1 mmWC = 9.81Pa. industrial process instruments and controls: tel: 1-925-706-7433 fax: 1-925-706-2583 Both static and total efficiency can be calculated from fan performance data as follows: Fig 1: FEG Formula. ): Velocity Pressure: Flowrate (CFM): Cross Sectional Flow Area (sq. wg. Fans fall … Let us assume a fan having a flow of volume 16m3/sec and devlops a total pressure of 500 mmH2O. This means the marketplace will determine what fan competitors do to boost efficiency while DOE will dictate the maximum power allowed, driving engineer specifications to demand higher efficiency either with a larger fan or a more aerodynamic shape. Despite all the textbooks and handbooks, which describe the proper procedure for selection of fans, practice shows that fans in existing HVAC systems have very low total efficiency. wg BHP = Fan power input, hp Static and total fan efficiency (Figure 1) can be plotted along with the fan curve. Other rules choose representative test conditions, which provide a fair indicator of a product’s relative efficiency during operation. It is a measure of the total mechanical energy added to the air by the fan. Thanks! FANS AND BLOWERS Bureau of Energy Efficiency 87 6.1 Introduction This section describes the method of testing a fan installed on site in order to determine the performance of the fan in conjunction with the system to which it is connected. ISO 12759:2010 specifies requirements for classification of fan efficiency for all fan types driven by motors with an electrical input power range from 0,125 kW to 500 kW. Minimize the negative financial impact on small-business manufacturers and customers, Facilitate prescriptive efficiency rebates that are effective and easy to administer, Belt-drive centrifugal-powered roof ventilators: 35% of selections, Belt-drive axial-powered roof ventilators: 50% of selections, Belt-drive in-line centrifugal and mixed-flow fans: 40% of selections. Click here to take a four-week course on commercial and industrial fan efficiency. Page Static Fan Efficiency = Volume (m3/s) * Pressure gain (Pa) / Power input (W) * 100. BHP = Fan power input, hp. where: LW= sound power level (dB) KW= specific sound power level depending on the type of fan (see Fig 9-3), from empirical data provided by fan manufacturer Q = volume flow rate (cfm) P = total pressure (inches of H20) BFI = Blade Frequency … CAN ANYBODY SHARE THE HOW TO DERIVE FAN EFFICIENCY FORMULA. But, if the pressure is measured in mmWC instead of Pascals and Power is expressed in kW, the formula can be derived as follows;-. In both the cases the power is same , I dont think there is any confusions now. Both a larger fan and a better aerodynamic shape have cost and strategic implications to fan manufacturers and their customers. That is why the DOE regulatory standard must be applied to any and all operating conditions. 12 issues of the leading cement industry magazine, your choice of complimentary handbook, plus unlimited access to CemNet.com News, Articles and HD Videos. This should also include the velocity pressure on the inlet side (if known) that is constant and in-line with the fan. Fans use approximately 40% of all electricity in HVAC systems. This represented 46% of the United States market in the regulated range. 6.2 Purpose of the Performance Test As explained by Ted ,I am only showing you an example for calculation in both the units and I hope you doubt will be clear. Typical ranges of fan efficiencies are given in Table 5.2. New fan-efficiency metrics developed by AMCA International—fan energy index (FEI) and fan electrical power (FEP)—can be used to right-size fans and reduce power consumption in commercial and industrial air systems. Online education: Fan Efficiency: Lowering Fan Energy Use, Regulation of commercial, industrial fan efficiency, Multi-family housing design trends driven by COVID-19, Consulting-Specifying Engineer most-viewed articles, November 2020, Ask an expert: Justin Garner provides input on COVID-19, Virtual reality challenges, solutions for A/E firms, Weekly merger and acquisition update: November 27, 2020, Designing, retrofitting hospitals during COVID: Sustainability. of The factor of 102 is used to convert mmWC into pascals because the formula for the static fan efficiency in SI units is;-, Static Fan Efficiency =  Volume (m3/s) * Pressure gain (Pa) /  Power input (W) * 100, But, if the pressure is measured in mmWC instead of Pascals and Power is expressed in kW, the formula can be derived as follows;-, Therefore 1Pa = 1/9.81 = 0.102 mmWC  (or, divide mmWC by 0.102 to get Pa), So, Static Fan Efficiency =  [Volume (m3/s) * Pressure gain (mmWC) / 0.102] /  [Power input (kW) * 1000] * 100, or  Static Fan Efficiency = [Volume (m3/s) * Pressure gain (mmWC)]  /  [Power input (kW) * 1000 * 0.102] *100, or  Static