The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment summary of the invention of the present invention is done further to set forth.Hereinafter, will be defined as new wind, will be defined as return air from the outdoor air of indoor discharge from the air in the outdoor inlet chamber.
The invention provides the heat exchange type ventilator (hereinafter referred air interchanger) of the compact of a kind of Bao Youxiao again as shown in Figure 1.
Can know that in conjunction with Fig. 1 to Fig. 3 this air interchanger has the casing 1 of cuboid, casing 1 is made up of sidewall 10, top board 10A and base plate 10B.During installation, top board 10A presses close to the roof ceiling, and base plate 10B contacts with furred ceiling.Sidewall 10 is equated by four tile heights and mutually perpendicular sidewall paneling is formed, the long limit of two sidewall panelings that are parallel to each other 101 and 102 composition cuboids wherein, the minor face of other two sidewall panelings that are parallel to each other 103 and 104 composition cuboids.The corresponding sidewall paneling of limit and minor face be will grow and long side plate and minor face plate will be defined as respectively.The height of sidewall 10 is the same basically with the height of heat exchanger 20 (seeing below).
Inner at this air interchanger, heat exchanger 20 is installed.The cross section of the horizontal direction of this heat exchanger 20 is a square, and extends along the short transverse of sidewall 10.This heat exchanger 20 adopts the distributary heat-exchangers of the plate type, has the square fin of multilayer that is arranged in parallel along sidewall 10 short transverses.Between adjacent fins, form isolated each other air-guiding aisle, adjacent air-guiding aisle is vertical each other also isolates, and each air-guiding aisle replaces on the short transverse of heat exchanger 20 successively.Heat exchanger 20 has new wind air inlet and return air air inlet, with the new wind air outlet of new wind air inlet perforation and the return air air outlet that connects with the return air air inlet.New wind air inlet and new wind air outlet are arranged on the relative both sides of text tee section; Return air air inlet and return air air outlet are arranged on the relative other both sides of text tee section.
Two adjacent settings of air inlet of heat exchanger 20, and two air inlets are placed with respect to same block of minor face plate (sidewall paneling 103 among Fig. 1) and with this minor face plate angled (for example 45 degree) simultaneously.Resistance when getting into heat exchanger 20 in order to reduce new wind and return air; Is good with the diagonal between two air inlets in this heat exchanger 20 when vertical with this minor face plate (sidewall paneling 103), is 45 ° of placements with the angle between air inlet plane and the long side plate in the present embodiment.
Among Fig. 1, therefore the return air air inlet of heat exchanger 20, offers return air inlet 13 towards the left side (indoor) on the long side plate 101 in this air interchanger left side, correspondingly, on the long side plate 102 on this air interchanger right side (outside), offer exhaust outlet 12.In like manner, therefore the new wind air inlet of heat exchanger 20, offers fresh wind port 14 on the top of long side plate 102 towards the right side, correspondingly, on long side plate 101, offers air outlet 11.Wherein, 14 one-tenth diagonal settings of air outlet 11 and fresh wind port, 12 one-tenth diagonal settings of return air inlet 13 and exhaust outlet.
In this embodiment, the level cross-sectionn of this heat exchanger 20 is a square, and the Diagonal Dimension of heat exchanger 20 is less than or equal to the minor face size of housing 1 level cross-sectionn.In this vertical view, cornerwise two ends of heat exchanger 20 are connected with two long side plates of housing 1 respectively, and another cornerwise two ends are connected with two minor face plates of housing 1 respectively.In order to reduce the volume of this air interchanger, a cornerwise end that is connected with minor face can with the direct butt of minor face plate, between another minor face plate of the other end and housing distance is arranged, and connects through the air channel plate.Thus the enclosure interior spatial is divided into four spaces that are connected with air outlet 11, fresh wind port 14, return air inlet 13 and exhaust outlet 12 respectively.
