“…The performance limitations of adsorption cycles with different adsorbates for solar cooling were investigated by Critoph, who concluded that, in general, activated carbon-methanol combination was preferable for solar cooling, giving the best COP in a single-stage cycle [5]. There are other reasons that make activated carbonmethanol pair more attractive for use in solar cooling:…”

During the last 20 years, interest in the closed adsorption heat pump and refrigeration systems has increased steadily. In this paper, consideration is given to aspects of adsorption refrigeration in terms of existing materials used in adsorption refrigeration, heat transfer characteristics of materials, and cost of materials and manufacturing. The heat and mass transfer play very important roles in improving the cycle performances and their optimization is one of the technological challenges in developing adsorptionrefrigeration systems. In order to optimize an adsorber it is essential to control unconsolidated adsorbers; coated adsorbers and consolidated adsorbers. The paper is a general review of adsorption refrigeration technology and provides information of value to those involved with heat pump and refrigeration systems technology.

“…Recently, Tamaniot-Telto and Critoph [12] investigated the thermo-physical properties of two types of monolithic activated carbons with an intention to design and fabricate a high performance generator for sorption refrigeration systems and heat pumps using ammonia as refrigerant. It was found that, reduction in volume from granular bed to monolithic bed was up to 50%, which could lead to a substantial economic gain.…”

For solar thermal utilization, one of the main objectives is to improve system performance for reducing collector areas. In this article, the optimum heat source temperature for maximizing solar cooling coefficient of performance (COP) of a novel solar adsorption air-conditioning system (SAACS) is investigated theoretically. A mathematical model for the energy balance of the SAACS is developed. The optimum heat source temperature for the SAACS with two types of solar collector is determined by numerical simulation. The simulation results reveal that the solar cooling COP of the SAACS with evacuated tube collector can exceed 0.25 with optimum heat source temperature. Moreover, the SAACS can run with high efficiency in a wide heat source temperature range when the solar radiation is more than 700 W/m 2 .
