Description
R744 heat pump absorbs heat from the air through natural refrigerant (CO2), providing an important, cost-effective and timely solution for domestic and commercial hot water systems.
The maximum outlet temperature of the CO2 heat pump reaches 95°C-120°C. And it can work normally at -20℃---25℃.
Features:
1. High efficiency and energy saving
Heat pumps work by absorbing and moving heat from the surrounding area,
consuming only a quarter of the cost of traditional electric heaters, saving
users a significant amount of electricity bills.
2. Green and environmental protection
By using a natural refrigerant (CO 2 ), increasingly stringent
decarbonization and environmental protection initiatives across the country can
be easily met.
3. Available 24/7
All-weather operation: stable operation, not affected by any wind, rain
and snow.
4. Durable
Heat pump brand components such as Copeland compressors, Danfoss
electronic expansion valves, Eaton AC contactors and thermal relays guarantee
high quality and long life.
5. Automatic defrost
Provides an advanced defrost cycle with energized coils, eliminating the
need to reverse defrost operation.
6. Intelligent operation
Digital LED display, can connect to Wi-Fi. Remote APP can monitor unit
status in real time, record operating data, check faults, and change set points
and operating modes.
7. Higher capacity
CO2 heat pumps can provide higher capacity and take up less space, easy
to install
8. Widely used
Designed for new and retrofit multifamily and gyms, as well as industrial, hospitality, education, and healthcare applications.
