Air compressor power consumption is very large reasons

It may be that your compressed air system is not well measured.

The ecosystem of building energy consumption includes a series of roles such as energy consumption users (enterprises, buildings) and energy managers. This has changed the simple monitoring and transformation mode in the field of energy saving in the past, and provided a more effective and continuous solution.

Since the installation of the compressed air device, the energy consumption data has been continuously collected, classified, sorted and analyzed to form an energy consumption analysis report for publicity, quota management or service basis for energy consumption users. The energy consumption administrator will feed back the information to the users, and professional service providers will provide energy-saving opinions to create energy-saving behavior for the whole people. This behavior needs to be continuously cycled until the energy consumption state reaches the best, realizing the all-round management from data collection, sorting to analysis and operation services.

Requirements for energy metering of compressed air installations

the user is responsible for the centralized control and remote management of the energy consumption equipment, the best control and schedule management functions of the equipment, and the simple data analysis and reporting functions of the compressed air monitoring and management platform. The operation monitoring page includes equipment monitoring and holograms. Hologram is to intuitively reflect the running state of the equipment to the floor plan of the building, and truly display the electronic map of the building, the operation information of each equipment, the running state and the running data.

With dynamic, complete and accurate energy consumption statistics, energy metering management can better determine the focus of equipment operation and energy saving, pay attention to the development and change trend, so as to guide the next energy-saving operation of equipment, and provide the basis and foundation for energy-saving planning and administrative management system.

Energy consumption includes total water consumption, total electricity consumption and total gas consumption trend. The total water consumption trend of the equipment is displayed according to different time scales such as day, week, month and year. Comparison of the total water consumption of the day and the water consumption of the previous day. Comparison of water consumption for the current day and the selected date. The chart of the total water use trend can be output as a report format. More accurate and refined management of the equipment under its jurisdiction.

Managers can implement the energy consumption sub-quotas for the operation of various types of public equipment and the comprehensive energy efficiency indicators of energy consumption subsystems at all levels by establishing an energy consumption quota management mechanism. The management platform carries out centralized dynamic monitoring and management of various indicators, observes the changes of various energy consumption conditions at all times, and constantly compares them with the energy consumption standards specified in the indicators, thus eliminating all kinds of energy consumption increases caused by negligence in management and operation. At the same time, equipment with the same function is compared horizontally and rewarded for energy consumption by operation items.

Energy Consumption Composition of Industrial Compressed Air

for virtually all industrial compressed air production, electricity is the primary energy source. In many compressed air installations, there is often considerable and useless energy, in order to provide possibilities, for example, by means of energy recovery, pressure reduction, leakage reduction and optimization of operation by selection of control and regulation systems. When planning a new investment, look as far into the future as possible, seeking to explore in depth the impact of the new situation and the possible requirements for the device.

These are very beneficial, typical examples are environmental protection requirements, energy saving requirements, the need to improve product quality and future production investment. Optimizing compressor operation is becoming increasingly important, especially in large industrial processes dominated by compressed air, where production changes over time. The operating conditions of the compressor will also change. Therefore, it is important to consider both when determining the compressed air source, not only to meet the existing actual needs, but also to plan for the future. Experience has shown that extensive and unpreconceived analysis of the form of application will improve the overall economy in any situation.

Ways to Reduce Energy Consumption of Compressor Unit

as far as the overall economy of the compressor plant is concerned, the cost of energy consumption is undoubtedly a key factor. Therefore, it is important to focus on finding solutions that meet the requirements of performance and quality and the need to make full use of energy. To do a good investment plan, it is also necessary to clarify the additional costs to the compressor and other equipment in order to meet these two requirements. Since energy consumption usually accounts for 80% of the total cost, care should be taken when choosing a regulating system. The difference in the regulation system makes the difference between the compressor types, and the ideal situation is that the total gas volume of the compressor just meets the needs of the gas equipment. Most compressors are supplied together with the control and regulation system, so having an additional regulation and control device in one unit to jointly control several compressors will further improve the operating economy.

Since the power required is actually proportional to the rotational speed when the energy is changed, rotational speed regulation is becoming a commonly used regulation method, and good results will be obtained by carefully considering and determining the choice of regulating equipment according to the needs. If only a small amount of compressed air is needed at night or on weekends, it will be beneficial to install a small compressor to meet the needs. When, for some reason, another working pressure is required, this should be analyzed to see if all production can be met with one compressor center, or if it is necessary to divide the network into different pressure levels. As some departments are closed at night and on weekends, when choosing a compressed air network, it may be discussed whether to reduce the air volume or to share the cost internally based on the measurement of the flow.

Investment costs are fixed costs, consisting of equipment procurement costs, construction costs, installation and commissioning costs. As part of the total cost, the investment cost is partly related to the quality of the compressed air selected and partly related to the apportioned payback period and the calculated interest rate. The magnitude of energy costs is linked to factors such as annual operating time, degree of utilization, and energy prices. Certain cost-sharing, such as energy recovery equipment, is billed directly, reducing operating and maintenance costs.

When calculating the power demand, it is important to keep the total power demand in mind. The energy consumption of each part of the equipment itself should be carefully analyzed, such as the intake filter, fan and water pump, cooling tower fan, and circulating water pump. When comparing different investment scenarios, it is particularly important to use comparable data. It must therefore be ensured that the values used are consistent with the local energy consumption measurement. The change of working pressure will also directly affect the power demand. High pressure indicates high energy consumption. Increasing working pressure to compensate for pressure drop will eventually damage the economy of operation. Despite this, it is currently a common method, for example to overcome the pressure drop caused by too small a pipe network diameter and filter clogging. Increasing the operating pressure by 0.1MPa results in an increase in power demand of nearly 6%. A device with several filters, especially if the long-term operation is not replaced, the pressure drop will be significantly increased, so the cost is significantly increased.

Reduce the loss of ineffective energy consumption caused by leakage

by analyzing the route and use of compressed air, we can find a way to make the load in the compressed air system more balanced. Therefore, it is necessary to increase the control production and reduce the operation cost. The useless consumption is often caused by leakage, equipment wear, process mismatch or improper use of compressed air. It is best to correct it through continuous and comprehensive observation. The compressed air system can be divided into several zones and supplied with valves respectively, which can reduce the air consumption during night shifts or weekends.

In most devices, there will be some degree of leakage, which is a net loss, which must be reduced to a minimum, sometimes the leakage loss can reach 10%-15% of the compressed air production, or even more. Leakage is proportional to the working pressure, so repairing the leaking equipment and reducing the working pressure is a way to reduce leakage. For example, the working pressure is only reduced by 0.03MPa at night, and the leakage can be reduced by nearly 4%. If a 100 m3/min compressor device leaks 12%, the working pressure is reduced by 0.03MPa, and the energy saving can reach 3KW · h/h, which is equivalent to the electricity consumption of a standard household.

In short, the energy metering management of air compression system is mainly based on the energy consumption of electric energy, which can be analyzed through cost analysis and energy consumption cost allocation. From the perspective of management, it is necessary to analyze and control many aspects from the early investment plan, equipment procurement and installation, equipment operation and maintenance, so as to reduce the leakage of invalid compressed air and reduce the consumption of invalid energy. This will truly put the energy management system on the basis of the ecosystem of social building energy consumption.
