1. Environmentally friendly features
Carbon dioxide (CO ₂), as a natural refrigerant, has zero ozone depletion potential (ODP) and a global warming potential (GWP) as low as 1, far lower than traditional refrigerants (such as R410A with a GWP of up to 2080). Its environmental load is extremely low, making it the preferred alternative technology for green environmental protection in the fields of refrigeration and heating.
2. Advantages of high efficiency and energy conservation
The carbon dioxide heat pump relies on transcritical cycle technology, with an energy efficiency ratio (COP) exceeding 4.0 under standard operating conditions, and a low heating efficiency decay rate under low-temperature conditions, demonstrating outstanding energy-saving performance. Compared to traditional heating equipment, the energy-saving efficiency of carbon dioxide heat pumps has increased by over 50%, significantly optimizing the overall energy efficiency level of the system.
3. High temperature heating performance
The carbon dioxide heat pump can stably output high-temperature hot water above 90 ℃, fully meeting the high-temperature process requirements of industrial fields such as food processing and electroplating. Its heating terminal supports various forms such as radiators, floor radiant heating, and fan coil units, with high adaptability and flexible coverage of diverse application scenarios.
4. Adaptability to low temperature conditions
The carbon dioxide heat pump is designed specifically for extremely cold climates, capable of starting and operating at extreme low temperatures of -45 ℃, and providing continuous and stable supply of high-temperature hot water at ambient temperatures of -35 ℃. It is an ideal choice for heating and hot water supply in cold regions, ensuring long-term and reliable operation under harsh weather conditions.

Q1.Do you want to add refrigerant frequently?
A: Basically no need! CO ₂ is a closed cycle, similar to a refrigerator, and can be used for more than 10 years without any need for maintenance.
Q2.Will it not work when it is particularly cold in winter?
A: A regular heat pump may strike at -10 ℃, while a CO ₂ heat pump can still function normally at -25 ℃ (as used in Nordic countries and Canada), but its efficiency may slightly decrease in extreme weather conditions.
Q3.Do Heat Pumps Match Air Conditioners in Cooling Efficiency?
A: When comparing models with identical SEER ratings, the cooling performance of heat pumps and air conditioners exhibits minimal variance. However, factors such as home size, window/door quality, insulation effectiveness, and solar exposure (building orientation) significantly influence overall cooling outcomes.
