Weak current College】 【residential central air conditioning duct system using features.

Household central air conditioning is the central air-conditioner system application in the housing area is 80 ~ 600m2 more room between apartments, duplex apartments, villas, small office and small business space, therefore, with central air conditioning system with air duct, household central air conditioning duct system has the following characteristics:

(1)-issues fairly prominent

General air conditioning use in shopping centres, cinemas, offices and other public places, these parts of the story is generally quite high, so high layer is not very obvious, basically meet the central air conditioning duct system installation, use and maintenance needs. But for a domestic central air conditioning, since it uses place very often about the 3m storey high, generally around 2.8m, which requires its configured duct should be as few occupy storey space.

(2) air duct processing requirements for convenience

Residential central air conditioning duct system of processing capacity, the specifications, it can only conduct on-site processing. As a result of domestic central air conditioning duct construction site is generally smaller, and more on construction sites, and therefore not suitable for large-scale production machinery and equipment. In addition, each household household central air conditioning duct installation location may be different, unlike the Office buildings, malls, each floor layout of basic fixed, very often require onsite location, but you also need to be installed according to the specific situation of temporary processing pipeline accessories, such as elbows, large-diameter, thus requiring air duct processing is very convenient.

(3) the requirements for the noise is higher

The main domestic central air conditioning in the living environment is used, the requirements for the noise. Under the residential design code People's Republic of China, residential bedroom, living room (Hall) allows diurnal noise should be less than or equal to 50 DB, whereas the night should be less than or equal to 40 DB [3]. Air duct engine top pressure usually about 80 ~ 250Pa, noise, which requires household central air conditioning duct system equipped with noise control devices or itself has good sound absorption function.

(4) on the strength of the requirements of air duct may be appropriate to reduce the

Central air conditioning use occasions, such as shopping malls, office buildings, etc. can often be encountered large space, and therefore require duct has higher strength. Household central air-conditioning use occasions of span is generally smaller and are usually less than 4m, which makes the wind tube strength requirements can be reduced. In addition, domestic central air conditioning duct system of ventilation rate is smaller, the ventilation pipe required diameter is also relatively small, this can also be appropriate to reduce the intensity of the wind tube material.

You can see from the above analysis, the domestic central air conditioning duct system and central air conditioning duct system requirements are not identical, so the household central air conditioning duct system design and construction must take full account of these characteristics, in order to get a satisfactory residential central air conditioning duct system.
