From Ice Arenas to Wind Tunnels: −271 to +230 °C Temperature Range in Binlun Environmental's Product Line

Binlun Environmental unifies under a single product line — from −271 to +230 °C and 0 to 90 MPa — commercial ice and snow arenas, wind tunnels for aviation engines, and controlled thermonuclear fusion laboratories.

Ice, Frost and Snow Technologies Conference

On November 7–8, 2026, the "International Conference on Ice, Frost and Snow Technologies 2026 and the Second Session of the First Convocation of the Working Commission on Ice, Frost and Snow Technologies of the Chinese Society of Refrigeration" was held in Beijing. The organizer was the Working Commission; the host was Beijing Institute of Technology. Participants included representatives from universities, research institutes, and companies from China and abroad.

Li Chao, Technical Director of the "Ice and Snow" division at Binlun Environmental, delivered a presentation titled "Smart Carbon Equipment for the Green Renewal of the Ice and Snow Industry." According to him, key directions include replacing traditional HFCs (hydrofluorocarbons) with natural refrigerants — ammonia and CO₂ (ODP = 0, GWP = 1), heat recovery from condensation, multi-energy "cooling–heating–electricity" systems, and intelligent energy-efficiency management.

Ice and Snow Arenas

In southern cities — Shenzhen, Guangzhou, Chengdu — indoor snow and ice complexes make skating available year-round. According to publicly available data, the indoor alpine skiing center in Qintian (Zhejiang Province) serves up to 200,000 visitors per year; the indoor ice arena of the "Zhonglv Wanke" children's sports center in Shenyang receives an average of more than 1,000 visitors per day. During the ice-and-snow tourism season, the "Ice and Snow World" in Harbin receives 47,100 visitors per day.

For retrofitting existing arenas in northeastern China, the company states that a systematic upgrade is required: "green cooling + energy-efficient heat pumps + intelligent management," which allows extending the operational period and reducing energy costs.

At the Capital Indoor Stadium (Jiutai Tiguang), where short-track speed skating and figure skating events were held at the 2022 Olympics, the rink zone is maintained at approximately 16 °C and relative humidity of about 35%. Binlun Environmental supplied a single-block magnetic-levitation centrifugal machine of high cooling capacity in combination with rotary adsorption dehumidification and direct evaporation in the air supply. Ice is produced using a CO₂ transcritical direct-cooling scheme; the heat extracted during the process is used for hot water supply for athletes and air dehumidification in the hall, which, according to the company, saves more than 1 million kWh of electricity per year. At the National Sliding Center, heat recovery from condensation through a water-source heat pump provides combined heating and cooling; the company claims energy efficiency 5–6 times higher than that of traditional electric heating.

Wind Tunnels and Research Laboratories

In 2019, Binlun Environmental signed a contract for the wind tunnel environment laboratory project for an aviation turbojet engine. Prior to this, according to the company, equipment in this niche was almost entirely supplied by foreign brands; in its words, the supply of full-cycle wind tunnel solutions allowed overcoming the technological barrier established by developed countries in the aerospace industry.

In the automotive segment, the company completed wind tunnel projects for the China Automotive Research and Technology Center (CAERI), GAC Honda, and Dongfeng Nissan. In the film "Pegasus 3" (《飞驰人生3》), the wind tunnel scene reflects real practice: every production model undergoes multiple tests for aerodynamic drag, aero-noise, and thermal management.

The company's products are applied in superconducting technologies, the aerospace industry, high-energy physics, controlled thermonuclear fusion, precision electromagnetic metrology, ultra-large accelerators, and cryogenic hydrogen liquefaction.

Product Line and Service

The range includes screw, centrifugal, reciprocating, and membrane compressors, absorption and industrial heat pumps. The operating temperature range is from −271 to +230 °C, pressure from 0 to 90 MPa. The company provides full-cycle services: design, integration, operation, and maintenance, designed for a system service life of decades.
