Abstract: Environmental protection has gradually become a key issue that people pay attention to. As an appliance widely used in People's Daily life, refrigerators must ensure strong environmental protection in the use process. Based on this, this paper will analyze the application performance of the new green environmental refrigerant R290, including the safety performance of the new green environmental refrigerant R290, the refrigeration performance of the new green environmental refrigerant R290 and the physical performance of the new green environmental protection refrigerant R290. And improving the quality of new type of green environmental protection refrigerants R290 in refrigerator application method, which mainly includes the refrigerator refrigerants in the choice of materials, the choice of throttling device in the refrigeration system, reduce the new type of green environmental protection refrigerants R290 leakage probability, avoid new green environmental protection refrigerants R290 gathered around and reduce the new type of green environmental protection refrigerants R290 flammable sources.

Key words: New green environmental refrigerant R290, Fridge, Cooling performance