Specifically with reference to figure 1 and Fig. 3; The last linea angulata of the heat exchanger 3 of this cubic shaped is connected through windward guidance tape 15 with the minor face plate 103 of sidewall; Following linea angulata is connected through leeward guidance tape 16 with another minor face plate 104 of sidewall; The left comer line is connected through left air channel plate 17 with the long side plate 101 of the sidewall that is positioned at the left side, and the right corner line is connected through right air channel plate 18 with the long side plate 102 that is positioned at the right side of sidewall.In the present embodiment; The size of windward guidance tape 15 is less than the size of leeward guidance tape 16; Left side air channel plate 17 is measure-alike with right air channel plate 18, and therefore new wind gets into the space and sends into the identical size in space with return air, but the two all sends into the size in space and return air discharge space less than new wind.
Wherein, air channel plate 15, air channel plate 16 and heat exchanger 20 together, the space that sidewall 10 is surrounded is divided into two, the space in heat exchanger 20 left sides is the space, indoor, the space on heat exchanger 20 right sides is the space, outside.Air channel plate 17 further is divided into four independently spaces with the space, indoor that air channel plate 18 will be positioned at heat exchanger 20 left sides again respectively with the space, outside that is positioned at the right side.The return air of being made up of long side plate 101, minor face plate 103, air channel plate 15, air channel plate 17 and heat exchanger 20 that is positioned at heat exchanger 20 upper left sides gets into the space; The new wind that is positioned at heat exchanger 20 left downsides by long side plate 101, minor face plate 104, air channel plate 16, air channel plate 17 and heat exchanger 20 are formed is sent into the space; The new wind of being made up of long side plate 102, minor face plate 103, air channel plate 15, air channel plate 18 and heat exchanger 20 that is positioned at heat exchanger 20 upper right sides gets into the space; Discharge the space with the return air of forming by long side plate 102, minor face plate 104, air channel plate 16, air channel plate 18 and heat exchanger 20 that is positioned at heat exchanger 20 lower right sides.New wind send into space, return air discharge space, return air get into space and new wind get into the space respectively with long side plate on air outlet 11, exhaust outlet 12, return air inlet 13 and the fresh wind port 14 offered corresponding.And new wind entering space and new wind are sent into the space and are connected the new wind passage of formation through heat exchanger 20, and return air entering space and return air are discharged the space and connected the formation return air channel through heat exchanger 20, and newly wind and return air carry out heat exchange in these heat exchanger 20 inside.
As shown in Figure 1, send into space and return air at adjacent new wind and discharge pressure fan 21 and exhaust blower 25 are installed in the space, be used for air is sucked air interchanger inside, form the circulation of air in return air channel and the new wind passage.Pressure fan 21 and exhaust blower 25 are located at the space of the correspondence of heat exchanger 20 air-out oral-laterals, the influence the when resistance of having eliminated blower fan gets into heat exchanger 20 to cold and hot air, thus reduced the influence of blower fan to heat exchanger effectiveness.
Can be clear that by Fig. 1; Pressure fan 21 is arranged on new wind and sends into the space; Exhaust blower 25 is arranged on return air and discharges the space, and these two spaces are arranged in the same side (downside of Fig. 1) of heat exchanger, and divides and be in indoor (left side among Fig. 1) and outside (right side among Fig. 1).Pressure fan 21 is not arranged on the diagonal of heat exchanger with exhaust blower 25, and like this, the air channel of new wind and return air is formed on the diagonal of heat exchanger, has improved heat exchanger effectiveness and heat exchanger time.In addition, because pressure fan 21 and exhaust blower 25 are the be placed in indoor and the outside of heat exchanger, rather than overlapping setting, can reduce the height of air interchanger, make its attenuation.
The structure of pressure fan 21 and exhaust blower 25 is identical with drive principle, is example at this with exhaust blower 25, is explained.As shown in Figure 2, exhaust blower 25 is made up of wind wheel 251 and wind wheel volute 252, and the air in entering return air discharge space gets into wind wheel volute 252 simultaneously via the both sides up and down of exhaust blower 25, and under the effect of wind wheel 251, is discharged from outdoor.Wind wheel 251 is by motor 26 driven in rotation, and motor 26 is fixed on the top board 10A through electric machine support 27.
