发布时间: 2017年09月11日 | 次浏览 | 分享到:

1、什么是新风?

1, what is the new wind?

答:新风系统就是通过新风机组、新风管道和风口,将室外新鲜空气经过处理后送入室内,通过风口、排风管道和风机将室内污浊空气排出室内;同时保证室内压力的稳定。

Answer: fresh air system is by air units, air pipes and air, the outdoor fresh air into the room after treatment, through the air inlet, exhaust pipe and fan will discharge the indoor air indoor; while ensuring the stability of the pressure chamber.

2、新风有什么用?

2, what's the use of the new wind?

答:新风起到不开窗净化空气的作用,能减少室内空气中有害物质和有害气体,保证室内空气的含氧量,有利于健康。

Answer: fresh air does not play the role of window cleaning air, can reduce indoor air harmful substances and harmful gases, to ensure the indoor air oxygen content, is conducive to health.

3、新风都有什么类型?

3, what types of new wind?

答:家装常用新风机组有单向流、自平衡、双向流、全热交换四种。

Answer: home improvement commonly used fresh air unit has one-way flow, self balancing, two-way flow, full heat exchange four.

4、新风机组功耗多少?

4, fresh air unit power consumption?

答:新风机组的耗电部件是风机的电机,相当于风扇的耗电量,家装新风机组的耗电量一般在100W以下。机组风量越大耗电量越大。

Answer: fresh air unit power unit is fan motor, equivalent to the fan power consumption, home improvement fresh air unit power consumption is generally below 100W. The greater the power consumption of air units.

5、噪音如何?

5. How is the noise?

答:家用新风机噪音一般在30-40分贝。高、中、低三档中,高速噪声最大,低速最小。

Answer: domestic fresh air machine noise is generally 30-40 decibels. High, medium and low grades, high noise, low minimum.

6、新风用多大的机器,如何计算?

6, the new wind with the big machine, how to calculate?

答:可按两种方法计算:

Answer: can be calculated in two ways:

(1)换气次数:家装换气次数一般选择 0.75-1次/h, 风量=房间面积 X 层高 X 换气次数。

(1) the number of ventilation: home improvement ventilation generally choose 0.75-1 times /h, air volume = room area X, height X, ventilation times.

(2)人均新风量:每人每小时30-50立方米的新风量,风量=人数 X 人均新风量。

(2) fresh air per person: fresh air volume of 30-50 cubic meters per person per hour, air volume = X per person, fresh air per person.

例如:一15平方主卧室,层高2.5米,按照方法1计算得到小时新风量为15*2.5*1=37.5立方米,按照方法2计算时,主卧室内人数按照2人计算,则需要的小时新风量为2*30=60立方米两种计算结果,选择较大的一个作为选型依据,即该房间每小时需要60立方米的新风量。其余房间也按照该方法计算,各房间总风量之和小于等于选择的新风机组的最大风量。

For example: a 15 square master bedroom, 2.5 meters high, 1 hours are calculated according to the method of fresh air volume of 15*2.5*1=37.5 cubic meters, according to the 2 methods of calculation, the number of master bedroom in accordance with 2 calculation, need for hours of fresh air volume of two cubic meters 2*30=60 calculation results, choose a big one as the basis for selection, namely the the room needs fresh air volume of 60 cubic meters per hour. The remaining rooms are also calculated according to this method. The sum of the total air volume in each room is less than the maximum air volume of the selected fresh air unit.

7、什么场合如何区分?

7, what occasions, how to distinguish?

答:根据不同场所的换气次数和人均小时新风量,家装0.75—1次/h,商场1.6—3.9次/h,计算机房1.1—2.7次/h,体育馆2.5—6.3次/h,小型会议室3-5次/h,大型会议室8次/h左右,饭店、KTV6—8次/h,计算出总新风量,然后选择风机型号。

Answer: according to different places of the number and quantity of fresh air per hour, 0.75 - 1 /h home shopping malls, 1.6 - 3.9 /h, computer room 1.1 - 2.7 /h 2.5 - 6.3 /h, gymnasium, small meeting room 3-5 /h, large conference room 8 /h, hotel, KTV6 - 8 /h, calculate the total quantity of fresh air, and then select the fan model.

8、风管和风口有关系吗?

8, wind pipe and tuyere have relation?

答:有关系,新风经新风管道、风口送入室内,风口和风管如果连接的不紧密会导致漏风,所以在选择风口是口径要与跟它连接的风管一致。

Answer: Yes, the new wind through the new air pipe, air inlet into the room, the air outlet and air duct, if the connection is not tight, will lead to leakage of air, so the choice of air outlet is the caliber to be connected with the wind pipe it is connected.

9、全热交换是什么意思?

9 what does "total heat exchange" mean?

答:全热包含显热和潜热。显热:高温空气和低温空气因温差传递的热量,潜热:高温空气中水蒸气凝结时散发的热量。

Answer: full heat contains sensible heat and latent heat. Sensible heat: the quantity of heat transferred by high temperature air and low temperature air. The latent heat is the heat emitted by the condensation of water vapor in high temperature air.

10、全热交换有什么用途?

