Ventilation must remove moisture, not just heat, and the make-up air it pulls in is expensive to condition. The right air-to-air recovery strategy reclaims both the sensible and latent energy from the exhaust and pre-heats the incoming air. This article covers why pools are an energy nightmare, the recovery architecture, material choices and sizing.<\/p>\n<h2>Why pools are an energy nightmare<\/h2>\n<p>L'evaporation de la surface d'eau ouverte est implacable ; une piscine de 25 m peut evaporer des centaines de litres par jour, et cette vapeur transporte de grandes quantites de chaleur latente. Le batiment doit etre ventile assez fort pour maintenir l'humidite interieure sous environ 60 % HR afin que la condensation n'attaque pas les fenetres, l'acier et les accessoires. Mais evacuer cet air humide jette ses deux energies, chaleur et humidite, et l'air de renouvellement doit etre chauffe (et en hiver, souvent dehumidifie indirectement) avant d'entrer. <a href=\"https:\/\/www.26yc.com\/fr\/hvac-heat-recovery-air-to-air-en\/\">Recuperation air-air<\/a> intercepte l'echappement et recupere une grande part de cette energie perdue.<\/p>\n<h2>Recovery architecture<\/h2>\n<p>The standard approach places a plate or wrap-around coil ahead of a heat-pump dehumidifier. The recovery device pre-warms the make-up air with the exhaust and, in an enthalpy design, also transfers moisture, reducing the dehumidifier&#8217;s load. A wrap-around (run-around) coil loop is attractive in pools because the supply and exhaust are fully isolated \u2014 useful where the exhaust is chlorine-laden and you do not want any path back to supply. Pair the recovery with a dedicated pool dehumidifier so the system controls humidity first and recovers energy second.<\/p>\n<h2>Material choices<\/h2>\n<p>Le chlore et les produits chimiques associes sont corrosifs, si bien que le choix des materiaux decide la duree de vie. L'acier nu dans le courant d'air est une erreur ; le PVC, le titane ou les coeurs en aluminium coate resiste bien mieux a l'environnement. Le coeur doit etre drainable afin que la condensation ne stagne pas et ne developpe une biofilm, et l'echangeur doit etre accessible pour un lavage periodique. Notre <a href=\"https:\/\/www.26yc.com\/fr\/heat-exchanger-selection-guide-en\/\">guide de s\u00e9lection<\/a> compare les options aluminium, inox et PVC face a la chimie de l'air.<\/p>\n<h2>Sizing rules<\/h2>\n<p>Dimensionnez les trajets d'echappement et de renouvellement au taux d'evaporation de la piscine a sa temperature de conception et sa charge de baigneurs, puis dimensionnez le coeur de recuperation pour le debit resultant et la difference de temperature hivernale. Visez 60-70 % d'efficacite sensible sur la plaque, le deshumidificateur g\u00e9rant la charge latente restante. Rappelez-vous le double prix : le confort des occupants et la protection de la structure. Une recuperation sous-dimensionnee laisse la condensation non controlee ; une recuperation sur-dimensionnee ajoute une perte de charge et un cout de ventilateur. Une conception equilibree s'amortit generalement en deux a quatre ans via la reduction de la charge de chauffage de piscine et de conditionnement de l'air de renouvellement.<\/p>\n<h2>Build a pool recovery system with QIYU<\/h2>\n<p>QIYU fournit des coeurs air-air a plaques et a bobines a recirculation resistants a la corrosion pour natatoriums, avec des conceptions drainables et des materiaux adaptes a l'air chlor\u00e9.

Ventilating that moisture away throws away both sensible and latent energy, and the make-up air is expensive to condition.<\/p>\n<p class=\"yc-faq\"><strong>Q: What recovery architecture works?<\/strong><br \/>A plate or wrap-around coil ahead of a heat-pump dehumidifier pre-warms make-up air with the exhaust, and an enthalpy design also transfers moisture, reducing the dehumidifier load. A wrap-around coil fully isolates the chlorine-laden exhaust.<\/p>\n<p class=\"yc-faq\"><strong>Q: Which materials resist the pool environment?<\/strong><br \/>Corrosion-resistant cores such as polymer, epoxy-coated aluminium or stainless paths are specified because the warm, chlorinated, high-humidity airstream quickly attacks bare metals.<\/p>\n<p class=\"yc-faq\"><strong>Q: How is the recovered energy used?<\/strong><br \/>Recovered energy pre-heats and partially dehumidifies incoming air, cutting the heating and dehumidification duty and protecting the building fabric from condensation.<\/p>\n<div class=\"yc-related\">\n<h3>Articles connexes<\/h3>\n<ul>\n<li><a href=\"https:\/\/www.26yc.com\/fr\/heat-recovery-payback-calculator\/\" title=\"Estimer le retour sur investissement de la recuperation de chaleur : une demarche pratique avec calculateur\">Estimer le retour sur investissement de la recuperation de chaleur : une demarche pratique avec calculateur<\/a><\/li>\n<li><a href=\"https:\/\/www.26yc.com\/fr\/laboratory-exhaust-heat-recovery\/\" title=\"Laboratory Fume Hood Exhaust Heat Recovery: Rotary Wheels vs Plates for Make-Up Air\">Laboratory Fume Hood Exhaust Heat Recovery: Rotary Wheels vs Plates for Make-Up Air<\/a><\/li>\n<\/ul>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>A natatorium is one of the toughest HVAC environments in any building: warm water evaporates continuously, loading the air with vapour that condenses on every cold surface and rots the structure if ignored.
