It is about.

일반적으로 냉장고라 함은 압축기, 콘덴서, 팽창밸브및 증발기등으로 구성되는 한편 냉매인 프레온가스가 순환함에 따라 열을 주고 받음으로써 냉장시스템을 구현하고 있다. 여기서 냉매로 사용되는 프레온가스는 환경오염 문제가 야기되고 있는 실정이다. 또한, 압축기 구동시 발생되는 진동이나 소음등도 문제점으로 지적되고 있다.In general, a refrigerator is composed of a compressor, a condenser, an expansion valve, and an evaporator, and implements a refrigeration system by exchanging heat as the refrigerant gas circulates. Freon gas used as the refrigerant is a situation that causes environmental pollution. In addition, vibration or noise generated when driving the compressor is also pointed out as a problem.

한편, 아름다움을 가꾸는 여성들의 필수품으로 사용되고 있는 화장품들은 그 종류가 많아지고 사용용도도 다양해짐에 따라 여러 종류의 화장품등이 개발되는 한편, 이것들을 사용하기 위해 지정 장소나 이동 장소에 구애받지 않게 다양한 형태의 용기에 넣어서 편리하게 사용하도록 되어 있다. 그러나, 화장품은 저온에서 보관하여 장기간 신선도를 유지되는 액체 또는 여러 상태의 겔로써 고가임으로 항상 양질의 상태로 사용하기를 모든 여성들이 원하게 된다.On the other hand, cosmetics that are used as necessities of women who care for beauty are developed with various kinds of cosmetics and various types of use, while various kinds of cosmetics are developed to use them. It is put in a container of the form for convenient use. However, all women want cosmetics to be stored at low temperature and kept in a fresh state for a long time and are used in high quality at all times as expensive as a gel or liquid in various states.

이와 같은 상황때문에 일반적인 냉장고대신에 열전소자를 이용한 특수목적의 냉장고가 여러가지로 개발되고 있는 바, 그 중 대한민국 특허공개 1998-27319 ( 발명의 명칭 : 열전소자를 이용한 냉장고)는 일반 냉장고에서 사용되는 냉매에 의한 환경오염을 방지하고 구성및 장치가 복잡한 시스템을 개선하여 압축기의 구동에 따른 진동및 소음문제를 해결한 냉장고인 것이다.Due to such a situation, various special purpose refrigerators using thermoelectric elements have been developed instead of general refrigerators.
