Methods and devices are presented that allow the harvest of electricity, heat and lighting simultaneously from a solar converter, often at less cost than conventional solar collectors. The converters use slats to intercept sunlight. Slat surfaces in the direct light path may be coated with photovoltaic (PV) material, or may be shaped to concentrate sunlight, allowing less PV material to capture reflected, concentrated light for improved economics. Forcing air flow past enclosed slats let the slats operate as PV heat sinks, heat absorbers, and heat exchangers capturing much of the solar energy that is not converted to electricity, as heat. Embodiments also allow passage of indirect light to supplement interior artificial lighting, often with positive aesthetic effects. These slatted apertures mitigate glare and overheating problems associated with typical skylights and some windows, allowing wider use as architectural elements. The devices also can be integrated into new building construction, and serve a dual purpose as building structural components.

An object of the present invention is to provide a conveyer oven having a high heat efficiency and excellent cooking performance. Foods F are carried into a heating chamber 10 by a conveyer 60 and conveyed to the upper portion of the heating chamber. While the foods F are conveyed at the upper portion of the heating chamber, an eject nozzle 45 blows hot air to the foods F and simultaneously foods F are surrounded with remaining hot air. When cooking is finished, the foods F are conveyed downward to be carried out from the heating chamber 10. Therefore, heat from a heating means 20 is used effectively for cooking, that means heat efficiency is improved, which reduces fuel cost. Moreover, since the foods F are surrounded with remaining hot air, the foods F are evenly heated all over, whereby cooking performance is improved.

A shaped body, particularly a sorbent shaped body, made of microporous and mesoporous adsorbents and of composite adsorbents, which serve to store useful heat and useful cold, comprises a reduced proportion of binding agents. The sorbent shaped bodies have non-uniformly distributed cavities in the form of vacuoles that form gap volumes, and are obtained by placing the solid pre-mixed constituents of the shaped body onto a porous or perforated support. After adding the binding agent, the process of pre-solidifying the binding agent ensues by the action of an external force field, and this force field results in the formation of the non-uniformly distributed cavities. The proportion of binding agent on the support, which depicts the wall of the shaped body, is higher than that inside the shaped body. An optimally possible combining of the reaction efficacy of modified alumosilicates and / or aluminum silicates with their fluidic action during the exchange of materials and heat with the aim of achieving high space-time yields while storing useful heat and useful cold is thereby achieved.

Chilling is produced from heat that is normally wasted in the economizer section of a steam boiler. A thermally-activated ammonia-water absorption chiller is powered by a heat recovery unit. The heat recovery unit supplies boiler exhaust heat to desorb the working fluid of the chiller. That can be directly, such that the heat recovery unit is a heat recovery vapor generator that can be colocated with an economizer, in parallel or series. The exhaust heat can alternatively be supplied to the AARC indirectly, via a heat transfer loop and a separate generator. The desorbed ammonia vapor is rectified, condensed, and then used to produce the chilling. The heat released in the chiller when low pressure ammonia vapor is re-absorbed is used to preheat the boiler feedwater.
