Air Balancing Is The Method Of Optimizing An HVAC System So That Air Temperatures Are Consistent, …

The principle goal of air balancing is increasing the cooling efficiency of the air conditioner, reducing the heating costs during the winter months, air balancing can also assist to improve the performance of the HVAC system, reduce energy bills and increase comfort levels. There are several benefits to air balancing including increased air quality, increased energy efficiency, comfort and safety for family members. There are many techniques and methods used to do air balancing. All of these methods can be divided into two main categories: mechanical and electrical.

Mechanical Air Balancing involves a pump that draws air into a conditioning system through a tube. The size of the tube must be determined because the larger the tube, the more air is drawn into the system. Pipes are placed inside the housing to direct the air flow. This system operates on the principles of enthalpy and kinetic energy. Kinetic energy is simply the power of motion or movement contrary to gravity.

Enthalpy refers to the rate of heat transfer in a given area.A higher enthalpy value 75081 means a faster rate of heat transfer. Air flows at various velocities through the tubes that are set inside the housing.When 1651 N Glenville Dr. Ste 201 a fan speed is provided to influence the airflow, more air is trapped inside the tubes than the outside air. This results in more cooling or heating depending upon the difference in velocities. The fan speeds and the variations in fan speeds that are controlled by air balancing control devices are typically set in such a way as to increase air flow without adversely affecting enthalpy.

Energy Efficient Air Balancing Testing A system with air balancing can benefit from energy efficient testing. A good energy efficiency testing program should first determine the efficiency ratio of the air balancing system. Then, the system’s effect on overall system performance should be determined. Performance testing should include both an analysis of the energy savings achieved through the system as well as an examination of system operation under specific operating conditions.

Typical Testing Typical air balancing systems are evaluated using a variety of testing techniques. These include the use of the principle of total pressure air flow testing, peak airflow, turbulent airflow, positive displacement and mixed zone testing. While peak airflow determines the maximum amount of air flowing through the ducts, turbulent airflow determines the actual turbulence that occurs within the ducts. Mixed zone testing combines peak with mixed flow conditions in order to better assess the effects of thermal expansion and contraction.

Electrical Testing is used to verify the electrical power consumption of a system as well as the efficiency of electric motors and components. It is especially important to examine the electrical load on the air conditioning condenser and blower. Finally, electrical testing can reveal the existence of any discrepancies in the regulation of refrigerant temperatures. The results obtained by electrical tests can help the manufacturer to design a more effective air conditioning and heating system.

Mechanical Testing When mechanical testing is performed on air balancing ducts, they are usually tested for noise reduction and air flow control. Noise reduction tests can measure the sound levels originating from outside air conditioning ducts entering the indoor air conditioner.In addition, the air flow control tests can determine how effectively the air conditioner directs (972) 818-9000 air indoors. Air flow rate control tests are


important for ducts located near other electrical equipment such as outlets. The results from this test can influence the operation of the entire system.

As you can see, there are many different aspects of air conditioning duct testing which depend upon the testing method utilized.However, it is important to note that most testing programs follow commissioning agent industry accepted guidelines, which provide for thoroughness and validity.When commissioning a duct testing program, it is important to work with Rirchardson an experienced air conditioning and heating specialist. A professional air conditioning and heating specialist can make sure your duct systems are properly balanced to prevent system failure or energy wastage
