Innovation

Vaqoung has established a provincial R&D center in 2004 which have 60 staff in total. The R&D center have strong ability in research and design of different type vehicle air conditioners and electric scroll compressors. A rigorous development system has been created gradually, and all the developed products have proprietary intellectual property tights.

The core team of Vaqoung R&D center consists of senior engineers who has 20 years’ experience in A/C scroll compressor and HVAC area. This team mastered the design theory of electric drive scroll type compressor like calculation and design of scroll profiles, design of scroll compressors’ structure, calculation of static and dynamic equilibrium, calculation of hydrodynamics. The R&D team also have engineers who are proficient at manufacturing technology like mechanical treatment, assembly process management, measure and experiment, project management and process control etc.

Vaqoung have a lot of technical cooperation with Beijing Institute of Technology, Hunan University, Central South University and established Electric Vehicle Air Conditioner engineering center with Beijing Institute of Technology for a deep research of economic air conditioners and A/C scroll compressors for EV. The information exchanging with China famous Universities confirms Vaqoung’s product R&D keeps in step with the world’s leading level HVAC technology.
