August 28, 2017 Guangdong Provincial Light Industry Federation publicized the 2017 Guangdong Provincial Light Industry Federation Award for Science and Technology Progress Award, Guangdong CDC Intelligent Environmental Technology Co., Ltd., Shunde Polytechnic, Zhejiang Dunan Machinery Co., Ltd., Huazhong The project of "R & D and industrialization of high energy efficient DC-DC heat pump water heater system in low temperature and high humidity area" jointly won by the University of Science and Technology won the "First Prize" of Guangdong Provincial Light Industry Federation for Science and Technology Progress Award. VKIN in the whole DC inverter low temperature heat pump products innovation breakthrough light industry received a high degree of recognition.
The scientific and technological achievements of "The R & D and Industrialization of High-energy-efficient DCDC Heat Pump Water Heater System in Low-temperature and High-humidity Area" applied by CD-iMIC successfully passed the scientific and technological achievements appraisal organized by China Light Industry Federation. The three key innovative technologies are as follows: 1 Optimized combination of internal toothed tube evaporator and condenser to achieve phase change heat transfer process and the internal thread to optimize the matching tooth structure. Proposed a compressor frequency adjustment optimization method, developed a full control system operating conditions efficient. The feedforward compressor torque control method is developed to solve the vibration problem of the compressor in low frequency operation. The overall achievement of the project reached the international advanced level.
The achievement passed the provincial and ministerial level scientific and technological achievements appraisal, reaffirmed the only gold smart environment in the whole DC inverter air source heat pump technology innovation continued unremitting efforts, which also marks the only gold smart environment again in the full DC inverter heat pump Technological innovation in the forefront of the industry.
