Carbon dioxide transboundary direct cooling ice making system
Ice making is fast and environmentally friendly
Carbon dioxide transboundary direct cooling ice making system is currently the most advanced, environmentally friendly and efficient ice making technology in the world. During the Beijing Winter Olympics, this ice-making system will ensure ice-making work at venues such as the National Speed Skating Hall, the Capital Gymnasium, and the Wukesong Sports Center.
Carbon dioxide cross-border direct cooling ice making system has two major characteristics, one is the fast ice making speed, and the other is the most environmentally friendly ice making process. In the ice making process, the system uses a sub-module control unit to divide the ice surface into different areas for ice making, so that the ice making effect is fast and uniform. In the case of the National Speed Skating Hall, it takes only 14 days to make all 12,000 square meters of ice surface, and the temperature difference between the ice surface does not exceed plus or minus 0.5 °C. The smaller the temperature difference on the ice surface, the better the flatness and stability of the ice surface, and the more conducive it is to the athlete to create good results.
Of course, environmental protection is more important. Compared with traditional methods such as carbon dioxide and refrigerants, this system not only emits less greenhouse gas emissions when making ice, but also improves energy efficiency by more than 20%. At the same time, the carbon emissions are close to zero, because it can recycle the waste heat energy in the ice making process and use it for dehumidification, ice repair and domestic hot water heating of the venue. This only one national speed skating hall can save more than two million kWh of electricity a year, and the Capital Gymnasium can save more than one million kWh of electricity every year, which truly achieves green environmental protection and is fully in line with the concept of greening and sustainability of the Beijing Winter Olympic Games.
Sports integrated training environment wind tunnel
Help athletes find the best posture
As a sports comprehensive training wind tunnel specially built for the Beijing Winter Olympic Games, it can accurately study the influence of wind on competition performance. Specifically, through the wind tunnel test, adjust and optimize the sports posture to reduce the resistance of the wind and air resistance during exercise, and then improve the performance of the movement.
For snow and ice projects, reducing air resistance is critical. Generally speaking, if the air resistance is reduced by 10%, the athlete's performance can be improved by 1%, and the wind tunnel of the sports comprehensive training environment is the best embodiment of scientific guidance training.
First, the device can create a variety of different speeds of wind, simulating the real speed and environment during sports and competitions. The simulated maximum wind speed can reach 42m per second, which is equivalent to the situation of a 14-level typhoon in life, so the wind tunnel of the sports comprehensive training environment can cover all ice and snow events, so it can be widely used in the wind tunnel test of ice competition and snow competition.
Secondly, the device also has a wind tunnel auxiliary training system for ice and snow projects, which can test how much wind resistance athletes can withstand. During testing, the system can feedback wind speed, wind resistance, attitude, center of gravity position, and test instructions to athletes and coaching teams in real time through a projector. Then through a series of wind tunnel tests and data analysis, find out the least resistance of the movement posture, so that athletes can know what kind of best posture they should maintain in sports.
In addition to optimizing the sports posture, this set of equipment can also slow down and optimize the queue of multiple projects; at the same time, it can also evaluate the richness of sports clothing and sports equipment, assist in the research and development of high-performance sports equipment, and help sports teams and athletes achieve good results to the greatest extent.
