What Is The Best Refrigerant for Air Conditioning in 2024?

R32 refrigerant

R32 is short for difluoromethane, which is a coolant with zero ozone loss potential. It is a gas at room temperature and a colorless transparent liquid under its own pressure. It is easily soluble in oil and difficult to dissolve in water. Boiling point -52 degrees, freezing point -78.4 degrees, critical temperature 59.5 degrees.https://heartfev.com

Refrigerant R410A

R410A is a new type of environmentally friendly refrigerant that does not deplete the ozone layer. It has a working pressure approximately 1.6 times that of ordinary R22 air conditioners, resulting in higher cooling and heating efficiency. It enhances air conditioning performance without causing harm to the ozone layer. R410A is a new refrigerant composed of two quasi-azeotropic mixtures, primarily consisting of hydrogen, fluorine, and carbon (referred to as HFC). It possesses stable, non-toxic, and superior performance characteristics.

At the same time, because it does not contain chlorine, it will not react with ozone, that is, it will not destroy the ozone layer. In addition, the use of new refrigerant air conditioning in terms of performance will also be improved. R410A is so far the most suitable refrigerant internationally recognized to replace R22, and has been popularized in Europe, the United States, Japan and other countries.https://heartfev.com

Performance comparison between R32 and R410A: 1. Global Warming Potential (GWP): - R32: GWP of 675 - R410A: GWP of 2,088 2. Energy Efficiency: - R32: Higher energy efficiency compared to R410A - R410A: Lower energy efficiency compared to R32 3. Refrigeration Capacity: - R32: Higher refrigeration capacity compared to R410A - R410A: Lower refrigeration capacity compared to R32 4. System Pressure: - R32: Lower system pressure compared to R410A - R410A: Higher system pressure compared to R32 5. Flammability: - R32: Mildly flammable - R410A: Non-flammable 6. Ozone Depletion Potential (ODP): - R32: ODP of 0 - R410A: ODP of 0 Please note that the above information is a general comparison and may vary depending on specific applications and system configurations.

1, thermal physical properties: R32 charge amount can be reduced, only 0.71 times of R410A, R32 system working pressure is higher than R410A, but the maximum increase is not more than 2.6%, which is equivalent to the pressure requirements of R410A system, while R32 system exhaust temperature is higher than R410A maximum increase of 35.3℃, the existing compressor needs to be redesigned.

2 environmental characteristics: ODP value (ozone-depleting potential value) is 0, but R32 GWP value (global warming potential value) is moderate. Compared with R22, the CO2 emission reduction ratio of R32 is 77.6%, and the CO2 emission reduction of R410A is only 2.5%, which is significantly better than R410A.

3, safety: R32 and R410A are non-toxic, while R32 is flammable, but among several alternatives to R22, R32, R290, R161, R1234YF, R32 has the highest lower flammability limit (LFL), making it the most difficult to ignite and relatively safe.

4, cycle performance: in terms of theoretical cycle performance, the cooling capacity of the R32 system is 12.6% higher than that of R410A, the power consumption is increased by 8.1%, and the comprehensive energy saving is 4.3%. The experimental results also show that the energy efficiency ratio of the refrigeration system using R32 is slightly higher than that of R410A.
