Product Description

Cost Effective CO2 Air Source Heat Pump Water Heater

Specializing in R&D, production, sales, and installation of advanced HVAC equipment. Our heat pump line includes CO2 heat pumps, cascade variable frequency units, air source (chilled water) units, water-cooled chillers, and industrial screw units. These products are widely applied in industry, agriculture, commerce, transportation, and aerospace, including green heating, livestock farming, and biomedicine.

CO2 Heat Pump Mechanism

The Thermodynamic Cycle:

The compressor absorbs low-temperature and low-pressure gaseous carbon dioxide refrigerant from the evaporator, then compresses it into a high-temperature and high-pressure supercritical fluid. This fluid enters the gas cooler to exchange heat with water, releasing a large amount of heat. After being throttled by the expansion valve, it absorbs heat from the surrounding air and repeats the cycle to produce hot water efficiently.

Operating Principle & Advantages

Operating Principle
  • 🚀 High Temperature: Maximum water outlet can reach over 90°C.
  • ❄️ Low Temp Performance: Reliable operation even at ambient temperatures of -30°C.
  • Energy Efficient: Standard COP is not less than 4.6.
  • 🌍 Wide Range: Suitable for domestic or industrial hot water in climates ranging from -30°C to 43°C.
