This study reconstructed the actual fire scene and studied the risk of low-temperature ignition in the insulation material due to the heat generated when compressed refrigerant gas moves from the compressor to the condenser of the refrigerator. In addition, when the refrigerator door is open, the thermal change pattern of each part of the condenser over time was compared and analyzed. As a result of the experiment, considerable heat was generated in the process of moving from the compressor to the condenser, and when the refrigerator door was forcibly opened, the heat continued to accumulate, and it was found that the low-temperature accumulation in the insulation material could cause ignition. Through the results of this study, the ignition mechanism and fire detection options were derived to reconfigure and restore the fire scene in case of a fire due to heat storage while the refrigerator is opened.
