【摘要】 以单效溴化锂吸收式热泵为例,对系统进行热力计算。通过改变设计工况下某单一变量(驱动热源温度,热水进口温度,低温热源温度),分别分析了机组效率变化情况,得出热水出口温度与低温热源温度、驱动热源温度相互制约关系,即:不同低温热源下热水进、出口温度有最大值。不同驱动热源温度下热水出口温度有最大值。更多还原

【Abstract】 A single-effect lithium bromide absorption heat pump is taken as an example to calculate the thermal power of the system. By changing a single variable(driving heat source temperature, hot water inlet temperature, low temperature heat source temperature) under design conditions, the change of unit efficiency is analyzed respectively. The mutual constraints of the hot water outlet temperature, low temperature heat source temperature and the temperature of the driving heat source are obtained, that is, the hot water inlet and outlet temperatures have the maximum value under different low temperature heat sources; the hot water outlet temperature has the maximum value under different driving heat source temperatures.更多还原
