The characteristics of CO2 heat pump
1. Environmental Sustainability Attributes:
Carbon dioxide (CO₂), serving as a natural refrigerant, exhibits zero ozone depletion potential (ODP) and an ultralow global warming potential (GWP) of 1, a stark contrast to synthetic refrigerants (e.g., R410A with a GWP of 2080). Its ecologically favorable characteristics position it as a climate-conscious alternative for low-carbon refrigeration and heating technologies, aligning with global decarbonization objectives.
2. Efficiency and Energy Conservation Performance:
By leveraging transcritical thermodynamic cycles, CO₂ heat pumps achieve a coefficient of performance (COP) >4.0 under standard conditions, with minimal efficiency losses at low ambient temperatures. Compared to conventional heating systems, they reduce energy consumption by >50%, thereby enhancing the overall energy efficiency of thermal systems.
3.High-Temperature Thermal Output Potential:
CO₂ heat pumps enable stable high-temperature water supply (>90 °C), meeting industrial process demands in sectors such as food processing and electroplating. Their heating systems are compatible with radiators, underfloor heating, and fan coil units, enabling flexible deployment across diverse application scenarios.
4. Low-Temperature Operational Resilience:
Designed for subzero climates, CO₂ heat pumps ensure -45 °C startup reliability and continuous high-temperature water supply at -35 °C ambient conditions. This makes them ideal for cold-region heating and hot water systems, guaranteeing long-term performance under harsh environmental conditions.
