Know R290a and HFCs refrigerant

Know R290a and HFCs refrigerant
Apr 28 , 2021

At the climate change summit of the leaders of China, Germany, and France, China announced that it had decided to accept the "Montreal Protocol" Kigali Amendment to strengthen the control of non-carbon dioxide greenhouse gases such as hydrofluorocarbons.

The amendment clearly included 18 hydrofluorocarbons (HFCs) such as HFC134, HFC134a, HFC143, HFC245fa, etc. in the list of controlled substances. According to the reduction schedule set by the "Kigali Amendment", most developed countries will start to reduce HFCs in 2019, and reduce HFCs by 85% from the baseline level by 2036; most developing countries, including China, will reduce HFCs. The production and consumption of HFCs will be frozen in 2024, and the baseline will be reduced by 10% in 2029 and 80% in 2045.

HFCs appear as substitutes for ozone-depleting substances chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), and are widely used as refrigerants in refrigerators, air conditioners and other products. Although HFCs have no destructive effect on the ozone layer, they have a very high greenhouse effect potential, and their power is thousands of times that of carbon dioxide, which is also a greenhouse gas, and is called a "super greenhouse gas."


China is the world's largest producer, consumer and exporter of industrial refrigeration equipment. At present, many institutions in China have recognized that R290 is the only refrigerant that complies with the Kigali Amendment. Some industry companies also stated that R290 refrigerant is the most environmentally friendly and energy-saving product in refrigeration bubbles, with a carbon dioxide equivalent of basically zero.refrigerant R290a, flammable and explosive, is a natural hydrocarbon refrigerant that can be obtained directly from liquefied petroleum gas. Compared with Freon, a synthetic refrigerant, the natural working fluid R290 does not contain chlorine atoms in its molecules, so the ozone depletion potential (ODP value) is 0, which does not have a destructive effect on the ozone layer.

In addition, compared with HFC substances that also have no destructive effect on the ozone layer, the global warming potential (GWP value) of R290 is close to 0, which has no effect on the greenhouse effect.

R290a not only meets the requirements of cooling speed and cooling capacity, but also effectively reduces energy consumption, making it the most ideal refrigerant at present. Xingxing Cold Chain has always adhered to green development, circular development, and low-carbon development. From green design, green manufacturing to green services, it has formed a complete value chain management system. At the same time, it has established green product evaluation standards based on the concept of full life cycle. About the ice making machine also need refrigerant. Such as R404a, R22, R717 so on.
