由七○四研究所机械和工业部通用机械研究所联合设计,开封通用机械厂试制的150万千卡/时蒸汽两效溴化锂吸收式制冷机,1981年12月在上海国棉廿一厂进行调试,于1982年3月26日～29日在上海鉴定。这是国内首次鉴定的两效机组。参加这次鉴定的有来自全国十二个省市的有关上级领导、科研设计单位、高等院校、工厂等91个单位,170多名代表。与会代表通过对机组性能的复测和审查,认为:该机在设计工况下,实测制泠量174万千卡/时,热力系数1.402,达到并超过了原设计指标;机组的设计和试制是成功的,其中,主要性能指标接
Jointly designed by the General Machinery Research Institute of the Ministry of Machinery and Industry of the Ministry of Machinery and Industry of the 704 Research Institute, a 1.5 million kcal / hour two-effect lithium bromide absorption chiller for trial trial opened at General Machinery Plant was carried out in December 1981 at the Cotton Giant 21 plant in Shanghai Commissioning, in March 26, 1982 to 29 in Shanghai appraisal. This is the first identification of two-effect unit. Attending this appraisal came from 91 units and 170 delegates from higher authorities, research and design institutes, institutions of higher learning and factories from 12 provinces and cities nationwide. Through the retest and review of the performance of the unit, the delegates said: Under the condition of design, the measured coefficient of heat output is 1.74 million kcal / h and the thermal coefficient is 1.402, which meets and surpasses the original design index; the design and trial of the unit Is successful, among them, the main performance index is connected
