Detailed description of the invention
First see accompanying drawing 1-5, the new blower fan of Total heat exchange of the present utility model comprises new wind blower fan and (is preferably centrifugal blower, as shown in FIG.) 1, exhaust fan (is preferably centrifugal blower, as shown in FIG.) 2 and Total heat exchange core body 3, wherein, new wind blower fan 1 and exhaust fan 2 be arranged to be positioned at Total heat exchange core body 3 both sides and on the extended line being positioned at the different current paths of Total heat exchange core body 3 (such as, each blower fan is placed on Total heat exchange core body both sides in the horizontal direction and in the extended line of different current path), and described new wind blower fan 1 is vertical with the length direction of described Total heat exchange core body 3 with the fan blade axis of described exhaust fan 2.For Total heat exchange core body, its length direction refers to and forms the stacking direction of each switching layer of this Total heat exchange core body., namely, on the length direction of Total heat exchange core body, in Total heat exchange core body, there is not any air flow channel yet.Fan blade axis is vertical with the length direction of Total heat exchange core body, comprise the situation of fan blade axis perpendicular to new assembling face (back side), also comprise the situation that fan blade axis and new assembling face exist certain inclination angle, such as fan blade axis can deflection certain angle in figure paper in Figure 5.
Because the fan blade axis of each blower fan is vertical with the length direction of Total heat exchange core body, the fan blade diameter of blower fan is no longer limited to body thickness; Equally, because the axial dimension of blower fan is very little, thus the thickness of body also can arrange less.In order to the further reduction of adaline body thickness, Total heat exchange core body can adopt the shape (as shown in Figure 4) of flat six prisms, compared with quadrangular shape conventional in prior art, its gauge taken is less, but does not therefore reduce for the length of the gas channel of Total heat exchange.
In above-mentioned arrangement, Total heat exchange core body 3 is positioned in the middle of fuselage, and two Fans 1 and 2 are placed in Total heat exchange core body 3 left and right sides respectively.Preferably, fuselage interior is separated by dividing plate in the horizontal direction and forms 4 air chambers.
The cardinal principle of the new blower fan of Total heat exchange of this preferred embodiment is: after switching on power, outdoor new wind is by the air chamber 10 in the ingress engine of air port 6, under the suction of new wind blower fan 1, enter air chamber 11 by Total heat exchange core body 3, then send into indoor by new wind blower fan 1 through air port 7; Indoor exhaust wind then by the air chamber 12 in the ingress engine of air port 8, enters air chamber 13 by Total heat exchange core body 3, then sends outdoor by air draft centrifugal blower 2 through air port 9 under the suction of exhaust fan 2.By the flowing of the new wind in outdoor from the different runners of indoor exhaust wind in Total heat exchange core body 3, owing to there is temperature and psychrometric difference in outdoor new wind and indoor exhaust wind, so complete the exchange of temperature and humidity in Total heat exchange core body 3, improve temperature and the water capacity of new wind in the winter time, temperature and the water capacity of new wind is reduced in summer, while fresh air is provided, reduces the impact of new wind on indoor environment (temperature, humidity), reduces the energy loss of air-conditioning equipment.
Different from the modes of emplacement of blower fan on rear side of Total heat exchange core body that the new blower fan of Total heat exchange similar in prior art adopts, in the utility model, (such as arrange with the orientation shown in Fig. 6 when the new horizontal fan of Total heat exchange is placed, the rear of the arrow points body in figure), each centrifugal blower is placed on the both sides of Total heat exchange core body 3 in horizontal positioned mode (the fan blade axis of centrifugal blower is perpendicular to the ground), fan blade axis is at Total heat exchange core body border A, within the scope of B (see Fig. 8), each blower fan is in the side (see Fig. 7) of the centering face H-H of Total heat exchange core body 3 simultaneously, form double-suction type structure.Adopt this modes of emplacement can reduce machine internal resistance, meet the outer high static pressure operating mode of machine.The putting position of each blower fan is not higher than the end face T (see Fig. 7) of Total heat exchange core body simultaneously, can make by the air-flow of core body more even, thus improve exchange efficiency.Adopt the new blower fan of the Total heat exchange of preferred embodiment of the present utility model that the decrease of fuselage thickness can be made to reach 32%, make the decrease of fuselage width size reach 24%, thus be especially beneficial to and install in family expenses furred ceiling.
