Diesel combustion of oil and refrigerant mixture during pump-down of air conditioners.
Number: pap. n. 453
Author(s) : HIGASHI T., SAITOH S., DANG C. B., et al.
Summary
In this study, we aimed to reproduce the diesel combustion that may occur during the pump-down of air conditioners and measured the pressure inside the compressor when this combustion occurred. As refrigerants, we examined R1234yf, R32, R410A, R134a, R22, and R125, and investigated different combinations of refrigerants and lubricating oil by changing the refrigerant concentration. We determined that the combustion accidents that may occur during pump-down are caused by the diesel combustion of the air, refrigerant, and oil mixture even though the refrigerant is categorized as being non-flammable.
