Actual savings scale with airflow and the winter temperature lift.<\/p>\n<p class=\"yc-faq\"><strong>Q: Will a rotary wheel mix exhaust air back into the supply?<\/strong><br \/>A properly specified wheel includes a purge sector that scavenges residual exhaust from the matrix before it reaches the supply sector, keeping cross-leakage very small. Where any mixing is unacceptable, a plate or run-around coil provides complete stream separation.<\/p>\n<p class=\"yc-faq\"><strong>Q: Where does the recovered data center heat usually go?<\/strong><br \/>Common sinks are reheat for VAV terminal boxes in adjacent office space, preheat of outdoor air for the building HVAC, and domestic water pre-heat on larger campuses. Pairing recovery with the site existing sizing logic keeps the integration straightforward.<\/p>\n<p class=\"yc-faq\"><strong>Q: Is a rotary wheel or a run-around coil better for a tight plant room?<\/strong><br \/>A rotary wheel is the most compact option and also recovers humidity, which helps in humid climates. A run-around coil is preferred when ducts are far apart or when the design forbids any chance of exhaust-to-supply mixing.<\/p>\n<div class=\"yc-related\">\n<h3>Art\u00edculos relacionados<\/h3>\n<ul>\n<li><a href=\"https:\/\/www.26yc.com\/es\/rotary-wheel-frost-defrost\/\" title=\"Frost and Defrost Strategies for Rotary Energy Wheels in Cold Climates\">Frost and Defrost Strategies for Rotary Energy Wheels in Cold Climates<\/a><\/li>\n<li><a href=\"https:\/\/www.26yc.com\/es\/heat-recovery-food-agriculture-drying-en\/\" title=\"Waste Heat Recovery in Food and Agriculture Drying: Why Plate Exchangers Win\">Waste Heat Recovery in Food and Agriculture Drying: Why Plate Exchangers Win<\/a><\/li>\n<\/ul>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Server rooms reject enormous, constant heat.
