The wrong choice routinely adds USD 25,000 to USD 80,000 of unnecessary equipment cost \u2014 or quietly wastes 20 to 30 percent of the energy savings you thought you were getting.

class=\"yc-faq-title\">\u5e38\u89c1\u95ee\u9898<\/h2>\n<p class=\"yc-faq\"><strong>Q: What is the difference between sensible and total energy recovery?<\/strong><br \/>Sensible recovery transfers temperature only, using a plate or heat-pipe bank. Total recovery also transfers moisture, using an enthalpy wheel, desiccant wheel or membrane core, which matters when humidity dominates the load.<\/p>\n<p class=\"yc-faq\"><strong>Q: When is sensible-only recovery the right answer?<\/strong><br \/>Choose sensible-only when the exhaust is dry, the climate is mild, cross-contamination rules out rotating equipment, or capital cost is the binding constraint. Offices, schools and datacom halls are typical fits.<\/p>\n<p class=\"yc-faq\"><strong>Q: When does total latent recovery pay off?<\/strong><br \/>In humid, cooling-dominated climates an enthalpy wheel moves both heat and moisture, cutting the cooling and reheat load that a sensible device would miss. The latent saving often justifies the higher first cost.<\/p>\n<p class=\"yc-faq\"><strong>Q: Can a wrong choice add cost without benefit?<\/strong><br \/>Yes. Specifying total recovery where the space is dry wastes the desiccant premium and can over-humidify, while specifying sensible-only in a humid climate quietly forfeits 20 to 30 percent of the available saving.<\/p>","protected":false},"excerpt":{"rendered":"<p>A practical guide to choosing between sensible-only and total-energy recovery for commercial AHUs, with capital cost ranges and break-even analysis.<\/p>","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[72,70],"tags":[186,182,174,188,185,190,221],"class_list":["post-4571","post","type-post","status-publish","format-standard","hentry","category-heat-recovery","category-industrial","tag-ahu","tag-energy-recovery","tag-heat-exchanger","tag-latent","tag-procurement","tag-rotary-wheel","tag-sensible-recovery"],"_links":{"self":[{"href":"https:\/\/www.26yc.com\/zh_cn\/wp-json\/wp\/v2\/posts\/4571","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.26yc.com\/zh_cn\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.26yc.com\/zh_cn\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.26yc.com\/zh_cn\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.26yc.com\/zh_cn\/wp-json\/wp\/v2\/comments?post=4571"}],"version-history":[{"count":3,"href":"https:\/\/www.26yc.com\/zh_cn\/wp-json\/wp\/v2\/posts\/4571\/revisions"}],"predecessor-version":[{"id":5212,"href":"https:\/\/www.26yc.com\/zh_cn\/wp-json\/wp\/v2\/posts\/4571\/revisions\/5212"}],"wp:attachment":[{"href":"https:\/\/www.26yc.com\/zh_cn\/wp-json\/wp\/v2\/media?parent=4571"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.26yc.com\/zh_cn\/wp-json\/wp\/v2\/categories?post=4571"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.26yc.com\/zh_cn\/wp-json\/wp\/v2\/tags?post=4571"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
