The Growing Pains of the Industry Amid the Ice and Snow BoomWith the deepening of the *"Engaging 300 Million People in Ice and Snow Sports"* initiative, the ice and snow industry has long broken through the limitations of season and geography, and indoor ice and snow venues have become the core carrier of national ice and snow consumption and industrial development in China. From ice and snow parks in southern commercial complexes to professional competition and training venues, the demand for the construction of indoor ice and snow venues continues to surge. However, the industry has always been constrained by three core challenges: the persistently high energy consumption of traditional refrigeration technology leading to soaring operating costs; the environmental risks of Freon refrigerants running counter to China’s "dual carbon" goals; and insufficient ice surface temperature control accuracy, which undermines the sliding experience and further aggravates energy waste.Against this backdrop, the digital and low-carbon transformation of indoor ice and snow venue construction has become an inevitable trend for the industry’s development. From the technical benchmark set by the "Ice Ribbon" of the Beijing Winter Olympics to the popularization of technology in commercial venues today, a digital revolution in the construction of ice and snow venues is in full swing.1. From 1.0 to 3.0: The Full Digital Evolution Process of Indoor Ice and Snow Venue ConstructionThe construction and development of indoor ice and snow venues in China have always been deeply bound to the iteration of digital technology, and have gone through three core development stages as a whole:1.0 Extensive Initial Stage (2000-2010): Manual-led Operation with Zero DigitalizationIn this stage, the number of indoor ice and snow venues in China was scarce, mainly concentrated in core cities in northern China, dominated by small ice rinks. The construction mode completely relied on manual experience and traditional technology, and the refrigeration system adopted the traditional Freon indirect refrigeration scheme. Equipment operation and maintenance, ice surface maintenance, and temperature regulation all relied on manual inspection and manual operation, without any digital monitoring capability. This resulted in large ice surface temperature differences, high energy consumption, and high equipment failure rates, and the refrigerants caused significant damage to the ozone layer. The industry as a whole was in an extensive development state of "small, scattered and weak", with an almost zero level of digitalization.2.0 Standardized Development Stage (2011-2022): Standardized Electromechanical Systems with Initial DigitalizationBeijing’s successful bid for the 2022 Winter Olympics in 2015 became a key turning point for the industry’s development. Indoor ice and snow venues ushered in explosive growth, the southern market rose rapidly, and the construction mode gradually became standardized and normalized. Mature construction standards were formed for refrigeration systems, snowmaking equipment, and venue infrastructure. Some venues began to introduce basic automatic control systems to realize digital monitoring of temperature and equipment operation status. However, digitalization in this stage was still limited to "data viewing", unable to realize intelligent control and system coordination. The pain points of energy consumption and environmental protection of traditional refrigeration schemes had not been fundamentally solved, and most venues still faced the operating dilemma of "affordable to build, but unaffordable to operate". 3.0 Digital Intelligence Stage (2023-Present): Full-link Digitalization with Low-carbon IntegrationThe technology spillover effect of the Winter Olympics has pushed the industry into a new era of digital and intelligent construction in an all-round way. BIM digital twin, AI intelligent control, and green refrigeration technology have rapidly spread from Olympic venues to commercial venues. The construction of indoor ice and snow venues is no longer limited to "hardware construction", but has shifted to "full-life cycle digital management". Digital technology covers the whole process of the venue, from digital modeling in the design stage, to intelligent construction in the construction phase, and then to AI intelligent operation and maintenance, as well as energy and carbon dual control in the operation stage. Meanwhile, under the "dual carbon" goals, low-carbon and environmental protection has become a core indicator for venue construction, and the integration of green refrigeration technology and digital intelligent control has become the core development direction of this stage.2. The Core of Industry Breakthrough: Overcoming the Two Key Pain Points of High Energy Consumption and Environmental ProtectionThroughout the evolution of the industry, the core bottlenecks restricting the high-quality development of indoor ice and snow venues have always been the two major challenges of energy consumption and environmental protection.Data shows that the energy consumption of the refrigeration system in traditional indoor ice and snow venues accounts for more than 60% of the total operating energy consumption of the venue. The traditional ethylene glycol indirect refrigeration system not only has low heat exchange efficiency and high comprehensive energy consumption, but also uses Freon refrigerants with high Ozone Depletion Potential (ODP) and extremely high Global Warming Potential (GWP), which is seriously inconsistent with global ecological security and China’s "dual carbon" goals.At the same time, the traditional temperature control mode cannot accurately respond to the real-time changes of passenger flow, ambient temperature and humidity, and ice surface heat load in the venue, and can only operate with fixed parameters set manually. This will not only lead to excessive temperature difference on the ice surface, affecting ice quality and sliding experience, but also cause a large amount of invalid energy consumption, further increasing the operating cost pressure of the venue.To achieve the sustainable development of the industry, a fundamental breakthrough must be made from the two dimensions of the underlying innovation of refrigeration technology and the digital upgrading of temperature control mode. This is exactly the core direction that Yangsheng Ice & Snow has been focusing on and tackling through continuous research and development, with its deep roots in the field of indoor ice and snow