Fan Efficiency = [Volume (m3/s) * Pressure gain (mmWC)] *100 /  [Power input (kW) * 102], efficiency = m3/s X 0.102 mmwc *100/( motor kw x motoe eff.). H2O) Round Duct Equivelent of Rectangular Duct: Fan Total Efficiency = Motor Efficiency * Fan Efficiency, so you can adjust your fan total efficiency accordingly if you know the change in motor efficiency. Under the terms sheet resulting from a public DOE-sponsored Appliance Standards Rulemaking Federal Advisory Committee (ASRAC) negotiation, the DOE is expected to adopt a new fan-efficiency metric called a fan energy index, or FEI. The sound power produced by centrifugal and axial fans can be approximated by a simple equation (ref. A fan with variable speed must still comply with the design-point FEP requirements. It can be found by multiplying the Mechanical efficiency by the ratio of the fan static pres-sure to the fan total pressure. In other words, the DOE will regulate based on FEP at the design point only (full speed), but may authorize the use of an inflated FEI in marketing materials and product labels that benefit from variable-speed control. Certification of fan performance also must be done at any and all operating conditions offered for sale in the regulated range. The maximum fan shaft power allowed by DOE at the design point will be calculated in accordance with the following equation: No other DOE regulation is applied at all conceivable operating conditions. So, to use mmwc in the formula, you need to convert the mmwc into Pascals by dividing by 0.102. Efficiency is defined as the air power divided by the fan input power. Fans shall have a Fan Efficiency Grade (FEG) of 67 or higher based on manufacturers’ certified data, as defined by AMCA 205. Lets call the pressure measured in mmwc, Pmmwc. The peak total efficiency occurs at the top of the “bell” shaped efficiency curve. The fan efficiency formula is in SI units. While low-pressure fans use less power as they increase in diameter, it is impractical to drive low-pressure fans to become too large. Fan efficiencies differ from design to design and also by types. Efficiency advocates and AMCA jointly recommended that DOE establish target efficiencies such that the weighted average noncompliance rate of fan selections sold in 2012 is no greater than 25%, and the noncompliance rate of selections in the following categories does not exceed the values listed below: AMCA provided the Lawrence Berkeley National Lab-which analyzed data for the DOE-with a database of 1.3 million fan selections that were sold in 2012. The pressure and flow constants in the FEP formula correctly represent the actual map of efficiency degradation exhibited by the most efficient aerodynamic fans available as flows and pressures decline. The pressure constant increases the allowable power at lower pressure levels, recognizing the practical limitation of "zero efficiency at "zero" differential pressure. (Note that 0.2 plus a pressure constant of 0.4 equals 0.6, which is three times greater than 0.2.) The average total efficiency of all the fans was only 33% (Figure 1). ANSI/ASHRAE/IES 90.1-2013 requires fans have a fan-efficiency grade (FEG), as defined in AMCA 205, Energy Efficiency Classification for Fans, of 67 or higher. wg Pt = Total pressure, in. I TRIED A LOT BUT HOW 102 IS COMING IN DENOMINATOR ? Pt = Total pressure, in. If the wheel velocity is constant - the affinity laws for change in impeller diameter can be simplified to. Discuss how FEI is deterministically linked to projected energy savings, and how it can be used in specifications, codes, standards, and utility programs. The total efficiency of the fan at the design point of operation shall be within 15 percentage points of the maximum total efficiency of the fan. Search Products And Discover New Innovations In Your Industry!! Static efficiency is a ratio of the fan power output to the power supplied to the fan. Summarize the consensus recommendation that will guide the Department of Energy fan-efficiency rule. In such cases, the standard or minimum CFM to label a fan as an efficient one is considered to be 75. The terms sheet recommends a long list of exclusions, either because fan energy is already part of another DOE regulation, the fan application requires a design that compromises efficiency, or because the fan type is so rarely used that its aggregate energy use is trivial. In Sweden, ECiS AB (Energy Concept in Sweden) performed performance measurements of 767 fans in existing HVAC systems between the years 2005 and 2009. Fan efficiencies differ from design to design and also by types. He now consults on related questions with HVAC manufacturers and component suppliers. All fans offered for sale at operating conditions that require 1 to nominally 200 brake horsepower will be covered by