Thermally activated (engine-driven, absorption, etc.) ASHPs and ground-source heat pumps (GSHP)\u00a0was also included in individual country contributions if desired. The main technical objective was to identify solutions leading to ASHPs with heating SPF &gt; 2.63 W\/W, recognized as a renewable technology.<\/p>\n<p><strong>Start date:\u00a0<\/strong>July 2012<\/p>\n<p><strong>End date:\u00a0<\/strong>May 2017<\/p>\n<h3>Objectives<\/h3>\n<ul>\n<li>Identify potential equipment &amp; system options for detailed evaluation<\/li>\n<li>Determine energy savings potential over range of cold climate locations<\/li>\n<li>Develop final Annex report comparing various design options for cold climate heat pump applications on common basis<\/li>\n<\/ul>\n<p>The main outcome of this Annex was information-sharing on viable means to improve ASHP performance in cold climate locations \u2013 defined for purposes of the Annex as locales with a significant number of hours having ambient temperatures &lt; -7\u00b0C.<\/p>\n<h3>Project manager and participating countries<\/h3>\n<p>Austria, Canada, Japan, and the US (Operating Agent)\u00a0were participating in the Annex.<\/p>\n<h3>Publications<\/h3>\n<ul>\n<li><a href=\"https:\/\/heatpumpingtechnologies.org\/publications\/annex-41-two-page-summary-cold-climate-heat-pumps\/\" target=\"_blank\" rel=\"noopener\"><strong>HPT TCP Annex 41 Cold Climate Heat Pumps: Two-page\u00a0summary<\/strong><\/a><\/li>\n<li><a href=\"https:\/\/heatpumpingtechnologies.org\/publications\/cold-climate-heat-pumps-final-report\/\" target=\"_blank\" rel=\"noopener\"><strong>HPT TCP Annex 41 Cold Climate Heat Pumps: Final report<\/strong><\/a><\/li>\n<li><a href=\"https:\/\/heatpumpingtechnologies.org\/publications\/cold-climate-heat-pumps-executive-summary\/\" target=\"_blank\" rel=\"noopener\"><strong>HPT TCP Annex 41 Cold Climate Heat Pumps: Executive\u00a0summary<\/strong><\/a><\/li>\n<\/ul>\n<h2><a href=\"http:\/\/web.ornl.gov\/sci\/usnt\/QiQmAnnex\/indexAnnex41.shtml\">The website of Annex 41 can be viewed here<\/a><\/h2>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>The primary focus was on electrically driven air-to-air or air-to-water air-source heat pumps (ASHP), with air or hydronic heating systems,&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"_relevanssi_hide_post":"","_relevanssi_hide_content":"","_relevanssi_pin_for_all":"","_relevanssi_pin_keywords":"","_relevanssi_unpin_keywords":"","_relevanssi_related_keywords":"","_relevanssi_related_include_ids":"","_relevanssi_related_exclude_ids":"","_relevanssi_related_no_append":"","_relevanssi_related_not_related":"","_relevanssi_related_posts":"","_relevanssi_noindex_reason":"","footnotes":""},"class_list":["post-106","page","type-page","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/heatpumpingtechnologies.org\/annex41\/wp-json\/wp\/v2\/pages\/106","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/heatpumpingtechnologies.org\/annex41\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/heatpumpingtechnologies.org\/annex41\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/heatpumpingtechnologies.org\/annex41\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/heatpumpingtechnologies.org\/annex41\/wp-json\/wp\/v2\/comments?post=106"}],"version-history":[{"count":7,"href":"https:\/\/heatpumpingtechnologies.org\/annex41\/wp-json\/wp\/v2\/pages\/106\/revisions"}],"predecessor-version":[{"id":206,"href":"https:\/\/heatpumpingtechnologies.org\/annex41\/wp-json\/wp\/v2\/pages\/106\/revisions\/206"}],"wp:attachment":[{"href":"https:\/\/heatpumpingtechnologies.org\/annex41\/wp-json\/wp\/v2\/media?parent=106"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
