为了确定哪种热回收方法在性能系数（COP）和功率密度（机器的每单位质量或体积的功率输出）之间给出上级折衷，进行了多床和热波吸附循环的计算建模。该模型进行了活性炭-氨对与高功率密度板式换热器型发生器。发现多床循环在COP和功率密度之间给出了上级权衡，因此推荐超过热波循环。主要应用被认为是燃气热泵，它被发现，该技术与竞争系统相比毫不逊色。
Computational modelling of multiple-bed and thermal wave adsorption cycles is carried out in order to determine which method of heat recovery gives the superior trade off between coefficient of performance (COP) and power density (the power output per unit mass or volume of machine). The modelling is performed for the activated carbon-ammonia pair with a high power density plate heat exchanger type generator. It is discovered that multiple-bed cycles give a superior trade-off between COP and power density and are therefore recommended over thermal wave cycles. The principal application is considered to be a gas fired heat pump and it is found that the technology compares favourably with competing systems.