the rule unless they are on an exclusion list. would be only 21%. Fig 2shows the pressures through a fan, each of which is described below: Inlet Pressure; is the static pressure on the inlet side of the fan. Fans consume about 18% of electricity purchased in commercial and industrial buildings. Fan efficiency metrics tend to be defined in terms of total pressure. Typical ranges of fan efficiencies are given in Table 5.2. Fan totalpressure is the total pressure (static pressure plus velocity pressure) at the fan outlet minus the total pressure at the fan inlet. Ps = Static pressure, in. AMCA expects that FEI ratings will become the most common description of fan efficiency in the marketplace, because FEI uses this FEP standard as defined in the first DOE rule as the benchmark against which fan efficiency will be compared forever. This peak efficiency is used to Since then, the AMCA worked to develop a consensus that was acceptable to fan manufacturers and efficiency advocates, which include the National Resource Defense Council, American Council for an Energy-Efficient Economy, Appliance Standards Awareness Project, Northeast Energy Efficiency Association, Southern California utilities, and others. FEGs are detailed in AMCA 205 and ISO 12749. Note that the flow and pressure constants in the FEP formula (250 cfm and 0.4-in. Most commercial fans also consume their initial cost in energy expense in less than 1 year. Here is another way to think of this: A fan running at 0.2-in. When you multiply fan area (square ft), fan speed (ft/s) and fan pressure (iwg), your units come out to be ft^3*iwg/s. A fan’s total efficiency is defined as the ratio of theoretical air horsepower (AHP) to the actual brake-horsepower (BHP) input to the fan shaft. The basic formula is a ratio of output to input expressed as a percentage: efficiency = (output / input) × 100. This new approach will be transformational to model codes and standards for energy efficiency including ASHRAE Standard 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings, ASHRAE Standard 189.1: Standard for the Design of High-Performance Green Buildings, and the International Energy Conservation Code. It is applicable to (bare shaft and driven) fans, as well as fans integrated into products. 6.5.3.1.3 Fan Efficiency. Search Products And Discover New Innovations In Your Industry. 1. The good news is that compliant fans are available in production today. and Total Efficiency can be calculated from fan performance data as follows: Where: CFM 3= Fan flow rate, ft /min Ps = Static pressure, in. Explain the proposed efficiency metrics of fan electrical power (FEP) and the fan energy index (FEI). While DOE will judge compliance strictly based on FEP (fan electrical power; electrical power supplied to the fan assembly), the DOE test standard will describe FEI as the ratio of the FEP standard (maximum power input allowed, as described above) over the FEP (actual power input) of the fan at its design point. Curing a noncompliant selection can be done with either a larger fan or a more aerodynamic design. For those outside the fan industry, this may seem like an unreasonable regulatory burden, but not so for those who make, rate, and sell fans. Fans integrated into products are measured as stand-alone fans. The pressure constant solves this issue. Rectangular Fin For cylindrical: Afin=πDL+ πD2 4 Join the community and register for a free guest account to post a reply. The flow constant produces a result that is similar to the FEG curves, recognizing that very small fans (and low flows) are less efficient due to the physics of airflow. The fan efficiency is the ratio between power transferred to airflow and the power used by the fan. Wade W. Smith led the DOE’s rulemaking negotiations for the fan industry. The fan efficiency is in general independent of the air density and can be expressed as: μ f = dp q / P (2) where. Regulating to raise actual fan operating efficiency would not be practical without these laws. That means that the regulation applies to an infinite set of conditions that define the particular design/selection points (airflows and pressure rises) offered for sale. DOE’s nomenclature is slightly different than in the white paper-DOE refers to FEI, which includes motor and drive losses, while the AMCA paper refers to fan-efficiency ratio (FER), which considers the fan only. Both the formulas are used in SI units and in general the work done theory the amount of air handle by a fan against a pressure is called work done and dividing workdone The final consensus vote showed support for a comprehensive terms sheet from all except two participants. Where: CFM = Fan flow rate, ft3/min. FEI is the ratio of the maximum power allowed by the DOE standard to the actual power of the fan selection at every (any) combination of airflow and pressure rise, rather than at a defined test point or points (such as peak efficiency used by FEG and FMEG or some other defined flow and pressure). By Wade W. Smith, PE, Wade W. Smith Consulting LLC, Chetek, Wis. Air Movement and Control Association International, Appliance Standards Rulemaking Federal Advisory Committee, ASHRAE Standard 90.1: Energy Standard for Buildings Except Low-Rise Residential Buildings, ASHRAE Standard 189.1: Standard for the Design of High-Performance Green Buildings, Air-Conditioning, Heating & Refrigeration Institute, National Electrical Manufacturers Association. The Fan Total Efficiency field (simply 'Fan Efficiency' in OpenStudio) will need to be adjusted to represent the change in motor efficiency and fan power consumed. The energy efficiency formula is based on energy output and input.energy efficiency = (energy output / energy input) × 100Energy output is the useful energy offered by an item such as the light generated by a light bulb. You are getting confusions for change in unit from mmH2O to Pascal. Rebate programs are likely to require DOE certification of FEP and compliance with the DOE test standard requirements. What this means is that for a fan handling standard atmospheric air with a density of 1.2 kg/m3 and a static efficiency of … To realize the potential efficiency of a fan, the fan must operate near its peak efficiency. ft.) Velocity Pressure (in. Definitions Efficiency, Hp, FP, Iac, Idc and Volts: E (Efficiency) = The efficiency of the motor is the ratio between the amount of mechanical work performed and the electrical energy consumed to do the job, represented by a percentage. Fans are ruled by well-ordered laws of physics, collectively called "the fan laws," which enable one to run a 20-minute fan lab test at one speed and accurately rate that fan and other larger fans at untested speeds. A higher percentage represents a more efficient engine. Note that the flow and pressure constants in the FEP formula (250 cfm and 0.4-in. We expect that the consensus terms sheet will guide DOE’s draft of fan-efficiency regulation, to be published very soon. The final rule will become mandatory 5 years after the final version is published However, DOE will invite manufacturers to use the DOE metric and test standard sooner and will accept certifications early (probably in 2017), so the engineers and utility rebate programs may begin to specify DOE-certified efficiency levels 3 to 4 years early. This ratio is 1.0 or greater for all compliant fan selections. Air Flow must be in m3/s, Pressure must be in Pascals, and Power must be in Watts. The Fan Laws are a group of useful equations for determining the effects of a change in the speed, the diameter of the fan and the density of air in the system. While fan efficiency varies with aerodynamic shape, under-sizing fans to reduce first cost has a stronger negative influence on fan efficiency. So, it should be;-1mmwc = 9.8 Pa or 1Pa = 0.102 mmwc. 1 They are most useful for determining the impact of extrapolating from a known fan performance to a desired performance. by time will give you the power. This renders the traditional regulatory approach ineffective. CalQlata has tried to keep the operation of this calculation option as simple as possible, given that it is recommended for general purpose calculations only and not for actual purchase specifications (see Fan Calculator – Technical Helpbelow). So, the peculiar nature of fan efficiency (which can be nearly anything, depending on conditions) comes with the blessing of fan laws that provide a means to deal with the challenge. The best forecast is that the target static efficiency for non-ducted fans will be 62% at the fan shaft, and the target total efficiency for ducted fans will be 68% at the fan shaft. Static Fan Efficiency (%): Brake Horsepower (HP): Air Density: Barometric Pressure (in Hg): Temperature (F) Density (lb/Cu.ft. Fans where the work per unit mass exceeds 25 kJ/kg. In other words, if the target efficiency in the DOE formula were 63%, the operating efficiency requirement for this selection at 0.2-in. dp1 / dp2 = (d1 / … We expect that the DOE regulation will require that FEI ratings must tie to FEP levels that are certified by the manufacturer to DOE. To convert this to horsepower, you need to divide by 6356. Consulting-Specifying Engineer published the first part in this series in June, which explained the peak-based metrics called fan-efficiency grade and fan motor efficiency grade (FEG and FMEG). Because the efficiency curve of a fan is bell shaped, specifying a relatively high FEG by itself will not necessarily result in high fan efficiency. of static pressure will be fan-power limited at a level that is three times greater than the target efficiency would indicate.
