Quin \u00e9s el millor m\u00e8tode per refrigerar una casa passiva en clima c\u00e0lid-temperat?<\/strong><\/p>\n

En aquest post\u00a0‘Els 3 sistemes de refrigerar casa teva passiva i preu’, trobar\u00e0s els nostres pros i contres dels millors 3 sistemes per refrigerar amb baix consum.
\nEn resum, aquest post t’explico la manera m\u00e9s eficient de refrigerar una casa passiva (preus 2021).<\/p>\n

Per si encara no ens coneixes, em presento, s\u00f3c l’Esther Rovira, fundadora d’ERA architects, arquitecta a Barcelona<\/a> i passive house designer per a cases passives, cases eficients i cases positives a Barcelona i Catalunya.
\nEspero que t’ajudi!<\/p>\n

 <\/p>\n

1) Splits directes un a un
\nEl sistema que funciona millor per refrigerar una casa passiva, \u00e9s el convectiu a trav\u00e9s de la recirculaci\u00f3 de l’aire interior.
\n\u00c9s a dir, els splits de paret que ja coneixes (s\u00ed, aquells que tenen associada una m\u00e0quina externa per aparell).
\nMalauradament, els splits interiors combinats amb una sola m\u00e0quina exterior, segueixen sent cars i no tan eficients.
\nPer a un pis de 90m2 a Barceleona ciutat i 5 Splits (i 5 m\u00e0quines exteriors), pots comptar a partir de 8.500\u20ac+iva en endavant.
\nEl problema daquesta opci\u00f3 \u00e9s on poses tanta m\u00e0quina?
\nCom ja sabr\u00e0s, moltes comunitats de ve\u00efns no els deixen col\u00b7locar a coberta i en fa\u00e7ana est\u00e0 prohibit (almenys a Barcelona).<\/p>\n

2) Splits per conductes
\n\u00c9s el sistema seg\u00fcent m\u00e9s efica\u00e7 \u00e9s el mateix per\u00f2 repartint l’aire per conductes.
\nTot i no ser tan efica\u00e7os, es poden inserir al fals sostre per a una millor integraci\u00f3 est\u00e8tica.
\nAquest sistema \u00e9s m\u00e9s car que l’anterior.
\nPer a un pis de 90m2 a Barcelona ciutat i 5 Splits, pots comptar a partir de 10.000\u20ac+iva en endavant.<\/p>\n

El pitjor d’aquests dos sistemes \u00e9s que utilitzen gas refrigerant contaminant.
\n\u00c9s important preguntar al teu instal\u00b7lador, quin gas utilitza.
\nI en mesura del que puguis promoure que el teu instal\u00b7lador utilitzi gas R32.
\nTamb\u00e9 podeu fer seguiment d’altres sistemes que aviat evolucionaran a base de gas prop\u00e0, hidrogen, biog\u00e0s o Co2.<\/p>\n

3) Bomba de calor-fred
\nAquest sistema convectiu en ciruit dexpulsi\u00f3 pot funcionar per a un apartament de de fins a 100m2, per\u00f2 no \u00e9s lopci\u00f3 m\u00e9s eficient.
\nEn cap cas funcionar\u00e0 per a cases m\u00e9s grans de 200m2 ja que no pot renovar tant volum d’aire per als nivells de confort necessaris.
\nA m\u00e9s, cal a\u00efllar els conductes per evitar la condensaci\u00f3 i que et plogui dins de casa.
\nAquest \u00e9s el sistema m\u00e9s econ\u00f2mic.
\nPer a un pis de 90m2 a Barcelona ciutat, podeu comptar a partir de 6.000\u20ac+iva en endavant.
\nPots afegir 1.500\u20ac+iva per automatitzar termoestats i regilles al teu m\u00f2bil.<\/p>\n

 <\/p>\n

La meva recomanaci\u00f3 professional:
\nAl nostre estudi d’Arquitectura a Barcelona recomanem separar la ventilaci\u00f3 mec\u00e0nica de doble flux de la climatitzaci\u00f3 per aire.
\nTamb\u00e9 treballar amb conductes de ventilaci\u00f3 amables per treballar amb cabals m\u00e9s fluids.<\/p>\n

Una an\u00e8cdota:
\nEn altres posts hem recomanat l’aerot\u00e8rmia per a calefacci\u00f3 i generaci\u00f3 d’ACS.
\nB\u00e9, doncs, per refrigerar i generar aigua calenta, ens planteja problemes. T’ho explico millor amb un exemple:
\nImagina que arribes de la platja a les 13:30, et vols enganxar una dutxa per treure’t la sal abans de dinar.
\nAix\u00f2 provoca que el sistema de refrigerar pari de fer fred per generar aigua calenta per a la dutxa.
\nI quan acabes la teva dutxa; el sistema pot trigar unes hores a tornar a generar fred i refrigerar.
\nResultat: quan t’acabes el segon Gin Tonic a les 16:30 t’est\u00e0s arrufant a casa teva passiva super eficient (b\u00e9, potser tamb\u00e9 t’has passat amb el Gin…).<\/p>\n

Espero que aquesta info t’ajudi en la teva\u00a0aventura.
\nFins al proper post!<\/p>\n
