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.
