What Does TAB Mean in HVAC Terms?
What is meant by the abbreviation tab in HVAC?
If you are living in Haysville, Kansas, or some other place, you may have already encountered different HVAC terminologies and acronyms, some of which seem technical. And if you are involved in a commercial or large residential HVAC project, TAB is one of the acronyms you are likely to come across, however, what exactly does it stand for. What is the purpose of TAB with respect to your HVAC system?
On this blog, we examine in detail what the abbreviation TAB represents explain its function in an HVAC system and explain why it is necessary to ensure that there is a balance between ease of use and energy efficiency when controlling indoor spaces in any building. Premier Comfort Solutions will show you how TAB explains your HVAC system regardless of whether it is the first time you have heard it or you are already used to the acronym’s mention.
What is HVAC TAB?
TAB stands for Testing, Adjusting, and Balancing and in context with HVAC, it is a process that is focused on the post-installation of the HVAC systems that ensures that the system operates to the best of its abilities at the highest efficiency. This process is important for residential and commercial HVAC installations but most often associated with oversized systems where it is necessary to accurately control the air volume and temperature.
This is the first procedure in a series of procedures known as TAB. Testing takes place where the technician needs to evaluate the performance of the HVAC system in terms of airflow, temperature, and system pressure. By gathering accurate data, technicians can determine whether or not the system is performing up to the standard.
After testing the HVAC system, the next process is focusing on the test outcome and adjusting the HVAC components as appropriate. Adjustments can be done on fan speeds, some dampers may be opened or even shut, and controls may be recalibrated to make sure the system functions as required according to the design.
Sometimes, it is done incorrectly and this type of situation is addressed by the last stage which is known as balancing. In this phase, parameters like air and water (such in the hydronic systems) are ensured to be evenly dispersed inside the building. In such an unbalanced system, some parts may be overheated, other still will be cold, which is a bad experience in terms of efficiency.
After all, in a complex TAB Process that may be construed as a balanced performance of energy expenditures and thermal comfort provided for the users of the premises.
Why Is TAB Necessary for HVAC Systems?
Effective testing, adjusting, and balancing of an HVAC system has a number of advantages. In summary, here are the advantages of TAB to the maintenance of a complete HVAC system, a system that is in working condition:
- Energy Efficiency
One of the most important objectives of TAB is the reason why energy wastage can be addressed. An unbalanced system is likely to cause overheating or overcooling in parts of the house or facility leading to overworking of the HVAC system. This will lead to a higher expenditure on energy and in the long run, increased electricity bills. The practice of TAB assures that the system is working as intended since all areas would be served with adequate air without wasting energy resources.
- Enhanced Comfort
Do you sometimes feel like you’re getting too much heat in one part of the house and not enough in another? You are right, this could mean that your HVAC system is unbalanced. If your system is unbalanced it would mean that you still have to work very hard to heat or cool the space since you will not be able to maintain a desired temperature at all times. TAB assists in this task by ensuring that there are no temperature differences in any room by distributing the air evenly.
- Extended System Longevity
Without a proper balance of your HVAC system, some of its components may revolve a higher workload than intended, which may lead to damage over time. Such instances are detrimental as it decreases the lifespan of the system, thereby, increasing its chances of breakage requiring repair or early replacement. This, however, can be avoided by going through the TAB process as it primarily serves to extend the lifespan of HVAC systems by availing resources that should work together when needed to do so.
- Adherence to Design Parameters
TAB is mandatory, especially in larger commercial systems, as it acts to protect the specifications that the HVAC system should comply with the design created at the onset. Most of the commercial facilities are installed with intricate artificial Climate Control mechanisms that are made to satisfy certain air flow, temperature and ventilation levels. In the absence of optimal TAB, such systems might achieve none of those goals, leading to ineffectiveness and perhaps, regulatory violations.
- Improved Indoor Air Quality
In addition, a well-balanced HVAC system is conducive to good indoor air quality. Whilst your system is balanced, the pressure difference between outlets and inlets maintains constant air circulation which helps eliminate poorly circulated areas that if neglected, can result in other unsatisfactory aspects of air quality. This is especially needed in a house with possible asthmatic or allergy sufferers since circulating air will help in filtering the dust, allergens and other pollutants away.
The TAB Process Unfolded
After carefully reading the description to get an overview of the steps involved in the TAB process, let’s dig deep into the individual steps in the FHA TAB Process:
- Testing
The testing phase begins once the systems have been installed. Here, HVAC specialists strive to evaluate the performance of the installed systems using appropriate instruments and equipment. Some of the key parameters tested include:
Airflow: Measuring airflow is vital in confirming that the right quantity of conditioned air is distributed to each room or zone. All these procedures involve the use of anemometers and other devices to measure airflow rates at strategically placed vents or diffusers.
Temperature: In order to accomplish this goal, technicians will also measure the temperature of air from one of your HVAC Systems’ air supply system in order to see whether the system’s results are what would be expected.
Pressure: In moving air or water around, HVAC systems generate a certain pressure within a range. It is important to avoid too much or too little pressure as it would lead to the system underperforming, hence the need to measure system pressure.
- Adjusting
After testing is completed the technician will adjust the settings of the system to ensure it works more optimally. Some of the adjustments include:
Calibrating Controls: You’re bound to recalibrate thermostats and other controls in the room to correspond to the distinctly through walls of the HVAC System.
Adjusting The Dampers: Dampers help to regulate the air flow in the duct work. The distribution of air to every room or zone is evened off by adjusting these.
Fan Speed Adjustment: It might sometimes be necessary to alter the speed of the HVAC fan in order to enhance the efficiency of air flow in the system.
- Balancing
In the balancing phase, the queriers calibrate the system to guarantee the payoff of air, or water is done evenly. This involves:
Air Balancing: This is the case when treatment air and its associated loads should be supplied in the required amount to each room or zone and such requirements exceed what is supplied by the system. This may include changing the position of diffusers or vents to maintain airflow.
Water Balancing: In hydronic systems such as radiant heating or cooling, water should be evenly distributed over each zone to ensure an appropriate surplus of heat or cooling is supplied.
The objective of balancing is to ensure that the hydronic heating ventilation and air conditioning system provides an even temperature across the zones in all the conditions while being as efficient as possible.
Are Tab for HVAC systems appropriate for residences?
ire the generally large commercial HVAC systems but can also be applicable to residential units and this is especially true for large or multi-zoned residences. For example, residents who have observed variability in heating or cooling of their homes as well as those with unusually high energy cost bills may benefit from a TAB evaluation. Premier Comfort Solutions offers such evaluation facilities and advises if TAB operations will lead to maximum performance of the system.
