On April 10th, this morning, the "Gold Award Product" of the 35th China Refrigeration Expo was officially unveiled at the China International Exhibition Center (Shunyi Pavilion) in Beijing.
Gree Electric Appliances' latest technological achievement, the "Ultra-efficient Dual-stage Permanent Magnet Variable Frequency Screw Chiller Unit," was awarded the 2024 "China Refrigeration Expo Gold Award Product." It stood out among nine gold award products, becoming the sole recipient of the "Annual Product" title.
Experts remarked that Gree's ultra-efficient dual-stage permanent magnet variable frequency screw chiller unit demonstrates significant technological advancements in development strategies, compressor mechanisms, rotor designs, and unit processes.
Achieving a world-leading performance level for medium and small chiller units, it represents the culmination of the enterprise's long-term technological accumulation and serves as a paradigm of independent brand-led technological innovation.
It is reported that Gree's ultra-efficient dual-stage permanent magnet variable frequency screw chiller unit has achieved a breakthrough in the energy efficiency level of small and medium cooling capacity chillers. The COP of the dual-head 400RT unit reaches 7.53, and the IPLV reaches 10.52, which is 29.9% higher than the first-class energy efficiency standard.
With its excellent cooling performance and comprehensive partial load performance, it can be widely used in various public buildings, rail transit, energy-saving renovations, and other fields, with enormous market potential.
According to the requirements of the "Green and Efficient Refrigeration Action Plan," by 2030, the market share of large public buildings and green and efficient refrigeration products should increase by more than 40%.
According to calculations, if 15% of existing building air conditioning units are replaced with Gree's dual-stage permanent magnet variable frequency screw chiller units, it could save 1.3 to 2.1 billion kWh of electricity, with comprehensive economic benefits saving over 1.4 to 2.5 billion CNY.
During this year's Two Sessions, Dong Mingzhu pointed out in an interview: "To develop new productive forces means to innovate, challenge, and break through. We must master core technologies, not stick to old ways, dare to take on social responsibilities, only then can we stand invincible."
