      abstract     = {Low‐grade heat is abundantly available below 100 °C,
                      whereas industry mainly needs heat above 100 °C. Thus,
                      the industry cannot directly utilize low‐grade heat to
                      save primary energy and emissions. Low‐grade heat can be
                      utilized by adsorption heat transformers (AdHTs); however,
                      closed AdHTs to upgrade heat above 100 °C are only
                      investigated by idealized steady‐state analyses, which
                      indicate the maximal theoretical performance. For evaluating
                      the performance achievable in practice, this work studies a
                      closed AdHT in a one‐bed configuration using dynamic
                      simulation. For the working pair AQSOA‐Z02/H2O, the
                      performance is optimized via the design of the adsorber heat
                      exchanger and the control of the AdHT cycle. When heat is
                      upgraded from 90 to 110 °C, releasing waste heat at
                      35 °C, the maximum exergetic coefficient of performance
                      (COPexergetic) is 0.64, and the maximum specific heating
                      power (SHP) is 590 W kg−1. The maximum SHP can
                      increase by $35\%$ when releasing waste heat at 25 °C.
                      Both performance indicators strongly depend on design,
                      control, and the available temperature of the waste heat.
                      Overall, AdHTs with optimized design and control are
                      promising to utilize low‐grade waste heat.},
