As a natural working fluid, CO₂ is not flammable or explosive. CO₂ air conditioners do not produce harmful byproducts such as trifluoroacetic acid (TFA), which is truly environmentally friendly and harmless
The energy efficiency ratio (COP value) of CO₂ air conditioners is as high as 1.5-2 times, which reduces energy consumption by more than 30% compared to traditional air conditioners, making green travel more economical
Traditional Freon refrigerants have a GWP value of up to 1000+, while CO₂ refrigerants (R744) have a GWP value of only 1, which truly achieves zero pollution and zero ozone destruction
CO2 refrigerant can still provide stable cooling and heating needs under low temperature conditions, with high efficiency and energy saving
SEC Series product can be integrated defroster system, battery thermal management system, to achieve one panel intelligent control
Application for electric, hydrogen fuel bus, or a hybrid bus, CO₂ air conditioners are perfectly compatible, making new energy transportation more energy-efficient and efficient
