L\u2019\u00e9volution de la r\u00e9glementation demande la transition vers les fluides avec un impact faible sur l\u2019environnement voire nul, c\u2019est \u00e0 dire, sans effet sur la couche d\u2019ozone, ni de cons\u00e9quence sur l\u2019effet de serre. Pour fonctionner, les machines con\u00e7ues pour \u00eatre utilis\u00e9es avec les fluides actuels doivent \u00eatre adapt\u00e9es, tant au niveau du syst\u00e8me qu\u2019au niveau des composants (condenseur, \u00e9vaporateur...). L\u2019objet de ce travail de DRT est de d\u00e9velopper des connaissances sur les \u00e9changeurs d\u2019une pompe \u00e0 chaleur utilisant des hydrocarbures comme fluides frigorig\u00e8nes.<\/p>\n<p>C\u2019est dans ce contexte que le GREThE a d\u00e9cid\u00e9, avec le soutien de l\u2019ADEME, de lancer une \u00e9tude sur l\u2019utilisation des hydrocarbures dans les pompes \u00e0 chaleur. Un des avantages d\u2019utiliser le propane pur est d\u2019affranchir les industriels de l\u2019utilisation des nouveaux m\u00e9langes et des inconv\u00e9nients inh\u00e9rents \u00e0 leur utilisation. De plus, une \u00e9tude ant\u00e9rieure (Tiffon S. [2003]) sur la boucle P\u00e9p\u00e9 a montr\u00e9 la viabilit\u00e9 d\u2019un tel projet. En effet, des essais ont permis de mettre en \u00e9vidence que le COP (Coefficient de Performance) obtenu avec le propane (R290) sur un cycle thermodynamique est comparable \u00e0 celui que l\u2019on obtiendrait avec du R22. C\u2019est dans cet esprit que l\u2019on aborde des essais en propane, afin de caract\u00e9riser thermodynamiquement la machine avec une configuration d\u2019\u00e9changeurs diff\u00e9rente.<\/p>\n<table width=\"100%\" border=\"1\">\n<tr>\n<td><strong>Auteur(s)<\/strong><\/td>\n<\/tr>\n<tr>\n<td>VACHER S\u00e9bastien<\/td>\n<\/tr>\n<tr>\n<td><strong>Ann\u00e9e<\/strong><\/td>\n<\/tr>\n<tr>\n<td>2006<\/td>\n<\/tr>\n<tr>\n<td><strong>Mots-cl\u00e9s<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Pompe \u00e0 chaleur, propane, performance, \u00e9changeur<\/td>\n<\/tr>\n<\/table>\n\n&nbsp;<br \/>\n\n<div class=\"eds-animate edsanimate-sis-hidden \" data-eds-entry-animation=\"bounceIn\" data-eds-entry-delay=\"0\" data-eds-entry-duration=\"1\" data-eds-entry-timing=\"linear\" data-eds-exit-animation=\"\" data-eds-exit-delay=\"\" data-eds-exit-duration=\"\" data-eds-exit-timing=\"\" data-eds-repeat-count=\"1\" data-eds-keep=\"yes\" data-eds-animate-on=\"load\" data-eds-scroll-offset=\"\">\n\t\t<div class=\"box info  \">\n\t\t\t<div class=\"box-inner-block\">\n\t\t\t\t<span class=\"fa tie-shortcode-boxicon\"><\/span>\n<p style=\"text-align: justify;\"><strong>&#x2666; The full version is only available for subscribers <a style=\"text-decoration: none;\" href=\"\/offre-du-greth\/\"><span style=\"background-color: #3db2ea; color: #fff;\">\"ESSENTIEL\"<\/span><\/a> or <a style=\"text-decoration: none;\" href=\"\/offre-du-greth\/\"><span style=\"background-color: #c6002c; color: #fff;\">\"PREMIUM\"<\/span><\/a> of GRETh!<\/strong><\/p>\n<p>&#x2666; If you are already a member \/ subscriber, you must identify yourself by <a href=\"\/wp-login.php\"><strong>clicking here<\/strong><\/a>.<br \/>\n&#x2666; If you are not a member, you can consult the offer proposed by GRETh by <a href=\"\/offre-du-greth\/\"><strong>clicking here<\/strong><\/a> as well as the conditions of membership by <a href=\"\/conditions-adhesion\/\"><strong>clicking here<\/strong><\/a>.\n\t\t\t<\/div>\n\t\t<\/div>\n\t<\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>R\u00e9sum\u00e9 : Les machines de r\u00e9frig\u00e9ration et de climatisation actuelles fonctionnent avec des fluides HFC.