The height of exhaust blower 25 is less than the height of heat exchanger 20, and exhaust blower 25 is placed horizontally at return air and discharges the space, and is supported on the middle part of the return air air outlet place short transverse of heat exchanger 20 by installed part.That is, exhaust blower 25 is placed with the mode of the air-out direction that is axially perpendicular to heat exchanger 20 (horizontal direction) of wind wheel 251, and the direction of rotation of wind wheel 251 is parallel to heat exchanger 20.Pressure fan 21 is sent into the space to be arranged at new wind with exhaust blower 25 same modes.Thereby new wind and return air can get into the inside of wind wheel volute with symmetrical flow, and under the effect of wind wheel, from the outlet of blower fan air discharged from the both sides up and down of wind wheel volute after flowing out from heat exchanger 20 air outlets.On the one hand, because the height of pressure fan 21 and exhaust blower 25 less than the height of heat exchanger 20, makes the height of this air interchanger mainly determine that by the height of heat exchanger 20 blower fan itself is not extra to take height space, thereby has dwindled the height of this air interchanger; On the other hand, wind wheel volute 252 is supported in the middle part of heat exchanger 20 air outlet short transverses by electric machine support 27, makes air to get into wind wheel volute 252 respectively from the both sides up and down of wind wheel volute 252, has reduced the resistance at heat exchanger 20 air outlet places.
Extremely shown in Figure 8 in conjunction with Fig. 4; Carrying out the sketch map of heat exchange can find out from new wind passage, return air channel and new wind and return air: under the effect of pressure fan 21; Outdoor new wind gets into new wind from fresh wind port 14 and gets into the space, is admitted to indoor through heat exchanger 20 backs from air outlet 11; In like manner, under the effect of exhaust blower 25, indoor return air gets into return air from return air inlet 13 and gets into the space, discharges outdoor through heat exchanger 20 backs from exhaust outlet 12.Wherein, new wind and return air get into heat exchanger 20 (see figure 6)s with the mode of forthright from orthogonal both direction, and is after heat exchange is carried out in heat exchanger 20 inside, external with exhaust blower 25 these air interchangers of discharge through pressure fan 21.Among the figure, the direction of filled arrows indication is the flow direction of return air in the return air channel, and the direction of hollow arrow indication is the flow direction of new wind in the new wind passage.
In the present embodiment, the heat exchanger 20 of cubic shaped is the total-heat exchanger of being processed by paper material, is used to exchange the heat and the humidity of new wind and return air.Certainly, also the sensible heat exchanger of processing by metal material can be adopted here,, the heat of new wind and return air can be only be used to exchange like the sensible heat exchanger of processing by aluminium foil.The application of this heat exchanger belongs to the common practise in heat exchange field, is not described in detail in this.
In the prior art; The many modes with Qu Lu of the new wind of air interchanger and return air get into heat exchanger; Reduce the wind speed when air passes through heat exchanger, and could get into air-guiding aisle after making air need pass through certain drift, thereby caused the air-distribution in each air-guiding aisle uneven; Heat exchange area fails to be fully used, thereby has limited the raising of heat exchanger effectiveness.Slim heat exchange type ventilator provided by the present invention; Through air inlet on distributary heat-exchangers of the plate type air inlet and the casing over against mode; Make new wind and return air get into heat exchanger with the form of forthright; Keep original wind speed, made the effective heat exchange area of this heat exchanger to reach more than 95%.And this air interchanger combines pressure fan and exhaust blower are arranged on the air side right opposite of heat exchanger, has reduced the resistance at heat converter air-out mouth place, makes the heat exchange efficiency of this heat exchanger be improved.
