After presenting the most promising continuous adsorption cooling topology for air‐conditioning of a passenger cabin, a transient, 3D model is proposed, based on a modified linear driving force approach, to simulate an adsorption process in a SAPO‐34‐coated open‐celled aluminum foam. The simulation is executed in ANSYS CFX 15.0 and the additional model equations are implemented through the CFX expression language. As a result the influence of the pore diameter onto the system simulation and the mass transport limitation is shown and the sensitivity concerning the pressure in the gas phase adsorption is confirmed.

“…There has also been a search for alternatives to vapor‐compression technology ( Figure 1 ), with the current unprecedented degree of urgency pushing researchers to develop some radical technologies . One example is absorption and adsorption refrigeration, which holds a lot of promise when waste or renewable heat is available. Other thermally driven alternatives are ejector refrigeration systems, which, like sorption technologies, perform work without moving parts based on low‐temperature thermal resources .…”

The need for energy‐efficient and environmentally friendly refrigeration, heat pumping, air conditioning, and thermal energy harvesting systems is currently more urgent than ever. Magnetocaloric energy conversion is among the best available alternatives for achieving these technological goals and has been the subject of substantial basic and applied research over the last two decades. The subject is strongly interdisciplinary, requiring proper understanding and efficient integration of knowledge in different specialized fields. This review article presents a historical and up‐to‐date account of the energy‐related applications of magnetocaloric materials and information about their processing and magnetic fields, thermodynamics, heat transfer, and other relevant characteristics. The article also discusses the conceptual design of magnetocaloric refrigeration and power generation systems and some guidelines for future research in the field.

“…In addition to environmental benefits and energy saving, these systems have many other advantages such as lack of moving parts, low operating costs, vibration-free operation and simple control [4,5]. These features make them suitable for applications in automotive air conditioning systems using waste heat from the engine operation without losing mechanical energy, which can also reduce the carbon footprint [6].…”

Adsorbent bed design and performance strongly affect the overall performance of adsorption systems. In the present study, an analytical model was developed to determine the optimum geometrical and thermal parameters of a flat tube-fin adsorbent bed to reach the maximum system performance. This types of heat exchangers offer substantial reduced in weight, cost, volume and thermal conductivity, which can make them a good choice for adsorbent beds in automobile applications. Results showed that the overall thermal conductance of the bed and the maximum practical specific cooling capacity increased when reducing in flat tube thickness and fin pitch as well as by increasing in fin thickness and water channel wall thickness. The specific thermal conductance increased by 2.5% when reducing the channel pitch from its design value to a minimum permissible (0.004m). From thermal parameters that have been studied, the adsorbent thermal conductivity is the most sensitive parameter to the specific thermal conductance in beds. The system performance also significantly enhanced by reducing the mass of the metal 2 bed and the heat transfer fluids as well as the desorption heat of the selecting working pair.
