Research of refrigerant substitution, new refrigerant development and application of natural refrigerants.

With the formulation of a series of international conventions, such as the Montreal protocol and the Kyoto Protocol,the HCFCs refrigerant elimination process had been accelerated,because the problem of global warming and ozone destruction has become increasingly serious.As a big country for refrigerant use, our country has encountered tremendous pressure at this time,but at the same time, when we use excessive refrigerants such as R32, and we also should search for new types of sustainable refrigerants, or the development of more refrigeration technology to save the use of refrigerant ,this is what we should actively do.In addition, the formulation of relevant standards related to HCFCs alternative technology is the foundation of the development of the industry and should be paid special attention.
