Embodiment 1
[0012] (1) The weight percentage of the preparation to be prepared is: 51%: 48.5%: 0.5%, which is used to replace R134a.
[0013] (2) The preparation method is: mixing strictly according to this ratio in the factory, then canning, and then filling.
[0014] (3) Implementation effect: The test results show that after the refrigerant mixed with this formula replaces R134a by perfusion, the cooling capacity is slightly lower than R134a, about 5%, and the COP is slightly higher than R134a, about 2%.
Embodiment 2
[0016] (1) The weight percentage of the preparation to be prepared is: 57%: 42.5%: 0.5%, which is used to replace R134a.
[0017] (2) The preparation method is: mixing strictly according to this ratio in the factory, then canning, and then filling.
[0018] (3) Implementation effect: The test results show that after the refrigerant mixed with this formula replaces R134a by perfusion, the cooling capacity is slightly higher than that of R134a, about 6%, and the COP is equivalent to that of R134a.
Embodiment 3
[0020] (1) The weight percentage of the preparation to be prepared is: 61%: 38.5%: 0.5%, which is used to replace R12.
[0021] (2) The preparation method is: mixing strictly according to this ratio in the factory, then canning, and then filling.
[0022] (3) Implementation effect: The test results show that after the refrigerant mixed with this formula replaces R12 by perfusion, the cooling capacity is slightly higher than that of R12, which is about 2% higher, and the COP is equivalent to that of R12.