10, what is the use of full heat exchange?

答:节能,降低或提高进入室内空气的温度,降低空调负荷。

Answer: energy saving, reduce or increase the temperature into the indoor air, reducing air-conditioning load.

11、什么是自平衡风机?

11. What is a self balancing fan?

答:可以理解为风机上加装一个分支器,一分多。

Answer: it can be understood that the fan installed a branch, more than one point.

12、什么是单向流风机?

12. What is a one-way flow fan?

答:单一流向的风机,只能当做进风或者排风使用。

Answer: a single flow fan can only be used as air intake or exhaust air.

13、他们各自有什么区别?

13, what are the differences between them?

答:单向流的风机进入室内的只有一根主管道,需要在进入每个房间时做三通分支,主管道需要根据风量的变化做变径,自平衡的风机接出的是多根管道,每跟管道一般单独带一个风口。

Answer: enter the indoor fan and the unidirectional flow only one main pipeline, need to do three branch on entering each room, the main pipeline needs to be done according to the variable air volume changes, since the fan is connected with the balance of multiple channels, each with a separate pipeline with air inlet.

14、主机安装有什么主意事项?

14, what are the main idea of the host installation?

答:主机吊装要保持水平、牢固,与顶和天花间留不小于两公分的间距,距墙留下不小于50公分的空间方便检修。

Answer: host lifting should maintain level, firm, and between the top and ceiling, not less than two cm spacing, leave the wall not less than 50 centimeters of space, easy to overhaul.

15、风口安装有什么要求?

15, tuyere installation what are the requirements?

答:风口安装牢固、并与风管连接紧密,风口调节到适合的开启度。

Answer: the air outlet is firmly installed, and it is tightly connected with the air pipe, and the air outlet is adjusted to the proper opening degree.

16、地出风如何安装?

16, how can the ground wind be installed?

答:地出风扁管一般敷设在地暖保温层中,地出风口可安装在地面或墙壁上,分支器安装在墙角(方便处理主立管),从外到内顺序为:不锈钢风口——新风软管—PVC主管—新风软管—新风主机—新风软管—pvc主管-—分支器—风量调节阀—地送风扁管(直接、弯头)—地出风风口。

Answer: a flat tube generally laid in the warm wind in the heat insulation layer, ground outlet can be installed on the ground or on the wall, installed in the corner branch (easy processing main riser), in order to from the outside: stainless steel hose - PVC - Air Outlet Supervisor - the air hose - the air - air hose - machine PVC Supervisor - Branch - valve - to air tube (direct, elbow) - a wind outlet.

17、上出风如何安装?

17, how to install the upper air?

答:上出风新风和排风管道均为PVC管,并且全部隐藏在天花上,安装时应该尽量避免交叉、尽量减少排风管道的长度和软管的长度。

Answer: on the wind, fresh air and exhaust pipes are PVC tubes, and all hidden in the ceiling, the installation should be avoided as far as possible, and minimize the length of exhaust pipes and hose length.

18、地出风和上出风有什么不同?

18, what is the difference between the ground wind and the upper air?

答:地出风将排风管和新风管分层敷设,避免了施工中出现的因管道交叉影响风量的情况,节省了吊顶上部的空间。特别是在部分房间不吊顶的场合,用地送风仍可以实现送风口和排风口对角布置,并且新风下送上回,气流组织更合理,舒适度更高。但成本比上送风高出20%—40%。

Answer: ground wind, the exhaust pipe and the new air pipe laying, to avoid the construction of the cross pipe due to the impact of air volume, saving the upper part of the ceiling space. Especially in some parts of the room do not ceiling, the ground delivery can still be achieved ventilation and exhaust outlets diagonal layout, and fresh air delivery, air flow organization more reasonable, higher comfort. But the cost is 20% - 40% higher than the previous air supply.

19、家用机器有多大?

19. How big are household machines?

答:常用的家用全热交换器型号有:150风量/250风量/350风量/500风量

Answer: commonly used household heat exchanger models are: 150 air volume, /250 air volume, /350 air volume, /500 air volume

20、安装完后期要注意什么?

20, what should pay attention to the end of the installation?

答:安装完毕后要对各出风口的风量进行调节,上送风可调节风口开启度,地送风调节风量调节阀,确保系统不漏风。

Answer: after installation, the air volume of each outlet shall be adjusted. The upper air supply can adjust the opening degree of the air outlet, and the ground air supply shall be adjusted to adjust the air flow control valve to ensure that the system does not leak air.

21、新风带过滤吗?

21, fresh air filter?

答:带,新风机组内有过滤的滤网。

Answer: belt, fresh air units within the filter screen.

22、全热交换的工作原理?

22, the principle of full heat exchange?

答:利用新风和排风气流的温差和水蒸汽的分压力差进行显热和潜热回收的。

Answer: use fresh air and exhaust air flow temperature difference and water vapor partial pressure difference for sensible heat and latent heat recovery.

23、安装新风位置选择有什么要求?

23, installation of fresh air position selection, what are the requirements?

答:吊顶上部空间满足安装高度要求、距墙

Answer: the ceiling space to meet the installation height requirements, away from the wall
