In the context of tackling global climate change and promoting low-carbon development, CO2 air conditioning systems are attracting increasing attention as an emerging technology to save energy and reduce emissions. We have designed, manufactured and measured one such system in an office building in Beijing’s Shunyi district, covering an area of 6,000 m2 and innovatively using CO2 as a refrigerant. Even at an average external temperature of −5 °C, it is able to maintain an indoor temperature of around 25 °C with a heat load of only 58.8 kW. The system has an average COP of around 3 in heating mode and consumes only 0.1 kWh·m−2·d−1 of electricity. This performance demonstrates significant advances in low energy consumption and efficient heating. Such technological advances contribute significantly to the global agenda to reduce greenhouse gas emissions and improve energy efficiency, highlighting the potential and importance of natural refrigerants in creating a more sustainable, low-carbon future.

摘要

In the context of tackling global climate change and promoting low-carbon development, CO2 air conditioning systems are attracting increasing attention as an emerging technology to save energy and reduce emissions. We have designed, manufactured and measured one such system in an office building in Beijing’s Shunyi district, covering an area of 6,000 m2 and innovatively using CO2 as a refrigerant. Even at an average external temperature of −5 °C, it is able to maintain an indoor temperature of around 25 °C with a heat load of only 58.8 kW. The system has an average COP of around 3 in heating mode and consumes only 0.1 kWh·m−2·d−1 of electricity. This performance demonstrates significant advances in low energy consumption and efficient heating. Such technological advances contribute significantly to the global agenda to reduce greenhouse gas emissions and improve energy efficiency, highlighting the potential and importance of natural refrigerants in creating a more sustainable, low-carbon future.
