Discussion on construction problems and countermeasures of ventilation and air conditioning engineering in high-rise buildings?

The following are the construction problems and countermeasures of ventilation and air conditioning engineering in high-rise buildings brought by Zhong Da Consulting for your reference.

China is in a stage of rapid development. With the economic and social development of China, people's living standards have been greatly improved, and people's pursuit of quality of life is getting higher and higher, which is reflected in the higher requirements for buildings and other related supporting facilities. Ventilation and air conditioning engineering is one of the main supporting projects in building engineering, which can improve the building environment, so ventilation and air conditioning engineering has attracted much attention at present. Ventilation and air conditioning engineering is a complex and comprehensive project, which is difficult to construct. Especially for high-rise buildings, there are often some problems in the construction process of ventilation and air conditioning projects, which affect the realization of ventilation and air conditioning functions. Therefore, effective measures must be taken to solve it and ensure the construction quality of ventilation and air conditioning projects.

1 common problems in ventilation and air conditioning engineering construction of high-rise buildings

In the ventilation and air conditioning engineering construction of high-rise buildings, some problems often occur, mainly in the following aspects:

1. 1 ventilation and air conditioning have large air leakage.

There are many reasons for the large air leakage of ventilation and air conditioning, mainly two: (1) the specification and model of flange are used incorrectly, resulting in air leakage; (2) The flange gasket was not installed in the installation process, resulting in the connection between the ventilation pipe and the flange being not tight enough.

1.2 uneven installation of ventilation pipes.

At present, in the installation process of ventilation and air conditioning in high-rise buildings, many construction links are naked. If there is a deviation in installation, the angle of the ventilation pipe will be uneven and uneven. This not only affects the aesthetic feeling of the whole building, but also affects the quality of engineering construction to some extent.

1.3 Water leakage and seepage in ventilation and air conditioning.

Water pipe leakage and seepage are common problems in ventilation and air conditioning engineering construction of high-rise buildings. Among them, the water leakage parts of water pipes are mainly concentrated at the joint of valves and components, as shown in the following figure. The main reason for water leakage is that the installation regulations are not strictly observed during the production and installation, such as the plastic positioning of the silk mouth; There are two main reasons for water seepage in water pipes. The first reason is that the water pipe is broken, which leads to cracks during installation. The second reason is that the thermal insulation layer is not closely attached to the water pipes and pipelines of the air conditioner during the thermal insulation operation, or a support bracket is used, and there is no wooden pad on it.

1.4 air conditioning filter screen is blocked.

Some human factors will affect the function of ventilation and air conditioning. Common problems are filter blockage. Because the filter screen of the air conditioner is blocked, although there is still wind blowing from the fan during the normal operation of the ventilation air conditioner, it can not improve the indoor air and reduce the indoor temperature, which affects the normal function of the air conditioner. The blockage must be removed in time to ensure its normal function.

In the ventilation and air conditioning engineering of high-rise buildings, in addition to the above problems and reasons, there are also some reasons that will affect the normal operation of air conditioning. These problems, including the failure to install the corresponding exhaust valve and drain valve at the top of the ventilation system and the minimum living setting, have all affected the normal operation of ventilation and air conditioning.

2 Countermeasures to solve these problems

Regarding the appeal, the main reason is that the relevant specifications have not been put in place during the construction process, and there are some human factors. In order to ensure the quality of ventilation and air conditioning engineering in high-rise buildings, the following aspects must be done well:

2. 1 Make corresponding preparations before the construction of ventilation and air conditioning project.

Before the construction of ventilation and air conditioning engineering in high-rise buildings, the preparation work that needs to be done is mainly the preparation of materials, equipment and personnel.

For the materials and equipment used in the construction, the quality must be strictly controlled before the construction, from the beginning of procurement until the materials and equipment enter the site, and the unqualified materials must be replaced. In the process of entering the site, unpacking inspection should also be carried out to avoid someone replacing equipment and materials, and some more expensive materials, such as pumps and fans, should also be inspected emphatically. After the inspection of materials and equipment, the construction unit shall submit a report to the supervision unit, which can only be used after it is approved by the supervision unit. When submitting the report, it is also necessary to submit the certificate of conformity and inspection report of the relevant products. After the materials enter the site, they should be stacked in different categories, and corresponding protective measures should be taken. For example, some materials that are easy to rust should be waterproof and moisture-proof, and butter should be applied before use to avoid sticking.

In terms of staffing, in addition to strengthening the technical training of construction personnel, we should also strengthen the instillation of their safety awareness to ensure the high-quality and efficient completion of high-rise ventilation and air conditioning projects.

2.2 Strictly control the construction quality in the construction process.

In the construction stage of ventilation and air conditioning engineering, the construction should be carried out in strict accordance with the project construction plan and the resources should be allocated reasonably. All subdivisional works must be constructed according to their own drawings and technical specifications, and good communication and close cooperation should be maintained between subdivisional works. In the process of construction, we should also carefully study all the pipelines of the building, including water supply and drainage pipelines, electrical pipelines and fire-fighting pipelines. And then make overall plans and make reasonable arrangements. In the process of construction, comprehensive support is used as much as possible, which has the advantages of saving space, ensuring construction effect, being reasonable and beautiful.

In addition, in the process of construction, we should also strengthen on-site inspection and strengthen safety management. We must ensure that every construction operation is carried out in strict accordance with the construction specifications, and focus on supervising and correcting some bad construction habits. After the completion of each working procedure, the inspection and acceptance shall be carried out according to the specifications of design drawings, and the construction of the next working procedure can be carried out only after the quality is qualified.

2.3 quality control in the process of air conditioning decoration

For air conditioning decoration construction, the construction unit should communicate with the owner, combine the specific requirements of the owner, and carry out reasonable design according to the effect of air conditioning. If the decoration design is unreasonable, it will affect its normal function and bring certain security risks to the operation of air conditioners.

In the process of decoration construction, we should fully understand the room layout in the building and coordinate with the supervisor and the owner. If the design needs to be changed, the construction can only be carried out after the change document report is passed. In addition, it is necessary to strengthen the inspection in the construction process, especially for some places that are not easy to find, to ensure the construction quality.

2.4 Strengthen debugging and delivery.

After the air conditioning construction and installation is completed, it should be debugged in strict accordance with the debugging plan and scheme, including the debugging of air conditioning equipment and related parameters. In the process of single machine debugging and monitoring, corresponding debugging records should be recorded to ensure the authenticity and accuracy of the recorded information. After the completion of commissioning, the construction personnel should be trained accordingly to ensure that they can operate the equipment skillfully.

3 abstract

In the construction of ventilation and air conditioning engineering in high-rise buildings, there are problems such as water leakage, water seepage and large air leakage, which affect the normal operation of ventilation and air conditioning and lead to its failure to play its due role. Therefore, preparations should be made before ventilation and air conditioning construction, the construction quality should be strictly controlled during construction, and the decoration and debugging of air conditioning system should be done well. Only in this way can we ensure the construction quality of ventilation and air conditioning engineering in high-rise buildings and ensure that buildings provide more comprehensive functions for people's lives and work.
