It references key industry standards, specifically EN 1861 for refrigeration systems and heat pumps, and DIN 1946 for ventilation and air conditioning technology. The content serves as a quick-reference overview, categorizing common symbols for essential equipment, including various types of compressors (piston, scroll, jet), pumps (axial, centrifugal, piston), heat exchangers (finned tube, tubular, plate), and storage tanks. By establishing a uniform symbolic language, the document facilitates clear communication and accurate technical interpretation of complex cooling and climate control system designs. It is designed for engineers, technicians, and industry professionals who require a concise lookup guide for system diagrams, ensuring consistency across documentation and field applications.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":30,"@type":76,"position":81},"https://docshare.wps.com/document/technology/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/symbols-and-terms-refrigeration-and-air-conditioning-technology/664669/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/symbols-and-terms-refrigeration-and-air-conditioning-technology/664669.png","ImageObject",300,407,{"name":92,"@type":93},"SANS","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-30","2026-10-29",true,{"@type":102,"interactionType":103,"userInteractionCount":14},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What industry standards are used for these symbols?","Question",{"text":112,"@type":113},"The document cites EN 1861 for refrigeration systems and heat pumps, and DIN 1946 for ventilation and air conditioning technology.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"What are some examples of compressor types listed?",{"text":117,"@type":113},"The list includes general compressor symbols, piston compressors, scroll compressors, and jet compressors.",{"name":119,"@type":110,"acceptedAnswer":120},"Does the document provide an exhaustive list of all industry symbols?",{"text":121,"@type":113},"No, the document clarifies that this list provides only an extract of the available symbols used in the catalogue.","https://schema.org",{"og:url":83,"og:type":124,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":126,"canonical":83},"index,follow",{"doc_id":128,"site_id":62},664669,1793266559,{"code":4,"msg":5,"data":131},{"doc_id":128,"user_id":132,"nickname":92,"user_avatar":133,"doc_module":4,"category_id":29,"category_name":30,"doc_title":65,"doc_description":67,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":14,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":8,"language":139,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":67,"update_tm":129,"read_time":81},962090760505,"https://ap-avatar.wpscdn.com/davatar_155a257f0dc6eb9ab79c44ca47cae57d","Symbols and terms  \ngunt  \nSymbols and terms  \nIn refrigeration and air conditioning technology standardised symbols are used for process schematics.
