High-efficiency ventilation and heating systems by means of solar air collectors for industry building refurbishment

Solar Air Heating and Ventilation in Buildings: A Key Component in the Forthcoming Renewable Energy Mix

“…It is instructive to review the outcomes of a3 -month energy metering of the heat actually generated by a1 3.1 2.2 m 2 (width height)t ranspired solar air collector installed in 2013 on the south faÅadeofatest building in Lucerne,corresponding to Switzerlandsa verage-sized industrial building with thermally insulated roof and walls (useful floor area: 300 m 2 ;h eight:8 .2 m). [26] Them easurements lasted from November 27th, 2013 to February 28th, 2014, and the results were unequivocal. Thet emperature of the air delivered by the unglazed collector typically was 30 8C, with typical values of thermal efficiency primarily depending on irradiance,o utside temperature,a ir volumef low,a nd wind speeda nd direction, reaching6 0%,w hich is in good agreement with previous results.…”

“…It is instructive to review the outcomes of a 3‐month energy metering of the heat actually generated by a 13.1×2.2 m 2 (width×height) transpired solar air collector installed in 2013 on the south façade of a test building in Lucerne, corresponding to Switzerland's average‐sized industrial building with thermally insulated roof and walls (useful floor area: 300 m 2 ; height: 8.2 m) . The measurements lasted from November 27th, 2013 to February 28th, 2014, and the results were unequivocal.…”

“…When, in winter, the need of hot air increases, the availability of solar radiation decreases, even though the vertical position of the solar collector augments winter production and partly compensates for the seasonal offset . On the cloudiest days, however, the solar air collector will not even begin functioning, as reported for example in the 3 months testing study of Sicre and co‐workers describing the performance of the unglazed solar collector in Switzerland …”

“…[29] On the cloudiest days,h owever, the solar air collector will not even begin functioning, as reportedf or example in the 3months testing study of Sicre and co-workers describing the performanceo ft he unglazed solar collector in Switzerland. [26] This means that solar air heatingc annot be adapted as the only space heatingt echnology,a nd that it will be especially usefuli nb uildings with good insulation with low energyr equirements( heating requirement < 50 kWh m À2 of living area per year),s uch as those originally built in Canada.I n Europe,t ens of thousand of buildings already exist with < 10 kWh m À2 heatingr equirement, whereas new legislation [30] requiring all new buildings( and all those undergoing major renovation)t ob en early zero-energy by the end of 2020 (and all new public buildings nearly zero-energy by 2018), opens the route to wide adoption of solar air heating as as pace heating technology,e speciallyu seful in the transitionalm onths during spring and autumn. Furthermore,a t lower latitudes such as in southern European countries, where the availability of sun radiation is much higher, also duringw inter, solara ir heating may well emerge as ak ey technology in the forthcomingfully renewable energy mix.…”

The Potential of Solar Air Heating in the Turkish Industrial Sector

“…Despite the fact that there are many TSC installations across Europe, there is a significant lack of independently tested monitoring data of TSC performance available for different sites, as mentioned by various researchers, such as Brown et al [14] in UK and Sicre and Baumann [19] in Switzerland. The current study provides transpired solar collector researchers with yet missing information by presenting simulated results different Turkish climatic zones compared to data from the monitored TSC system of an industrial building near Istanbul.…”
