The diagram illustrates the relationship between absolute pressure in bar and specific enthalpy in kJ/kg, serving as an essential tool for evaluating refrigeration cycles and heat pump performance. Developed and produced by TecQuipment using their specialized VDAS® (Versatile Data Acquisition System) technology, the resource provides high-precision data visualization suitable for engineering academic environments. It enables students and researchers to accurately map state points, calculate enthalpy changes, and understand phase transitions within vapor-compression systems. The document serves as an authoritative visual guide for experimental cooling processes, facilitating the study of heat transfer, energy balance, and compressor efficiency through structured graphical data representation.",{"@graph":14,"@context":66},[15,34,49],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/template/","Template",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/template/posters/","Posters",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/template/pressure-enthalpy-diagram-r-134a-produced-by-tecquipment/563625/",4,{"url":32,"name":10,"@type":35,"author":36,"headline":10,"publisher":39,"fileFormat":42,"inLanguage":8,"description":12,"dateModified":43,"datePublished":43,"encodingFormat":42,"isAccessibleForFree":44,"interactionStatistic":45},"DigitalDocument",{"name":37,"@type":38},"Jake","Person",{"url":19,"name":40,"@type":41},"DocShare","Organization","application/pdf","2026-10-12",true,{"@type":46,"interactionType":47,"userInteractionCount":4},"InteractionCounter",{"@type":48},"ViewAction",{"@type":50,"mainEntity":51},"FAQPage",[52,58,62],{"name":53,"@type":54,"acceptedAnswer":55},"What is the substance represented in the diagram?","Question",{"text":56,"@type":57},"The diagram represents R-134a, also known as 1,1,1,2-tetrafluoroethane, a common refrigerant.","Answer",{"name":59,"@type":54,"acceptedAnswer":60},"What units are used for the axes on this diagram?",{"text":61,"@type":57},"The vertical axis represents Pressure measured in Bar, and the horizontal axis represents Enthalpy measured in kJ/kg.",{"name":63,"@type":54,"acceptedAnswer":64},"What system was used to produce this diagram?",{"text":65,"@type":57},"This diagram was produced using TecQuipment’s VDAS® (Versatile Data Acquisition System) system.","https://schema.org",{"og:url":32,"og:type":68,"og:title":10,"og:site_name":40,"og:description":12},"article",{"robots":70,"canonical":32},"index,follow",{"doc_id":72,"site_id":7},563625,1791836888,{"code":4,"msg":75,"data":76},"success",[77,82,87,92,96,101,106,111,116],{"id":78,"doc_module":22,"doc_module_name":25,"category_name":79,"show_sort_weight":80,"slug":81},11,"Presentations",90,"presentations",{"id":83,"doc_module":22,"doc_module_name":25,"category_name":84,"show_sort_weight":85,"slug":86},12,"Resumes",80,"resumes",{"id":88,"doc_module":22,"doc_module_name":25,"category_name":89,"show_sort_weight":90,"slug":91},14,"Invoices",70,"invoices",{"id":93,"doc_module":22,"doc_module_name":25,"category_name":29,"show_sort_weight":94,"slug":95},15,60,"posters",{"id":97,"doc_module":22,"doc_module_name":25,"category_name":98,"show_sort_weight":99,"slug":100},16,"Social Media",50,"social-media",{"id":102,"doc_module":22,"doc_module_name":25,"category_name":103,"show_sort_weight":104,"slug":105},17,"Forms",40,"forms",{"id":107,"doc_module":22,"doc_module_name":25,"category_name":108,"show_sort_weight":109,"slug":110},18,"Letters",30,"letters",{"id":112,"doc_module":22,"doc_module_name":25,"category_name":113,"show_sort_weight":114,"slug":115},21,"Paper Templates",5,"papers-templates",{"id":117,"doc_module":22,"doc_module_name":25,"category_name":118,"show_sort_weight":4,"slug":119},158,"General","general-158",{"code":4,"msg":75,"data":121},{"doc_id":72,"user_id":122,"nickname":37,"user_avatar":123,"doc_module":22,"category_id":93,"category_name":29,"doc_title":10,"doc_description":12,"doc_content":124,"file_id":125,"file_url":126,"file_type":127,"file_size":128,"view_count":4,"is_deleted":4,"is_public":22,"is_downloadable":22,"audit_status":22,"page_count":22,"language":129,"language_code":8,"site_id":7,"html_lang":8,"table_of_contents":130,"faqs":131,"seo_title":132,"seo_description":12,"update_tm":73,"read_time":4},962084928904,"https://ap-avatar.wpscdn.com/davatar_155a257f0dc6eb9ab79c44ca47cae57d","Pressure-Enthalpy Diagram R-134 a (1,1,1,2-tetrafluoroethane)  \nProduced by TecQuipment’s VDAS® system  \nPressure (Bar)  \nEnthalpy (kJ/Kg)  \n[tecquipment. com](tecquipment. com)","cbCairF42ct1YbYr","https://ap.wps.com/l/cbCairF42ct1YbYr","pdf",362323,"English","# Pressure-Enthalpy Diagram R-134a\n## Thermodynamic Parameters\n## VDAS System Documentation","[{\"question\":\"What is the substance represented in the diagram?\",\"answer\":\"The diagram represents R-134a, also known as 1,1,1,2-tetrafluoroethane, a common refrigerant.\"},{\"question\":\"What units are used for the axes on this diagram?\",\"answer\":\"The vertical axis represents Pressure measured in Bar, and the horizontal axis represents Enthalpy measured in kJ/kg.\"},{\"question\":\"What system was used to produce this diagram?\",\"answer\":\"This diagram was produced using TecQuipment’s VDAS® (Versatile Data Acquisition System) system.\"}]","Pressure-Enthalpy Diagram R-134a -
