1. Frequency converter is used in air conditioning load class

Office buildings, shopping malls and some supermarkets and factories have central air conditioning, which consumes a lot of electricity during the summer peak. In hot weather, the electricity consumption of air conditioning in Beijing, Shanghai and Shenzhen all accounts for more than 40% of peak electricity. Therefore, the use of frequency conversion device, drag air conditioning system of refrigeration pump, cold water pump, fan is a very good power saving technology. At present, there are many companies specializing in air conditioning power saving, among which the main technology is frequency control power saving.

 

2. Frequency converter used in crusher class load

Metallurgical mines, building materials used in many crusher, ball mill, this kind of load after frequency conversion effect is remarkable.

 

3. Frequency converter is used in large kiln calcination furnace load

Metallurgy, building materials, caustic soda and other large industrial rotary kiln (converter) before most of the DC, commutator motor, slip motor, cascade speed regulation or intermediate frequency unit speed regulation. Because of these speed regulation modes or slip rings or low efficiency, in recent years, many units use frequency control, the effect is excellent.

 

4. Frequency converter is used in compressor type load

Compressors also belong to a wide range of applications. Low pressure compressor is widely used in various industrial sectors, high pressure large capacity compressor in iron and steel (such as oxygen machine), mines, fertilizer, ethylene are more applications. The use of frequency control, bring small starting current, power saving, optimize the service life of equipment and other advantages.
