The specific embodiment
Fig. 1 has showed one embodiment of the present of invention, and equipment base 1 and these primary structures of carrying the integral air conditioner primary structure are all covered by casing 2.Outdoor dividing plate 6 is used for emission quotas and sucks the space separating, and outdoor use annular mouth 3 is as suction inlet.Emission quotas is the space that outdoor dividing plate 6 and outdoor heat converter 5 fence up, and is discharged into emission quotas from the air that is located at outdoor use annular mouth 3 downstream chamber's external fans 4.Dispose compressor 8, suction chamber 7 in the upstream of outdoor fan 4, also be useful on diaxon drive chamber external fan 4 and indoor fan 12 fan motors 11.Fan motor 11 is fixed on the equipment base 1 by fan motor brace table 10.When outdoor fan 4 rotations, from the space suction air of compressor 8, by being located at the outdoor heat converter 5 in outdoor fan 4 downstreams, to outdoor heat radiation.
In addition, in the indoor of interior external partition 9, be provided with front grid 19, filter 15 and indoor heat converter 21.Having will be from the air guide indoor fan 12 of indoor heat converter 21 and the suction casing 20 of indoor housing 17 parts of double as, also have from indoor annular mouth 13 suck air indoor fan 12, be used for the air from indoor fan is diverted to the projection 22 of equipment both sides, horizontal wind direction board 16 and vertical wind direction board 18 are installed in its downstream.
When indoor fan rotates, air is inhaled into by front grid 19, filter 15, after in indoor heat converter 21, absorbing heat, by be positioned at the fan downstream, be used for controlling blowing air flow to a plurality of projections 22 and indoor housing 17 shunt, cold air blows out to the indoor from the blow-off outlet 14 that is positioned at indoor heat converter 22 both sides.The pipeline that indoor heat converter 21 has the fin section of mainly carrying out heat exchange by portion in the central and flows through cold-producing medium constitutes, and its pipelines on two sides is made of the U-bend portion 23 that is bent.The width of fin portions is Wexf, and the width of fin portions and U-bend portion integral body is Wex.In integral air conditioner, from the air suction inlet inhaled air of indoor face side, Jie carries out heat exchange by the width W exf of the described fin section among the indoor heat converter 21 integral width Wex, and in the suction chamber internal fan 12.Then, the air after the mediation from indoor heat converter 21 both sides, the outlet 14 that is arranged on air suction inlet both sides, equipment front blows to indoor.
In addition, not shown, in the bottom of indoor heat converter 21, be provided with the dew receiver that receives condensate water and make water wherein be discharged to the canyon aqueduct of a side lower part outward.
As mentioned above, the pipe that connects airtight by fin, with fin of indoor heat converter and be that the U-bend that pipe is turned back back and forth constitutes at the fin two ends.Therefore, the fin section that two ends are clamped by U-bend is actual heat exchanging part, and the U-bend part at two ends is compared with fin section, is the part that is helpless to heat exchange basically.The width of most of integral air conditioner equipment is 470-660mm (according to differences of refrigerating capacity), and the width of indoor heat converter fin section is, the former is 270mm, and the latter is 375mm, and the ratio of actual heat exchanging part and plant width is about 0.57.
The integral width of indoor heat converter that comprises the U-bend of fin both sides is the length that adds the U-bend part of both sides on described fin portions partial width, and the former is 330mm, and the latter is about 435mm.(with the ratio of plant width be 0.7-0.66)
More than be to consider following problem and the size that determines, promptly, owing to want the real area of the front by making indoor heat converter to increase the requirement of guaranteeing heat exchange amount, and the floss hole of the words equipment both sides that increase on width of the frontal area of heat exchanger will narrow down, increase because air-out speed is anxious, the required pressure of fan rises and becomes big, and the result increases because of the fan input increases the consumes power that causes.
But this structure has following problem.Because the width of equipment was just smaller originally, if therefore the frontal area of indoor heat converter fin portions with respect to plant width less than described 0.57, if according to air quantity output for guaranteeing that the heat exchange amount is required, because the pressure loss of heat exchanger is big, just must use the fan (multi blade fan) of high pressure.Occur the high problem of fan noise like this, and then it is big the input of fan motor to occur, electricity consumption of equipment increases, the relatively poor such problem of COP.
