냉장고 발화가능성에 대한 연구

다국어 초록 (Multilingual Abstract)

One of the necessary home appliances is a refrigerator. As it is used extensively, the number of refrigerator fire is increasing. This paper has investigated the causes of refrigerator fire and we want this paper is used the references in time of fire investigation. Refrigerator compresses the refrigerant by compressor and transfers liquified refrigerant to the freezer and vaporize it in this place. Refrigerator drops the temperature when the liquified refrigerants are vaporized. There are many kind of refrigerators according to usage, type, capacity. But, the basic structures are two, one is compressor circulating the refrigerant and the other is heating circuit eliminating the frost. There is a motor inside the compressor and the motor generates heat when the refrigerants are compressed. Also heating circuit generates the heat until going up to setting temperature. There are top 4 fire causes in refrigerator. The first is the inside coil short of compressor. The second is the fire of electrical wiring. The third is the insulation deterioration in condenser. The forth is the fire in start relay. Fire investigation should carry out scientifically considering these 4 causes.
