Description

디플루오로메탄과 1,1,1-트리플루오로에탄과 1,1,1,2-테트라플루오로에탄을 함유하는 냉매 조성물 {Refrigerant composition containing difluoromethane, 1,1,1-trifluoroethane and 1,1,1,2-tetrafluoroethane}Refrigerant composition containing difluoromethane, 1,1,1-trifluoroethane and 1,1 (1,1,1-trifluoroethane and 1,1,1-trifluoroethane) , 1,2-tetrafluoroethane}

본 발명은 지구의 오존층을 파괴하는 것으로 알려진 클로로디플루오로메탄 (CHClF2, 이하 HCFC-22)을 대체하기 위한 냉매 조성물에 관한 것이다.The present invention relates to a refrigerant composition for replacing chlorodifluoromethane (CHClF 2 , hereafter HCFC-22) known to destroy the earth's ozone layer.

CFC 화합물은 이미 잘 알려진 바와 같이 지구의 오존층을 파괴하는 물질로 밝혀짐에 따라 몬트리올 의정서에 의해 그 생산과 사용이 규제를 받고 있으며 미국 등에서는 1996년부터 이미 사용이 금지된 상태이다. 그리고, CFC 화합물의 대체물질로 개발된 HCFC-22를 비롯한 HCFC계열의 화합물도 CFC 화합물만큼 심하지는 않으나 오존층을 파괴하는 것으로 알려져 점차 그 사용량을 규제하여 2030년경부터는 사용이 전면적으로 금지될 예정이다.As CFC compounds are already known to destroy the earth's ozone layer, their production and use have been regulated by the Montreal Protocol and have been banned since 1996 in the United States. In addition, HCFC-based compounds, including HCFC-22, developed as substitutes for CFC compounds, are not as severe as CFC compounds, but are known to destroy the ozone layer, and their usage is gradually regulated.

따라서, HCFC-22의 대체물질 개발에 대하여 많은 연구가 이루어지고 있으며 대표적으로는 미국냉동공조학회(ASHRAE)의 HFC-407C와 HFC-410A를 들 수가 있다. 여기에서, HFC-407C는 HFC-32/125/134a가 23/25/52의 중량%로 혼합된 냉매 조성물이고, HFC-410A는 HFC-32/125가 50/50의 중량%로 혼합된 냉매 조성물이다.Therefore, a lot of research is being conducted on the development of alternatives to HCFC-22, and representative examples are HFC-407C and HFC-410A of the American Society of Refrigeration and Air Conditioning (ASHRAE). Here, HFC-407C is a refrigerant composition in which HFC-32 / 125 / 134a is mixed at 23/25/52 wt%, and HFC-410A is refrigerant in which HFC-32 / 125 is mixed at 50/50 wt% Composition.

상기 조건에서 HCFC-22와 HFC-407C와 HFC-410A에 대하여 성능을 평가하였으며 결과는 다음의 [표 1]에 기재하였다.Performance was evaluated for HCFC-22, HFC-407C and HFC-410A under the above conditions, and the results are shown in the following [Table 1].

[표 1]로부터 HFC-407C는 HCFC-22와 비교하여 COP는 약간 떨어지나 VC 및 압력은 거의 비슷함을 알 수 있고, HFC-410A의 경우는 COP는 비슷하고 VC는 우수하나 압력이 HCFC-22에 비해 다소 높음을 알 수 있다.From Table 1, HFC-407C shows a little drop in COP compared to HCFC-22, but VC and pressure are almost similar.For HFC-410A, COP is similar and VC is excellent, but pressure is HCFC-22. It is somewhat higher than.

그런데, 냉매의 성능이 이러한 범위 내에 있을 경우 HCFC-22의 대체냉매로서 사용이 가능한 것으로 평가되고 있으므로 후술하는 실시예에서는 이들 결과와 비교하였다.However, when the performance of the refrigerant falls within this range, it is evaluated that it can be used as an alternative refrigerant of HCFC-22. Thus, the examples described later were compared with these results.
