R32 Vs R410A: Refrigerant Comparison In All Aspects

As the global concerns about climate change and environmental preservation are rising nowadays, the air conditioning industry is actively searching for more environmentally friendly and more effective cooling solutions. In which the option of refrigerant becomes the key factor to measure the air conditioning ability in environmental friendliness. Currently, R32 and R410A are two widely used refrigerants in the market. So what are the differences between them? Which one is better? Here we will have a comprehensive introduction.

I. What is R410A and R32

II. Comparison of environmental performance

1. GWP: R32 is more environmentally friendly.

GWP (Global Warming Potential) is a key data point to measure the impact of greenhouse gas on the global climate change. R410A has a GWP of 2088, while R32 has only 675, roughly 1/3 of R410A. It means when the gas leakage is the same weight, R32 impacts less than R410A on climate change.

2. Ozone damage potential (ODP)

Both two types of gas are in the same 0 ODP, which will not harm the ozone layer. But due to the high GWP of R410, it is less competitive than R32 in overall environmental friendliness.

III. Energy-efficiency comparison

R32 has better thermodynamic performance with less mass required in each unit of cooling capacity. So it will provide a higher efficiency in air compressing and energy utilization. The data shows, under the same conditions, the EER of R32 air conditioners is 10% higher than those with R410A.

IV. Operation safety comparison.

R410A is a non-flammable gas, which can be much safer when using; R32 belongs to the A2L class, which is slightly flammable. Well, it does not mean R32 is not safe. It is absolutely reliable with reasonable designs and regulated operations. It is the fact that many countries and regions include R32 in the standard of air conditioning refrigerants.

Notice: Proper installations, ventilation designs, and refrigerant management are key points of ensuring the safety of R32.

V. Market trend and policy orientation

A number of international organizations and countries are now pushing the elimination of high GWP refrigerants. For example:

• UN F-Gas Law: It steadily limits the use of high-GWP refrigerants.
• Japan and Australia: They are widely pursuing R32 as an alternative to R410A;
• China: Some mainstream AC manufacturers had already chosen R32 as the main gas equipped in the exporting models.

Under such a trend, picking R32 air conditioning products is not only suitable for the environmental protection trend but also more capable of market competition.

VI. Why is R32 the mainstream in the future?

It needs more security management during the transportation and use of R32 refrigerant, but the comprehensive advantages in environmental protection, energy efficiency, and market trends make it the future direction of air conditioning refrigerant.

As a manufacturer, dealer, or consumer, acknowledging the performance and trend of refrigerants is of vital importance to making wise decisions. R32 is not only a refrigerant innovation but also a vital step towards a green future.
