Central air conditioning ceiling height:
The installation height of central air-conditioning ceiling is determined according to the thickness of air-conditioning pipeline, drainage space and the host machine thickness of central air-conditioning indoor unit, mainly based on the thickness of central air-conditioning indoor unit. The general installation step is to install the pipes and drainage slopes of the central air conditioner to make them as close as possible to the ceiling wall, and then determine the ceiling thickness of the central air conditioner according to the thickness of the indoor unit.
For example, if the thickness of the indoor unit of the central air conditioner is 20cm, then adding the thickness of the pipeline and 5cm of the drainage space, it is necessary to reserve a size of 25cm to install the central air conditioner. Although different brands of indoor units have different thicknesses, the slopes of pipes and drainage are roughly the same, so the size of the central air conditioner to be used should be determined before making the ceiling.
Central air conditioning outlet size:
Different from traditional cabinets and wall-mounted machines, the size of the air outlet/air return port of central air conditioner is not clearly defined, because it is carried out synchronously with indoor decoration, and the indoor machine is hidden in the ceiling. In the actual design and installation process, it needs to be mastered flexibly according to the family decoration, and the size of the air outlet/air return outlet depends on the capacity of the indoor unit.
Generally, the air outlet size of central air conditioner is: air outlet 15cm×60- 100cm, return air 23cm×60- 100cm, manhole 35cm×35cm. The width of the air outlet and return air can be basically determined, but the length should be reasonably designed according to the length of the indoor unit and the decoration environment.
Design standard of central air conditioning air outlet:
The size of the air outlet of the central air conditioner depends on the capacity of the indoor unit. If the air outlet of the central air conditioner is too large and the air duct is too long, the wind speed will decrease, thus affecting the use effect of the air conditioner. If the size of the air outlet of the central air conditioner is too small, the airflow speed will increase, which will cause discomfort when the wind blows directly on the human body, and may also lead to excessive noise.
There are three main return air modes of central air conditioning: side return air, lower return air and side return air. Because the wind speed of the air return of central air conditioning is generally greater than that of the air outlet, the area of the air return is greater than that of the air outlet under the condition of constant air volume. In addition, it is best not to set a lamp slot at the air outlet of the central air conditioner, which will easily cause the hot air flow to fail to reach the personnel activity area and affect the heating effect.
What kind of room is suitable for installing central air conditioning?
Because the indoor unit of central air conditioning is hidden in the ceiling, it depends on whether the room type is suitable if you want to install central air conditioning at home! A house that is really suitable for installing domestic central air conditioning needs to meet the following two basic conditions: first, the house should be high enough with a floor height of at least 2.7 meters; Secondly, the area should be large enough, with a total area of more than 80 square meters, because only large-area houses can really save energy consumption, and small-sized houses are not cost-effective; Therefore, users of duplex buildings, large-area apartments and villas can give priority to household central air-conditioning products.
