一、绪言使用水—溴化锂的吸收式制冷机与具有相同用途的广泛使用的透平制冷机相比较,由于用热能作为动力源并依靠化学的循环来制冷,因此它不需要大规模的电力设备。此外,在夏天它还可以有效地利用暖气锅炉或利用废热。转动的只有泵,因此噪音小,运转简单。近年来其需要日益增加。面对这样的发展趋势, I. INTRODUCTION WATER - Lithium bromide absorption chillers do not require large-scale electrical equipment because they use thermal energy as a source of power and rely on a chemical cycle to cool, compared to the widely used turbochar with the same purpose . In addition, it can also effectively use heating boilers or waste heat in the summer. Only pump rotation, so the noise is small, simple operation. Its needs have been increasing in recent years. Faced with this trend of development,
