本文报道了英国一个采用热驱动吸收式制冷技术的行业的案例研究。对吸收式制冷机回收工业废热的系统性能进行了研究，并对热驱动吸收式制冷系统进行了经济性分析。结果表明，当蒸发温度为5°C时，发生器温度为60°C时，吸收式制冷机的最佳COP约为0.825;当蒸发温度为10°C时，发生器温度为55°C时，系统的最大COP可达0.86。在从废气中回收200 kWh的最佳操作条件下，吸收器和冷凝器的平均所需热负荷分别为190 kWh和175 kWh。当发电机温度为60°C时，吸收式制冷机的制冷量为172 W。经济分析表明，在英国工业应用中使用吸收式系统的平均投资回收期约为2.5年，每年最高的电费节省可高达每千瓦热输入105英镑。
This paper reports a case study on a UK industry using heat driven absorption refrigeration technology. The system performance of the absorption refrigerator to recovery the industry wasted heat and economic analysis using the heat driven absorption system have been conducted. Results indicates when the evaporating temperature is 5°C , the optimal COP of the absorption chiller is about 0.825 under 60°C generator temperature and the maximum COP of the system under 10°C evaporating temperature can be as high as 0.86 with 55°C generator temperature. Under the optimal operating condition to recover 200 kWh from exhaust gases, the average required heat load of absorber and condenser are 190 kWh and 175 kWh, respectively. When the generator temperature is eat at 60°C , the cooling production from the absorption chiller is 172 W. The economic analysis suggests the average payback period to use the absorption system for UK industry application is about 2.5 years and the highest annual electricity cost saving can be as high as £105 per kw thermal heat input.
