By continuously rotating, the wheel transfers heat from one air stream to another; its working principle relies on the heat-storage and heat-release characteristics of the wheel material, rather than a fixed \"front\" or \"back\" direction.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, in actual installation and use, the \"air-inlet side\" and \"air-outlet side\" of a rotary heat exchanger may be defined artificially based on the system's airflow direction, piping layout, or design requirements. For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Heat-Recovery System<\/strong>the flow direction of cold and hot air determines which side is the \"input\" and which is the \"output.\"<\/li>\n\n\n\n<li><strong>Installation Environment<\/strong>the orientation of the equipment may be described as \"front\" or \"back\" due to space constraints or maintenance convenience.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">So, strictly speaking, a rotary heat exchanger has no inherent front\/back distinction, but in specific application scenarios it may be differentiated according to airflow or installation requirements.<\/p>","protected":false},"excerpt":{"rendered":"<p>\u8f6c\u8f6e\u6362\u70ed\u5668\uff08\u4e5f\u79f0\u4e3a\u70ed\u8f6e\u6216\u65cb\u8f6c\u5f0f\u6362\u70ed\u5668\uff09\u672c\u8eab\u5728\u8bbe\u8ba1\u4e0a\u901a\u5e38\u6ca1\u6709\u4e25\u683c\u7684\u201c\u524d\u540e\u201d\u4e4b\u5206\uff0c\u56e0\u4e3a\u5b83\u7684\u6838\u5fc3\u90e8\u4ef6\u2014\u2014\u8f6c [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[22],"class_list":["post-199","post","type-post","status-publish","format-standard","hentry","category-huanre","tag-22"],"_links":{"self":[{"href":"https:\/\/zhuanlun.169e.com\/en\/wp-json\/wp\/v2\/posts\/199","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=199"}],"version-history":[{"count":0,"href":"https:\/\/zhuanlun.169e.com\/en\/wp-json\/wp\/v2\/posts\/199\/revisions"}],"wp:attachment":[{"href":"https:\/\/zhuanlun.169e.com\/en\/wp-json\/wp\/v2\/media?parent=199"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/zhuanlun.169e.com\/en\/wp-json\/wp\/v2\/categories?post=199"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/zhuanlun.169e.com\/en\/wp-json\/wp\/v2\/tags?post=199"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
