The desiccant is then regenerated, ideally with recovered heat, and circulated in a closed loop. Because the cooling coil now deals only with sensible load at a higher evaporating temperature, the chiller or DX plant runs fewer compressors and reaches a better COP. Controls must coordinate three loops, supply temperature, supply humidity, and desiccant concentration, so a modest building-management sequence is needed. Retrofit cases usually keep the existing coils and add the membrane module and desiccant circuit, which limits capital outlay. The approach suits humid-climate offices and labs most, where latent load dominates; in dry climates the added complexity rarely pays back versus plain sensible recovery.<\/p>\n<h2>\u5e38\u89c1\u95ee\u9898<\/h2>\n<p><strong>How does a membrane air-conditioning system raise chiller COP?<\/strong><br \/>By removing latent load with a desiccant loop at a higher coil evaporating temperature, which reduces compressor lift.<\/p>\n<p><strong>What are the main components?<\/strong><br \/>A membrane contactor, a liquid-desiccant regenerator, a sensible recovery core, and the standard AHU fans, filters, and coils.<\/p>\n<p><strong>Is membrane AC a replacement for energy recovery?<\/strong><br \/>No. It is best viewed as an extension of total-energy recovery that handles the latent load a basic core does not.<\/p>\n<p><strong>Where does membrane AC pay back best?<\/strong><br \/>In humid-climate offices and laboratories with large latent loads; dry climates see marginal benefit versus plain sensible recovery.<\/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\/industrial-drying-heat-recovery\/\" title=\"\u5de5\u4e1a\u5e72\u71e5\u4e0e\u519c\u4e1a\u7684\u70ed\u56de\u6536\">\u5de5\u4e1a\u5e72\u71e5\u4e0e\u519c\u4e1a\u7684\u70ed\u56de\u6536<\/a><\/li>\n<\/ul>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Membrane air conditioning systems separate the sensible and latent cooling loads using a liquid-desiccant loop and a membrane contactor, rather than a single overcooling coil.
