① Air distribution system ② Water distribution system ③ Automatic control system
3.3.2 Comprehensive Report
The composition of the comprehensive report is to be submitted by comprehensively organizing all items as specified in the ‘Technical Standards for Testing, Adjustment, and Evaluation of Air Conditioning Equipment’ published by the Korean Society of Air Conditioning and Refrigeration Engineers, so that it can serve as essential data for future air conditioning equipment operation management.
The purpose is to ensure that indoor air conditioning systems operate in optimal conditions by measuring whether air conditioning equipment installed in general buildings and industrial facilities is operating as designed using specialized personnel and precision measuring equipment, scientifically identifying the condition, and suggesting adjustments, problems, and solutions, thereby saving energy, providing a comfortable indoor environment, and extending the life of the equipment.
It is a task performed to efficiently operate a building's air conditioning system or indoor environment system, and is broadly defined in three stages.
| T (Testing) | A (Adjusting) | B (Balancing) |
|---|---|---|
| To evaluate the performance of air conditioning systems and equipment, temperature, pressure, rotational speed, electrical characteristics, flow rate, water quantity, and air volume are measured using precision measuring instruments. | In normal system operation, the control mechanisms such as dampers and valves are finally set to maximize appropriate performance and efficiency in addition to the automatic control mechanism. | Systematically regulates the fluid flow in a system through proper procedures to achieve the design value or given flow rate. |
In advanced countries, the trend has long been to move beyond simple building preservation and incorporate building management into design from the initial stage to minimize operating and maintenance costs. Furthermore, air conditioning equipment, which consumes the most energy, is mandated to undergo a TAB (Test, Adjust, and Balance) upon completion. In Korea, this requirement is also mandated in the "Standard Specifications for Building Mechanical Equipment" established by the Ministry of Construction and Transportation, contributing to energy savings and quality control.
Headache, nausea, dizziness, and fatigue due to lack of ventilation ⇒ Create a sense of comfort
Accuracy of test data is expected by meeting various test conditions.
The T.A.B service provider must perform the work as follows and submit the contents to the ordering party.
For all air conditioning equipment, a SYSTEM DIAGRAM for each SYSTEM and device must be created, and the DESIGN DATA and PHYSICAL DATA must be organized and reflected in the final report.
Through drawings related to the air conditioning design specifications and on-site inspections, we closely review and analyze problems and modifications from the T.A.B perspective and seek to establish countermeasures.
Before carrying out T.A.B work, the site is closely examined to determine whether the air and hot and cold water distribution systems, automatic control systems, etc. are consistent with the construction drawings, thereby devising the optimal method for T.A.B work and ensuring perfect construction.
Using precision measuring equipment, CHECK the wind volume, static pressure, and regulator settings, and perform BALANCING work by adjusting the damper to match the design values.
CHECK the flow rate, pressure, and regulator settings within the hot and cold water distribution system and PIPE and adjust them to match the design values.
Check the overall status by checking the operating status of control devices and checking the SETTING values.
CHECK the noise level of the machine room and air conditioning room, and if any abnormalities are found, analyze the cause and suggest solutions, and establish countermeasures in advance for any anticipated issues.
Take pictures of the on-site INSPECTION information, T.A.B work details, and other important details to enable visual identification of the current status.
The contents of the T.A.B work performed on site are written and organized according to a certain format, solutions to problems that arise are suggested, and a complete SYSTEM is established. After that, a booklet containing the contents is printed and presented.
The final T.A.B report has three functions and should be used to help improve the quality of future design and construction:
Since a design is a work born from conception and calculation, a report serves as concrete evidence of whether the design objectives have been achieved. It helps improve design quality by preventing trial and error in future construction design, and it instills confidence in designers when the original design intent is met.
It should be data that can detect construction omissions and errors, evaluate construction quality, and prove the performance of the automatic control SYSTEM.
The T.A.B (Testing, Adjusting and Balancing) task is a process for maintaining the performance of air conditioning systems. In the past, it was focused on testing and adjusting the elements and systems of air conditioning systems to ensure they meet the design purpose by putting them into operation at the time of completion of on-site construction.
Some of the problems in design, construction, and manufacturing discovered during T.A.B implementation have been improved through cause analysis and solutions presented, but a significant portion of them are not being improved even in cases of important functional problems due to inappropriate on-site conditions caused by non-construction.
Having experienced these problems, many clients have recently started ordering T.A.B services early, allowing the T.A.B performers to actively participate in design documents, equipment approval documents, and other technical inspection tasks, thereby providing feedback in advance on many problems discovered during T.A.B execution, thereby maximizing the effectiveness of T.A.B.
Additional benefits of early ordering include:
The purpose of this project is to contribute to the efficient operation of energy and the creation of a comfortable indoor environment by testing, adjusting, and balancing the cold and hot water distribution system for air conditioning and the entire air conditioning system.

Commissioning can be said to be a verification work to ensure that the performance of the building desired by the owner is actually realized.
In the case of existing CM, process management, contract management, and quality control have been carried out, but in the case of quality control, it was possible to verify the visible things to build the building according to the design drawings, but problems have arisen due to the lack of management plan and lack of expertise in the invisible performance part.
Therefore, it was difficult to verify whether the actual reflected systems were performing properly or whether the performance was implemented as intended, and even if problems were found, it was difficult to clarify whether they were responsible for whether it was a problem with the delivered materials or a problem with design/construction, so it was impossible to request a grounded guarantee.
In response to these problems, a systematic procedure called commissioning is introduced to establish a system for quality management related to performance, and it is a task to reflect the requirements related to performance that the owner truly wants in the actual building.
The system performance is secured according to the owner's intention.
By systematically and efficiently managing the construction process such as planning, design, construction, and commissioning, unnecessary additional construction costs due to unreasonable design or construction that appear during the construction process can be reduced.
By selecting highly efficient systems and equipment and improving operating technology, energy costs and operating costs can be reduced.
Information on the system's operation management methods is continuously modified and supplemented, so that operation and maintenance can be carried out efficiently.
By systematizing construction-related information through the implementation of commissioning procedures, the knowledge of operation and maintenance managers necessary to operate the system can be improved.
You will be provided with a system manual that can facilitate the operation and maintenance of equipment and systems.
Effective diagnosis of equipment and system failures can reduce the frequency of failures.
By improving the indoor environmental conditions of the living space, it is possible to provide benefits to the tenants of the building by providing a comfortable working environment, improving work productivity, and reducing complaints from occupants about indoor air quality.
Ensure that the various facilities and systems of the building meet the requirements of the owner.
Unsuitable designs can be improved before completion to reduce defect factors.
Through the performance evaluation workshop, future design data can be accumulated.
By collecting opinions from participants in each field, it is possible to set an efficient design direction.
Through consultation and coordination during the project execution period, it is possible to reduce confusion in the construction process due to unsuitable design.
Through commissioning, efficient construction plans can be established.
Efficient construction management can be achieved through business cooperation between other processes.
Through a systematic implementation process, it is possible to improve the quality of construction.
After the completion of construction, problems and defects can be reduced.
Driving-related defects can be reduced through driving manager training.
