I have worked for Siemens for almost a year and have learned more in this one video than I have almost all year. Good thing I was familiar with terminology and how things works/are. This is a outstanding video. 👍🏻👏🏻🤙🏻

@MEPAcademy Год назад

Thanks Garrett

@rahul-nm1kz Год назад

Can we have a quick call

@laynemaxson3411 3 месяца назад

Sounds about right, Siemens sucks with training and bringing their own people up.

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.

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

@MEPAcademy 4 месяца назад

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.

@andygiang6756 Год назад

Is there a program where I can click and drag blocks to form a sequence of operations?

@MEPAcademy Год назад

Yes of course. you could checkout Niagara Frame work by Tridium. they have a dog and drop feature with their visual programming tool called Niagara Workbench. Another example is the EasyIO line of controllers.

Are these courses for hvac control automation can some one tell me how to get into hvac autimation control

@MEPAcademy 3 дня назад

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.

@dwaynes5983 8 месяцев назад

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

@MEPAcademy 8 месяцев назад

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.
