（AHU） = THE ENERGY …
Experimental results show that the power consumption of the heater decreases 50.4%, the power of fan with frequency converter reduces 89.6%, however, a 1.2% power of refrigerating machine is reduced. Overall, the AHU with bypass duct and converter can save 40.2% power consumption in the air-conditioning system.
CHAPTER -1: INTRODUCTION TO AIR HANDLING UNITS (AHUs)
Noise refers to unwanted sound generated by the AHU and air delivery ductwork during its operation. and low air velocities (below 1500 fpm main, 800 fpm branch). Quiet AHU: Opt for sound attenuators, acoustic insulation, conservative duct size 7. Basic Parameters for AHU Selection Here''s an example of how you might specify the rating of an AHU: a.

AHU Fans Measurement Guide
AHU systems are operated year-round, though operating rules differ between heating and cooling season. Ventilation requires a minimum air flow rate during occupied periods. If heating and cooling is not needed, the AHU could be shut down completely during unoccupied periods, provided the system has the capacity to re-establish desired indoor ...
Improving performance of AHU using exhaust air potential by …
In this study, the exergy analysis of an AHU equipped with a heat and exergy recovery unit was investigated. The equations obtained from energy and exergy balance were solved based on a program developed in engineering equation solver. Through the air-to-air heat exchanger, the energy is transferred from the fresh air to the exhaust one but the exergy is …
Control Functions of Air Handling Unit(AHU) are impacting energy ...
In Air Handling Unit(AHU), filter becomes contaminated which causes a higher airflow resistance. If the fan capacity is not regulated then the amount of air supplied or extracted from the building will be reduced.The actual decline in air flow depends on the fan curve, however, for the difference between a clean filter and the maximum pressure drop, it can easily amount …