Fig. 2 is the front view of present embodiment equipment, has shown with the width W u of equipment to compare the width W exf of heat exchanger, Wex, the relation of blow-off outlet width B d and device height direction.In the present embodiment, make the electric component 24 of equipment operation be located at the bottom of equipment, the width of equipment is Wu, and height is Hu, and the heat exchanger width is Wexf, Wex, highly is Hex, and blow-off outlet is that width is Bd, highly is the rectangle of Hd.
Therefore, need the characteristic of consideration fan to decide the pressure loss of heat exchanger and the balance of the blow-off outlet pressure loss (dynamic pressure of air-out).That is to say that increase if add ambassador's heat exchange amount by width W exf, the Wex that makes indoor heat converter 22, the air velocity that blows out from blow-off outlet 14 increases, its dynamic pressure increases sharply, and the pressure of fan must rise to higher pressure, otherwise air does not flow.
In addition, for the loss of the dynamic pressure that makes blow-off outlet and wind direction board reduces, the exit width Bd of blow-off outlet 14 is increased, the width of indoor heat converter 22 then reduces, and the pressure loss of heat exchanger increases, and simultaneously, generation can not be guaranteed the problem of heat exchange amount.
In addition, for guaranteeing air quantity, must improve the rotating speed of fan, this causes noise to increase considerably, and the input of fan motor surge, thereby power consumption is increased, and does not therefore have advantage from the saving concerned power.
That is to say, in integral air conditioner, between the width of the width W exf of indoor heat converter or Wex and blowing mouth, exist one to make the also maximum optimum value of the maximum heat exchange simultaneously of air quantity amount.
Fig. 3 is the figure of expression present embodiment effect, be existing value with the equipment noise, the occasion that changes with respect to plant width Wu at the width (Wex) of heat exchanger fin portion, air quantity changes, the figure illustrates the situation (the record value is at the situation more than the 1.5HP model, and making ability is definite value) that changes with the corresponding energy efficiency of capacity of equipment (being referred to as COP usually).Particularly, be by experimentizing and simulating the numerical value of derivation.The heat exchanger fin portion existing maximum of width is about Wexf/Wu=0.57, and the COP of this point is shown as COP=1.0.For fan, compare with multi blade fan, use the centrifugal fan (turbofan) of the absolute velocity little (the impeller outlet angle is about in the β 2=130) of impeller outlet.
This result shows, when the heat exchanger width is bigger than existing value, is Wexf/Wu=0.6 when above, and ability increases, and to 0.75 when above, ability sharply descends.Wexf/Wu is 0.75 when above, and the reason that ability sharply descends is, when Wexf/Wu became big, blowing mouth narrowed down relatively, and the speed of blowing increases, and the loss of dynamic pressure and wind direction board increases thus.For Wexf/Wu=1, get on very well in theory, because the area of blowing mouth is zero, air quantity is zero, so COP=0.
In addition, Wexf/Wu hour, the heat transfer area of heat exchanger is little, the pressure loss of heat exchanger is increased sharply, ability reduces, the input of fan motor increases obviously.When Wexf=0, air quantity is 0, so COP also is 0.
By above analysis as can be known, guarantee that existing C OP ratio is the condition more than 1, the ratio that is heat exchanger fin portion width (Wexf) and plant width (Wu) is in the scope of Wexf/Wu=0.60-0.75.
In air-conditioner, it is considerable more than 1% that COP is improved, and in addition, only is that the performance of fan and the installment state of heat exchanger just can make COP improve, and therefore the reason that does not allow price significantly rise is importantly saved electric power.This means that improving 1% preferable Wexf/Wu than existing COP is 0.625-0.7, is more preferably 0.65-0.7.
Above effect owing to just can obtain with the heat transfer area of heat exchanger and fan and the air quantity of noise weighing apparatus fan regularly, therefore can not cause expense to increase considerably, and in addition, also can make between development period and shorten.
