一、概述自1966年我国试制成功100万千卡/时蒸汽单效溴化锂吸收式制冷机以来,溴化锂吸收式制冷机在我国得到了较快的发展。然而,随着制冷技术的发展,尤其是“节能”呼声日益高涨,普通(单效)溴化锂吸收式制冷机已不能满足我国国民经济发展的需要,特别是轻纺工业发展的需要。因为这种机型所需加热蒸汽的压力不宜过高(一般为1公斤/厘米~2表压),不少用户往往需要先把蒸汽减压,再供机器使用。这不仅增加了节流设备,而且造成节流过程中的能量损失,使热能的利用效率大为降低。为了提高热能的利用效率,1980年,由六机部七○四研究所、一机部通用机械研究所联合设计、开封通用机械厂承制,为上海国棉廿
I. Overview Since 1966 China’s successful trial of 100 million kcal / hour steam absorption lithium bromide absorption chiller since, lithium bromide absorption chiller in our country has been rapid development. However, with the development of refrigeration technology, especially the “energy-saving” calls, ordinary (single-effect) lithium bromide absorption chiller can not meet the needs of national economy development in our country, especially the development of textile industry. Because this model requires heating steam pressure should not be too high (usually 1 kg / cm ~ 2 gauge pressure), many users often need to first steam decompression, and then for the machine to use. This not only increases the throttling equipment, but also causes the energy loss in the throttling process, greatly reducing the utilization efficiency of thermal energy. In order to improve the utilization efficiency of thermal energy, in 1980, it was jointly designed by the 704 Research Institute of the Six Machinery Department and the General Machinery Research Institute of the First Machinery Department and was undertaken by Kaifeng General Machinery Plant,
