本文对太阳能高效平板集热器与热水型一级溴化锂吸收式制冷机及热水型两级溴化锂吸收式制冷机组成的空调系统进行了计算分析。结果表明 ,在热水温度为 82 - 95℃的范围内 ,太阳能一级溴化锂吸收式制冷系统具有较高的效率 ,但系统效率随热源温度的下降而急剧降低 ;在热源温度为 65- 82℃的范围内 ,太阳能两级溴化锂吸收式制冷系统具有较突出的优越性 ,系统效率几乎不随热源温的变化而变化。因此 ,两级溴化锂吸收式制冷机与太阳能平板集热器有比较好的匹配性能。
In this paper, the calculation and analysis of the solar air-conditioning flat-type collector and hot water type lithium bromide absorption chiller and hot water two-stage lithium bromide absorption chiller are carried out. The results show that the first grade lithium bromide absorption refrigeration system has higher efficiency in the range of 82 - 95 ℃, but the system efficiency decreases sharply with the decrease of heat source temperature. When the heat source temperature is 65-82 ℃ Of the range, the solar two-stage lithium bromide absorption refrigeration system has more prominent advantages, the system efficiency almost does not change with the heat source temperature changes. Therefore, the two lithium bromide absorption chiller and solar panel collector has better matching performance.
