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,...

The green buildings of Shanghai Research Institute of Building Science include an office building for the demonstration of public building and two residential buildings, which are for the demonstration of flat and villa, respectively. Here, a solar-powered integrated energy system including...

Experimental investigation and relevant analysis on a solar cell driven, thermoelectric refrigerator has been conducted. To make the device portable, daytime use and nighttime use of the refrigerator are treated in different ways. Solar cells are applied to power the refrigerator in the day....

A hybrid solar cooling system, which combines the technologies of rotary desiccant dehumidification and solid adsorption refrigeration, has been proposed for cooling grain. The key components of the system are a rotary desiccant wheel and a solar adsorption collector. The former is used for...

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...

Modern large and fast ocean fishing vessels include mechanical refrigeration, but all of them consume precious fuel or electricity to achieve refrigeration. Fishing vessels with tonnage at about 100 tons cannot attach compressor-icemaker onboard because of their small horsepower of diesel...

In order to study the refrigeration performances of the resorption refrigeration technology, the resorption working pair of BaCl2–MnCl2–NH3, which has the similar working requirements for the heat source and cooling source, and also could satisfy the similar refrigeration requirements with...

A new test method about the time constant of the solar collector has been presented in this paper. It is simple and has been validated through experiments. With the new method it is not necessary to adjust the inlet temperature of the transfer fluid as closely as possible to the ambient air...
