1.System compactness:
The refrigeration capacity per unit volume of carbon dioxide is several times that of other refrigerants, and its excellent flow and heat transfer characteristics can significantly reduce the size of compressors and systems, making the entire system more compact.
2.Chemical stability:
Carbon dioxide has good chemical stability, is safe, non-toxic, and non flammable, suitable for various lubricants and commonly used mechanical component materials, and does not decompose to produce harmful gases even at high temperatures.
3.Operating pressure characteristics:
The carbon dioxide heat pump adopts a transcritical cycle, and the operating pressure of the system is relatively high (up to 10MPa), which puts higher requirements on the material strength, sealing, and pipeline connection of the system, but also improves the heating efficiency of the system.
4.Energy efficiency advantage:
When producing high-temperature hot water above 55 ℃, the heating efficiency of carbon dioxide heat pumps is significantly higher than that of ordinary air source heat pumps using traditional fluorine refrigerants, especially in the scenario of high temperature hot water demand from 70 ℃ to 90 ℃.

Q1. How to solve the problem if the unit suddenly stops running?
A: Power on or restart should be delayed for 3 minutes. If there is no response after 3 minutes, check the power on and circuit status of the unit.
Q2.What should be done if the flow alarm of the heat pump unit is triggered?
A: Regularly clean the filter mesh of the filter, check if there are any loose or loose connections in the wiring of the blade water flow switch, and while replenishing water to the dual supply system, remove the air from the water system at the highest point of the system.
Q3.What is the operating principle of carbon dioxide heat pump?
A: The operating principle of a carbon dioxide heat pump is based on the reverse Carnot cycle, which uses carbon dioxide as a refrigerant to absorb heat in low-temperature environments and release heat in high-temperature environments, achieving efficient heating or cooling effects.
