Contract ENERGY MANAGEMENT, (ENERGY MANAGEMENT
CONTEACT, referred to as EMC, is a new energy-saving model successfully applied internationally based on market operation, and is a new energy-saving mechanism supported by the introduction of the United Nations。EMC contract energy management mode is an energy service contract signed by the energy saving service company and the customer (enterprise or institution), the customer pays a small amount of contract deposit, no need to invest any equipment renovation funds, and the energy saving service company provides the energy saving service to the customer in the way of promising the income of the energy saving project。Through this mode，The energy saving service company and the customer share the energy saving income generated after the implementation of the energy saving project，The energy-saving service company can gradually complete the cost and profit recovery of the implementation of energy-saving projects，Customers benefit by reducing current operating costs, such as operating electricity and maintenance costs，Both sides achieve win-win and rolling development。
EMC is not promoting products or technologies, but rather a financial management approach to reducing energy costs, essentially a way to pay for energy efficiency investments with reduced energy bills to cover the full cost of energy-saving projects。
Air compressor contract energy management，It's part of the energy management contract，Refers to a professional air compressor service provider，Provide energy-saving and efficient air compressor equipment and system optimization engineering services，Enable customers to obtain energy savings in electricity bills，To share the benefits of energy conservation，After a certain period，Air compressor service providers gradually realized the cost and profit recovery，An energy saving mechanism in which all energy saving equipment is transferred to the customer for free。

Use the first class energy efficiency air compressor to achieve EMC project energy saving
At present, most of the air compressors used on the market are energy efficiency marks two and three levels, and even some domestic assembly and assembly of higher energy consumption, choose a level 1 energy efficiency of the secondary compression Unax air compressor, energy saving market potential is huge。
The actual specific power is the only standard to measure the performance of air compressor。
For example, according to the national GB19153-2009 positive displacement air compressor energy efficiency limit value and energy efficiency grade standard, 250KW, 0.8MPa water-cooled air compressor, specific power of 1 level energy efficiency 5.7KW/M3/MIN, specific power of level 3 energy efficiency 7.5
KW/M3/MIN, the energy saving rate of grade 1 energy efficiency air compressor =1-5.7/7.5=24%
The simple theoretical calculation is as follows:
A foreign brand air compressor MM250, 250KW, service coefficient 1.15,8 barg, 42 displacement.5m3/min, full load operation 8000H a year, its annual gas capacity =
42.5 m3/min *60*8000H=20400000m3
Electricity for one year =250KW*1.15*8000H*0.8 yuan /KWH= 1.84 million yuan
Kaishan Air compressor UDT220-8, Grade 1 energy efficiency, 220KW, service factor 1.15, 8barg,
The displacement is 45m3/min, the same gas production is 20400000m3 a year, and the annual electricity cost is =220KW* 1.15=(20400000/45/60)*0.8 yuan /KWH)= 1.53 million It can be seen that, in theory, a year of energy efficiency of the Kaishan air compressor saves electricity = 184-153= 310,000, and the energy saving rate is about 17%。
Transformation of purification and drying process to achieve EMC project energy saving
This is mainly for the use of non-thermal regeneration adsorption dryer air compressor system energy saving scheme, the ordinary non-thermal regeneration dryer regeneration consumption of 15%, huge energy consumption。
Adsorption dryers use or recover the heat naturally generated during the compression process, and use this "free" heat for regeneration, consuming only 1% of compressed air
For example, supporting 250KW, 42.5m3/min air compressor
The annual electricity consumption of traditional dryers is：
6.375m3/min×6kW/(m3/min)×8000h× ￥0.8 / kwh= ￥244,800
The annual electricity consumption of the compression hot dryer is:
0.425m3/min×6kW/(m3/min)×8000h×￥0.8 / kwh= ￥16,320
1 year electricity savings =244800-16620=￥228180
