Improving air compressor efficiency is not just a trend anymore: it’s a competitive advantage in the world of growing energy costs and increasing accessibility of modern energy-saving technologies. Monitoring of air quality or compressor efficiency is often done through third party contractors on a periodic audit basis and this may be sufficient for a particular need but will always be limited by the length of time the survey gathered data from. To evaluate the performance of an existing compressor, the objective is to calculate the compressor efficiency (η) and power requirement. This will lead to errors of 10 to 30 percent. In the calculation adiabatic efficiency η ad is assumed to be equal to 0.76, and adiabatic k-value for air - 1.4. If the compressor efficiency is measured directly at the outlet as FAD, additional measurements downstream of the preparation plant will not only give an accurate picture of the losses or efficiency of the plant but also the raw volume and pressure delivered to the distribution system. The distribution of compressed air in industrial plants is prone to efficiency losses through pressure drops and leakage but the largest inefficiency is at the point of generation. So FAD is the amount of free air drawn into the compressor that is actually delivered by the air compressor at its compressed air outlet. Measuring the Free Air Delivery (FAD) of an air compressor can be challenging. • To calculate air pressure and temperature before and after compression process • To calculate indicated work/power • To obtain compressor efficiency • To calculate free air delivery rate (kg/s or m. 3 /s) The Analysis Objectives . Monitoring the electrical efficiency in isolation will not give a true picture of the compressor efficiency without considering the pressure and flow at the outlet. Leaks found in a facility’s air compressor system can waste up to 25 percent of compressed air costing, thousands of dollars in electricity per year. Air audits determine the actual air demand and evaluate the efficiency of use of compressed air in an operation. One … A few quick facts on air compressors and energy: Of the lifetime cost of an air compressor, 76% is electricity; An air compressor uses an electric motor or gas engine to take in air at one condition and release it at an increased pressure to power a range of industrial or commercial equipment.

