In this research, we reproduced the diesel explosion and examined its characteristics. The mixture of air, refrigerant and oil were sucked into the cylinder, and were compressed by a compressor, which was simulated by a small-scale engine.

Jun 18, 2018 · Experiments were conducted to reproduce the diesel explosion, and its characteristics were examined. A mixture of air, a refrigerant, and lubricating oil was compressed by a compressor and an explosion occurs under certain conditions.

Mar 1, 2017 · Assuming air penetration into refrigerant tubes, the gaseous mixture of the air, refrigerant, and lubricating oil for a compressor was compressed by the compressor with different refrigerant concentrations, and the diesel combustion of the mixture was examined.

Dec 16, 2016 · The two men working on the unit, Barry Purtell, 34, and Dave Lobb, 52, were not trained on how to handle refrigerants or air conditioning units. One of them was a diesel mechanic by trade and they most likely assumed that they knew what they were doing.

Mar 1, 2023 · A mixture of refrigeration oil, refrigerant, and air in the compressor may cause non-ignition combustion (diesel combustion). The risk of such accidents must also be assessed when using weakly or strongly flammable refrigerants in split air conditioners.

To investigate the conditions of self explosion of air, refrigerant and lubricating oil mixture in the compressor of an air conditioner. 2. MATERIALS AND METHODS. 2-1. Experimental Conditions. ・Oil is sprayed into air/refrigerant mixture.・Oil flow ratio was controlled by injection time. 2Adiabatic compression by the engine, self ignition inside.

According to report of Tokyo metropolitan government, the accidents were caused by the air leakage into the refrigerant tube by operation error during pump down. (Diesel explosion) ( エアコン処分。 com) To investigate the conditions of self explosion of air, refrigerant and lubricating oil mixture in the compressor of an air conditioner.

Jan 9, 2017 · The mixture burned via adiabatic compression when the refrigerant concentration was low, which means that accidents during the pump-down were caused by the diesel combustion of the mixture.

Oct 1, 2022 · The refrigerants used were R22, R32, R1234yf, and R290. R22 is old and non-flammable; however, it was selected because it is the refrigerant with the most reports of compressor explosion...

Mar 1, 2017 · The diesel-combustion phenomena that occurred during a pump-down operation were investigated using an experimental apparatus that reproduced the adiabatic compression of the gaseous mixture of the air, refrigerant, and lubricating oil during pump-down.