This air interchanger is after air quantity is confirmed, the factor that influences heat exchanger effectiveness η has effective front face area S of heat exchanger 20, the wind speed v of heat exchanger, and the effective heat exchange area S ' of whole heat exchanger.In air interchanger shown in Figure 7, be a with the minor face of the air interchanger of this cuboid, long limit is b, highly is h, the length of side of the square section of heat exchanger 20 is L.
Then, effective front face area S=h * L (1) of heat exchanger
Wind speed v=Q/S=Q/ when air passes through heat exchanger (h * L)=(Q/h)/L (2)
This shows, under air quantity Q and heat exchanger 20 situation that highly h confirm, satisfy inverse proportion functional relation (indicating among Fig. 8) as shown in Figure 8 between wind speed v and the heat exchanger length of side L.
Because the heat exchanger effectiveness η of heat exchanger is relevant through the time t of heat exchanger with new wind or return air, when t was big more, heat exchanger effectiveness η was high more.And new wind or return air are satisfied through the time t of heat exchanger
t＝L/v （3）
When heat exchanger length of side L confirmed, wind speed v was with newly therefore wind or return air, satisfy inverse proportion function shown in Figure 8 through the inversely proportional function of time t of heat exchanger between wind speed v and heat exchanger effectiveness η.
With formula (2) substitution formula (3), obtain the heat exchanger time t of heat exchanger:
t＝L/v＝L/Q/S＝L/Q/(L×h)＝L
2×(h/Q) （4）
So when air quantity Q and heat exchanger height h confirmed, heat exchanger time was mainly by the length of side L decision of heat exchanger, and heat exchanger time t is the quadratic function of heat exchanger length of side L, and is as shown in Figure 9.Along with heat exchanger length of side L increases, the time lengthening of new wind and return air heat exchange in heat exchanger 20, heat exchanger effectiveness η increases.
On the other hand, the increase of heat exchanger length of side L can cause the increase of this air interchanger volume.If increase heat exchanger length of side L simply, can cause the excessive increase of this air interchanger volume, the concrete analysis process sees below.
As shown in Figure 7, the original length of side of heat exchanger is L, and the length on the long limit of the correspondence of this slim heat exchange type ventilator is b, and when the heat exchanger length of side increased Δ L, long limit increased length Δ b.With heat exchanger 20 air inlets and minor face plate holder angle is that 45 degree are example, is not more than the minor face a of slim heat exchange type ventilator at the heat exchanger diagonal, promptly during a >=1.4L; Increase the length of L; Minor face a does not increase, and long limit b increases length Δ b=1.4 Δ L, at this moment; This air interchanger volume increases Δ V=a * Δ b * h=1.4a * h * Δ L, and wherein h is the height of air interchanger.Because a, h fix, and satisfy linear relationship between Δ V and the Δ L.
And increase as heat exchanger length of side L, when causing a＜1.4L, Δ a=Δ b=1.4 Δ L,
ΔV＝(a×Δb＋b×Δa＋Δa×Δb)×h
＝1.96h×ΔL
2＋1.4(a＋b)h×ΔL
At this moment, the volume delta V of increase is the quadratic function of heat exchanger length of side value added Δ L.This shows,, should satisfy between the upper limit L1 of heat exchanger length of side L and the minor face a: a>=1.4L, i.e. L≤0.7a in order to realize the balance of volume and exchange efficiency.
In the present embodiment, confirm the Volume Changes value Δ V=a* Δ b*h=a*0.7* Δ L*h=0.7*a*h* Δ L of slim heat exchange type ventilator can obtain good product performance like this according to the product parameters of this enforcement.
In addition, machine internal resistance P satisfies following formula:
P＝0.6(Q/(0.29M?L))
2＝7.13(Q/ML)
2 （5）
Wherein, P is the machine internal resistance, and M is the distance (shown in Fig. 8 and 10) of the outlet air surface of wind wheel volute and heat exchanger, and L is the length of side of heat exchanger and satisfies L≤0.7a that Q is the air quantity through heat exchanger.Can know that by formula M reduces, P increases.And according to the characteristic of motor, resistance P increases, and then rotating speed can raise.And the power W=T*N/9.55 of complete machine, W is a complete machine power, and T is the moment of torsion of motor, and N is a motor speed, and visible rotating speed increases, and power W also can increase.
