05 f\u00e9vrier 2007 - Douze pompes \u00e0 chaleur air-air \u00e0 vitesse variable ont \u00e9t\u00e9 \u00e9valu\u00e9es par des mesures en laboratoire et les r\u00e9sultats ont \u00e9t\u00e9 compar\u00e9s \u00e0 des \u00e9tudes similaires r\u00e9alis\u00e9es en 2001 (contr\u00f4le de la capacit\u00e9 \u00e0 vitesse variable) et en 1991 (compresseurs \u00e0 vitesse unique). Les pompes \u00e0 chaleur ont \u00e9t\u00e9 \u00e9valu\u00e9es en termes d'efficacit\u00e9, de performance du syst\u00e8me de d\u00e9givrage et de capacit\u00e9 \u00e0 fonctionner dans un climat froid.<\/b><\/p>\n

Les r\u00e9sultats montrent que les pompes \u00e0 chaleur sont devenues plus efficaces depuis 1991 et 2001. En moyenne, le coefficient de performance (COP) a augment\u00e9 de 7-24 % depuis 1991. Les syst\u00e8mes de d\u00e9givrage se sont \u00e9galement am\u00e9lior\u00e9s, bien qu'il existe encore des syst\u00e8mes qui, dans la pratique, fonctionnent avec une simple commande temporelle et effectuent donc inutilement de nombreux cycles de d\u00e9givrage, ce qui r\u00e9duit les performances et probablement aussi la dur\u00e9e de vie de l'\u00e9quipement.<\/p>\n
