La recuperaci\u00f3n sensible solo mueve calor; la recuperaci\u00f3n de entalp\u00eda, o total, tambi\u00e9n mueve humedad, lo cual es valioso en climas h\u00famedos.<\/p>\n<h2>Two Common Designs<\/h2>\n<ul>\n<li>Intercambiadores de placas: n\u00facleos fijos de aluminio o pol\u00edmero, simples y confiables, buenos cuando los dos flujos deben permanecer totalmente separados.<\/li>\n<li>Ruedas rotativas: una rueda giratoria con recubrimiento desecante que almacena y libera calor y humedad; alta eficiencia pero con algo de fuga cruzada entre flujos.<\/li>\n<\/ul>\n<h2>Where It Pays Off<\/h2>\n<p>La recuperaci\u00f3n es m\u00e1s valiosa en edificios con altas tasas de renovaci\u00f3n de aire: escuelas, oficinas, hospitales y laboratorios. En clima fr\u00edo, recuperar el calor del escape puede recortar la demanda de calefacci\u00f3n en un tercio o m\u00e1s.<\/p>\n<h2>Sizing and Control Tips<\/h2>\n<ul>\n<li>Ajuste la efectividad al clima: mayor en regiones fr\u00edas, equilibrada contra la energ\u00eda de los ventiladores.<\/li>\n<li>Use amortiguadores de bypass en temporadas intermedias para no bloquear el free-cooling.<\/li>\n<li>Especifique protecci\u00f3n contra heladas, como precalentamiento o recirculaci\u00f3n de escape, para sitios muy fr\u00edos.<\/li>\n<li>Mantenga los filtros limpios; el ensuciamiento es la causa principal de p\u00e9rdida de rendimiento.<\/li>\n<\/ul>\n<h2>Bottom Line<\/h2>\n<p>Para la mayor\u00eda de los edificios ventilados, la recuperaci\u00f3n aire-aire es una de las mejoras de energ\u00eda de retorno m\u00e1s corto disponibles.

Total, or enthalpy, recovery also transfers moisture, which is valuable in humid climates where both temperature and humidity loads are high.<\/p>\n<p><strong>Which design suits buildings better, plate or rotary?<\/strong><br \/>Plate exchangers are simple, leak-tight, and good for moderate airflows. Rotary wheels suit larger volumes and can recover humidity, at the cost of slight stream carry-over.<\/p>\n<p><strong>Does recovery also improve comfort?<\/strong><br \/>Yes. By pre-conditioning ventilation air, it stabilizes indoor temperature and humidity and reduces the size of the heating and cooling plant needed.<\/p>","protected":false},"excerpt":{"rendered":"<p>Why Ventilation Wastes Energy Buildings need fresh air, but exhausting conditioned indoor air and bringing in untreated outdoor air can waste a large share of heating and cooling energy.
