Recently, Xu Yong, president of commercial HVAC in Trane China, said in an interview that data shows that 15% of the world's carbon emissions come from the HVAC system of buildings. In the first half of this year, under the demand driven by high temperatures, the global HVAC industry slightly exceeded market expectations. Therefore, low-carbon changes for enterprises or commercial HVAC industries are imperative. Trane Technology is leading a major industry change to reduce atmospheric greenhouse gas emissions from HVAC and transportation refrigeration.

"Compared to the fact that we turn on less air conditioners in daily life, the energy saving in the commercial HVAC field is more meaningful and has a doubling effect. To give a very simple example, a family living area may range from dozens of square meters to about 200 square meters. In order to save electricity, turning on less air conditioners and wearing more clothes can achieve energy saving effect; but in the commercial field, in a space of hundreds of thousands or millions of square meters, energy saving cannot be achieved simply by allowing employees to wear more clothes, which requires a complete system project." Xu Yong introduced.

data shows that 15% of global carbon emissions come from HVAC systems in buildings, and 10% comes from food loss. It is expected that by 2050, the global demand for HVAC will reach three times what it is now. Today, when global climate change is facing challenges, low-carbon changes in the HVAC industry are imperative.

Xu Yong said that Trane Technology boldly proposed the "2030 Sustainable Development Commitment" as early as 2019, including the "billion tons challenge", that is, to help customers reduce 1 billion tons of greenhouse gas emissions, equivalent to 2% of the global annual carbon emissions; to achieve carbon neutrality operations, and reduce the carbon emissions of the company's products and services by nearly 50% by 2030.

Xu Yong said that in order to achieve this commitment, the company has formulated four innovative measures for HVAC solutions. First, we will launch a low-emission solution for Trane commercial air conditioners, and at the same time cooperate with the use of renewable energy. The second is to continue to promote the use of efficient and green refrigerants, that is, the medium that transfers heat in the air-conditioning refrigeration system, that is, refrigerants. Xu Yong introduced that there is a technical reference value in refrigerants called GWP ( global warming potential value), which is an important indicator for measuring the environmental protection performance of refrigerants. "Our company uses a high-efficiency and green refrigerant GWP value is only 1 to 2, which is ahead of many companies in the industry. Our theoretical efficiency COP reaches 8.9, which is at a relatively leading level in the industry." At present, air conditioning solutions using Trane's new generation of refrigerants have been widely used in more than 30 countries and regions around the world. Third, launch more efficient products to comprehensively improve the energy efficiency of air conditioning systems. While providing energy-efficient HVAC products, Tran can also provide a full set of services to comprehensively improve the energy efficiency of HVAC systems and meet customers' needs for temperature control experience and air quality. The fourth is to accelerate the promotion of electrified HVAC solutions. Recently, the expert team of Traling Air Conditioner carried out a full set of electrified low-carbon energy-saving transformation of the Zhanxiang Plaza HVAC system located in the core area of ​​ Shanghai Pudong , and used clean energy to replace the traditional gas boiler heating method to greatly reduce carbon emissions, significantly improve the system operation efficiency, and save operating energy consumption.

"Efficiency and energy conservation are an advantage area that we are very confident in. The overall solution we provide to our customers can achieve the energy conservation goal of more than 30%, which is a great advantage." Xu Yong said.

According to the survey released by CICC recently, the global HVAC market is underestimated. In the first half of this year, the global HVAC industry slightly exceeded market expectations under the demand driven by high temperatures. In China, while the penetration rate of home decoration central air conditioner is rapidly increasing, the application scenarios of central air conditioner market demand are also constantly enriching. Industry online data shows that the domestic sales and shipments of central air conditioners in 2021 are about 112 billion yuan, an increase of 27% year-on-year.

Xu Yong said, "We see the International Energy Agency's forecast for global air conditioning demand is to reach 5.6 billion units by 2050, which is more than three times the scale growth than now.I believe that as a major producer of HVAC equipment, China will have a higher market size than global growth with the accelerated implementation of new infrastructure and low-carbon strategies. "

" China is our strategic market, accounting for more than 60% of the market in the Asia-Pacific region. As early as 2003, we established the Asia-Pacific R&D Center in China and established a world-class laboratory in Taicang, Suzhou. We are one of the first multinational companies to establish a global R&D center in China. "Xu Yong introduced.

. The Jiangmen Neutrino Experimental Station, Institute of Physics, Chinese Academy of Sciences, Jiangmen City, Guangdong Province,

. "We recently completed the Jiangmen Neutrino International Experimental Station project of the Chinese Academy of Sciences. The main body of the project is located 700 meters underground with extremely harsh conditions. In the face of the challenges of high humidity and high temperature, the team delivered with high quality. Finally, it was unanimously recognized and praised by the Institute of High Energy Physics, Chinese Academy of Sciences and related units during acceptance. "Xu Yong said, "In fact, from the highest altitude of 3,500 meters in the country to 700 meters underground, Traling's air conditioning can operate efficiently. "

Xu Yong said that since entering China in the 1980s, Trane has participated in many iconic projects in China, including providing air-conditioning system solutions for the China Pavilion and many national pavilions of the Shanghai World Expo in 2010; assisting the G20 summit and the " coal-to-electricity " project in 2016, as well as the mountain news center and Olympic village temperature control project in the Yanqing competition area of ​​the 2022 Beijing Winter Olympics , etc. "The company looks forward to continuing to participate in more projects in the future, participating in and contributing to China's development. ”
