As Figure 1-Figure 2, the ducting assembly 1 of airhandling equipment 100 according to an embodiment of the present invention, comprising: foam Air duct part 11, filter device 12 and heat exchanging core 13.
As shown in figure 5, indoor return air mouth 11a, indoor air outlet (not shown go out), room can be equipped on foam air duct part 11 Outer fresh wind port 11b and outdoor exhaust outlet can be equipped with return air flow path 11d and air inlet flow path 11c, return in foam air duct part 11 Road 11d may include interconnected return air inlet air duct 11f and return ventilating duct (not shown go out), return air inlet air duct The arrival end of 11f can be equipped with indoor return air mouth 11a, and the outlet end of return ventilating duct can be equipped with outdoor exhaust outlet, air inlet Flow path 11c may include interconnected air inlet inlet conduits 11e and air intake ventilating duct, enter the wind the entrance of inlet conduits 11e End can be equipped with outdoor fresh air mouth 11b, and the outlet end of air intake ventilating duct can be equipped with indoor air outlet.
Specifically, outdoor fresh air air-flow can be entered by outdoor fresh air mouth 11b in air inlet flow path 11c, fresh air Air-flow can successively circulate in air inlet inlet conduits 11e and air intake ventilating duct, and fresh air air-flow can pass through indoor air outlet It enters in the interior space.Indoor air draught can be entered in return air flow path 11d by indoor return air mouth 11a, indoor Air draught can successively circulate in return air inlet air duct 11f and return ventilating duct, then indoor air draught can To be drained into the exterior space by outdoor exhaust outlet.Room air and outdoor air can pass through foam air duct part 11 as a result, Interior air inlet flow path 11c and return air flow path 11d carries out circulation, can play the role of promoting indoor air freshness.
As shown in Fig. 5 and Figure 13, filter device 12 can be located in air inlet flow path 11c to be filtered to fresh air air-flow. Wherein, filter device 12 can be sponge, filter device 12 or HEPA net.Filter device 12 can will be in fresh air air-flow The contaminant filters such as dust, PM2.5 fall, it is possible thereby to promote the cleannes of fresh air air-flow, and then the use of user can be promoted Experience.
Heat exchanging core 13 can be connected to air inlet flow path 11c and return air flow path 11d respectively, enter the wind flow path 11c and return air Air draught in flow path 11d can exchange heat in heat exchanging core 13, in the airflow direction of return air flow path 11d On, return air inlet air duct 11f can be located at the upstream of heat exchanging core 13, on the airflow direction of air inlet flow path 11c, into Wind inlet conduits 11e can be located at the upstream of heat exchanging core 13.
It is set specifically, air inlet flow path 11c and return air flow path 11d can intersect along the diagonal of foam air duct part 11 It sets.Wherein, heat exchanging core 13 can be for as heat transferring medium, the fresh air air-flow entered the wind in flow path 11c can pass through heat exchange Core 13 exchanges heat with the room air air-flow in return air flow path 11d.As a result, by above-mentioned setting, indoor temperature can be made Degree keeps relative equilibrium, can prevent outdoor fresh air air-flow from entering directly into the interior space and influencing indoor average temperature Degree, so as to promote the usage comfort of user.
For example, the temperature of fresh air air-flow is lower when outdoor temperature is lower, the temperature of indoor air draught is higher.Newly General mood stream can be exchanged heat by the room air air-flow in heat exchanging core 13 and return air flow path 11d to promote its own Temperature thus it can be prevented that fresh air air-flow enters in the interior space and indoor mean temperature is caused to reduce.Work as outdoor temperature When higher, the temperature of fresh air air-flow is higher, and the temperature of indoor air draught is lower.Fresh air air-flow can pass through heat exchanging core 13 exchange heat with the room air air-flow in return air flow path 11d to reduce the temperature of its own, thus it can be prevented that new general mood It flows into the interior space and indoor mean temperature is caused to increase, the usage comfort of user can be promoted.
