“…Many reports on building systems using PCMs have been published, and recent advances are summarized in several review papers [9][10][11][12][13][14][15]. In addition, specialized experimental and analytical technologies for PCMs have been developed [16,17]. These technologies can further the application of PCMs in building materials by accelerating their practical implementation from labscale experiments.…”

a b s t r a c tWe developed shape-stabilized phase change composites (PCCs) for building materials with high heatstorage density by vacuum impregnation of the phase change material (PCM) octadecane into mesoporous SiO 2 . We examined the effects of the average pore size of mesoporous SiO 2 on the melting point and latent heat of the PCCs. Cyclic tests of melting and freezing were performed to evaluate leakage and degradation of the PCCs. The thermophysical properties of the PCCs were measured by differential scanning calorimetry, and the following results were obtained: (1) The impregnation ratio of the composites was above 0.95; therefore, almost all pores were completely filled with PCM. (2) The melting point of the PCMs decreased with decreasing average pore diameter, and the melting point was established as a function of average pore diameter from the Gibbs-Thomson equation, taking into account the existence of a nonfreezing layer on the surface of the pore wall. (3) The octadecane/mesoporous SiO 2 composites retained the full amount of impregnated PCM, even after cyclic heating and cooling.

“…The cooling energy efficiency ratio EER is determined in other way than in the case of other refrigeration systems, in which there is constant heat flux in all parts of the apparatus (Cyklis, Janisz 2015;Fernández et al 2015;Jaworski et al 2016;Kuczyński et al 2013). In the case of the adsorption refrigeration unit there should be used heat instead of the heat capacity (Eq.…”

Abstract. Adsorption refrigeration systems, as opposed to absorption type operate in a cyclic manner. The result is that at the beginning of each process must be fed into the adsorber state in which they will adsorb or desorb a refrigerant. In the case of two adsorbers at the start of a cycle, the one of the adsorber must be refrigerated while the second has to be heated. These processes are causing unnecessary energy loss. The aim of the work is to show how these processes can be connected and the heat received from one adsorber is transported to another adsorber. As part of the study, the heat and mass recovery processes will be considered. It turns out that in the thermal wave type systems, it is possible to recover more than 25% of the energy lost to bring the adsorber to the states in which they will operate efficiently to desorb and adsorb refrigerant. That is, it is possible to improve the efficiency of the adsorption refrigeration unit using the proposed improvements.
