Gree New Products Unveiled in China Refrigeration 2021

On April 7, the 32nd China Refrigeration Expo opened grandly in Shanghai New Int’l Expo Center.Gree showed his independent innovation achievements on HVAC, freezing and refrigeration, smart home and other fields in the expo. Meanwhile, Gree held the new product launch conference for 10kV high-voltage direct-driven permanent-magnet synchronous inverter centrifugal chiller and other products, representing the user-oriented innovation development of China’s HVAC industry on energy saving, intelligence and other aspects in the post-pandemic period with powerful strength.

At 10a.m., Gree officially launched his new product – 10kV high-voltage direct-driven permanent-magnet synchronous inverter centrifugal chiller in the booth. This product adopts permanent-magnet inverter driving technology, high-power 10kV high-speed permanent-magnet synchronous motor technology, high-speed motor direct-driven two-stage impeller, high-efficiency two-stage compression and air makeup technology, and other core technologies independently developed by Gree. It shows more excellent performance in energy saving and efficiency with single unit capacity up to 3000RT, over 40% energy saving than conventional centrifugal chiller. At the same time, this new product adopts the world’s first high-power 10kV high-speed permanent-magnet synchronous motor specialized for refrigeration centrifugal chiller, whose efficiency can reach 96% under full load and highest efficiency is up to 98.2%.

Liu Hua, president assistant and deputy chief engineer of Gree Electric Appliances, emphasized in his speech, “From technology, products to sales and service, Gree has always maintained a high momentum.” With continuous enthusiasm for independent innovation and core technologies made in China, Gree central air conditioners have served more than 100,000 projects worldwide, occupying the first market share in China for nine consecutive years and leading the industry development in construction energy utilization.

It is worth mentioning that Gree 10KV high-voltage direct-driven permanent-magnet synchronous inverter centrifugal chiller, Gree super high-efficiency permanent-magnet synchronous inverter screw chiller with variable volume and inverter scroll compressor for new energy bus were also awarded as “Innovative Products” of China Refrigeration Expo 2021 by the official expert committee of the expo.

In fact, affected by the pandemic, the entire HVAC industry was depressed in 2020. At this expo, Gree fully demonstrated its powerful R&D strength in large units, medical equipment, freezing and refrigeration, smart home and other fields, which also indicates that its supporting industry chains, such as molds, industrial products and IoT, gradually became mature.

As the leading enterprise in China’s HVAC industry, Gree Electric Appliances is committed to achieving the energy-saving technology progress of central air conditioners and boosting the systematic construction of HVAC industry.