The discharge flow of an air compressor contains air, water, oil and particles. The pressure drop across an air filter can reduce the intake air pressure by 1 to 3 percent. Compressor units are most commonly run with electrical induction motors driving piston or screw compressors. Others are not suitable because they cause a pressure drop, which in turn, leads to a waste of energy and money. A compressor has to compress 2000 m3/h of air (air volumetric flow at inlet conditions) at 6 bar g, from air at atmospheric pressure and 20°c. More information. There are a couple of parameters that affect the efficiency of air compressors. It's also very difficult to accurately use this estimated kW to calculate the percent of full load in the capacity-control cycle. It’s important to understand the operating flow at the air compressor discharge is made of two components: To measure the water contents precisely, it's required to measure the humidity in the pipe. The mechanical compression process is very inefficient with over 90% of the electrical energy lost as heat and noise. V - volume flow of compressed air at atmospheric pressure (cfm, ft 3 /min) k - adiabatic expansion coefficient. This article describes important terms related to the refrigeration & air conditioning compressors: compression ratio, compressor capacity or piston displacement, clearance volume and volumetric efficiency of the compressor. A screw compressor is available designed for air pressure boosting from P 1 =0.6 MPa to P 2 =1.8 MPa. Interestingly, when the humidity is set to a value between 80 to 99 percent, the measurement error is not more than ± 0.3%. Continuous monitoring of air quality can be achieved with modern sensors that can even be combined with the efficiency monitoring devices, such that a complete picture of the health and efficiency of the compressed air generation and distribution system can be evaluated for deviations from acceptable limits and managing operating costs. According to the U.S. Department of Energy compressed air systems consume around 10 to 30% of all energy of the average industrial facility. Measuring the Free Air Delivery (FAD) of an air compressor can be challenging. If you have had a compressed air assessment done at your plant, you will know the characteristics of your flow profile. More detailed analysis can follow from this to show the actual load cycles experienced by each compressor such that changing the control scheme could more effectively balance the loads across the compressor network. The ultimate job of an air compressor is to produce compressed air by sucking in ambient air, pressurizing or compressing it, and discharging it into the compressed air network. If you measure only amperes, you cannot know the power factor and the imbalances between the three phases. ... Air Compressor Calculations & Efficiency Formula. The efficiency of the compressor is known and is 0.72. Output of air compressor can be calculated in terms of free air discharge. The Benefits of Efficient Air Compressors. Known and measured properties are: a. For example, ISO 1217 relates to performance testing of displacement air compressors. Losses inside the air compressor, which cannot be measured. Compressors may be installed as individual units or more often, in groups with demand and standby control systems in place to respond to varying demand. The key to optimal air compressor efficiency is to maintain the integrity of your entire pneumatic system. Recently some manufacturers, especially from China, have introduced thermal mass flow meters to be installed at the intake side of the air compressor to determine the compressor performance. Also, air losses and control-air use increase with pressures within an air compressor so the compressor motor isn’t overloaded at higher pressures. It is intended for simple reciprocating (piston) air compressors.The running time you enter should be the total running time in a day the compressor is actually working. The compressor is to deliver 2000 Nm3/h of air. Of importance is what comes out and not what goes in! For example, the compression module in an 8-bar rotary screw compressor operates at a different speed than in a 10-bar machine. Measurement by section can isolate the largest leaks to target maintenance teams efforts. This includes the air compressor, fittings, air hose, and tools. Combined with regular leak surveys, these factors will allow you to enjoy a healthy and efficient compressed-air system. A dirty air intake filter can also vary the intake airflow by 2 to 3 percent. This calculator is very basic and calculates the total running hours, kWh used and electricity cost per year. There are several simple questions, which eventually explain the performance of an air compressor: To answer these questions, you may want to measure your air compressor on your own. A. An efficient pneumatic system will ensure that you’re getting the air … Cooling or heat reclamation systems can have an influence on the overall efficiency but it is still very costly to produce compressed air. Air Audits Find Inefficiencies. Minimal pressure drop, better no pressure drop. In many ways these flow meters beautify/exaggerate the performance because they do not consider: An air compressor user should insist on measurement at the outlet to determine the performance. To ensure everyone is talking about the same thing, industry and international standards have been written. Using this information, and the data taken from a CAGI data sheet, your compressed air auditor will likely be able to calculate the predicted operating cost of various types compressors and air dryers you choose to compare. When making decisions about energy efficiency, we need some accurate information to plug into power cost formulas.In past years, there has been a jumble of information based on a variety of test conditions. Based on the comparison, a pitot tube flow sensor stands out as the best choice for measurements at the compressor discharge. The types of flow meters allowed by ISO 1217 initially calculate a mass flow of air, which is then converted to an intake volume flow rate based on a value for the density of the air at the intake to the air compressor. Air compressor efficiency can be drastically reduced in a very short time when dirt, salt water mist, or similar air con taminants enter the inlet air. This article sheds some light on how to select the flow meter and summarizes parameters to be considered in the FAD measurement task. 3. To judge the performance of an air compressor, an on-site measurement is recommended. Standard condition gas volume flow rate (q S) or gas mass rate b. But first and foremost, its essential to understand that … Work required to compress the air isothermally to the actual work required to compress the air for the same pressure ratio B. Isothermal power to the shaft power or B.P. The intake humidity affects the amount of dry air delivered, but the error is less than other factors. Owning a machine that uses energy in an economical way is a goal that consumers in both the personal and professional realms share. Complicated installation and bulky equipment. It is vented (during blow down) to atmosphere when the air compressor unloads. Because air compressor manufacturers may state their FADs at different inlet conditions, it's advised to look into the air compressors data sheet and not just take the nameplate numbers! The discharge flow measured by a pitot tube flow sensor must be computed into FAD with additional measurements on the operating temperature and operating pressure. Compressor units are most commonly run with electrical induction motors driving piston or screw compressors. With a proper flow meter and some mathematics this task is manageable. Some processes may not reach peak demands during an audit that can skew the subsequent analysis and affect any changes implemented based on the survey. With a focus on Supply-Side Optimization, air compressor technologies and compressor control systems are profiled. Insertion-type flow meter suitable for temporary measurement. This is incorrect! In fact, 70 percent of all manufacturers use a compressed air system, for use with machine tools, material handling, as well as spray painting and separation equipment. Distribution losses through pressure drops and leakage further reduce the overall efficiency and optimisation of pressure reduction strategies combined with regular maintenance guided by leakage surveys can ensure that the compressed air system is as efficient as practically possible. Measuring air production at the compressor outlet can be difficult due to the very wet and possibly contaminated air present which can damage some sensors. Either way, knowledge of the electrical consumption for all the compressors will give a clear idea of the scale of the operating costs just to create the air. The primary components of a Oftentimes the true rate of an air compressor is misrepresented by manufacturers. Meanwhile, the air that an air compressor sucks in contains humidity (water vapor), and the air density (air per m3) changes with variation in the altitude, temperature and weather patterns. Pipe Velocity Calculator. “Actual volume flow rate of a compressor is the actual volume of gas, compressed and delivered at the standard discharge point, referred to conditions of total temperature, total pressure and composition prevailing at the standard inlet point.”.

[54] for low to high efficiency compressors. The goal of compressor sizing calculations is often to find out the efficiency of the compressor and power required to drive that compressor, given the gas composition, flow rate, temperature & pressure conditions at inlet and outlet pressure requirement. Contaminants will accumulate in the air compressor and reduce its compression efficiency. we need to calculate output of the air compressor. Measure Monitor Control is an independent specialist distributor of valve and instrument solutions. With a proper flow meter and some mathematics this task is manageable. FAD uses volumetric flow units such as m3/min and l/s etc. This is the actual volume of air delivered by the air compressor referred back to the conditions of the free air at the compressor inlet. Air used to “pump up” (pressurize) the air compressors internal volumes is measured as air delivered, but it's only stored within the air compressor. Fortunately, there is now a wealth of information about compressor and air dryer energy consumption available within the CAGI Compressor Data Sheets published by participating … Because of this, the only way to determine the real CFM of your air compressor is to test it yourself. Learn what you need to keep your air comrpessor systems running efficiently with our easy-to-use air compressor calculations and formulas tool.

This can be a centralised compressor plant or distributed compressors at key consumption points or a combination of both strategies. Let us discuss how to calculate FAD at shop floor. Air compressor power is defined by its power rating and the FAD specifications stated by the manufacturer when new. Some measuring methods fail because they cannot handle water and oil in the flow. The compressors' free output flow rate should cover this rate of air consumption. This is not an easy task, and you must take into account the almost- saturated-humidity conditions at high temperatures. These complex calculations can only be done using short-term data as the condition of the air compressor and its controls vary with time. While many plants use a degree of delivered air quality monitoring in accordance with ISO 8573 for dew point, oil and particles, extending the monitoring to include compressor and air preparation efficiency is straightforward.
