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>\u76f8\u5173\u6587\u7ae0<\/h3>\n<ul>\n<li><a href=\"https:\/\/www.26yc.com\/zh_cn\/rotary-wheel-frost-defrost\/\" title=\"\u5bd2\u51b7\u6c14\u5019\u4e0b\u65cb\u8f6c\u5f0f\u80fd\u91cf\u56de\u6536\u8f6c\u8f6e\u7684\u7ed3\u971c\u4e0e\u9664\u971c\u7b56\u7565\">\u5bd2\u51b7\u6c14\u5019\u4e0b\u65cb\u8f6c\u5f0f\u80fd\u91cf\u56de\u6536\u8f6c\u8f6e\u7684\u7ed3\u971c\u4e0e\u9664\u971c\u7b56\u7565<\/a><\/li>\n<li><a href=\"https:\/\/www.26yc.com\/zh_cn\/heat-recovery-food-agriculture-drying-en\/\" title=\"\u98df\u54c1\u4e0e\u519c\u4e1a\u5e72\u71e5\u4e2d\u7684\u5e9f\u70ed\u56de\u6536\uff1a\u4e3a\u4f55\u677f\u5f0f\u6362\u70ed\u5668\u80dc\u51fa\">\u98df\u54c1\u4e0e\u519c\u4e1a\u5e72\u71e5\u4e2d\u7684\u5e9f\u70ed\u56de\u6536\uff1a\u4e3a\u4f55\u677f\u5f0f\u6362\u70ed\u5668\u80dc\u51fa<\/a><\/li>\n<\/ul>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Server rooms reject enormous, constant heat.
