power-frequency compressor, and by 10% when compared with ordinary variable-frequency
compressor. The lower load ratio, the more obvious the energy-saving effect.
Leading constant pressure control
AVF permanent magnet variable frequency screw compressors can sustain the air supply at a pressure of 0.1 bar in any loading conditions. In case of larger demands for air supply, the compressor can increase rotation speed without changing the pressure to guarantee the air volume.In case of lower demands for air supply, the compressor can reduce its rotation speed without changing the pressure to meet such demands. In case of no demands for air supply, the compressowillil switch to sleep mode to saenergyray; when actual pressure achieves the wakening standard, the compressor will immediately start up with rapid response of frequency converters even in sleep mode.

Reduce energy costs
When the energy accounts for above 70% of the life cycle cost (LCC) of compressor, the energy consumption optimization becomes essential. In fact, the power consumption for the production of compressed air accounts for over 40% of the tota power consumption of the plant, so the energy consumption optimization can even determine its success. Using the permanent-magnetism frequency-conversion technology of Dresdnerlan, we can provide partners for your cost saving. WZs series of products can truly relect the demand for compressed air, making substantial energy saving become a reality.
raditionalcompressors are operated between two set pressure points using the control methods of “full load and
no load”The compressor turns into no load mode when the pressure reaches the maximum, When the air demand is
medium or low, the no-load power will be consumed excessively, which will result in large amount of waste.
Life Cycle Cost of Standard Compressors (LCc)
Because no unnecessarypower consumption willbe generated, the energy reduced Dv, the permanent-magnetism frequency-conversion can be up to 35% or more, The life cvcle cost (LCC) of the compressor can be reduced by an average of 22%.In a word, compared with the compressor with invariablerotatione speed, Wan Beardsley compressor can recover the extra cost within 1 or 2 years.
Life cycle cost (LCC) of Dresdnerlan Compressor
The long-term cost of owning and operating a compressor is composed of net asset value, installation, maintenance, and energy costsAdopting the Wan Beardsley Compressor solutiont can obtain a high return on investmenn.
Energy saving
Traditional compressors (standard machine) usually use ON / OFF or proportional requlation system, which adiusts the opening amount of the air inlet of compressor.
The adjustment method can also meet the actual requirements of the actual aas consumption. but the revolving speed of the compressor maintains at the rated speed in the entire adjustment process, the fictional work and cooling fluid aqitation work wil not
be reduced. the aas consumption is owered,the actual power consumption noT limitec substantialy, The variable freguency requlation can make the actual power consumption of the variable frequency compressor decline in the same proportion, and the energy is effectively used into the air compression.
Steady Pressure
It tracks system gas volume changes automatically, and
adjusts the revolving speed of compressor accurately with the
use of PID(proportional, differential, inteqral), to keep the
system pressure stable.
Start without stamping
The variable frequency starting method reduces the impact of
the start of the compressor on the power qrid and mechanica
parts greatly, thus extending the life of the machine.
In the market environment with fierce competition, it is an important matter as to whether the cost can be reduced. With the use of PM frequency conversion technology, you can save energy, thereby decreasing electricity expenditure sharply. It adjusts the compressor production capacity automatically according to the precise air demand, so you only need a minimum of energy. lhe energy saved is good for you and for the environment as wel.
Wan Beardsley products reduce energy costs in the following ways.
- Eliminate invalid transitional period from full-load power to no-load power
- Avoid excessive no-load power consumption
- Maintain the net pressure section
- Reduce the overall average operating pressure
- System pressure is low, making the system leak declined to a minimum
- It accelerates with the use of soft-start motor gradually, to improveflexibility, thus avoiding the surge
ENERGY-SAVING EFFECT
Similarly, for two models with above rated power 37kw, when load rate is only 605, input power ofpower-freguency model under ordinary air inflow throttling control is 39.2kw, while shaft power of permanentmagnetic power-freguency motor is 23,6kw with electricity saving ratio being 37.5%. If we calculate according to40,000 operating hours per year, annual electric charge of ordinary asynchronous power-frequency model is RiMB107.200, however, annual electric charge of permanent magnetic synchronous servo model is RB 65,800, savincRMB 41.400 in each year.
Difference of servo permanent magnetic variable-frequency technology andnon-variable frequency technology in energy conservation
Non variable-frequency unit regulates demand for air discharge with modulating capacity valve, whileservo permanent maqnetic variable-frequency unit requlates demand for air discharge in way of motol frequency conversion, and comparison of energy conservation between the two is as following:
Assumptions:
Average load is 70% (namely full-load time is 70%), it operates for 8,000 hours per year, unit electriccharge (KW/H) is RMB 0.7, power-frequency unit will be set according to general requirement, whenservo permanent magnetic variable-frequency unit reaches the lowesf rotating speed, o min is set asstandby status.
Energy-saving calculation: save least energy consumption under empty run + save energ)consumption needed during loading process + energy consumption under constant voltage
Compared with power-frecuency unit, amount of money saved by servo permanent maqneticvariable-frequency unit in each year is as seen in the following table:
Compared with the non-variable-frequency units, for servo permanent variable-frequency units, when aildischarge (%) is stabilized at 50%, the energy-saving proportion is about 23%. If the fluctuation of quantity demanded is more significant or air consumption (%) is lower, the energy-saving benefit will be more significant than 23%.
