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...

This paper presents the performance prediction of a solar/gas driving double effect LiBr–H2O absorption system. In order to use auxiliary energy more effectively and be less dependent on solar irradiation, a new kind of solar/gas driving double effect LiBr–H2O absorption system is designed....

An adsorption cooling machine with LiCl/Silica gel–methanol was designed and tested, which can work for air conditioning and cold storage. The machine can be driven by low temperature heat source, such as solar energy and industrial waste heat. The composite adsorbent of LiCl/Silica gel has...

Two-stage air-cooled ammonia–water absorption refrigeration system could make good use of low-grade solar thermal energy to produce cooling effect. The system simulation results show that thermal COP is 0.34 and electrical COP is 26 under a typical summer condition with 85°C hot water...

One two-phase thermo-syphon silica gel-water solar adsorption chiller and LiBr-H2O absorption chiller with new medium CPC (Compound Parabolic Concentrator) solar collectors were investigated. The reliability of adsorption chiller can be improved, because there is only one vacuum valve in this...

In recent years, sorption processes are increasingly gaining attention in the field of TES (thermal energy storage), owing to their advantages of high storage density and no significant heat loss during storage process. In this paper, a novel three-phase sorption cycle is proposed and evaluated...

An air-cooled two-stage NH3-H2O absorption refrigeration system is proposed for potential application of residential small scale cooling system driven by solar heated hot water. It can reduce the initial fabrication and maintenance costs of both the solar collection system and the absorption...

This study reports the performance of a demonstrated 2304 m2 solar-heated greenhouse equipped with a seasonal thermal energy storage system in Shanghai, east China. This energy storage system utilises 4970 m3 of underground soil to store the heat captured by a 500 m2 solar collector in...

To solve the overheating problem caused by the solar radiation and to keep the indoor temperature and humidity at a proper level for plants or crops, cooling technologies play vital role in greenhouse industry, and among which evaporative cooling is one of the most commonly-used methods....

Generation temperatures from 110 °C to 140 °C are not enough to drive a double effect LiBr-water absorption cycle but too high for a single effect cycle under typical operating conditions. A novel LiBr-water absorption cycle which contains an AGX (absorber generator heat exchanger) is...
