Abstract

L'invention concerne un refroidisseur à pompe à chaleur (10) comportant un carter (11) qui renferme des compresseurs, etc., et quatre échangeurs de chaleur à plaque (22, 22, 24, 24) disposés sur le côté du carter (11) et s'étendant verticalement. Deux échangeurs de chaleur (22, 24) forment un premier corps d'échangeur de chaleur (21) et un second corps d'échangeur de chaleur (23). Chaque corps d'échangeur de chaleur (21, 23) est disposé de sorte que les extrémités (22b, 24b) des échangeurs de chaleur à air (22, 22, 24, 24), dans la direction dans laquelle ils s'étendent vers l'extérieur, sont à proximité les unes des autres.
