How do CO2 Heat Pumps work?

What is CO2 heat pump?

The CO2 heat pump absorbs heat from the air, enlarged it and passed it to the hot water. Therefore, they are also called "air source heat pumps". The heat pump uses electricity to operate the compressor instead of heating electrical components. Therefore, the efficiency of the CO2 heat pump system is almost five times that of traditional electric water tanks with electric components. They save energy, save funds, and reduce greenhouse gas emissions generated by power generation.


How does the CO2 heat pump work?

1. After the cooling agent CO2 is heated with the external air, leave the evaporator in the form of liquid/steam. Then the steam enters the compressor.

2. The liquid becomes a high -pressure/high -temperature steam and leaves the compressor and enters the gas cooler. The compressor requires electric input to increase the pressure of CO2.

3. Perform heat transfer through the gas cooler. This reduces temperature and pressure. It is still on the critical line.

4. Work fluids reduce the pressure of liquid/steam through the expansion valve. CO2's current temperature is lower than the heat source, and the heat is extracted from the external air through another heat exchanger.


Why is the CO2 heat pump more environmentally friendly?

Because they use the latest development of refrigerant technology, efficient and natural CO2. The best heat pump available has the highest performance coefficient (COP). The CO2 heat pump has a COP of 4.7-7.5. Fewer energy use reduces the impact of power generation on the environment. Because CO2 is a natural gas, it does not need to burn fossil fuel.


Can it be used when the weather becomes cold?

Yes, in fact, recycling CO2 heat pumps can perform excellent performance even in very cold weather. Because natural carbon dioxide (CO2) is used as a unique feature of refrigerant at 1 ° C, CO2 heat pump can still provide four times more energy output than electricity, which can save 75% of the electricity use compared to electric components.

At -5 ° C, the output is almost three times the input. Under the incredible minus 10 ° C, you will get 2.4 times the power output.


Will frost affect the recovery heat pump?

Once the temperature drops below the freezing point, the heat pump will occasionally a defrost cycle to clear the ice on the heat dissipation tablet. The energy required for this is included in the savings calculated above, so it always maintains high performance.


Is CO2 heat pump noise?

CO2 heat pump is the quietest system on the market, with mute function -average noise level: 37 decibels.


Can I replace the existing gas heat water system with CO2 heat pump?

The gas system is easy to replace, because the CO2 heat pump and its cylinder need to be the same service as the gas water heater -cold water in, hot water coming out, and electrical connection.


Can I use it with the photovoltaic solar system?

Combined with your photovoltaic system, recycling CO2 heat pump will optimize your investment, increase your savings in hot water by five times, and avoid exporting to the power grid at a low repurchase price to obtain a small return.
