This presentation explores the safety and cost benefits of a jet fan based car park ventilation system. The intended outcome of the presentation is the necessary understanding you need to evaluate new car park proposals, decide if a jet fan based ventilation system is most appropriate, and if so, prepare a specification against which a proposal may be prepared.

At a given rotational speed and fan pressure, centrifugal fans will develop a constant volume of airflow. Due to uncertainties in the final layout and construction of the ductwork, combined with the prospect of critical or changing process needs, many fans are selected to deliver more pressure and flow than what the industrial process or air-conditioning system actually requires. Some sort of control must then be employed to reduce the airflow to the desired level. In this self-guided course, you will explore common methods used for varying the flow capacity of the fan, such as speed control, outlet dampers, inlet dampers and inlet vane control. Your knowledge of these methods will allow you to accurately estimate and compare the power among the different methods. With this skill you can accurately predict the possible savings of changing to a more efficient method. Includes pdf course notes that are handy for future reference, and make it easier for you to follow along, especially if English is not your first language. Explore or re-visit topics in the sequence you desire. Learning activities and quiz questions keep you engaged in the topics. SI and IP units. Includes IP - SI spreadsheet calculator for unit conversion. Allow at least 2 hours in your schedule for completing this course. You can leave the course and the system will save your progress for when you come back.   Instructor: Ron Wroblewski  Course length: 2 hours  PDH credits: 2 Read more

The purpose of this presentation is to provide participants with an introduction to louvers and the different designs and components, as well as outline the parts of the overall system.

For building owners in Persian Gulf countries, sand storms have long been a fact of life and a threat to HVAC equipment. For this reason, there is growing global attention on the quantity of sand that moves through the louvers installed on building facades and casements of equipment penthouses and enclosures. But a great help has been introduced in this struggle against sand penetration, and that is the introduction of louvers specifically designed, tested and certified to reject sand. This presentation will cover the subject and assist engineers, architects, and specifiers in learning more about this important topic. This webinar was originally broadcast on February 24, 2021.

When selecting an exhaust system for a critical environment, there is an alternative to N+1 redundancy for critical systems. This system will provide significantly improved operating efficiency, smaller footprint, better control with faster response to changes, while allowing a lower upfront cost. What you would call a win-win situation! This webinar was originally broadcast on December 8, 2021.  Speakers: Doug Ross & Kristen Neath  Recording length: 60 minutes  PDH credits: 1   Read more
