Central air-conditioning: Central air-conditioning is an air-conditioning system that controls different rooms by means of a main unit connecting multiple ends through air ducts or cold and hot water pipes, so as to achieve the purpose of indoor air conditioning.

3. Calculation method of air distribution

The task of airflow organization calculation is to select the form of airflow distribution, determine the form, number and size of air supply outlets, and make the wind speed and temperature difference in the working area meet the design requirements.

1. Comparison between traditional air duct and phenolic air duct
The traditional air supply ducts of central air conditioners are usually made of iron sheet or fiberglass as the inner layer, wrapped with thermal insulation materials, and wrapped with aluminum foil on the outside, which makes the air supply ducts heavy and large, labor-intensive and time-consuming for construction and installation, poor in appearance, low in air tightness, and low in performance.

4.Condensate pipe installation
(1)The diameter of the condensate pipe must meet the technical requirements. The installation must be completed before the internal wall plastering and waterproofing of the civil works.
When installing the condensate pipe, it is necessary to spring the wire (apply for inspection), then use a cutting machine to build a groove, and then pick it out.

2) Fresh air volume

The fresh air volume of the air conditioning system shall not be less than 10% of the total air supply volume, and shall not be less than the larger value of the following two air volumes:

Ventilation plays a vital role in maintaining the atmosphere in a house. If you're working remotely or staying at home most of the time, the chances of you getting out into the fresh air and sunshine are small.

Air duct machine installation precautions, Come and learn together!

Although there are many ways to air condition the interior of a home, the duct system is the most effective, although it requires work. Despite this, it is not an excessively traumatic process, and the pre-installation of air conditioning ducts does not have to last more than two or three days.

3.water system
(1)The diameter reduction of PP-R pipes must be less than 3% when hot-melted, and the installation must meet the technical requirements of the manufacturer.

2) Air treatment process of fan coil unit + fresh air air conditioning system

The fresh air and the fan coil unit supply air to the air-conditioned room respectively. In this way, even if the fan coil unit stops running, the fresh air will remain unchanged.

When many carpenters are making suspended ceilings, they do not design the return air vent properly, and even seal the return air vent, which greatly affects the use effect of the air conditioner, and even greatly reduces the life of the air conditioner.

Nowadays, ventilation systems have become increasingly essential elements within homes, taking charge of renewing the air and reducing the high levels of humidity in the home.
