🚀 Product Description

Cost Effective CO2 Air Source Heat Pump Water Heater

As one of the earliest professional manufacturers of purification air conditioners and HVAC equipment, we specialize in R&D, production, sales, and installation. Our core segments include air conditioning systems and heat pump systems. The heat pump line includes CO2 heat pumps, cascade variable frequency units, air source units, water-cooled chillers, and industrial screw units.

The compressor absorbs low-temperature and low-pressure gaseous carbon dioxide refrigerant from the evaporator, and 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 throttling by the expansion valve, it absorbs heat from the surrounding air and evaporates, completing the cycle to produce hot water.