As shown in Fig. 2, in the vertical direction, the development length for entering the wind the arrival end of inlet conduits 11e can be H, air inlet The development length of the outlet end of inlet conduits 11e can be h, and the development length of the arrival end of return air inlet air duct 11f can be D, the development length of the outlet end of return air inlet air duct 11f can be d, and air inlet inlet conduits 11e and return air inlet air duct 11f can To meet relational expression: 0.3≤h/H≤0.7 and/or 0.3≤d/D≤0.7.That is, foam air duct part 11 can only meet Relational expression: 0.3≤h/H≤0.7, foam air duct part 11 can also only meet relational expression: 0.3≤d/D≤0.7, foam air duct part 11 can also meet relational expression: 0.3≤h/H≤0.7 and 0.3≤d/D≤0.7 simultaneously, as a result, by above-mentioned setting, can drop Circulating resistance of the low air draught in air inlet inlet conduits 11e and return air inlet air duct 11f, can increase foam air duct part 11 Fresh air air output and indoor wind air output.
Specifically, when the value of h/H is too small, if the development length h of the outlet end of air inlet inlet conduits 11e is kept not Become, then the development length H for entering the wind the arrival end of inlet conduits 11e becomes larger, although thus can increase air inlet inlet conduits 11e's Intake, but enter the wind the excessive normal assembly that will affect foam air duct part 11 of opening of the arrival end of inlet conduits 11e.If into The development length H of the input end of wind inlet conduits 11e is constant, then the development length h for entering the wind the outlet end of inlet conduits 11e becomes Small, the draught area for entering the wind the outlet end of inlet conduits 11e becomes smaller, and thus will increase the new general mood in air inlet inlet conduits 11e The circulating resistance of stream, and then will increase the noise of the generation of foam air duct part 11.
When the value of h/H is too big, if the development length h of the outlet end of air inlet inlet conduits 11e is constant, entrance is entered the wind The development length H of the arrival end of air duct 11e becomes smaller, and thus will increase the circulation resistance of the fresh air air-flow in air inlet inlet conduits 11e Power reduces the fresh air intake of air inlet inlet conduits 11e.If the development length H for entering the wind the input end of inlet conduits 11e is constant, The development length h for then entering the wind the outlet end of inlet conduits 11e becomes larger, thus will increase air inlet inlet conduits 11e outlet end with Contact area between heat exchanging core 13, the fresh air air-flow of air inlet inlet conduits 11e outflow and the interior outflow of heat exchanging core 13 Room air gas stream make impact, thus will affect the normal circulation of the air draught in foam air duct part 11.
It is verified through inventor's test of many times, as 0.3≤h/H≤0.7, foam air duct part 11 both can satisfy assembly and need Ask, and the circulating resistance for entering the wind fresh air air-flow in inlet conduits 11e is smaller, the fresh air air output of foam air duct part 11 compared with Greatly, and then the air change efficiency between indoor and outdoor can be promoted.
Similarly, it when the value of d/D is too small, if the development length d of the outlet end of return air inlet air duct 11f is constant, returns The development length D of the arrival end of wind inlet conduits 11f becomes larger, although the intake of return air inlet air duct 11f thus can be increased, But the excessive normal assembly that will affect foam air duct part 11 of opening of the arrival end of return air inlet air duct 11f.If return air inlet The development length D of the input end of air duct 11f is constant, then the development length d of the outlet end of return air inlet air duct 11f becomes smaller, return air The draught area of the outlet end of inlet conduits 11f becomes smaller, and thus will increase the room air air-flow in the 11f of return air inlet air duct Circulating resistance also will increase the noise of the generation of foam air duct part 11.
When the value of d/D is too big, if the development length d of the outlet end of return air inlet air duct 11f is constant, return air inlet The development length D of the arrival end of air duct 11f becomes smaller, and thus will increase the stream of the room air air-flow in the 11f of return air inlet air duct Logical resistance, reduces the intake of the room air air-flow of return air inlet air duct 11f.If the input end of return air inlet air duct 11f Development length D is constant, then the development length d of the outlet end of return air inlet air duct 11f becomes larger, to will increase return air inlet air duct Contact area between the outlet end and heat exchanging core 13 of 11f, the room air air-flow and heat of return air inlet air duct 11f outflow The fresh air air-flow flowed out in exchange core 13 can collide, and thus will affect the normal of the air draught in foam air duct part 11 Circulation.
It is verified through inventor's test of many times, as 0.3≤d/D≤0.7, foam air duct part 11 both can satisfy assembly and need It asks, and the circulating resistance of the room air air-flow in the 11f of return air inlet air duct is smaller, the room air gas of foam air duct part 11 The air output of stream is larger, and then can promote the air change efficiency between indoor and outdoor.