On the other hand, the M size is big more, and the crushing in the machine is just more little; Then the power of complete machine can reduce, can be energy-conservation to some extent aspect power consumption, but the appearance and size of while equipment can strengthen, volume can strengthen; So just lost the aim of miniaturization, and the use amount of material can increase along with the increase of M size, from the angle that economizes on resources; The volume of equipment can cause the use of resource to increase like this, so can not infinitely increase again.And when the M value was enough big, M continued to increase, and the P value changes also not obvious.
Like Fig. 5 and shown in Figure 8, the Volume Changes value Δ V of slim heat exchange type ventilator and the relation of M satisfy:
ΔV＝1.4Mab （6）
Wherein M is the distance of the outlet air surface of wind wheel volute and heat exchanger, and a and b represent the minor face and long limit of air interchanger respectively.
Can know according to formula 5 and formula 6, under the certain situation of Q (getting into the air quantity of heat exchanger), L (the heat exchanger length of side), a (the air interchanger minor face is long), b (the long length of side of air interchanger), resistance P (perhaps power W) and Δ V
2(perhaps M
2) be inversely proportional to, Δ V is directly proportional with M, needs the value of compromise power W and Δ V, under the power prerequisite suitable with the industry, makes volume as far as possible little, to realize the technique effect of the low-power consumption under small size, the miniaturization.
Resistance P (power W) is set in the level suitable with the industry, can obtains the minimum of a value of M value according to formula 5.The value of trying one's best policy setting M little according to volume again.The M value is 10～20mm in the present embodiment, is to be used to install the required size of heat exchanger, the i.e. minimum of a value of M value.In other words, though volume of the present invention has reduced, power consumption does not but increase, and is on close level in the industry.If in order to realize low-power consumption, and do not stress small size, can suitably increase the value of M.Among the present invention, the best value of M is 140mm, and this moment, the volume of air interchanger was a bit big, was suitable for the undemanding situation of the volume restrictions of air interchanger.
Second embodiment
As shown in Figure 9, the shape of the heat exchanger of second embodiment can be changed into hexagon, just can reduce the volume of equipment, and can be littler than the volume of the air interchanger of first embodiment.In this explanation and the first embodiment different portions.
Specifically as shown in Figure 9, hexagonal heat exchanger has and is positioned at the up and down minor face 35 of two positions, also has four long limits 36 that are connected respectively with minor face.Article two, be formed with the connecting plate 37 that connects heat exchanger and sidewall between the long limit.Be positioned at the long limit 36 of below, the minor face 35, connecting plate 37, sidewall 10 and the leeward guidance tape 16 that are positioned at the below isolated new wind and sent into space or return air discharge space, is used to hold pressure fan or exhaust blower.
Long limit 36 below being positioned at promptly near the long limit 36 of pressure fan or exhaust blower, and forms prominent angle to top the direction of pressure fan or exhaust blower (promptly away from) between the fillet 37, discharge the volume in space and increase thereby make new wind send into space or return air.In other words; Connecting plate 37 is not to be parallel to sidewall 10; But extend to the position intermediate that is positioned at fresh wind port and air outlet from position (junctions on two long limits 36) near fresh wind port, perhaps extend to the position intermediate that is positioned at return air inlet and exhaust outlet from position (junctions on two long limits 36) near return air inlet.Therefore, even be positioned at the center of air interchanger at heat exchanger 3, and under the identical situation of windward guidance tape 15 and leeward guidance tape 16, new wind is sent into the space and is also got into the space greater than new wind, and return air is discharged the space and also got into the space greater than return air.So, under the situation that the volume of heat exchanger itself does not increase, can have bigger space to hold pressure fan or exhaust blower.
