The key points that should be paid attention to in the process of central air conditioning construction management
1. Preliminary preparations for central air-conditioning construction
The construction process of the central air-conditioning is a complex and systematic project. Before the construction of the central air-conditioning, preparations must be made, including the familiarization and review of the content of the design drawings, and the construction acceptance standards and construction standards of the project. , Construction plans, construction team plans, etc. must be strictly and detailedly organized. Among them, the construction drawings are the most important thing during construction, which determines whether the central air-conditioning construction tasks can be completed accurately and on time with quality and quantity.
1. The equipment table and material table should be strictly reviewed
The central air conditioner must purchase equipment and materials before construction. The equipment table and material table are the main basis. If there are problems in these two aspects, it will cause irreversible economic losses. Therefore, it is necessary to do a good job in the audit work and strictly control.
2, check the preparation of the air duct system and water system
Before the formal construction of the central air conditioner, we must have a clear understanding of the air duct and water system of the central air conditioner. Therefore, we must pay special attention to issues related to the structure of the house, reserved holes, and shear walls. For possible loopholes and dislocations, in the future construction process, we must avoid on-site wall digging. Shear walls and core tube sidewalls must not be allowed to dig holes, otherwise it will not only affect the entire floor The safety of the company has an impact, and even leads to irreparable economic losses.
3, carefully check the construction drawings
Before the construction of the central air-conditioning, carefully checking the correctness of the construction drawings can effectively avoid collisions between various systems and improve the one-time success rate of the central air-conditioning construction. Specifically, whether the pipeline elevation, water system, air duct system, and fire-fighting pipeline in the construction drawings collide, the construction must be accurately positioned.
4. Check the technical requirements of construction drawings
For some special or infrequent technical requirements stipulated in construction drawings, sufficient attention must be paid to the verification of construction drawings.
2. Several key points that should be paid attention to during the specific central air conditioning construction process
1. Conflicts in different construction processes
For the construction of fire control, water conservancy, power distribution and other projects in the building, there may be equipment crossing and pipeline overlap. The construction party, construction party and designer of the project should communicate effectively on site as the construction party of central air conditioning. The following measures can be taken when facing the above problems:
(1) First, the equipment should be arranged as high as possible, so that the condensate pipe can have a larger space and will not affect the standard height of the ceiling;
(2) When the water system pipeline of the central air conditioner must avoid other equipment, in order to avoid the problems caused by the water circulation system, an exhaust device should be added at the highest point of the pipeline, so that the gas can be discharged smoothly.
(3) In the construction of the air duct system of the central air conditioner, because the air duct system occupies a relatively large space, in order to ensure the standard of the air duct section size, the longitudinal height must be reduced.
2. Construction requirements and civil engineering
Pipe sleeves must be installed when the pipes of central air-conditioning pass through the wall, and steel sleeves need to be replaced where the pipes pass through the floor. There can be no welds in the pipe, and the galvanized iron sleeve must be level with the floor and wall. The gap between the pipe and the casing needs to be filled with heat insulation and insulating materials, and the casing must never be used as a support for the pipe.
3. Install indoor and outdoor units of central air conditioning
When installing the internal and external units of the central air conditioner, first determine the position of the internal unit, then mark and mark the position, hit the expansion bolts, and finally hoist the indoor unit.
4. Design problems of central air conditioning access
Generally speaking, when designing the central air-conditioning access port, s* must first ensure the quality, and then consider the aesthetics. The access port should be set under the corresponding ceiling of the equipment and the pipeline valve. Only in this way can the air-conditioning be better guaranteed. The normal operation and management of the system.
The construction management process of central air-conditioning is a complex and systematic process. First of all, we must pay attention to the importance of central air-conditioning construction management in the entire construction process from the ideological level, and then formulate feasible measures based on the actual situation, and finally, in the process of construction implementation In the process, each link must be strictly reviewed to ensure the standardization of the central air-conditioning in the construction and management process, and thereby ensure the quality of the entire construction process. Only in this way can we truly guarantee the normal operation of the entire central air-conditioning system, and ultimately realize the stable, safe and efficient operation of the central air-conditioning system.
