of the air is realized, and negative pressure is formed in the attraction device 2, and the indoor air is attracted into the attraction device 2.
In this embodiment, the gas speed-increasing structure 4 is a speed-increasing opening for communicating the attraction device 2 and the gas storage device 1, and the speed-increasing opening may be directly disposed on the side wall of the attraction device 2 or directly disposed on the side wall of the gas storage device 1. Preferably, an air guide pipe is further arranged at the speed increasing port and extends towards the mixing port 6, so that the air supply distance of the speed increasing port can be increased, and a better attraction effect can be achieved. The inner diameter of the air duct should be the same as the diameter of the acceleration opening.
Preferably, the heat exchanger fins 9 are corrugated, slotted or louvered fins.
Preferably, the heat exchange tube 10 has a double-layer structure, so that a larger heat exchange area can be formed, and more heat storage material is stored in the heat storage device 8, improving the temperature regulation capability of the heat storage device 8. The heat exchange pipe 10 is, for example, a copper pipe.
In one embodiment, the heat exchange tube 10 is a U-shaped tube connected in series, and plugs are disposed at the tube openings of two ends of the heat exchange tube 10. Two adjacent U-shaped pipes are connected in series through the U-shaped bent pipe for packaging, so that the sealing performance of the heat storage material can be ensured. Because the heat storage material is filled in the heat exchange tube 10, and the heat storage material does not need to flow in other devices in a circulating way, and only needs to be kept in the heat storage device 8, the two ports of the heat exchange tube only need to be plugged by plugs to form sealing.
In another embodiment, the heat exchange tubes 10 are parallel-connected, each heat exchange tube 10 is a straight tube, and a port of each heat exchange tube 10 is provided with a plug or at least one transition port of each heat exchange tube 10 is provided with a plug. In the present embodiment, the heat exchange tubes 10 are not communicated with each other, and each heat exchange tube 10 is filled with a heat storage material.
In another embodiment, the heat exchange tube 10 is a single U-shaped tube, and two ports of each U-shaped tube are provided with plugs respectively or at least one port is provided with a plug. The end part of the U-shaped pipe can be sealed by one end and the other end through a plug. The two ports of the U-shaped pipe can also be sealed by U-shaped elbows.
Preferably, the communication port 11 is plural, and is elongated in shape extending in the width direction of the heat exchanger fin 9. Through the communication port 11 that sets up a plurality of rectangular shapes, can realize the inside air intercommunication of heat accumulation device more conveniently, guarantee the homogeneity of gas pressure distribution, guarantee the homogeneity of air-out speed.
In this embodiment, the inducing air duct 5 is L-shaped, and the inducing air inlet of the inducing air duct 5 and the inducing air outlet 7 are on the same side of the inducing device 2.
The heat storage material is paraffin or 65mol% decanoic acid and 35mol% dodecanoic acid. The heat storage material has larger specific heat capacity and strong heat storage capacity, and can adopt a phase change heat storage material in a constant temperature defrosting multi-split air conditioner and paraffin which is easier to process.
The material properties of paraffin or 65mol% decanoic acid +35mol% dodecanoic acid are shown in the following table:
referring to fig. 4 and 5 in combination, air firstly enters the air storage tank under the action of a duct machine and the like, after the air storage tank is filled, the air enters the speed increasing area, because the section of the air at the outlet of the speed increasing port is suddenly accumulated and reduced, the air speed is increased at the speed increasing port from less than 6m/s in the air storage tank to 7.5m/s, then the air enters the mixing port to form negative pressure, under the action of the negative pressure, indoor air enters from the inducing air inlet and reaches the mixing port 6 along the inducing air duct 5 to be mixed with the air outlet of the speed increasing port, then the mixed air reaches the heat storage device 8, under the shielding action of the heat storage device, a part of air is blown out after being reduced in speed and reduced in pressure through the middle part of the heat storage device 8, the other part of air enters the air equalizing air cavity formed between the inducing air duct 5 and the heat storage device 8 from two sides, under the air pressure in the equalizing air cavity, the part through heat accumulation device 8 both sides slows down the step-down, then blows out through heat accumulation device 8, because the level and smooth plane itself of heat exchanger fin 9 has the rectification effect, consequently the air velocity distribution that blows out through heat accumulation device 8 is more even, and can not produce vortex and backward flow, has effectively improved air-out efficiency.
