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,...

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...

Based on the heat and mass transfer model validated by experiment, the performance of the plate solar ice-maker is analyzed systemically with the opinion of two-type characteristic parameters, which includes parametric effects of adsorbent bed of solar ice-maker and outer parameters referring to...

NZEB (Net zero energy building) is regarded as an integrated solution to address problems of energy-saving, environmental protection, and CO2 emission reduction in the building section. NZEB could be even possible with electricity production if enough renewable energy could be used. Moreover,...

Solar energy is receiving much more attention in building energy systems in recent years. Solar thermal utilization should be based on integration of solar collectors into buildings. The facades of buildings can be important solar collectors, and, therefore, become multifunctional. In addition,...

The utilization of a composite sorbent (NaBr and expanded graphite) in chemisorption air conditioning systems driven by low-grade heat source, and in resorption systems with simultaneous heating and cooling effects was experimentally investigated using bench-scale prototypes. The mass of ammonia...

In this paper, the design of a new continuous solid adsorption refrigeration and heating hybrid system driven by solar energy was proposed, and its performance simulation and analysis were made under the normal working conditions. Some performance parameters of the system were obtained, and the...

An adsorption icemaker with energy storage system is proposed for the utilization of medium temperature solar energy. In this system, the solar energy collected by parabolic trough collector (PTC) was used to provide the heat source for the adsorption icemaker. The performance of the icemaker is...
