Title (EN) METHOD AND ARRANGEMENT FOR CONVEYING HEAT FROM EXHAUST AIR INTO INLET AIR BY A HEAT EXCHANGER VIA WHICH NON-FREEZING HEAT TRANSFER LIQUID IS CIRCULATED
(FR) PROCEDE ET DISPOSITIF D'ACHEMINEMENT DE LA CHALEUR CONTENUE DANS DE L'AIR DE SORTIE VERS DE L'AIR D'ADMISSION PAR UN ECHANGEUR THERMIQUE PAR L'INTERMEDIAIRE DUQUEL CIRCULE LE LIQUIDE DE TRANFERT THERMIQUE NON GELE
Abstract:
(EN) The invention relates to a method and arrangement for conveying heat, in which heating or cooling capacity is conveyed from the exhaust air (B-B') of ventilation or air conditioning of standard rooms into inlet air (A-A') by means of an inlet air heat exchanger, via which non-freezing heat transfer liquid is circulated. For reducing the investment costs, the non-freezing heat transfer liquid is brought into direct contact with the exhaust air (B-B').
(FR) L'invention se rapporte à un procédé et à un dispositif d'acheminement de la chaleur, la capacité calorifique ou refroidissante étant transférée de l'air de sortie (B-B') de ventilation ou de climatisation de locaux aux dimensions standards vers de l'air d'admission (A-A') au moyen d'un échangeur thermique par l'intermédiaire duquel circule le liquide de transfert thermique non gelé. Afin de réduire les coûts d'installation, le liquide de transfert thermique non gelé est directement mis en contact avec l'air de sortie (B- B').