As another preferred embodiment, the new blower fan of Total heat exchange of the present utility model can also comprise two bypass air-exchanging structure, described Total heat exchange core body is not all flowed through to make outdoor new wind and indoor exhaust wind, or comprise single bypass air-exchanging structure, do not flow through described Total heat exchange core body to make outdoor new one of wind and indoor exhaust wind.The meaning that bypass air-exchanging structure exists such as is, in the season (such as spring, autumn) of not using air-condition, particularly in the season that outside air temperature is more comfortable, and can the outer new Total heat exchange between wind and indoor exhaust wind of screened room.
Such as, described pair of bypass air-exchanging structure or described single bypass air-exchanging structure are arranged on the end of described Total heat exchange core body 3, and also, it is superimposed upon on the new blower fan of Total heat exchange on fuselage width direction.Preferably, described pair of bypass air-exchanging structure or described single bypass air-exchanging structure comprise air-valve 5 and bypass passageways 4, and wherein said air-valve 5 is for cutting out and open air inlet or the air outlet of described bypass passageways 4.Preferably, the air inlet of bypass passageways and air outlet are be opened in the opening on the sidewall between bypass passageways from different air chamber, and air-valve 5 is arranged on this opening part.Certainly, air-valve 5 also can be arranged on other position any in bypass passageways, as long as can guarantee reliably to close bypass passageways.
Specifically see Fig. 9-Figure 12, for two bypass air-exchanging structure, it mainly comprises: air-valve 5, two bypass passageways 4 (specifically comprising new wind bypass passageways 14, air draft bypass passageways 15), bypass air inlet 16,17, bypass air outlet 18,19.When bypass ventilatory is closed, air-valve 5 closedly makes bypass air inlet 16, bypass air outlet 18 closes (Fig. 9, Figure 10), air in each air chamber cannot enter another air chamber by bypass passageways, and can only be entered another air chamber by the gas channel in Total heat exchange core body; When bypass function is opened, air-valve 5 is opened (Figure 11, Figure 12), new wind bypass passageways 14 is entered through bypass air inlet 16 after outdoor new wind enters air chamber 10, and enter air chamber 11 by bypass air outlet 19, indoor are sent into through air port 7 again by new wind centrifugal blower 1, like this, outdoor new wind is no longer by Total heat exchange core body 3; Simultaneously, indoor exhaust wind enters air draft bypass passageways 15 through bypass air inlet 17 after entering air chamber 12 by air port 8, and enters air chamber 13 by bypass air outlet 18, then sends outdoor by air draft centrifugal blower 2 through air port 9, like this, indoor exhaust wind is also no longer by Total heat exchange core body 3.
For suitably reducing fuselage width size, also single by-pass structure can be adopted, also be, make wherein a road air-flow not by Total heat exchange core body 3 another road still by Total heat exchange core body 3, like this, the width of fuselage can obtain reduction to a certain extent, and the amount of reduction such as approximates bypass passageways size in the direction of the width.
In the new blower fan of Total heat exchange of the present utility model, between the spiral case both sides of new wind centrifugal blower 1 or air draft centrifugal blower 2 and the sidewall of the new blower fan of Total heat exchange and midfeather (i.e. the two side of air chamber), be provided with gap b, c (see Fig. 2).According to the utility model, after the placing height of blower fan is fixing, the value of spiral case and both sides clearance distance b, c has an impact for machine inner structure resistance, thus there is impact to new fan delivery and exchange efficiency.Because if any one is too small for gap b, c, air-supply all may be caused smooth, and when this gap b, c are all increased to more than certain numerical value, can decline to a great extent to wind quantitative limitation.Table 1 shows gap b, c affects measured data (with a air quantity for 250m to air quantity and exchange efficiency
3the new blower fan of heat exchange type of/h is testing machine, its fuselage thickness 220mm, fan blade diameter 265mm).
Table 1: under different b, c value, the test data of air quantity and exchange efficiency
Data from table 1 can be clear that, along with the size of gap b constantly increases, in the process of the corresponding reduction of gap c, air quantity presents the trend of first increases and then decreases, when also can find out that the span of gap b and c ratio μ is 0.84 < μ < 1.4, air quantity changes less, when μ value is selected between preferred scope 1≤μ < 1.4, there is peak in the air quantity of the new blower fan of heat exchange; Now heat exchanger effectiveness variation tendency is identical with the change of air quantity, reaches maximum when air quantity is minimum.
