放射冷却式装置

Resumen de: JP2025097208A

【課題】比較的長期間に亘って、経時的に反射率が低下することを防止すると共に、表面（放射面）の耐摩耗性を維持しながらも、放射性能が低下しない放射冷却膜材を提供する。【解決手段】赤外放射層における放射面の存在側にシリカを主成分とするコート層を備え、コート層の層厚は、３０ｎｍ以上５００ｎｍ未満であり、コート層を生成するためのコート材料が、アルコール溶剤に粒状のシリカを分散させた混合物を乾燥させたものであり、コート層を形成するコート材料は、乾燥前の質量である加熱乾燥前質量のコート材料を２００℃で所定の判定加熱時間の間加熱したときに残る質量を第１残量質量とし、加熱乾燥前質量のコート材料を７００℃で判定加熱時間の間加熱したときに残る質量を第２残量質量としたときに、（第１残量質量－第２残量質量）／第１残量質量の値が、０．０５以上で且つ０．４５未満の条件を満たすものである。【選択図】図１

SOLAR COLLECTOR FOR A CURING KILN

Resumen de: WO2025133023A1

There is provided a solar collector (2) for a curing kiln (1) comprising one or more translucent sections which are arranged to allow the passage of solar radiation therethrough; one or more solar radiation absorbing sections (8) for absorbing solar radiation which has passed through the one or more translucent sections; and one or more air channels (40) formed between the one or more translucent sections and the one or more solar radiation absorbing sections (8). In a mode of operation, process air is arranged to pass through the one or more air channels (40) in order to be warmed. The or each translucent section comprises a first translucent layer (3), a second translucent (4) layer and a thermal insulation layer provided between the first translucent layer (3) and the second translucent layer (4).

SYSTEM AND METHOD FOR CALIBRATING IR CAMERAS MONITORING A SOLAR RECEIVER

Resumen de: EP4575430A1

The present invention relates to a thermal mapping, calibration and monitoring system for an outdoor thermal zone of interest, comprising :- the thermal zone of interest having a front side irradiated by a solar flux and a non-irradiated back side ;- a plurality of IR detection cameras presenting a field of vision and located each remotely from the thermal zone of interest ;- a weather station located on site providing weather parameters ;- a monitoring system ; and- communicating means between the IR detection cameras and the monitoring system ;wherein the system comprises means to communicate raw temperatures Traw measured by the IR cameras on the thermal zone of interest to the monitoring system and further calibrate the measurements in the monitoring system by taking into account the atmospheric transmittance τ and also the real emittance ε of the thermal zone of interest to correct the raw temperatures Traw, before using the corrected values in further monitoring calculations.

Resumen de: AU2023269059A1

A thermochemical oxidation reactor 11 operably extracts energy from solid solar thermochemical fuel 13. In another aspect, an oxidation reactor includes a main reactor chamber 15 and an extraction tube 17 connected to the main reactor chamber to directly draw hot gas therefrom. In still a further aspect, an oxidation zone 33 of a thermochemical oxidation reactor has an internal chamber 19 with a larger cross-sectional area 'A' as compared to internal cross-sectional areas 'B' and 'C' of adjacent recuperation and quenching zones 35 and 31 of the reactor.
