Product Description

As a professional manufacturer of purification air conditioners and HVAC equipment, we specialize in R&D, production, sales, and installation. Our product line includes CO2 heat pumps, cascade variable frequency units, air source units, and industrial chillers.

Our solutions are widely applied in industry, agriculture, commerce, and aerospace, serving sectors like green heating, livestock farming, and biomedicine across over 30 countries.

Thermal Efficiency Heat Pump

Working Process: The compressor absorbs low-pressure CO2 refrigerant and compresses it into a high-temperature supercritical fluid. This fluid enters the gas cooler to exchange heat with water, releasing significant heat to produce hot water efficiently.
