A novel model of the combined cycle of a solar-powered adsorption–ejection refrigeration system (CCSPAERS) is established. By analyzing the theory of this system and its thermodynamics, together with numerical simulation, it is found that it is a feasible method to overcome the intermittent...

Two different working pairs, one of them activated carbon–methanol and the other activated carbon–ethanol, are used in a solar ice maker to determine ice production and refrigerant criteria in desorption and adsorption processes under similar radiation energy and environmental conditions....

A uniform pressure model is presented to describe the heat and mass transfer in an adsorbent bed for a flat plate solar ice maker. This model accounts for heat and mass transfer in a porous bed in a two-dimensional transient process. An experiment has been conducted to validate this model and...

A detailed analysis and simulation of heat transfer of an evacuated tube for a solar-powered adsorption refrigerator, including inhomogeneous radiation heat transfer between its inner and outer tubes, two adjacent tubes in the group, the tube and back plate, sunlight reflection on back plate,...

This paper reviews the previous work on phase change cold storage for air-conditioning systems focusing on two aspects including phase change materials (PCMs) and applications. Besides the studies on phase change cold storage devices, the typical air-conditioning systems with cold storage are...

Solar powered solid desiccant cooling system is a good alternative to conventional vapor compression system. In this paper, a novel solar driven desiccant coated heat exchanger cooling (SDCC) system is proposed. In order to validate the feasibility of such system and to predict system...

Solar cooling technology is environmentally friendly and contributes to a significant decrease of the CO2 emissions which cause the green house effect. Currently, most of the solar cooling systems commonly used are the hot water driven lithium bromide absorption chillers. According to the...

As a simple and practical bioclimatic design methodology, solar chimneys are receiving considerable attention for reducing heat gain and inducing natural cooling or heating in both commercial and residential buildings because of their potential benefits in terms of operational cost, energy...

China has a big population and all countryside are being urbanized recently, more and more buildings are being built with careful considerations of energy saving. Building integrated energy systems are thought to be of priority importance. There are extended energy storage researches and...
