The fourth-generation refrigerant hydrofluoroolefins (HFOs) industry has broad development prospects and China’s production capacity needs to be improved.

Hydrofluoroolefins (HFOs for short) refer to unsaturated organic compounds composed of hydrogen, fluorine and carbon. The ODP (ozone depletion potential) of hydrofluoroolefins is zero and has no destructive effect on the ozone layer. The GWP (global warming potential) is ultra-low and has minimal impact on climate warming. It is a type of environmental protection that…
