en.Wedoany.com Reported - In July, Haier Air Conditioning won three China Patent Awards and one National Science and Technology Progress Award, receiving two national-level science and technology honors within a week, showcasing its orientation toward technological innovation.
Haier takes user pain points as research topics. Addressing user complaints about harsh airflow from air conditioners, the Casarte Nebula cabinet air conditioner adopts a dual-tower structure and hollow air delivery design, combining air conditioner airflow, healthy airflow, and natural airflow to produce soft air, making the airflow more uniform and the experience more comfortable. This design won the Gold Award for Industrial Design in the Home Appliance category of the China Patent Award. To solve issues of poor cooling performance and high power consumption under high temperatures, Haier Air Conditioning uses a unidirectional shunt device and a variable shunt heat exchanger, allowing the heat exchanger to automatically match the optimal flow path based on cooling or heating modes, achieving faster cooling and lower power consumption. To address instability during low-frequency operation, Haier Air Conditioning invented a compressor speed fluctuation control method, improving operational stability under low loads. Both of these technologies won the China Patent Excellence Award.
National-level science and technology honors are important benchmarks for measuring technological prowess. Haier Air Conditioning first won an award in 1998 with its variable frequency multi-split technology, promoting energy efficiency in air conditioning; it won again in 2015 for its intelligent control technology for air conditioner comfort, addressing temperature fluctuation issues; in 2020, it won a third time for its key technologies in building thermal environment and green construction, advancing building energy efficiency; and in 2025, it won a fourth time for its precision brazing manufacturing technology, enhancing product durability. These four awards correspond to four key technological direction shifts in China's air conditioning industry.
Ultimately, technological achievements must translate into everyday user experiences. The precision brazing technology for which Haier Air Conditioning won the National Science and Technology Progress Award addresses the critical manufacturing issue of air conditioning pipeline welding. Welding quality directly determines the sealing reliability of the refrigeration system, affecting cooling performance and potentially leading to refrigerant leakage. Through material and technological innovation, Haier Air Conditioning has achieved zero leakage across tens of thousands of units, making the air conditioning products users receive more durable and reliable.
