According to the construction requirements of civil engineering, the pipe sleeve must be set when the pipe of central air conditioning passes through the wall, and the steel sleeve needs to be replaced when the pipe passes through the floor

The preparatory work for the construction of central air-conditioning is a complex and systematic project
.

.
The equipment list and material list are the main basis
.
Only in this way can we ensure the normal operation of the whole central air conditioning system, and finally realize the stable, safe and efficient operation of the central air conditioning system
.
The conflict in different construction process, for the construction of fire control, water conservancy, power distribution and other projects in the building, there may be equipment crossing and pipeline overlapping
.
Generally speaking, in the design of the central air-conditioning manhole, the quality should be guaranteed first, and then the aesthetics can be considered
.

.
The equipment list and material list should be strictly reviewed
.
It is necessary to accurately locate the pipeline elevation, waterway system, air duct system and fire pipeline in the construction drawing
.
When installing the indoor and outdoor units of the central air conditioner, first determine the position of the internal unit, then mark the line, mark the position, hit the expansion bolt, and then hoist the indoor unit
.
Check the technical requirements of the construction drawing
.
Before the construction of central air-conditioning, we must make good preparations, including getting familiar with and reviewing the contents of the design drawings, and sorting out the construction acceptance standards, construction standards, construction plans, and Construction Group plans of the project in strict detail
.
Only in this way can the normal operation and management of the air-conditioning system be better guaranteed
.
Therefore, we must do a good job in the audit work and strictly control it
.
The manhole should be set under the ceiling corresponding to the equipment and pipe valves

Later, in the process of construction implementation, we must strictly review each link to ensure the compliance of central air conditioning in the construction and management process To ensure the quality of the whole construction process
.
As the Construction Party of central air conditioning, the following measures can be taken in the face of the above problems: (1) first of all, try to improve the equipment as much as possible Take high layout, so that the condensate pipe has a larger space, will not affect the standard height of the ceiling; (2) in the central air conditioning water system pipeline must avoid other equipment, in order to avoid the problems caused by the water circulation system, should add more exhaust device at the higher point of the pipeline, so that the gas can be discharged smoothly

What key points should be paid attention to in construction? 1
.
1
.
There must be no weld in the pipe, and the galvanized iron casing must reach the horizontal height with the floor and wall
.
The gap between the pipe and the sleeve needs to be filled with heat insulation and insulating materials, and the sleeve is not allowed to be used as the support of the pipe
.
For some special or uncommon technical requirements in the construction drawing, we must pay enough attention to check the construction drawing
.
Check the preparation of the air duct system and water channel system
.
2
.
Before the construction of central air conditioning, the equipment and materials must be purchased
.
Before the formal construction of the central air conditioning, we should have a clear understanding of the air duct and water channel system of the central air conditioning
.
Therefore, when it comes to the structure of the house, reserved holes, shear walls and other problems, we should pay special attention to the possible loopholes and dislocations in the future construction process It is absolutely not allowed to open the shear wall and the side wall of the core tube, otherwise it will not only affect the safety of the whole floor, but also lead to irreparable economic losses

We need to inquire about customer service: order processing, product customization, product inquiry, design and construction, membership registration, WeChat group and QQ group
.
(3) In the construction of air duct system of central air conditioning, due to the large space of air duct system, in order to ensure the standard of air duct section size, the longitudinal height must be reduced
.
The construction management process of central air conditioning is a complex and systematic process
.
Among them, the construction drawing is the more important thing in the construction, it determines whether it can accurately complete the construction task of central air conditioning on time, quality and quantity
.
Carefully check the construction drawing before the construction of central air conditioning, carefully check the correctness of the construction drawing can effectively avoid the collision between various systems, and improve the one-time success rate of central air conditioning construction
.
The construction party, the construction party and the designer of the project should communicate effectively on site
.
If there are problems in these two aspects, it will cause irreparable economic losses
.
First of all, we should pay attention to the importance of central air conditioning construction management in the whole construction process ideologically, and then formulate feasible measures according to the actual situation
.
