Can r134a be mixed with r410a?

Can r134a be mixed with r410a?

If R134a refrigerant be mixed with R410a, there will be many adverse consequences. Performance in the following aspects:

1. In terms of physical and chemical properties, R134a is a single refrigerant, chemically named 1,1, 2-tetrafluoroethane, with a standard boiling point of -26.1 ℃; R410a is a mixture of difluoromethane (R32) and pentafluoroethane (R125) at a mass ratio of about 1:1, with a standard boiling point of about -51.6 ° C.If r134a be mixed with r410a After mixing, the boiling point, condensing pressure, evaporation pressure and other thermodynamic properties of the refrigerant deviate from the design parameters, causing the refrigeration system to fail to operate normally. In addition, in the complex environment of high temperature, high pressure and compressor operation, chemical reactions may occur, generate corrosive new compounds, corrode the metal pipes and compressor components of the refrigeration system, and shorten the life of the equipment.

2. In terms of system performance, the refrigeration system is designed based on specific refrigerant characteristics.If r134a be mixed with r410a? After mixing, the thermal properties of the refrigerant change, evaporator evaporation and condenser condensation can not r134a be reach the best state, cooling capacity decreases, efficiency decreases, and operating costs increase. At the same time, the compressor work load changes, there may be high exhaust temperature, abnormal pressure and other problems, long-term abnormal operation will accelerate wear, and even lead to serious failures such as cylinder, motor burn, so that the system can not work.

3. In terms of safety, R32 in R410a has certain flammability. If R134a refrigerant be mixed with R410a .After mixing ,flammability and explosion characteristics may change. The leakage of the refrigeration system may cause an explosion or fire if it encounters an ignition source or high temperature.

4,If R134a refrigerant be mixed with R410a, mixed refrigerant pressure characteristics are different, so that the system pressure control is difficult, too high pressure will lead to pipeline rupture, valve damage, increase the risk of leakage; Too low pressure will affect the normal operation and reduce the cooling effect.
