CO2 Heat Pump for HVAC

The CO2 heat pump uses natural carbon dioxide as a refrigerant and achieves a high performance coefficient (COP), which can provide ecological and economic benefits.


Carbon dioxide heat pump is an efficient environmental protection system that can convert one unit of electric energy into four units of heat energy. Compared with alternative heating systems that use electricity or gas, it can significantly save costs.


The unique ability of the R744 heat pump to generate 90°C hot water makes it suitable for a variety of industrial, commercial and residential projects, including food processing plants, dairy products, shopping centers, apartments, hotels, restaurants, hospitals, elderly care, entertainment and education facilities.


CO2 Heat Pump Features:

1. Flexible-the same system can be used for space heating and domestic hot water at the same time

2. Ultra-quiet operation-60dBa

3. No burning-reduce the risk of fire

4. Suitable for ΔT up to 60°C (flow 90°C, return 30°C)

5. Suitable for ambient working temperature of -5°C to 43°C (special device of -15°C or -20°C can be provided)

6. Safety-non-flammable CO₂ refrigerant

7. Programmable-can be set to run during off-peak hours to benefit from low-cost power

8. Multifunctional-suitable for a wide range of uses, from small facilities to large buildings that require hot water or heating

9. Environmental protection-CO2 heat pump uses natural CO₂ refrigerant. The global warming potential (GWP) of this refrigerant is about 1/1700 of R410, and the ozone depletion potential (ODP) is zero

10. Energy saving-Under the best conditions, the CO2 heat pump achieves an excellent coefficient of performance (up to 4.2), which is equivalent to higher energy efficiency. Compared with traditional electric water heaters, CO2 hot water heat pumps can save up to 75% of heat energy. By operating in off-peak hours, energy costs can be further saved, but it is subject to off-peak power supply restrictions.

11. Antifreeze/cold zone device-The heat pump is equipped with a defrost solenoid valve, which opens when the evaporator freezes. The hot gas will then flow through the evaporator and melt the ice. Cannot store water during the defrosting process

Heating to 90°C – Thanks to its innovative design, the CO2 heat pump can produce hot water up to 90°C at low and high ambient temperatures (-20°C to 43°C)

12. One-time heating-suitable for one-time heating of water from low temperature to high temperature (large temperature difference)

13. Reduce storage requirements-because this hot water heat pump can heat water to 90ºC, the size of the water storage tank can be reduced

14. Energy-saving function-this function is an energy-saving function, it can learn the operating mode of the previous four weeks, through natural heat loss to prevent unnecessary heating and the temperature drop of the stored water. Using this feature based on operating data will prevent the device from boiling water unnecessarily.


Warranty:

1). Passed CE and RoHS certification

2). Service life is about 20 years

3). 2 years warranty, buy with confidence