Therefore, ratio μ meets: 0.84≤μ < 1.4; Preferably 1≤μ < 1.4.
In addition, in the new blower fan of Total heat exchange of the present utility model, as shown in Figure 8, blower fan axis is within the scope of Total heat exchange core body border A, B, and the distance a of blower fan axis and outer boundaries B exists complete machine air quantity and enthalpy exchange efficiency to be affected.Table 2 show distance a on air quantity and exchange efficiency affect measured data (with the new blower fan of same a heat exchange type that adopts in table 1 for testing machine).
Table 2: under different a distance, the test data of air quantity and exchange efficiency
Test result as can be seen from table 2, in the process that a value increases gradually, air quantity and heat exchanger effectiveness present the phenomenon of first increases and then decreases simultaneously, and when can find out that a value is in 1/3≤φ≤1 with the span exchanging core body lenth ratio φ, air quantity change is less simultaneously; When the value of φ selects preferred scope 0.5≤φ≤5/6, there is maximum in air quantity and heat exchanger effectiveness, can find out that the amplitude that exchange efficiency changes is greater than air quantity amplitude, so should determine φ value according to heat exchanger effectiveness value.
Therefore, ratio psi meets: 1/3≤φ≤1; Preferably 0.5≤φ≤5/6.
Again in addition, in the new blower fan of Total heat exchange of the present utility model, on rear side of the spiral case of new wind centrifugal blower 1 or air draft centrifugal blower 2 and between Total heat exchange core body 3, there is distance d.According to the utility model, the value of distance d has an impact for machine inner structure resistance, thus there is impact to new fan delivery and exchange efficiency.Because this apart from too small make air-flow pass through exchange core body uneven, enthalpy exchange efficiency can be caused to reduce; And this distance can make uniform stream by Total heat exchange core body when certain limit strengthens, improve exchange efficiency; When this distance is increased to a certain degree, the impact of this distance reduces.Table 3 show distance d on air quantity and exchange efficiency affect measured data (with the new blower fan of same a heat exchange type that adopts in table 1 for testing machine).
Table 3: under different d distance, the test data of air quantity and exchange efficiency
As can be seen from the data of table 3, in the process that the value of distance d constantly increases, air quantity and heat exchanger effectiveness all present the trend of increase, and the variable quantity increased has trend from large to small.Also can find out that the air quantity change when-20 ~ 10mm of the span of distance d is less, heat exchanger effectiveness is higher, when d value selects preferred scope-10 ~ 5mm air quantity and exchange efficiency higher, as d > 5mm, air quantity and exchange efficiency there is no larger change.Also namely, along with the further increase of this size, the contribution for the lifting of air quantity and exchange efficiency is not obvious, but comparatively obvious on the impact of cabinet size, thus continues to increase unhelpful.
Therefore, distance d within the scope of-20 ~ 10mm, preferably within the scope of-10 ~ 5mm.
Preferably, the air quantity of the air quantity of new wind centrifugal blower 1 can be arranged to be greater than (preferably slightly larger than) exhaust fan 2, can ensure that indoor do not occur negative pressure like this.When new wind centrifugal blower 1 and air draft centrifugal blower 2 form Dual-motors Driving, such as can by new wind screen pack, air draft screen pack be arranged to resistance difference, the differentiation that can also realize new wind centrifugal blower 1 and air draft centrifugal blower 2 actual air volume size controls, thus realize new wind air quantity slightly larger than air draft air quantity
Preferably, the new blower fan of Total heat exchange of the present utility model can arrange multiple air port (as shown in Figure 1) at the two ends in fuselage length direction, or also in the both sides in fuselage width direction, multiple air port can be set (such as, as shown in figure 13, air port is set at C, D, E, F place).Like this, such as, when installing space is limited, can select neatly according to actual conditions.
Preferably, when the new horizontal fan of described Total heat exchange is placed (such as can see Fig. 4), the placement direction of Total heat exchange core body 3 is horizontal direction, also be, the stacking direction forming each switching layer of Total heat exchange core body carries out stacking in the horizontal direction, like this, the thickness of body can not by the restriction of Total heat exchange core body stack height size.In this case, Total heat exchange core body stack height size impact to be the width of body.