The ducting assembly 1 of airhandling equipment 100 according to an embodiment of the present invention enters the wind inlet conduits 11e by setting Meet relational expression with return air inlet air duct 11f: 0.3≤h/H≤0.7 and/or 0.3≤d/D≤0.7 can reduce air draught Circulating resistance in foam air duct part 11, can increase the air quantity of foam air duct part 11, so can be promoted room air with Air change efficiency between outdoor air.
According to some embodiments of the present invention, air inlet inlet conduits 11e can be with further satisfaction: h/H=0.5 is entered the wind The outlet end of inlet conduits 11e extend in vertical direction length be enter the wind inlet conduits 11e arrival end in the vertical direction Development length half, thus can not only reduce circulating resistance of the fresh air air-flow in air inlet inlet conduits 11e, promoted it is new Wind air output can also reduce the work noise of ducting assembly 1.
According to some embodiments of the present invention, air inlet inlet conduits 11e can be with further satisfaction: d/D=0.5, i.e. return air The outlet end of inlet conduits 11f extend in vertical direction length be return air inlet air duct 11f arrival end in the vertical direction Development length half, thus can not only reduce circulating resistance of the room air air-flow in the 11f of return air inlet air duct, mention The return air amount for rising room air, can also reduce the work noise of ducting assembly 1.
As shown in figure 5, according to some embodiments of the present invention, in foam air duct, the length direction of part 11 is (as shown in Figure 5 Left and right directions) on, the development length for entering the wind the outlet end of inlet conduits 11e can be B1, the outlet end of return air inlet air duct 11f Development length can be B2, entering the wind inlet conduits 11e and return air inlet air duct 11f can satisfy relational expression: B1> B2.It needs It is illustrated, the width direction (front-rear direction as shown in Figure 5) of foam air duct part 11 can be for from interior to outdoor The length direction in direction, foam air duct part 11 is vertical with the width direction of foam air duct part 11.
It is understood that filter device 12 can be to air inlet flow path since filter device 12 is located in air inlet flow path 11c Fresh air air-flow in 11c is filtered, and thereby increases the circulating resistance of the fresh air air-flow in air inlet flow path 11c.Pass through setting B1> B2, the air-flow outflux that the air stream outlet in inlet conduits 11e is greater than in the 11f of return air inlet air duct is entered the wind, it is possible thereby to drop The circulating resistance of fresh air air-flow in low air inlet flow path 11c, so that it is guaranteed that the air in air inlet flow path 11c and return air flow path 11d The flow of air-flow generally remains balance, and the operation of airhandling equipment 100 can be made more smooth, and then can reduce air gas Flow the noise generated when circulating in foam air duct part 11.
In Fig. 1 and specific example shown in fig. 5, ducting assembly 1 can also include air intake blower fan 14 and return air fan 15. Wherein, the air inlet of air intake blower fan 14 is connected with the indoor air outlet of air inlet flow path 11c, the exhaust outlet of air intake blower fan 14 and room Interior space is connected.When air intake blower fan 14 works, air intake blower fan 14 can be formed in air inlet flow path 11c negative by rotating Pressure.Under the action of negative pressure, outdoor fresh air air-flow can be entered in air inlet flow path 11c and be carried out in air inlet flow path 11c Circulation, fresh air air-flow can be completed to filter and be exchanged heat when entering the wind and circulating in flow path 11c, may then pass through air intake blower fan 14 Exhaust outlet enters in the interior space.
The air inlet of return air fan 15 is connected with the outdoor exhaust outlet of return air flow path 11d, the exhaust outlet of return air fan 15 It is connected with the exterior space.When return air fan 15 works, return air fan 15 can be by rotating with the shape in return air flow path 11d At negative pressure, under the action of negative pressure, indoor air draught can be entered in return air flow path 11d and in return air flow path 11d It circulates, can complete to exchange heat with fresh air air-flow when indoor air draught circulates in return air flow path 11d, then can lead to The exhaust outlet for crossing return air fan 15 enters in the exterior space.
Wherein, the development length B of the outlet end of inlet conduits 11e is entered the wind1Outlet end greater than return air inlet air duct 11f Development length B2, the circulating resistance that can reduce air inlet flow path 11c can so as to reduce the workload of air intake blower fan 14 So that air intake blower fan 14 and return air fan 15 generally remain synchronized rotation, air intake blower fan 14 and return air wind thus can be not only reduced The work noise that machine 15 generates can also increase the air output of air inlet flow path 11c, can promote the sky of airhandling equipment 100 Gas disposal efficiency.
