利用氨水混合物沸点低的特点 ,设计了以氨水混合物为工质的电冷联产循环系统 ,该循环系统可以利用4 0 0～ 4 5 0Ｋ的低温热源 ,实现发电与制冷联合生产 ,整个循环系统的热效率比利用同样温度热源的常规热力发电的热效率高出 7%左右 ,为低温太阳能、地热能、电厂废热的高效利用
Utilizing the characteristic of low boiling point of ammonia mixture, the electric-cold combined cycle system with ammonia-water mixture as working medium is designed. The circulating system can utilize the low-temperature heat source of 400 ~ 4000K to co-produce power generation and refrigeration. The whole circulation system Of the thermal efficiency than the same temperature with conventional thermal power generation thermal efficiency of about 7% higher, for low-temperature solar, geothermal, power plant waste heat efficient use
