Abstract

Procédé de récupération de chaleur, basé sur l'utilisation d'une pompe de chaleur. Le système de pompe de chaleur comprend, en vue d'améliorer son coefficient thermique epsilon , une série de circuits de la pompe de chaleur séparés et fonctionnant en continu, dont les compresseurs (K1 ... Kn ) ont été pourvus d'un entraînement commun. Les condenseurs (L1 ... Ln ) des circuits des pompes de chaleur sont reliés en série par rapport à la masse qui s'écoule m à chauffer, de manière que la température t de la masse qui s'écoule m à chauffer s'élève quand elle est en contact d'échange de température avec le fluide qui circule dans les condenseurs (L1 ... Ln ) de la pompe de chaleur (p1 ... pn ). L'invention peut être utilisée notamment dans des installations de séchage de bois, de récupération de la chaleur d'eaux usées, etc.Heat recovery process, based on the use of a heat pump. The heat pump system comprises, in order to improve its thermal coefficient epsilon, a series of separate and continuously operating heat pump circuits, the compressors (K1 ... Kn) of which have been fitted with a drive common. The condensers (L1 ... Ln) of the heat pump circuits are connected in series with respect to the mass which flows m to be heated, so that the temperature t of the mass which flows m to be heated s' rises when it is in contact of temperature exchange with the fluid circulating in the condensers (L1 ... Ln) of the heat pump (p1 ... pn). The invention can be used in particular in installations for drying wood, recovering heat from wastewater, etc.
