设计了两台具有分离式两相封闭热虹吸加热过程的吸附式制冷机，以提高传热性能并减少系统运动部件数量和系统尺寸。一台吸附式制冷机采用三效分离式两相闭式热虹吸加热/冷却设计;另一台采用分离式分离式两相闭式热虹吸加热和强制对流冷却设计。结果表明，压差回质过程可以提高制冷机的性能系数（COP）和制冷比（SCP）。采用分离式两相闭式热虹吸加热和强制对流冷却设计的系统更有吸引力，因为使用的移动部件更少，并且可以减小系统的尺寸。此外，吸附床的热传递设计为分离式热管，可避免来自热源或散热源（如重型废气或海水）的腐蚀问题。在额定工况下，蒸发温度、COP和SCP可达−21 °C、0.26和474 W kg−1。版权所有© 2015约翰威利父子有限公司.
Two adsorption refrigerators with separate type two‐phase closed thermosyphon heating processes are designed to improve the heat transfer performance and to reduce the system's moving parts number and system's size. One adsorption refrigerator uses the design of three‐effect separate type two‐phase closed thermosyphon heating/cooling; the other one uses the design of separated separate type two‐phase closed thermosyphon heating and force convection cooling. The results show that the coefficient of performance (COP) and specific of cooling power (SCP) can be improved because of the pressure difference mass recovery process. The system with the separate type two‐phase closed thermosyphon heating and force convection cooling design is more attractive because fewer moving parts are used and the system's size can be reduced for building. Moreover, the thermal transfer of the adsorption beds is designed as separate type heat pipe, which can avoid the problem of corrosion from heat or sink sources, such as heavy‐duty exhaust gases or seawater. Under the nominal working condition, the evaporating temperature, COP and SCP can reach −21 °C, 0.26 and 474 W kg−1. Copyright © 2015 John Wiley & Sons, Ltd.
