From "not knowing the snow wax car" to creating "China's first snow wax car", this represents the highest level of Winter Olympic snow wax car manufactured in Shandong, and every place has undergone meticulous polishing by cutting-edge teams.
In November 2020, Haier received the need to cooperate with the provincial snow wax vehicle joint research team to carry out technical research.
The snow wax vehicle team of more than 200 people conducted technical research and development from three aspects: RV interaction design, fresh air system and air conditioning equipment.
The snow wax car is not so much a car as a new intelligent space tailored to the low-temperature environment and integrating a new generation of information technology, which is also the core intention of "intelligent manufacturing".
A 32-inch electronic screen standing next to the waxing table is the "wisdom hub" of the entire snow wax car. The electronic screen integrates the two functions of monitoring and control, monitoring air quality parameters, temperature, humidity, water heater, etc., not only so that all functions of the box can achieve one-button switch, such as vehicle photovoltaic, car air conditioning, etc., but also guide the waxer to match the snowboard with the most scientific wax type and grinding method.
Although this snow wax car is currently the world's largest single-layer unfolding area, the most integrated function of the snow wax car, but the air conditioning outside the machine can still use the space is still limited, which means that the parking air conditioning needs to be small in size, but also in the extremely cold environment, to maintain the excellent stability of efficient heating, only in this way can meet the strict work needs of athletes and logistics personnel.
Compared with the foreign upper exhaust scheme, the lower exhaust system of this snow wax truck optimizes the structure of the fan, shortens the air duct distance, can make it more suction, higher exhaust efficiency, and quickly suck away harmful substances produced during the waxing process.

"Don't underestimate the air conditioning system of this snow wax car, the doorway here is not simple." Fu Songhui, who is in charge of the snow wax car support service, said: "We need to pay special attention to multiple factors such as temperature fluctuations caused by frequent boarding and getting on and off the bus, and the filtration of dust generated during the waxing process, and provide solutions one by one. ”
In solving the problems of low temperature hot start and narrow installation environment in the car, Haier Air Conditioning has applied for a total of 6 new invention patents and applied 11 existing invention patents, which solves many problems such as low temperature hot start, narrow installation environment, and internal circulation of the temperature, humidity and fresh air in the process of keeping the athletes on and off at any time in the low temperature environment, providing a one-stop safe and reliable healthy air solution for the snow wax car.
At the same time, based on the customized design module of the COSMOPlat industrial Internet platform of Kaos, Kaos actively communicates with the Chinese national team coaching team, athletes, waxers and other on-site needs such as the use environment, installation environment, and use functions, and fully interacts with China National Heavy Duty Truck, the Provincial Design Institute, the Sports Group, etc., relying on the precipitated data power, simulation power, customization force and other capabilities, quickly develops and deploys the snow wax car interactive custom SaaS module, and uses digital twins and other technologies to quickly deduce the overall layout and functional partition of the snow wax car , while improving accuracy, the time required for the development of this first set of equipment was reduced by more than 60%.
In order to ensure that the extreme situation in winter is foolproof, the engineers of Haier Air Conditioning Xinjiang Company rushed to the scene within 12 hours after receiving the task, and at 3 o'clock in the morning, the engineers braved the low temperature of minus 20 degrees for debugging, and at the same time communicated remotely with the operators of the Kaos platform in Qingdao and Shanghai to ensure a one-time pass of the test.
In the end, which lasted 11 months, the team completed the entire process of design, research and development and manufacture of China's snow wax vehicles, breaking the monopoly of the ice and snow power on the snow wax vehicles, and handed over to the State General Administration of Sports by the Shandong Provincial Government.
It is reported that this snow wax car has applied for a total of 79 patents, including 22 invention patents, which is not only a key equipment to support the training and competition of the national team's ski projects, but also will serve the national team for a long time.
Haier Carrier: Carbon dioxide direct cold ice technology to produce "ice ribbon"
The carbon dioxide direct cooling ice project of the National Speed Skating Hall "Ice Ribbon", the main venue of the Beijing Winter Olympic Games, is provided by Qingdao Haier Carrier Refrigeration Equipment Co., Ltd. According to reports, this is by far the largest ice surface in Asia.
The use of carbon dioxide transcritical direct cold ice making technology, the first advantage is environmental protection. According to relevant experts, in the past, the ice making of the Winter Olympics was made of refrigerants such as Freon or ammonia, but Freon is easy to cause ozone layer destruction and global warming, and ammonia has the characteristics of being slightly toxic, flammable and explosive. The use of carbon dioxide to make ice not only brings the carbon emissions of the venue close to zero, but also controls the temperature difference between the ice surface of the venue within 0.5 degrees Celsius.
