      Yes, ASHRAE publishes a book titled "ASHRAE Guideline 36: High-Performance Sequences of Operation for HVAC Systems." This guideline provides standardized sequences of control for HVAC systems, focusing on improving energy efficiency, indoor air quality, and overall system performance in buildings.

    I have a question, My church has canvas ducting for the heat and air and is suspended from the ceiling. It seems to have a wire structure to support it... Im guessing... What is the proper name for that type of duct work? The registers are cut like a C shape that closes when its not running. I really appreciate any help

    In 20 min we went from a $0.50 switch to a $25k system just to turn a fan on off.

    • @MEPAcademy
      @MEPAcademy  Рік тому +3

      Correct, as it demonstrates the variability of solutions. Those in the controls industry know that there are ways to do things inexpensively, or with additional layers of controllability that add cost.

    • @Aquatic_Boys

      Energy managers need to be able to control that switch to save money. They will never recoup their initial investment but they can justify their job.

    • @gpower9129
      @gpower9129 26 днів тому

      25k is still cheaper than paying a human to stay in close proximity to a switch to turn it on&off at necessary times. Like the elevator operators of old, we found a more efficient way. 😁

    hello I want to know what is the difference between controlling AHU fan speed based on duct airflow or pressure differential?

    • @MEPAcademy
      @MEPAcademy  10 місяців тому

      There is no one simple answers as it is based on your application and the facility requirements. Controlling for air flow or CFM can be useful in constant volume application, while controlling for pressure can be useful in VAV applications by adjusting the fan speed with the use of a VFD. There may be critical applications that require that the Air Volume be maintained (Airflow based) and the fan speed is adjusted to maintain that CFM. In a VAV system, the pressure differential is closely related to the airflow. As the demand for conditioned air in the various zones changes, the pressure differential adjusts accordingly. Pressure-based control with a VFD allows the fan to operate at variable speeds, optimizing energy efficiency. The fan speed is increased or decreased as needed, reducing energy consumption during periods of lower demand.

    • @MEPAcademy
      @MEPAcademy  6 місяців тому

      If you're not already in the trade, then going to vocational school is a good start, or starting as an intern at a controls company if you have some mechanical background. If you have any form of a college degree or work history, then apply to control companies in your area, they are always looking for good people. Check your local college or vocational school for classes related to the HVAC industry or Building Automation Systems. Also, check all of the top control manufacturers websites for free training or certifications that could get you up to speed on the latest technology. Good Luck.

    I remember on a building automation project, i heard stories from an external mechanic working on a rooftop unit complaining about "why everything nowadays must be so complicated", referencing to an electrical duct heater that was supposed to have a modulating SCR on it instead of an on-off relay. First, I heard that this guy was terrible at its job and second, the reasons why are as explained here haha.
