For moisture recovery, confirm whether the standard\u2019s total-effectiveness test applies to the unit you are buying.<\/p>\n<h2>Selecting a Compliant Unit<\/h2>\n<p>Match the device type to the air streams: separated plate cores for dirty or contaminated exhaust, wheels where moisture recovery is wanted and carryover is acceptable. <a href=\"https:\/\/www.26yc.com\/zh_cn\/contact-us\/\">\u8054\u7cfb\u6211\u4eec<\/a> for a GB\/T 21087-aligned recommendation, or email kuns913@gmail.com \/ WhatsApp +86 15753355505.<\/p>\n<p class=\"yc-faq-title\"><strong>\u5e38\u89c1\u95ee\u9898<\/strong><\/p>\n<div class=\"yc-faq\">\n<h3>What does GB\/T 21087 cover?<\/h3>\n<p>China\u2019s GB\/T 21087 specifies requirements and test methods for air-to-air energy recovery devices including plate, rotary, heat-pipe and run-around coil types.<\/p>\n<\/div>\n<div class=\"yc-faq\">\n<h3>Why does GB\/T 21087 matter for buyers?<\/h3>\n<p>It is the baseline compliance mark for devices sold in China and a useful specification reference for global buyers sourcing from Chinese manufacturers.<\/p>\n<\/div>\n<p><strong>Effectiveness grades and export notes<\/strong><br \/>GB\/T 21087 classifies devices by recovery type and rates sensible (and, for enthalpy units, total) effectiveness against defined test conditions. For export equipment, treat GB\/T 21087 as the Chinese baseline and pair it with the target market mark CE\/EN 308 for Europe or AHRI 1060 for North America so the same core can be documented for both.
