Why is Outside Air (OA) Mixed with Return Air (RA)

EB Air Mixer

With the surge of global warming, an HVAC system is indispensable for hotels, organizations, offices, schools as the temperature keeps rising in hot and humid areas, even in cooler areas. Air stratification and improper mixing lead to the air mixer for AHU not working up to the design. This results in uneven temperature distribution, humidity build-up, and growth of mold spores which can be health hazardous while increasing the maintenance cost of the system.

Energy-efficient air mixers must be installed in every HVA system in every public building. Covid-19 being an airborne virus has taught us the importance of engineering proper mixer airflow in buildings.

What is a compact air mixer?

Compact air mixer is the only solution for air stratification in the plenum and coil freeze-ups. This design was engineered looking at the inconsistent temperature distribution, molds in walls, to provide respite from them at a minimum cost. The principles which led to the compact air mixer invention are:

  1. Mixing of two types of air layer by layer across the full plenum.
  2. Moving the air within the plenum without additional space.
  3. Mixing high ratio of air to optimize the flow field
  4. Energy efficiency

Benefits of mixing fresh air in the HVAC system

The most important goals which are accomplished through adding fresh air to the heater or cooling system are increasing the air quality of the building, creating pressure in the building. By adding fresh outside air to stale indoor air, a fresh air inlet is accomplished in most systems without burning pockets.

The outside fresh air is pulled inside through the filter and enters through the roof, sidewall vent inlet. Smaller systems use the suction side of the system to pull outside air into the system. The supply duct system spreads the mixed air evenly throughout the indoors of the building.

A volume damper is installed in the air duct to control the volume of the airflow. Another type of damper is the motorized shutoff damper that seals off the damper when the HVAC system is not working. Insulation is added from the outside of the duct to prevent outside heat or cold from entering the inside. The volume of return air is less than the supply air delivered into the building.

Then the supply pressure exceeds the return air and thus positive air pressure is maintained. The positive air pressure prevents the entering of outside air from unwanted locations, prevents airborne particles, germs, ducts, and irritants from entering the building.

How the BTU formula works for HVAC systems

To calculate the BTU entering into the building, the formula is:

Sensible fresh air BTU= (Fresh air CFM* temperature difference between the outside and the inside)* 1.08

The steps of calculation are:

  • The fresh air CFM formula is the amount of outside air being pulled into the inside or using the CFM design if the system is not built yet. Let us assume the CFM is 200.
  • Now calculate the temperature difference. For summer and winter, use the outside temperature and then subtract that temperature from the design indoor temperature of that season. Let’s assume the outside temperature is 20 degrees F, the indoor temperature is 70 degrees F, so the difference would be 50 degrees F.
  • Now multiply CFM 200 with the temperature difference 50 degrees F by the 1.08 constant. You will find the winter fresh air will add 10,800 BTU to the heating load of the indoors. If you have a natural gas furnace, the extra load will be handled by the heating system.

Conclusion

An energy-efficient air mixer is the need of the hour for any HVAC system in any public buildings. EB Air Control provides cost-effective and high productivity compact air mixers for HVAC systems. To book for air mixers or get more information from our experts, join our website today.