Therefore, in integral air conditioner, the width W exf of heat exchanger fin portion and the ratio of plant width are during in the 0.60-0.75 scope or than described better scope, noise face and equipment cycle efficieny face also have the width (Bd) than existing blowing mouth just can dwindle, wind speed increases, thereby can expect to make cold air blast velocity to increase, cold wind can blow to whole indoor, obtains to help the effect of comfortableness.
As mentioned above, adopt present embodiment, in integral air conditioner, by making the relation between blowing mouth and the blowing mouth dynamic pressure reach best, can make the developed width that is defined the heat exchanger in the plant width increase more than 10% than prior art, high air quantityization in the time of can realizing equal noise increases indoor heat exchange amount, and uses small electric power.In addition, according to described result, can make the blowing mouth narrowed width, cold air blast velocity increases, and it is whole indoor that cold wind in time reaches, and the setting value of indoor temperature makes whole indoor temperature even in the time of reaching the operation beginning very soon.
Though above the prompting be the optimum value (Wexf) of heat exchanger fin portion width, for the heat exchanger of reality, as shown in Figure 1, the U-bend portion 23 that has pipeline in the both sides of fin portions, in this part, almost do not have the heat exchange effect, and in fact be necessary part.The width of blowing mouth (Bd) is also determined by the size that satisfies fin portions width (Wexf) and U-bend width (Bd).On described actual numerical value, because the width of this U-bend is the 22%-16% of fin portions width (Wexf), is the 13%-9% of plant width, therefore, the optimum value of heat exchanger integral width (Wex) is slightly higher than described optimum value, is Wex/Wu=0.7-0.85.That is to say, when the transverse axis of Fig. 3 is considered to the integral width of described heat exchanger, can thinks and to improve the width of heat exchange amount than being Wex/Wu=0.70-0.85 than prior art scope.
When comprising described U-bend, the optimum value of the heat exchanger integral width also optimum value with heat exchanger fin portion width (Wexf) is the same, exists to make the higher optimum range of energy consumption efficiency (COP).
As mentioned above,, can increase the wind speed of blowing mouth, also can shorten the time that reaches even distribution of indoor temperature and predetermined temperature if likening to of heat exchanger width and plant width is optimum range.Present embodiment is exactly the equipment that can further improve this effect.
Existing blowing mouth is positioned at the front of equipment, is the structure that previously blow out of cold air from equipment, to this, the structure that the modified example of blowing mouth shown in Figure 4 adopts is that it is positioned at the side of equipment, and blowing mouth 14 becomes big, along with the swing of wind direction board 18, cold wind blows out from the both sides of equipment.When making blowing mouth 14 become big in the equipment both sides, the wind speed of blowing mouth 14 slows down, and can ability be improved by further high air quantity.Usually, owing to make front escutcheon bending, the size (Dd) that preferably makes expansion is more than 20% of blowing mouth width (Bd).
Like this, can make indoor temperature distribution following effect occur.That is to say; the blowing mouth that is positioned at the equipment side is enlarged; utilize wind direction board; when cold air blows out to both sides; because blowing mouth is bigger than prior art, therefore reduced the loss of wind direction board, it is all indoor that cold air can be full of; wall is turned cold easily, can also occur the effect of radiation refrigeration usually.
Utilize Fig. 1 that the shape of indoor fan 12 is described below.As indoor fan 12, the external diameter of its core 26 (guard shield) is littler than the internal diameter of side plate 25 (wheel hub), and the external diameter of impeller 24 (blade) is reduced gradually from side plate 25 side direction cores 26 sides.Compare axially for definite value the time with the diameter of blade 24, the fan motor input can reduce more than 10%.If adopt the true form of described heat exchanger, also have the example of blowing mouth, efficiency of power dissipation shown in Figure 3 (COP) can further improve.
In addition, in described embodiment, though be that the integral air conditioner that has blowing mouth about indoor heat converter is described, but have a blowing mouth in other place also can reach this effect.
If adopt above embodiment, in the width of certain device, because the real area of heat exchanger is installed to greatest extent, so, under the certain situation of ability, can reduce the electric power that consumes, reach high air quantityization, improved the effect of refrigeration.And, owing to reduced the input of fan motor, thus have can realize that resource minimizes, reduction expense, light-weighted effect.
