1.Environmental friendliness:
Carbon dioxide, as a natural refrigerant, has an ozone depletion potential (ODP) of 0 and a global warming potential (GWP) of only 1, which is much lower than traditional refrigerants (such as R410A with a GWP of 2080). It is environmentally friendly and meets global carbon neutrality goals.
2.Efficient and energy-saving:
The carbon dioxide heat pump adopts transcritical cycle technology, with high heating efficiency and a COP (energy efficiency ratio) of over 4.0. The heating efficiency attenuation is small in low-temperature environments, and the energy-saving effect is significant. Compared with heating equipment such as oil boilers, gas boilers, and electric boilers, the energy-saving rate is over 50%.
3.High temperature heating:
Carbon dioxide heat pumps can stably supply hot water at temperatures above 90 ℃, meeting the high temperature needs of industries such as food processing and electroplating. Meanwhile, its heating end can adopt various forms such as radiators, floor radiant heating, or fan coil units.
4.Stable low-temperature operation:
The carbon dioxide heat pump can start and operate at a low temperature of -45 ℃, and can still produce high-temperature hot water at an ambient temperature of -35 ℃. It is suitable for heating and domestic hot water supply in cold regions.

Q1.What is the performance coefficient (COP) of a carbon dioxide (CO₂) heat pump?
A: Under standard operating conditions (7 °C ambient temperature and 55 °C outlet water temperature), the COP of a CO₂ heat pump can exceed 4.0. This implies that the system can generate 4 kWh of thermal energy per 1 kWh of electrical energy consumed, demonstrating a substantially higher efficiency compared to electric boilers (COP ≈ 1) and gas boilers (COP ≈ 0.9).
Q2.Does the CO₂ heat pump maintain reliable performance under winter low-temperature conditions?
A: Yes. CO₂ heat pumps are engineered for low-temperature adaptability and can achieve stable operation even at extreme cold temperatures as low as −35 °C. Their heat dissipation is minimized, and the heating efficiency (COP) remains significantly superior to that of conventional heat pumps, rendering them particularly well-suited for regions with harsh winter climates.
