Description
실시예는 혼합 냉매에 관한 것이다.The embodiment relates to a mixed refrigerant.
종래에는 냉동기, 에어컨, 열펌프 등의 냉매로서 메탄 또는 에탄에서 유도되는 염화불화탄소(Chlorofluorocarbon, 이하 CFC라 한다)와 수소화염화불화탄소(Hydrochlorofluorocarbon, 이하 HCFC라 한다)가 주로 사용되었다.Conventionally, as refrigerants for refrigerators, air conditioners, and heat pumps, chlorofluorocarbons (Chlorofluorocarbons, hereinafter referred to as CFCs) and hydrochlorofluorocarbons (hereinafter referred to as HCFCs) derived from methane or ethane have been mainly used.
그러나, 최근에는 CFC와 HCFC에 의한 성층권 내 오존층 붕괴가 중요한 지구환경문제로 대두되었고, 이로 인해 성층권 오존을 붕괴하는 CFC와 HCFC의 생산과 소비는 1987년에 만들어진 몬트리올 의정서에 의해 규제를 받고 있다. However, recently, the collapse of the ozone layer in the stratosphere by CFCs and HCFCs has emerged as an important global environmental problem, and the production and consumption of CFCs and HCFCs that decay stratospheric ozone are regulated by the Montreal Protocol established in 1987.
또한 최근에는 오존층 붕괴 문제뿐만 아니라 지구 온난화 문제도 급속도로 부상하기 시작했고 1997년의 교토 의정서는 지구온난화지수(Global warming potential, 이하 GWP라 한다)가 높은 냉매의 사용을 자제할 것을 강력히 권고하고 있다. 이런 추세를 반영하여 유럽과 일본의 가정용 에어컨, 히트 펌프 등을 생산하는 업체들은 지구온난화지수(GWP)가 낮은 냉매를 개발하여 사용하려 하고 있다.In addition, in recent years, not only the ozone layer collapse problem, but also the global warming problem has begun to emerge rapidly, and the Kyoto Protocol in 1997 strongly recommends refraining from the use of refrigerants with high global warming potential (GWP). . Reflecting this trend, companies that produce household air conditioners and heat pumps in Europe and Japan are trying to develop and use refrigerants with low global warming potential (GWP).
어떤 물질이 기존 냉매의 대체냉매로 유용하려면 우선 기존 냉매와 유사한 성능계수(Coefficient of performance, 이하 COP라 한다)를 가져야 한다. 여기서 성능계수(COP)란 압축기에 가해진 일과 대비한 총 냉동효과를 의미하는 것으로서 COP가 클수록 냉동/공조기의 에너지 효율이 좋다.In order for a substance to be useful as an alternative refrigerant for an existing refrigerant, it must first have a coefficient of performance similar to that of the existing refrigerant (hereinafter referred to as COP). Here, the coefficient of performance (COP) refers to the total refrigeration effect compared to the work applied to the compressor. The larger the COP, the better the energy efficiency of the refrigeration/air conditioner.
또한, 압축기를 크게 개조하지 않고 사용하려면 대체냉매가 기존 냉매와 비슷한 증기압을 가져서 궁극적으로 비슷한 체적용량(Volumetric capacity, 이하 VC라 한다)을 제공해야 한다. 여기서 체적용량(VC)이란 단위 체적 당 냉동 효과를 뜻하는데 이것은 압축기의 크기를 나타내는 인자로서 대개 증기압에 비례하고 단위는 kJ/m3이다. 대체냉매가 기존 냉매와 비슷한 체적용량을 낸다면 제조업체는 압축기를 바꾸거나 크게 개조하지 않고도 냉동/공조기를 제작할 수 있어 매우 유리하며 이것은 보통 Drop-in 대체라고 불린다. In addition, in order to use the compressor without major modification, the alternative refrigerant must have a vapor pressure similar to that of the existing refrigerant and ultimately provide a similar volumetric capacity (hereinafter referred to as VC). Here, the volumetric capacity (VC) means the refrigeration effect per unit volume, which is a factor representing the size of the compressor, which is usually proportional to the vapor pressure and the unit is kJ/m 3 . If the replacement refrigerant has a volume capacity similar to that of the existing refrigerant, the manufacturer can make a refrigeration/air conditioner without changing or major modifications of the compressor, which is very advantageous, which is commonly referred to as a drop-in replacement.
그러나 지금까지의 연구 결과 순수 물질로 기존 냉매를 대체하는 경우 대체냉매의 체적용량이 달라서 필연적으로 압축기를 바꾸거나 크게 개조해야 하며 또 기존 냉매와 비슷한 성능계수를 내기가 어렵다는 것이 밝혀졌다.However, as a result of the research so far, it has been found that when replacing the existing refrigerant with a pure substance, the volume capacity of the alternative refrigerant is different, so the compressor must be changed or remodeled significantly, and it is difficult to produce a performance coefficient similar to that of the existing refrigerant.
이런 문제를 해결할 수 있는 방법 중 하나는 혼합냉매를 이용하는 것이다. One of the ways to solve this problem is to use a mixed refrigerant.
즉, 혼합냉매의 특성은 조성을 잘 배합해서 성능계수를 기존 냉매와 비슷하게 하고 동시에 기존 냉매와 비슷한 체적용량(VC)을 내게 하며 이로써 압축기를 크게 개조할 필요가 없게 만들 수 있는 것이다.In other words, the characteristics of the mixed refrigerant are that the composition is well-mixed to make the coefficient of performance similar to that of the existing refrigerant, and at the same time give a similar volumetric capacity (VC) to that of the existing refrigerant, thereby making it possible to make it unnecessary to remodel the compressor.
따라서, 상기와 같은 문제점을 해결할 수 있는 혼한 냉매의 필요성이 요구된다.Therefore, there is a need for a mixed refrigerant capable of solving the above problems.
실시예는 낮은 지구온난화지수, 기존 냉매와 유사한 체적 용량을 가지는 혼합 냉매를 제공하고자 한다.The embodiment is to provide a mixed refrigerant having a low global warming index and a volume capacity similar to that of an existing refrigerant.
