这里提供了一种可连续提供约650mW制冷量(20～30K)的氢吸收式闭式循环制冷系统。这种系统的原理如图1所示。低温段排出的氢在约6大气压(600kPa)的驱使下,通过一连串的热交换器,复热到室温,进入三台LaNi~5吸附器的其中之一(图2),氢被LaNi~5吸收。然后,用电加热器(或通过一台热交换器获得的余热)将LaNi~5加热到100℃,使得LaNi~5在40大气压(4MPa)下解析出氢气。
There is provided a hydrogen absorption closed-cycle refrigeration system capable of continuously providing a cooling capacity of about 650 mW (20 to 30 K). The principle of this system is shown in Figure 1. Hydrogen discharged from the low temperature section is heated to room temperature by a series of heat exchangers driven by about 6 atm (600 kPa) into one of three LaNi-5 adsorbers (Fig. 2). The hydrogen is replaced by LaNi-5 absorb. The LaNi ~ 5 was then heated to 100 ° C with an electric heater (or residual heat obtained through a heat exchanger) to allow LaNi ~ 5 to resolve the hydrogen gas at 40 atm (4 MPa).
