In dry or cold climates an HRV is simpler and cheaper. A mixed climate uses an ERV with bypass for seasonal free cooling.<\/p>\n<p class=\"yc-faq\"><strong>Q: Does recovery hurt indoor air quality?<\/strong><br \/>No. Recovery exchanges energy, not bulk air; the specified outdoor-air rate is still delivered, so CO2 stays controlled while the heating and cooling energy is largely handed back.<\/p>\n<p class=\"yc-faq\"><strong>Q: What deployment tips matter?<\/strong><br \/>Size the unit to the actual occupancy and outdoor-air requirement, place filters for easy service, and use bypass or modulation so the ERV free-cools in mild weather instead of adding load.<\/p>\n<div class=\"yc-related\">\n<h3>\u95a2\u9023\u8a18\u4e8b<\/h3>\n<ul>\n<li><a href=\"https:\/\/www.26yc.com\/ja\/heat-recovery-payback-calculator\/\" title=\"\u71b1\u56de\u53ce\u306e\u6295\u8cc7\u56de\u53ce\u3092\u898b\u7a4d\u3082\u308b\uff1a\u8a08\u7b97\u6a5f\u3092\u7528\u3044\u305f\u5b9f\u8df5\u7684\u624b\u9806\">\u71b1\u56de\u53ce\u306e\u6295\u8cc7\u56de\u53ce\u3092\u898b\u7a4d\u3082\u308b\uff1a\u8a08\u7b97\u6a5f\u3092\u7528\u3044\u305f\u5b9f\u8df5\u7684\u624b\u9806<\/a><\/li>\n<li><a href=\"https:\/\/www.26yc.com\/ja\/plate-vs-heat-pipe-vs-rotary-heat-exchanger-which-one-to-specify\/\" title=\"\u30d7\u30ec\u30fc\u30c8 vs \u30d2\u30fc\u30c8\u30d1\u30a4\u30d7 vs \u56de\u8ee2\u5f0f\uff1a\u3069\u308c\u3092\u6307\u5b9a\u3059\u308b\u304b\">\u30d7\u30ec\u30fc\u30c8 vs \u30d2\u30fc\u30c8\u30d1\u30a4\u30d7 vs \u56de\u8ee2\u5f0f\uff1a\u3069\u308c\u3092\u6307\u5b9a\u3059\u308b\u304b<\/a><\/li>\n<\/ul>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Cramped classrooms with 30 students can blow past 1,000 ppm CO2 within an hour of occupancy if ventilation is weak, and ASHRAE 62.1 sets a minimum outdoor-air rate that, met with simple make-up air, dumps expensive conditioned energy straight out the window in winter.
