August 16, organized by the China Institute of Refrigeration Gree "distributed air supply technology in the heat pump air-conditioning research and application of" scientific and technological achievements assessment project will be held in Zhuhai, the Chinese Academy of Sciences Ho Yaling, China Household Electrical Appliances Research Institute Liu Ting, Tsinghua University Professor Li Xianting and other 9 industry experts unanimously found that the project achievements are the international initiative, the technology has reached the international advanced level. It is reported that this is the Gree Electric Appliances won the first 16 "international leader" finds. Gree Electric R & D personnel revealed that "indoor vertical temperature difference" is not a new problem, both domestic and foreign scientific research institutions and personnel have tried to try distributed air supply solution, but in the room heat pump air conditioning has been unsuccessful. In response to this long-standing problem for users, Chairman Dong Mingzhu a few years ago in the predictability of whether air conditioning can adjust the air supply to improve indoor vertical air temperature difference. "As a starting point, Gree R & D team Simulation in the laboratory to restore the indoor air flow and temperature field changes. Through several years of efforts, through thousands of calculations, experiments, the air conditioning fan, rectification, the end of the air supply and other technologies to improve, creatively developed a distributed air supply technology, and successfully applied to Gree air-conditioning products , Has been well received by consumers. Project research results Apply for 39 national invention patents, of which 8 apply for international patents. "At present, this technology has been realized in a new generation of Gree air-conditioning products," lead Royal "in the realization of the product. R & D personnel introduced the team through a series of technical solutions such as "Distributed Air Supply Terminal Technology Based on Thermal Comfort and Energy Saving", "Multi-Centrifugal Fan High-Efficiency Layout Technology" and "Multi-Fan High Efficiency and Low Noise Rectifying Technology" Air supply "technology successfully applied to the heat pump air conditioning, air conditioning to achieve a" carpet heating "more scientific and efficient air flow organization, a substantial reduction of the indoor vertical temperature difference, to solve the" hot and cold feet "problem , Give users a more comfortable experience. At the same time, this way of blowing air can make the heat act directly on the human activity area, reducing the heat generated by the accumulation of waste in the top of the room, saving electricity for the user. He Ya Ling, chairman of the project appraisal committee, said Gree has solved the key issues of poor comfort and low efficiency of the air flow in the heat pump air conditioner through a series of technological innovations. "The project team has done a lot of research and data comparison to prove that this is a very solid technical innovation." Project Evaluation Committee, Professor Ma Yitai Tianjin University, said heat pump air conditioning in the northern heating market prospects, "In 2016, Gree three-cylinder two-stage variable capacity compressor to solve the problem of air conditioning heating capacity, today, Gree distributed delivery The wind system application solves the problem of air-conditioning airflow organization.The combination of the two technologies has formed the perfect solution for the heat pump air-conditioning heating system, greatly expanded the application area of ​​the heat pump air-conditioning system, Great significance.
