Features of CO2(R744) Heat Pump:
- The water can be heat up to 90C, high temperature output can reduce the volume of the storage tank and suitable for some specific usage (disinfection, cleaning)
- Suitable for low ambient. Even in -43ºC, it can efficiently offer heat
- Max COP is 5.5, our multi function model can reach max COP 7 (provide free cooling when producing heat)
- Inverter control to offer various power accordingly to real requirement, save energy
- Modules design, can reach higher Power by combined installation
- 6 layers of pressure protection
- Intelligent inverter control , can save 50% energy during defrosting
- Smart wireless control, also RS485/Modbus central control
- Programmable digital interface with touch keys
- Monobloc design, no need extra work for high pressure refrigerant connection
The advantages of CO2 as a refrigerant
- Climate-neutral environmentally friendly refrigerant R744 (CO2)
- Without environmentally hazardous decomposition products
- No additional contribution to the greenhouse effect (GWP = 1)
- Does not contribute to the ozone depletion (ODP = 0)
- No disposal and recycling requirements
- No availability constraints
- Low security requirements - Safety Group A1
- Non-toxic, non-flammable, thermally stable, compatible with other material
