Example Embodiment
[0053] Example 1:
[0054] A mixed refrigerant that replaces HCFC-22 under high temperature conditions, and is composed of the following three components according to mass percentage: fluoroethane, 85%; propylene, 5%; propane, 10%.
[0055] When replacing HCFC-22 under high temperature conditions, HFC-161, HC-1270, and HC-290 are physically mixed in the liquid phase at a mass percentage of 85:5:10 to obtain the above-mentioned mixed refrigerant.
