We always provide best control plan for central air-conditioner 

manufacturers. Our profound comprehension for refrigeration technics 

about its control and modulation rule as well as our creative research 

ability are often highly praised by same trade. Many of our innovative technical

fruit are wildly used by same profession, including as 

following:



Representative cases:

1) Control system: We spent three years cooperating with Dalian Iceberg 

    Group and finally exploit Hakawa units successfully (integrated unit 

    of heating, air-conditioner, and hot-water supply). This unit is 

    designed specially for family, and one unit can provide cool and heat 

    simultaneously with high efficiency.

2) Heat pump hot water unit, which we collaborated with many manufactures, 

    has run steadily in last 2 years.

3) Multiple compressor (two to four compressors) parallel connection 

    control system

4) Parallel connection compressor can not only reduce the cost of product 

    but also improve efficiency when under full load. Now we have two to 

    four compressors parallel connection control system which has worked 

    for about 3 years without failure.



We have special support in central air-conditioner trade and hope that we 

can cooperate with many more manufacturers to seeking mutual development.
