Regenerative adsorption heat pumps: Optimization of the design

Entropic analysis of adsorption open cycles for air conditioning. Part 1: first and second law analyses

“…Most of the times, the zeolite#water pair is used in cooling systems with closed cycle where the water vapour is at low pressure, e.g. some kilopascal (Grenier et al, 1988;Douss et al, 1988;Ben Chanaa et al, 1991;Zhu et al, 1992;van Benthem et al, 1995;Hajji and Khallou", 1995;Guilleminot et al, 1998). Some solar systems operated with the silicagel#water pair have also been tested (Dupont et al, 1994;Gurgel and Kluppel, 1996).…”

Selective water sorbents for multiple applications, 7. Heat conductivity of CaCl2−SiO2 composites

“…The calculations were performed using the following parameters: hw = 1500 W/m e K, hf = 1000 W/m e K, negligible Sin/kin, S. In order to have an idea about the quantitative influence of the ~ value on the machine performance, the specific power in the heating mode has been calculated using a simulation program developed in Ref. [15]. The model refers to an adsorption heat pump composed of two reactors with a uniform temperature distribution and operation with the internal heat recovery.…”

Modelling and Optimization of an Adsorption Cooling System for Automotive Applications

“…As expected, these models can be used to obtain a theoretical limit regarding performance and capacity of a system, but are not able to identify causes of poor performance when examining experimental data. Several thermodynamic models can be found in the literature [33,34,35,36].…”

“…Cacciola et al [34] The optimization of the design of an adsorption heat pump based on thermodynamic analysis was investigated by Cacciola et al [35] and Benthem et al [36].…”

“…Benthem et al [36] performed an optimization study of the design of a zeolitewater adsorption heat pump. The bed was heated by using oil from a boiler and cooled by using an external heat exchanger.…”
