摘要
分析了温度参数对升温型溴化锂吸收式热泵性能系数的影响,通过对升温型溴化锂吸收式热泵建立数学模型,得到在相同工况条件下,发生温度的变化对系统性能系数的影响程度最大,但小于吸收温度和冷凝温度对系统性能系数影响程度之和。而随着发生温度的升高,它自身对系统性能系数的影响程度越来越弱。
The mathematical model of absorption heat transformer operating with water/lithium bromide was built. Influece of temperature to coefficient of performance of absorption heat transformer operating with watere lithium bromide was analyzed. It is shouwed that the influence degree of generator temperature to coefficient of performance was the biggest, but smaller than the sum of influence degree of absorber and condenser temperatures in the same operating mode. As the generator temperature heightened, the influence degree to the coefficient of performance of the system would smaller and smaller.
