Product Description

As a professional manufacturer of purification air conditioners and HVAC equipment, we specialize in high-efficiency heat pump systems. Our CO2 air source heat pump water heater is designed for sustainable and cost-effective heating across industrial, agricultural, and commercial sectors.

✓ High-temperature heating: Water output reaches over 90°C.

✓ Low-temperature resilience: Operates efficiently at -30°C.

✓ Energy Efficiency: Standard COP not less than 4.6.

✓ Eco-Friendly: Uses R744 (Natural CO2) refrigerant.

Operating Principle

The compressor absorbs low-temperature and low-pressure gaseous CO2 refrigerant and compresses it into a supercritical fluid. This fluid enters the gas cooler to release heat into the water. After pressure reduction via the expansion valve, it evaporates by absorbing heat from the ambient air, completing the high-efficiency cycle.
