Abstract

Milieux d'échange de chaleur stabilisés. Ces milieux comprennent un hydrocarbure fluoré, un absorbant, et un stabilisant formé de phosphite; les absorbants préférés sont des dérivés de furane asymetriques, contenant au moins un oxygène avec une liaison simple avec un atome de carbone adjacent, de préférence, c'est un éther d'alkyltétrahydrofurfuryle ; l'hydrocarbure fluoré contient 1 à 2 atomes de carbone, 1 ou 2 hydrogènes et le restant étant formé de chlore et de fluor; les phosphites ont la formule (R',O) (R'2 0) (R'3 O)P où R' 1 et R'2 et R'3 représentent chacun indépendamment un groupe alkyle, alkényle, phényle, alkylènephenyle, alkylènealkylphenyle ou alkylphényle. La présente invention est particulièrement utile pour fournir des milieux stabilisés d'échange de chaleur pour des pompes à chaleur par absorption.
