“…In other words, the refrigerant amount that can adsorbed/desorbed is increasing without increasing the temperature. Akahira et al [6,7] determined that the mass recovery cycle provides heat to the desorber and cooling to the adsober. They also reported that the cycle produces a better performance than that of conventional mass recovery without heating and cooling.…”

“…The performance of the adsorption refrigeration cycle can be enhanced by applying a mass recovery cycle during the adsorption cycle [6][7][8][9][10][11][12][13][14]. The mass recovery cycle is produced by interconnecting the two beds that depressurize and pressurize after the desorption and adsorption processes, respectively.…”

This paper presents the performance of an advanced cascading adsorption cycle that utilizes a driven heat source temperature between 90-130 ºC. The cycle consists of four beds that contain silica gel as an adsorber fill. Two of the beds work in a single stage cycle that is driven by an external heat source, while the other two beds work in a mass recovery cycle that is driven by waste heat of sensible and adsorption heat of the high temperature cycle. The performances, in terms of the coefficient of performance (COP) and the specific cooling power (SCP), are compared with conventional cascading-without-mass-recovery and single-stage cycles. The paper also presents the effect of the adsorbent mass on performance. The results show that the proposed cycle with mass recovery produces as high of a COP as the COP that is produced by the conventional cascading cycle. However, it produces a lower SCP than that of the single-stage cycle.

“…Conceptually, the pressure difference between two beds in the beginning of the process will causes refrigerant flows until a pressure balance is reached between the beds. Akahira et al [9,10] determined that the mass recovery cycle provides heating to the desorber and cooling to the adsober. They reported that the cycle produces better performance than that of conventional mass recovery without heating and cooling.…”

Abstract:The performance of an advanced three-bed adsorption chiller with a mass recovery cycle has been experimentally investigated in the present study. The temperature and pressure of various components of the chiller were monitored to observe the dynamic behaviour of the chiller. The performances in terms of the coefficient of performance (COP) and specific cooling power (SCP) were compared with a conventional single stage. The results show that the proposed cycle produces COP and SCP values superior to those of the conventional single stage cycle for heat source temperature below 75 °C.
