摘　　要：为了确定扩散吸收式制冷系统DAR(Diffusion Absorption Refrigeration System)的输入功率,本文建立了以氨-水-氦为工质的DAR系统,采用对比试验,用温度曲线描绘了在电加热和燃油两种加热方式下热源变化给系统带来的影响。实验表明,只有在短时间内精馏器入口温度达到最低发生温度140℃时,系统的工质才能达到正常喷发。因此,对于DAR系统必须匹配合适的输入功率。In order to fix on an appropriate input power of DAR,an experimental system which used NH3-H2O-He as woring fluids was set up. Then the temperature curves were used to describe the influence of heat source＇ change on the system both under the electric heating condition and kerosene heating condition. It indicated that the working fluids normally erupted when the temperature in dephlegmator reached 140℃. So the suitable input power is necessary for DAR.
