Assembled machine room should not excessively pursue “box” modularization
The on-site prefabrication processing is basically manual operation, which will produce a large number of leftover materials, and the construction quality is not easy to control.
The professional processing factory produces pipe components according to the drawings optimized by BIM, numbers all pipes according to the assembly sequence, and assembles them according to the number during on-site installation.
It is not advisable to excessively shorten the construction cycle and increase the so-called cast highlights, but it will bring many problems.
3) In order to minimize the box space, the inlet and outlet pipes of the water pump are stacked and connected with the valve parts, increasing the local resistance loss of the pipeline, resulting in non energy-saving operation.
Using BIM Technology to optimize the design of equipment room and the construction methods of factory prefabrication and on-site assembly are the direction of building electromechanical installation industrialization.
2) After modular integration, similar containers need large transportation vehicles and handling equipment, which increases transportation and handling costs and brings safety risks.
5) The bottom profile steel frame is easy to corrode.
The installation method of professional factory prefabrication and on-site assembly can avoid on-site welding pollution and meet the requirements of green construction.
Regardless of the actual situation and demand of the site, the machine room is divided into several modules for assembly, especially the overall modular processing of the water pump unit.
6) The equipment vibration and pipeline are transmitted to each other through the frame, and the vibration isolation effect is poor.
In some projects, in order to highlight the short construction period of on-site installation, the modular assembly machine room is excessively pursued.
However, the so-called modular “box” integrated machine room should not be pursued too much for the precast machine room with factory processing.
1) The addition of large-size section steel frame consumes a lot of steel and increases the installation cost, which is not a green construction.
The traditional construction method is to cut materials, manufacture and install on site according to the detailed construction drawings, which is carried out cross with the civil construction, and the installation cycle is long.
In this way, the on-site assembly construction cycle is shorter and the installation efficiency is higher.
4) For modular box handling, the elevation of the horizontal main pipe section had to be reduced, which did not comply with the overall layout principle of the pipeline in the machine room; If the pipeline elevation is increased, large steel frame specifications need to be added, which will greatly increase the cost, and improve the overall box center of gravity, which will bring greater hidden dangers to safe transportation.
During factory prefabrication, properly improve the processing integration rate and reduce the on-site assembly quantity, which can more effectively shorten the construction period.
The air conditioning and refrigeration room is the place where the construction electromechanical installation engineering equipment and pipelines are most concentrated.

The professional factory has a high degree of automation and intelligence, which can achieve accurate blanking and improve the pipeline processing accuracy; At the same time, factory unified optimization of material supply and optimization of processing, cutting and welding can greatly reduce component leftovers and effectively reduce costs.