venue construction.3. Yangsheng Ice & Snow Technical Solution: CO₂ Refrigeration System + AI Algorithm Temperature Control, Dual-wheel Drive to Restructure Industry StandardsBased on in-depth insight into industry pain points and years of technical precipitation, Yangsheng Ice & Snow officially launched an integrated solution of **CO₂ transcritical direct refrigeration system + AI algorithm intelligent temperature control** tailor-made for indoor ice and snow venues. Rooted in environmental protection technology and centered on digital capabilities, it completely solves the three core problems of the industry: energy consumption, environmental protection and temperature control, and redefines the construction standards of indoor ice and snow venues.1. CO₂ Transcritical Direct Refrigeration System: Green, Environmentally Friendly and Extremely Energy-efficientAs the most advanced green refrigeration technology in the current ice and snow venue field, Yangsheng Ice & Snow’s CO₂ refrigeration system uses natural working fluid carbon dioxide as the refrigerant, which fundamentally eliminates the environmental risks of traditional refrigerants: its Ozone Depletion Potential (ODP) is 0, Global Warming Potential (GWP) is only 1. It is odorless, non-flammable and non-combustion-supporting, with near-zero carbon emissions. It is a truly sustainable and environmentally friendly refrigerant, fully in line with the "dual carbon" development requirements.In terms of energy-saving performance, this system has achieved a leapfrog breakthrough. Different from the traditional indirect refrigeration scheme which causes a lot of energy loss through secondary heat exchange, Yangsheng Ice & Snow adopts transcritical direct refrigeration technology, allowing carbon dioxide to directly enter the ice surface cold exhaust pipes to complete heat exchange, which greatly improves the heat exchange efficiency and can reduce the overall energy consumption by more than 30% compared with traditional refrigeration systems.At the same time, the system is equipped with full heat recovery technology, which can fully recover the waste heat generated in the refrigeration process for venue ice pouring hot water, heating, dehumidification, domestic hot water and other scenarios, realizing the cascade utilization of energy, further reducing the comprehensive operating cost of the venue, and truly realizing "one machine for multiple purposes and maximum energy efficiency". In terms of ice surface quality, the system can accurately control the ice surface temperature difference within ±0.5℃, ensuring uniform hardness of the ice surface, which can not only meet the extreme requirements of professional competitions, but also provide high-quality guarantee for the public skiing experience. 2. AI Algorithm Intelligent Temperature Control: Digital "Super Brain" to Realize Full-scenario Precise ControlIf the CO₂ refrigeration system is the "green heart" of the venue, then the self-developed AI algorithm temperature control system of Yangsheng Ice & Snow is the digital "super brain" of the venue.This system is developed based on machine learning models and trained with massive operation data of ice and snow venues. Through a large number of sensors deployed on the ice surface, in the venue environment and on the refrigeration equipment, it collects multi-dimensional real-time data such as ice layer temperature, ambient temperature and humidity, equipment operation status, and passenger flow heat load at millisecond speed, to build a full-scenario digital twin model.Based on real-time data and pre-trained models, the AI algorithm can accurately predict the change trend of ice surface heat load in the next 1-24 hours. Without waiting for significant temperature fluctuations, it can issue control instructions to the refrigeration equipment in advance, dynamically adjust the carbon dioxide flow, equipment operating power and start-stop sequence, and realize "predictive control". Compared with the traditional manual fixed parameter operation mode, this AI temperature control system can further upgrade the control accuracy of ice surface temperature difference, greatly reduce the invalid start and stop of equipment, further reduce energy consumption, and extend the service life of the equipment.In addition, the system has realized the coordinated linkage of multiple systems such as venue refrigeration, snowmaking, dehumidification and energy recovery, supports real-time monitoring of energy consumption data, abnormal early warning, and visual statistics of carbon emissions, provides the venue operator with full-cycle digital operation and maintenance management capabilities, truly realizes the leap from "manual operation and maintenance" to "intelligent unattended operation and maintenance", and greatly reduces the operation and maintenance labor cost and management difficulty of the venue.4. Digitalization + Low-carbonization Defines the Future of Indoor Ice and Snow Venue ConstructionAt present, the ice and snow industry is in a critical window period of high-quality development. The construction of indoor ice and snow venues has long bid farewell to the extensive mode of "focusing on scale over operation", and digitalization, low-carbonization and intelligence have become an irreversible industry trend.Yangsheng Ice & Snow has always taken technological innovation as the core, and has been deeply engaged in the field of indoor ice and snow venue construction. The integrated solution of CO₂ refrigeration system + AI algorithm temperature control launched this time is not only the commercialization and upgrading of the green ice and snow technology of the Winter Olympics, but also provides a replicable, cost-effective full-chain technical solution for the construction and operation of indoor ice and snow venues in China.From design and construction to operation and maintenance, from low-carbon environmental protection to cost reduction and efficiency increase, Yangsheng Ice & Snow is taking digital technology as the pen and green innovation as the ink, promoting the construction industry of indoor ice and snow venues in China to enter a new stage of development, allowing more people to feel the charm of ice and snow sports in high-quality indoor ice and snow venues with constant temperature all year round, and helping the sustainable and high-quality development of China's ice and snow industry.---**Enquiry Hotline**: +86 13691511384**Company Address**: Room 603, Building 10, Yuanda Science and Technology Park, Shunyi District, Beijing, P.R.
