“…The performance of the adsorption refrigeration cycle can be enhanced by applying a mass recovery cycle into the adsorption cycle [9][10][11]. The mass recovery cycle is produced by interconnecting the two beds for depressurizing and pressurizing after desorption and adsorption processes, respectively.…”

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.

“…For the same reason, various other adsorbent/refrigerant combinations have been investigated for their adsorption capabilities. The performance of silica gel/water [3][4][5], activated carbon/methanol [6][7][8], and zeolite/water [10][11] has been analyzed. However, silica gel/water is already widely used as an adsorbent/refrigerant combination in adsorption systems because silica gel can be regenerated at a relatively low temperature compared to that of other adsorbents, and it also has a high latent heat of evaporation.…”

A numerical investigation of the double-effect adsorption refrigeration cycle is examined in this manuscript. The proposed cycle is based on the cascading adsorption cycle, where condensation heat that is produced in the top cycle is utilized as the driving heat source for the bottom cycle. The results show that the double-effect cycle produces a higher coefficient of performance (COP) as compared to that of the conventional single-stage cycle for driving temperatures between 100 °C and 150 °C in which the average cycle chilled water temperature is fixed at 9 °C . Moreover, the COP of the double-effect cycle is more than twice that of the single-stage cycle when the temperature reaches 130 °C . It is also observed that the adsorbent mass ratio of the high temperature cycle (HTC) to the low temperature cycle (LTC) affects the performance of the double-effect adsorption refrigeration cycle.

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.
