TL;DR: In this article, a model for a typical parabolic trough solar thermal power generation system with organic rankine cycle (PT-SEGS-ORC) was built within the transient energy simulation package TRNSYS, which is formed by integrating several submodels for the trough collector system, the single-tank thermal storage system, auxiliary power system and the heat-electricity conversion system.

TL;DR: In this article, a review of the advances in solar heat pump drying systems is presented, which indicated that for heat sensitive materials; improved quality control, reduced energy consumption, high coefficient of performance and high thermal efficiency of the dryer were achieved.
Abstract: Combining solar energy and heat pump technology is a very attractive concept. It is able to eliminate some difficulties and disadvantages of using solar dryer systems or solely using heat pump drying separately. Solar assisted heat pump drying systems have been studied and applied since the last decades in order to increase the quality of products where low temperature and well-controlled drying conditions are needed. This paper reviewed studies on the advances in solar heat pump drying systems. Results and observation from the studies of solar assisted heat pump dryer systems indicated that for heat sensitive materials; improved quality control, reduced energy consumption, high coefficient of performance and high thermal efficiency of the dryer were achieved. The way forward and future directions in R&D in this field are further research regarding theoretical and experimental analysis as well as for the replacement of conventional solar dryer or heat pump dryer with solar assisted heat pump drying systems and solar assisted chemical and ground source heat pump dryers which should present energy efficient applications of the technologies.

TL;DR: In this article, the authors consider cooling systems for residential and utility buildings in both South and North Europe and investigate the most promising alternatives when solar energy is to be used to supply the cooling demand of these buildings while the heat rejection temperatures are high.
Abstract: Solar energy can potentially contribute to 10% of the energy demand in OECD countries if all cooling and heating systems would be driven by solar energy. This paper considers cooling systems for residential and utility buildings in both South and North Europe and investigates the most promising alternatives when solar energy is to be used to supply the cooling demand of these buildings while the heat rejection temperatures are high. Both the solar electric and solar thermal routes are considered. The discussion considers both concentrating and non-concentrating thermal technologies. It is concluded that presently vapor compression cycles in combination with PV collectors lead to the economically most attractive solutions. The second best option are vapor compression cycles driven by electricity delivered by parabolic dish collectors and Stirling engines. The best thermally driven solution is the double-effect absorption cycle equipped with concentrating trough collectors closely followed by desiccant systems equipped with flat-plate solar collectors. Adsorption systems options are significantly more expensive.

05 Nov 1993TL;DR: In this paper, a hybrid combined cycle power plant including a solar central receiver for receiving solar radiation and converting it to thermal energy was proposed, which includes a molten salt heat transfer medium for transferring the thermal energy to an air heater.
Abstract: A hybrid combined cycle power plant including a solar central receiver for receiving solar radiation and converting it to thermal energy. The power plant includes a molten salt heat transfer medium for transferring the thermal energy to an air heater. The air heater uses the thermal energy to preheat the air from the compressor of the gas cycle. The exhaust gases from the gas cycle are directed to a steam turbine for additional energy production.