Have at air interchanger under the situation of equal volume (casing is measure-alike), with this design, owing to the area of hexagonal area greater than square-section among first embodiment, so the heat-exchange time of heat exchanger is longer, heat exchange efficiency is higher.
With this design, can under the situation that reduces the heat exchanger overall volume, keep new wind to send into the big or small constant of space or return air discharge space.Therefore, if use heat exchanger, pressure fan, the exhaust blower identical with first instance, the volume of the heat exchanger of second embodiment can reduce, and the outlet air surface of wind wheel volute and heat exchanger can adjust to suitable size apart from M, with the reduction power consumption.
The 3rd embodiment
Shown in figure 10, the shape of the heat exchanger of the 3rd embodiment can be changed into four circular arcs, just can reduce the volume of equipment, and can be littler than the volume of the air interchanger of first embodiment.In this explanation and the first embodiment different portions.
Three straight flanges 39 that the heat exchanger 3 of present embodiment has four circular arc limits 38 and connects circular arc limit 38 and sidewall 10.The radius R on circular arc limit 38 is corresponding with the radius r of pressure fan or exhaust blower, and is suitable size, i.e. R=r+M with the outlet air surface that guarantees wind wheel volute and heat exchanger apart from M.
In the present embodiment, the circular arc limit 38 (i.e. circular arc limit between fresh wind port and return air inlet) that is arranged in Figure 10 top directly is connected with the sidewall 10 on top, does not promptly have straight flange 39.Certainly, as required, the sidewall 10 that straight flange 39 connects circular arc limit 38 with the top of top can be set also, new wind gets into the space and return air gets into the space to increase.Be appreciated that if exhaust blower and pressure fan are enough little, also can four circular arc limits 38 all be directly connected to sidewall 10, and omit straight flange 39.Also can be, just the circular arc limit 38 between pressure fan and exhaust blower be connected to sidewall through straight flange 39, and other three circular arc limits 38 are directly connected to sidewall 10.
Have at air interchanger under the situation of equal volume (casing is measure-alike); Design with this; Because the circular arc limit 38 of the heat exchanger among the 3rd embodiment and the area sum of straight flange 39 are greater than the area of the first embodiment square-section; So the heat-exchange time of heat exchanger is longer, heat exchange efficiency is higher.
Can under the situation that reduces the heat exchanger overall volume, keep new wind to send into the big or small constant of space or return air discharge space.Therefore; If use heat exchanger, pressure fan, the exhaust blower identical with first instance, the volume of the heat exchanger of the 3rd embodiment can reduce, and heat exchange efficiency is higher; And the outlet air surface of wind wheel volute and heat exchanger can adjust to suitable size apart from M, to reduce power consumption.
In the present invention; The exchange of cold and hot air is a chiasma type; The import of cold and hot air is arranged on the right opposite of type; And blower fan also is arranged on the right opposite of movement, and on structural design, has taken into full account the maximization of movement effective heat exchange area, and the movement effective heat exchange area can reach more than 95%.In addition, because pressure fan and exhaust blower are indoor and the outsides that splits in casing, can realize slimming among the present invention; Because the size of the appropriate design heat exchanger and the casing length of side, and the distance of appropriate design heat exchanger and fan scroll make air interchanger compacter, take the area of littler furred ceiling; Owing to adopt the heat exchanger of given shape and size; Under the prerequisite that does not increase the whole volume of air interchanger; Make the new wind that holds pressure fan and exhaust blower send into space and return air and discharge the space and increase, thereby realize the littler volume under the situation of identical heat exchanger effectiveness.
Above slim heat exchange type ventilator provided by the present invention has been carried out detailed explanation.As far as one of ordinary skill in the art, any conspicuous change of under the prerequisite that does not deviate from connotation of the present invention, it being done all will constitute to infringement of patent right of the present invention, with corresponding legal responsibilities.
