L\u2019alumnat de 3r d\u2019ESO de l\u2019institut Joaquim Blume, a principis del mes de mar\u00e7, va realitzar una visita als col\u00b7lectors solars de la resid\u00e8ncia. Es tracta d\u2019una activitat que es porta a terme dins de l\u2019\u00e0rea de geografia. Els aprenentatges de l\u2019alumnat es recullen en l\u2019informe que podeu llegir tot seguit.<\/p>\n

L\u2019edifici de la Resid\u00e8ncia Joaquim Blume t\u00e9 una capacitat per a 129 residents i una demanda d\u2019aigua sanit\u00e0ria de 3000 litres\/dia. Els mesos de juliol, agost i setembre es necessita menys aigua, entre 500 i 2000 litres\/dia (depenent del mes).<\/p>\n

Les plaques solars de la marca BAXI, ubicades al terrat de l\u2019edifici de la resid\u00e8ncia i amb una superf\u00edcie d\u20191,89 m2<\/sup> per m\u00f2dul, s\u2019encarreguen d\u2019escalfar tota l\u2019aigua que cal per a tota la resid\u00e8ncia fins als 60 o<\/sup>C , ja que aquesta \u00e9s la temperatura apta per a l\u2019\u00fas sanitari.<\/p>\n

Aquestes plaques estan formades per unes plaques de vidre, una part negra i un sistema intern per on circula l\u2019aigua. Estan orientades cap al sud-oest, per\u00f2 adaptades a la forma de l\u2019edifici per evitar que ocupin espai innecessari. Aix\u00f2 provoca que a les primeres hores del dia, el sistema d\u2019escalfament no sigui tan efectiu com a les primeres hores de la tarda.<\/p>\n

Perqu\u00e8 l\u2019aigua s\u2019escalfi passa des del primer panell fins a l\u2019\u00faltim, tot i que varia el ritme segons la llum solar del dia. Si la radiaci\u00f3 solar \u00e9s m\u00e9s intensa, l\u2019aigua augmenta la velocitat amb la qual es mou. En canvi, si \u00e9s un dia ennuvolat i, com a conseq\u00fc\u00e8ncia hi arriba menys radiaci\u00f3 solar, l\u2019aigua circula m\u00e9s lenta per poder arribar als 60 o<\/sup>C.
\nL\u2019aigua escalfada passa per uns captadors solars i transfereix l\u2019energia mitjan\u00e7ant un serpent\u00ed interior que escalfa dos dip\u00f2sits acumuladors de 1.500 litres de capacitat cadascun, situats a la sala de calderes. En aquestes calderes, l\u2019aigua pot arribar fins als 60o<\/sup>C i es barreja amb aigua freda, d\u2019aquesta manera es pot enviar als vestidors mitjan\u00e7ant un sistema de bombes, col\u00b7lectors i canonades. Tota la instal\u00b7laci\u00f3 est\u00e0 regulada per un sistema que procura mantenir els diferents par\u00e0metres (temperatura, cabals…) dins d\u2019uns determinats intervals, amb la finalitat d\u2019aconseguir unes condicions de confort amb el m\u00e0xim aprofitament d\u2019energia.<\/p>\n

Perqu\u00e8 el sistema no es faci malb\u00e9, cal tapar les plaques durant els mesos de m\u00e9s radiaci\u00f3 solar (agost). De tant en tant, s\u2019ha de comprovar que l\u2019aigua passi a la velocitat adequada, per tal de conservar les canonades en bon estat.<\/p>\n
