AMCA COVID-19 Guidance for Large-Diameter Ceiling Fans

Numerous studies of airflow and performance characteristics of circulating fans have been undertaken. Relatively few, however, are focused on aerosol transmission of airborne pathogens in large industrial spaces, a shortage all the more noticeable during the coronavirus disease 2019 (COVID-19) pandemic. To contribute to and improve the body of COVID-19-prompted guidance for the operation of circulating fans, Air Movement and Control Association (AMCA) International commissioned numerical-simulation studies of airborne-particle and aerosol transmission with large-diameter (greater than 2.1 m [7 ft]) ceiling fans (LDCF). The focus of the studies was warehouses in the United States, in which LDCF commonly are used for comfort cooling and destratification. The results, however, also are applicable to many manufacturing/industrial facilities. Join us for an in-depth look at this study, the research team, study results and ongoing guidance. Due to the content of this webinar PDH credit is not available. This webinar was originally broadcast on January 5, 2022.

Advanced Affinity Laws

The performance of a fan is defined by the flow, fan pressure, and power draw of the fan. The fan affinity laws (also called the fan laws for short) are a set of inter-related equations that predict the performance of the fan under varying designs and conditions. For example, from a fan applications perspective, some fan laws dictate how the performance of the fan will vary if we change the density, or the rotational speed of the fan. From a fan design perspective, other fan laws can predict the change in performance due to changes in impeller diameter or size. Yet another even predicts the change in the noise generated by the fan.In this self-guided course, you will apply a simplified set of affinity laws to predict fan performance changes due to changes in rotational speed and changes in density compared to catalog conditions. In high-pressure systems (over 3000 Pa or 12 in w.g.) the compressibility factor must be calculated. Usually when the rotational speed or density changes, the compressibility factor also changes. In this course changes to the compressibility factor are fully considered, and a method from AMCA publication 210 for calculating the compressibility factor is presented.Included are .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.

Psychrometrics for Fan Systems

Psychrometrics is the study of the properties of mixtures of air and water vapor. A general knowledge of psychrometrics is very useful in fan application engineering, mainly because the performance of the fan is directly related to the density of the gas. Knowledge of psychrometric principles allows the fan application engineer to measure the amount of water vapor in the air, determine the density of the mixture, and thus accurately predict changes in fan performance. In this self-guided course, you will graphically explore psychrometric properties, such as dry bulb, wet-bulb, relative humidity, dew point, and humidity ratio as they are plotted on the psychrometric chart. Your knowledge of these properties will allow you to accurately calculate density and give you other skills useful in fan application engineering, such as the ability to predict whether condensation will occur in the system.

Fan System Control

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.

Calculating Flow Rate

After a performance test is completed, the data is used to calculate the fan parameters such as flow, fan static pressure, fan static efficiency fan total pressure, and so on. This self-guided course uses two completely separate avenues to teach the calculation method. In the first, you learn the calculations and their order by navigating your way through the problem, which is presented as a learning puzzle. We have fondly named it "the labyrinth" because as you navigate the challenge, you are exploring the relationships between the variables. In the second approach you approach the calculations in linear order and learn how to program them into a pre-formatted spreadsheet that you can use on future projects. The second approach is optional. 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.

Heat Recovery in Fan Systems

In many fan systems, the amount of electrical energy used to drive the motor is a small fraction of the thermal energy carried by the air or gas. When this thermal energy is wasted, or dumped to atmosphere, it can represent a huge opportunity for energy savings through heat recovery. In new commercial air conditioning applications where there is a high demand for outdoor air, recovering the "cool" energy in the air that is spilled is often immediately cost effective, without any payback period. Industrial thermal processes such as boilers, foundry dust exhaust, and steel mill ovens, (among others) are often great candidates for heat recovery. In this course you will be introduced to 5 different strategies for thermal energy recovery, including the use of: heat wheel, air-to-air, air-to-water, water-to-air, and glycol run-around heat recovery systems. The course also includes a method for estimating the potential energy savings, so you can see if the project has enough value to proceed with the design and implementation.

This self-guided course examines FEI as it applies to stand-alone fans. It describes the concepts behind FEI, advantages of FEI compared with the fan-efficiency-grade (FEG) metric it is replacing, how to use FEI to estimate lifetime fan energy savings, and methods for applying FEI in building codes and efficiency programs.
