Typical refrigerant gases include fluorocarbons, which are chemical compounds of carbon and fluorine. They were developed mainly as refrigerant gases to be used for refrigerators and air conditioners. There are various types of fluorocarbons such as CFCs, HCFCs, and HFCs with different chemical structures and compositions.
Besides fluorocarbons, other refrigerant gases include ammonia, carbon dioxide, and propane.
Refrigerant Gas Types and Characteristics
【ASHRAE Number】
The ASHRAE number is a number that indicates the type of refrigerant and is defined by ISO817 (International Organization for Standardization) as follows.
【Global Warming Potential】
Global Warming Potential (GWP) is the metric of relative values used to compare the global warming impact of greenhouse gases with the reference gas. Carbon dioxide (CO2) was chosen as this reference gas and its GWP is set equal to one (1.0).
【Toxicity & Flammability Class Table】
Impact of greenhouse gases on the global environment and international regulatory progress
CFCs and HCFCs used in the past had caused ozone depletion problems. CFCs and halon were banned in developed countries in 1996 due to their high impact on the ozone layer. HCFCs, which have a relatively small impact on the ozone layer, were also scheduled to be phased out by 2020, with some exceptions. HFC refrigerant gases that are currently in widespread use as alternatives of CFCs and HCFCs are non-flammable refrigerants (A1). But they have been found to be greenhouse gases that cause global warming. Subsequently, the switch to lower flammable refrigerant gases (A2L) such as HFCs with a lower GWP or HFOs has been promoted. In recent years, the use of HC refrigerants (A3) and natural refrigerants, which have even lower GWP, is being considered.
Xiamen Juda has been focusing on fluorinated chemicals export since year 2004. As one of the earliest exporters of refrigerants in China, we have a complete range of various refrigerants and other fluorinated chemicals.
