In the global pursuit of carbon neutrality and sustainable development, the demand for clean, efficient heating and hot water systems has never been higher. CO₂ heat pumps stand out as a revolutionary choice, leveraging natural refrigerant CO₂ (R744) to deliver high-performance hot water and heating while minimizing environmental impact. From frigid winters to industrial settings, these systems redefine energy efficiency and reliability.
The compressor draws in low-temperature, low-pressure gaseous CO₂ from the evaporator and compresses it into a high-temperature, high-pressure supercritical fluid.
This supercritical fluid flows into the gas cooler, where it transfers heat to water—raising the water temperature to up to 90°C for hot water or 75°C for heating.
After throttling and depressurization via the expansion valve, the CO₂ absorbs heat from ambient air (even at -35°C) in the evaporator, evaporates back into a gas, and re-enters the compressor to repeat the cycle.
This design ensures efficient heat transfer even in extreme temperatures, making CO₂ heat pumps versatile across climates.
Leomon’s CO₂ heat pumps offer a range of advantages that set them apart from traditional systems:
Environmental Friendliness: CO₂ (R744) has an ODP (Ozone Depletion Potential) of 0 and GWP (Global Warming Potential) of 1, making it non-toxic, non-flammable, and zero-pollution—fully aligned with global environmental standards.
Exceptional High-Temperature Performance: Capable of producing hot water up to 90°C and heating water at 65°C/45°C (supply/return), suitable for radiators and industrial processes.
Superior Low-Temperature Reliability: Operates stably at ambient temperatures as low as -35°C, with a COP (Coefficient of Performance) of 1.8 even at -30°C—ideal for cold regions like northern China.
High Energy Efficiency: Under standard conditions, COP reaches 4.5, significantly reducing energy consumption compared to electric boilers or gas heaters.
Intelligent Control: Equipped with a smart system featuring real-time monitoring, remote operation via APP, and automatic defrosting, ensuring hassle-free management.
Domestic & Commercial Hot Water: Ideal for hotels, schools, and dormitories. For example, a university dormitory project uses a 20HP CO₂ heat pump to supply 20 tons of 60°C hot water daily, meeting student needs efficiently.
Industrial Processes: Used in food processing, parts cleaning, and drying. A Singapore factory project utilizes 10HP units to produce 75°C high-purity water while providing cooling, achieving combined heating and cooling efficiency of 8.
Heating in Extreme Cold: Deployed in railway bureaus and coal mine areas. A railway bureau project in a -40°C region uses CO₂ heat pumps to maintain 20°C indoor temperatures with 70°C supply water, ensuring comfort in frigid conditions.
