| 中文摘要: |
| 氟氯烃及其替代品是近代工业发展起来的制冷工质.该制冷工质气体排放到大气中会吸收地表长波辐射，造成地表温度升高，引起温室效应.研究了12种制冷工质气体的温室效应情况，分别计算了由制冷工质体积分数改变引起的温室效应强度变化，计算并分析了气体温室效应强度对制冷工质体积分数的敏感性系数.结果表明：随着制冷工质体积分数的增加，其引起的温室效应强度均增加，其中CFC-12是氟氯烃及其替代品中对温室效应贡献最大的制冷工质；氟氯烃比其替代品的温室效应强，氟氯烃相对含量的敏感性系数大于其替代品.该结果为寻求有效的减排措施提供了理论指导，以便于优先使用对环境友好的制冷工质，减少甚至停止使用对环境破坏严重的制冷工质，从而在满足经济发展需求基础上达到保护环境的要求. |

| Chlorofluorocarbons (CFCs) and their substitutes are the refrigerants developed by modern industry.They were released into the atmosphere and could absorb the surface long-wave radiation and caused the rising of surface temperature,called greenhouse effect.The greenhouse effect about twelve refrigerant gases was discussed in this paper.The greenhouse effect intensity was calculated as the greenhouse gas concentration increased.The sensitivity coefficient of greenhouse effect based on the refrigerant concentration was calculated and analyzed.The results showed that with the rising of the refrigerant concentration,the greenhouse effect intensity increased.The largest greenhouse effect intensity among CFCs and their substitutes could be achieved by CFC-12.The greenhouse effect intensity caused by CFCs was larger than that caused by their substitutes.So did the sensitivity coefficient of CFCs relative content.These results could provide theoretical guidance for the effective emission reduction measures.It was in the first priority to use the environmentally-friendly refrigerants and reduce or even stop the utilization of the refrigerants seriously damaged to the environment.Therefore,on the basis of economy development,environmental protection could be achieved. |
