Product Description

Our organization specializes in R&D, production, sales, and installation of advanced HVAC equipment. The product line includes high-efficiency CO2 heat pumps, cascade variable frequency units, air source units, and industrial chillers. These systems are widely applied in green heating, agricultural drying, and biomedicine sectors across over 30 countries.

CO2 Heat Pump Working Process

The compressor absorbs low-temperature and low-pressure gaseous carbon dioxide refrigerant, compressing it into a high-temperature supercritical fluid. This fluid exchanges heat with water in the gas cooler, releasing significant heat to produce hot water efficiently.

Key Performance Features
High-Temperature Output: Reaches water outlet temperatures of more than 90°C.
Extreme Low-Temp Performance: Operates efficiently even at ambient temperatures of -30°C.
Top-Tier Efficiency: Standard COP is not less than 4.6, meeting first-level energy standards.
Wide Application Range: Functional between -30°C and 43°C, suitable for both domestic and industrial use.
