Product Description
1. This is real CO2 heat pump water heater, with Inverter technology.
2. CO2 is next generantion refrigerant, non-flammable, non-toxic,natural
3. CO2 heat pump can work on -25ºC , and its COP is high , system no need the Aux-heater even in low temp area
4. Our system can make water outcome in 85ºC , suitable for special requirements of hot water ,EVI or any existing heat pump can not do this.
5. Our system is INVETER units, compressor and motors are INVERTER, which can save more energy
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 materials
- higher EER in low ambient ,in -15C even have 1.55EER
