Transcritical CO2 refrigeration, 100% green electricity, 180° free viewing angle, Cloud broadcast technology, discover the technical highlights of the upcoming Beijing 2022 Winter Olympics.
To help deliver a “green” Winter Olympics, refrigerant used at ice hockey and curling venues achieves a 65% reduction in global warming potential (GWP) in a cost-effective and energy-efficient way, a the refrigerant manufacturer told the Global Times on Friday.
In order to make Beijing Winter Olympics venues more environmentally friendly and sustainable, the Beijing Olympics Organizing Committee held talks with refrigeration industry experts at home and abroad. abroad before selecting two refrigeration systems for ice cream, conventional cooling systems with environment-friendly refrigerants and CO2 refrigeration systems.
Arthur Sutherland, an International Olympic Committee (IOC) ice expert, said the two systems are used on nine ice shields at the seven new or renovated ice venues, ThePaper.cn reported.
US chemical company Chemours is supplying coolant for four ice caps used at three sites to provide stable low temperature conditions.
The refrigerant is a hydrofluoroolefin (HFO) blend that has zero ozone depletion potential (ODP), lower GWP and high performance, the company has learned from the Global Times.
“Compared to previously used hydrofluorocarbon (HFC) refrigerants, it achieves approximately 65% reduction in GWP and up to 12% reduction in energy consumption,” said Michael Zhou, Asia-Pacific Commercial Director of Chemours Thermal & Specialized Solutions (TSS), at the Global Times. Friday.
Changing function is another consideration for venues as the renovations were not intended to convert them to permanent rinks, but rather to allow them to easily and quickly switch between “ice arenas” and “iceless arenas” according to different sports and cultures. ongoing programs.
The Beijing National Aquatics Center, Beijing National Indoor Stadium and Wukesong Sports Center, used as the main venues for the 2008 Summer Olympics, host men’s and women’s ice hockey and curling matches during the Olympics winter of 2022.
“The chillers have demonstrated their ability to meet high ice quality requirements and have proven suitable for converting facilities for different events,” Zhou said.
Five other ice shields that use CO2 refrigeration systems also exhibit zero ODP and low GWP. According to Sutherland, refrigeration systems are 30% more energy efficient and save around 2 million kilowatt hours of electricity annually compared to traditional cooling methods, ThePaper.cn reported.
In 2021, China decided to accept the Kigali Amendment to the Montreal Protocol to reduce coal consumption.
“We are seeing increased market demand and a more urgent need for high quality, low GWP alternatives. We are committed to contributing to optimizing the structure of China’s refrigerant industry and energy structure,” Zhou said.
