Key innovations
The innovation of this product lies in that it adopts a CO2 transcritical compound cycle system and dual working medium technology, combined with CO2 high-temperature thermal energy cascade utilization and vortex tube technology, which significantly improves the low-temperature heat extraction efficiency. The integrated fast defrosting function ensures efficient and stable operation in an extremely cold environment of-35 ° C, which is more energy-saving and environmentally friendly than Freon systems.
Potential economic benefits
This equipment uses CO2 transcritical cycle technology to significantly improve heating efficiency and save a lot of electricity. Its IPLV(H) reaches 2.5, and only consumes about 0.4kWh for every 1kW of heat produced, which saves 0.12kWh electricity compared to traditional Freon heat pumps. It can still operate efficiently and stably at low temperatures of-35℃, reducing operation and maintenance costs in extreme environments.
Potential climate benefits
Efficient and energy-saving, saving 0.12kWh/kW of heat compared to Freon heat pumps, significantly reducing power carbon emissions. CO2 is used as the working medium to avoid leakage of high-GWP refrigerants and achieve double carbon reduction.

Solution details

1. scope of application

 Efficient and energy-saving equipment.

2. Core technologies and processes

 A CO2 transcritical compound cycle system is adopted to absorb heat from the air for heating through a compression refrigeration cycle of two working fluids. Through the cascade utilization of high-temperature heat energy of CO2 and vortex tube technology, the ability of CO2 to extract heat energy from air in the outdoor environment is improved; the integrated design of air heat exchangers achieves rapid defrosting.

3. main technical parameters

 The outdoor ambient temperature is-12℃, the outlet water temperature is 55℃, and the comprehensive heating part-load performance coefficient IPLV(H) is 2.5. The electricity used to produce 1kW of heat is about 0.4kWh.

4. comprehensive benefits

 At the ambient temperature of-35℃, the system can still operate stably with high efficiency; compared with the Freon air source heat pump, 1kW heating capacity saves 0.12kWh of electricity.
