Calculation method of air leakage rate<br>The air leakage rate of the rotary heat exchanger can be calculated by the following formula:<br>Air leakage rate = (1-\u03b5)100%<br>in:<br>\u03b5: heat transfer efficiency<br>2. Factors affecting air leakage rate<br>The air leakage rate of the rotary heat exchanger is affected by the following factors:<br>Clearance between the rotor and the seal<br>Seal material<br>Seal aging degree<br>Rotor speed<br>Filter clogging degree<br>Temperature difference<br>3. The harm of air leakage rate<br>The air leakage rate of the rotary heat exchanger will reduce the heat exchange efficiency, increase energy consumption and affect the indoor air quality.<br>4. Measures to reduce air leakage rate<br>Reduce the wheel speed<br>Regular inspection and maintenance of seals<br>Clean the filter<br>Reduce temperature difference<br>5. Typical air leakage rate<br>The air leakage rate of the rotary heat exchanger is generally between 5% and 15%, but it may be higher.<\/p>","protected":false},"excerpt":{"rendered":"<p>\u8f6c\u8f6e\u6362\u70ed\u5668\u7684\u6f0f\u98ce\u7387\u8f6c\u8f6e\u6362\u70ed\u5668\u7684\u6f0f\u98ce\u7387\u662f\u6307\u5728\u8f6c\u8f6e\u6362\u70ed\u5668\u8fd0\u884c\u8fc7\u7a0b\u4e2d\uff0c\u7531\u4e8e\u5bc6\u5c01\u4e0d\u4e25\uff0c\u5bfc\u81f4\u65b0\u9c9c\u7a7a\u6c14\u548c\u6392\u6c14\u7a7a\u6c14 [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[21],"class_list":["post-171","post","type-post","status-publish","format-standard","hentry","category-chushi","tag-rotary-heat-exchangers"],"_links":{"self":[{"href":"https:\/\/zhuanlun.169e.com\/en\/wp-json\/wp\/v2\/posts\/171","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zhuanlun.169e.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/zhuanlun.169e.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/zhuanlun.169e.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/zhuanlun.169e.com\/en\/wp-json\/wp\/v2\/comments?post=171"}],"version-history":[{"count":1,"href":"https:\/\/zhuanlun.169e.com\/en\/wp-json\/wp\/v2\/posts\/171\/revisions"}],"predecessor-version":[{"id":172,"href":"https:\/\/zhuanlun.169e.com\/en\/wp-json\/wp\/v2\/posts\/171\/revisions\/172"}],"wp:attachment":[{"href":"https:\/\/zhuanlun.169e.com\/en\/wp-json\/wp\/v2\/media?parent=171"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/zhuanlun.169e.com\/en\/wp-json\/wp\/v2\/categories?post=171"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/zhuanlun.169e.com\/en\/wp-json\/wp\/v2\/tags?post=171"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
