Air to Water Heat Pump<\/span><\/div>\n
\n
\n
A specific type of air source heat pump:<\/p>\n
It absorbs heat from the air \u2192 heats \/ cools water \u2192 uses water for heating, cooling, and domestic hot water supply.<\/span><\/div>\n<\/div>\n
<\/div>\n<\/div>\n
\n

Appearance & Working Principle<\/h2>\n<\/div>\n
\n
    \n
  • Outdoor unit: similar to an air conditioner outdoor unit, absorbs heat from the air<\/li>\n
  • Indoor side: connected to underfloor heating, radiators, fan coil units or hot water tanks<\/li>\n
  • Operation: electricity drives the compressor \u2192 extracts heat from the air \u2192 heats water \u2192 water delivers heat to rooms<\/li>\n<\/ul>\n<\/div>\n
    \n

    Principais caracter\u00edsticas<\/h2>\n<\/div>\n
    \n
      \n
    • Produces hot water, suitable for underfloor heating, radiators and domestic hot water<\/li>\n
    • High comfort: stable water temperature, no dry air, gentler than fan coil air conditioners<\/li>\n
    • Energy efficient: 1 kWh of electricity generates 3\u20135 times more heat energy<\/li>\n
    • Can be used for both cooling and heating: heating in winter, chilled water cooling in summer<\/li>\n
    • Ultra-low temperature models (EVI) operate normally for heating at -25\u00b0C to -35\u00b0C<\/li>\n<\/ul>\n<\/div>\n
      \n

      Difference from Air to Air Heat Pump<\/h2>\n<\/div>\n
      \n
        \n
      • Air to Air<\/strong>: air \u2192 air, direct cold\/hot air supply, i.e. standard air conditioners<\/li>\n
      • Air to Water<\/strong>: air \u2192 water, uses water for heating \/ cooling \/ hot water supply, commonly known as air source heat pumps or underfloor heating heat pumps<\/li>\n<\/ul>\n<\/div>\n
        \n

        Typical Applications<\/h2>\n<\/div>\n
        \n
          \n
        • Residential: triple supply \u2013 underfloor heating + central air conditioning + domestic hot water<\/li>\n
        • Commercial: hotel hot water, shopping mall water system air conditioning, swimming pool constant temperature heating<\/li>\n
        • Industrial: drying, constant temperature aquaculture, process hot water<\/li>\n<\/ul>\n<\/div>\n<\/div>","protected":false},"featured_media":0,"template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"default","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"categories":[],"faqcat":[397],"class_list":["post-7493","heatpump_faqs","type-heatpump_faqs","status-publish","hentry","faqcat-heat-pump-faqs"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.china-heatpump.com\/pt\/wp-json\/wp\/v2\/heatpump_faqs\/7493","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.china-heatpump.com\/pt\/wp-json\/wp\/v2\/heatpump_faqs"}],"about":[{"href":"https:\/\/www.china-heatpump.com\/pt\/wp-json\/wp\/v2\/types\/heatpump_faqs"}],"version-history":[{"count":1,"href":"https:\/\/www.china-heatpump.com\/pt\/wp-json\/wp\/v2\/heatpump_faqs\/7493\/revisions"}],"predecessor-version":[{"id":7494,"href":"https:\/\/www.china-heatpump.com\/pt\/wp-json\/wp\/v2\/heatpump_faqs\/7493\/revisions\/7494"}],"wp:attachment":[{"href":"https:\/\/www.china-heatpump.com\/pt\/wp-json\/wp\/v2\/media?parent=7493"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.china-heatpump.com\/pt\/wp-json\/wp\/v2\/categories?post=7493"},{"taxonomy":"faqcat","embeddable":true,"href":"https:\/\/www.china-heatpump.com\/pt\/wp-json\/wp\/v2\/faqcat?post=7493"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