As can be seen from fig. 4 to 6, the air blown out after being decompressed, decelerated, and rectified by the heat storage device 8 has an overall wind speed reduced to 1.2m/s or less, a wind speed of the middle portion having the highest wind speed is reduced to about 1m/s, and a wind speed of the other portions than the middle portion corresponding to the mixing port 6 does not exceed 0.5m/s, so that a breeze is basically blown out, and the user experience is better.
According to an embodiment of the present invention, the air conditioner includes an air conditioner air outlet device, and the air conditioner air outlet device is the air conditioner air outlet device.
Referring to fig. 7 to 9 in combination, according to an embodiment of the present invention, the control method of the air conditioner air outlet device includes: acquiring the induced wind percentages of different width combinations of the speed increasing port and the mixing port 6; dividing gears of an air outlet device of the air conditioner according to the acquired inducement percentage; and adjusting the air outlet device of the air conditioner to a preset gear according to the detected indoor temperature.
When the air-out control is carried out by using the air-conditioning air-out device, different induced air percentages can be formed according to different combinations of the accelerating opening and the mixing opening 6, each induced air percentage corresponds to a different air-out temperature, therefore, according to the difference value between the set indoor temperature and the current indoor temperature, the proper induced air percentage can be selected, then the width combination of the accelerating opening and the mixing opening 6 is adjusted to the width combination corresponding to the induced air percentage, the air-out temperature corresponding to the induced air percentage is matched with the difference value between the current indoor temperature and the set indoor temperature, the difference value between the air-out temperature and the current indoor temperature can be reduced, the adjustment of the air-out temperature is more flexible and convenient, the energy consumption of the air conditioner can be effectively reduced, and the working energy efficiency of the air conditioner is improved.
The step of dividing the gears of the air conditioner air outlet device according to the acquired inducement percentage comprises the following steps:
setting the induced air percentage of 0-40% as a quick refrigerating and heating gear; setting the induced air percentage of 40-60% as a normal refrigeration and heating gear; setting the induced air percentage of 60-100% as an energy-saving refrigerating and heating gear; and classifying the acquired incentive percentages according to the divided gears. The cooling and heating gear division can refer to other percentage ranges, such as three gears of 0-45%, 45-55% and 55-100%, or other gears, or can be divided into four gears or more gears, all of which can be set according to needs, and after gear grading setting is completed, the obtained incentive percentage can be classified according to the divided gears.
The step of obtaining the induced wind percentages of different width combinations of the accelerating opening and the mixing opening 6 comprises the following steps:
dividing the width of a speed increasing port into three gears, wherein the widths are a, b and c; the width of the mixing port 6 is divided into three gears, and the widths are d, e and f respectively; combining three width gears of the speed increasing port with each width gear of the mixing port 6 respectively to obtain nine gear combinations; nine gear combinations are respectively classified into three refrigerating and heating gears.
The above-mentioned a is 5mm, b is 7.5mm, c is 10mm, d is 15mm, e is 40mm, and f is 65 mm.
The induced air percentages corresponding to the different width combinations of the accelerating opening and the mixing opening 6 are shown in the following table:
from the above table we can see that by varying the width of the acceleration and mixing ports 6, the percentage of attraction is a minimum of 12% and a maximum of 84%. Different outlet air temperatures are achieved by changing the attraction percentage. According to the division rule, the inducement percentages of the rapid cooling and heating gear positions are divided into 31%, 12%, 33% and 34%, and the corresponding width combinations are (7.5, 15), (10, 15), (10, 40) and (10, 65); the inducement percentages of the normal cooling and heating gears are 58%, 50% and 52%, and the corresponding width combinations are (5, 15), (7.5, 40) and (7.5, 65); the inducement percentages of the energy-saving cooling and heating gears are 79 percent and 84 percent, and the corresponding width combinations are (5, 40) and (5, 65).
Taking refrigeration as an example, the air outlet temperature of the air conditioner is 13 ℃, and the air outlet quantity of the air conditioner is 300m3The indoor temperature is 27 ℃, and the corresponding air outlet temperature can be calculated by the following method according to different attraction percentages.
(1) When the attraction percentage is 12%
The outlet air temperature is (300 × 13+300 × 0.12 × 27)/(300+300 × 0.12) ═ 14.5 deg.c
At the moment, the radiation induced air outlet system is a gear for rapid refrigeration and heating
(2) When the attraction percentage is 50%
Air outlet temperature (300 × 13+300 × 0.5 × 27)/(300+300 × 0.5) ═ 17.7 deg.c
