There are few R1234ze refrigerant manufacturers in the world and the market size is small.

The representative products of the fourth generation hydrofluoroolefins (HFOs) refrigerants are mainly R1234ze and R1234yf. R1234ze, also known as HFO-1234ze, whose chemical name is 1,3,3,3-tetrafluoropropene, has the advantages of non-toxic, non-flammable, no flash point, stable chemical properties, etc., and is mainly used as a refrigerant. Compared with the previous three generations of refrigerants, R1234ze has zero ODP (ozone depletion potential), low GWP (global warming potential), does not destroy the ozone layer and has a low greenhouse effect. It has obvious environmental protection advantages, so it has attracted attention.

As a new environmentally friendly refrigerant, R1234ze can be used in the field of air conditioning. For example, it can replace the third-generation hydrofluorocarbons (HFCs) refrigerant R134a in automobile air conditioning systems. The ODP of R134a is zero, but the GWP is high and the greenhouse effect is obvious. In the context of increasing environmental protection requirements, it will be replaced by fourth-generation refrigerants such as R1234ze, which are more environmentally friendly. In addition to refrigerant, R1234ze can also be used as a foaming agent, aerosol propellant, cleaning agent, organic synthesis intermediate, etc.

R1234ze can also be used as a refrigerant in high-temperature heat pumps. High-temperature heat pumps use industrial wastewater as a heat source to provide hot water, which is one of the important ways to recover industrial waste heat. The hot water generated can be used for heating. There are many types of refrigerants that can be used in high-temperature heat pumps. Compared with other refrigerants, R1234ze has the characteristics of larger heating capacity per unit volume, high COP value under high-temperature conditions, moderate pressure ratio, low compressor exhaust temperature, stable chemical properties, Environmentally friendly and other advantages. From this point of view, R1234ze also has a large market space in high-temperature heat pumps.

According to the “2021-2025 R1234ze Refrigerant Industry In-depth Market Research and Investment Strategy Suggestions Report” released by the Industrial Research Center, R1234ze It is a new refrigerant jointly developed by Honeywell and DuPont of the United States. It has a production patent. If other companies want to produce R1234ze, they need to cooperate with Honeywell and DuPont to OEM for them, or independently develop new production processes. . Compared with R1234yf, the number of R1234ze manufacturers in the world is small, and R1234yf has been widely used in automobile air conditioners. Europe has designated R1234yf as a substitute for R134a, while the application scale of R1234ze is small.

Globally, the first-generation refrigerants have been eliminated, the second-generation refrigerants are in the final stages of elimination, and the third-generation refrigerants are in the process of being eliminated. The market space for fourth-generation refrigerants will be larger in the future, so R1234ze has broad development prospects. . In my country, refrigerant manufacturers are accelerating the development of fourth-generation refrigerants. Juhua New Materials has developed a new R1234ze preparation method and has an invention patent. But at present, our country does not yet have the large-scale mass production capacity of R1234ze.

Industry analysts said that R1234ze and R1234yf both belong to the fourth generation HFOs refrigerants and have the advantages of not damaging the ozone layer and having a low greenhouse effect. , as the third generation refrigerants are gradually phased out, there will be huge market space in the future. However, at this stage, there are few R1234ze manufacturers worldwide and the market size is small. R1234yf has been promoted and applied in automotive air conditioners, while most applications of R1234ze are still in the testing stage. In the short term, the market space for R1234ze is small, but in the long term, its market prospects are broad.
