Title (EN) USING HEAT RECOVERED FROM HEAT SOURCE TO OBTAIN HIGH TEMPERATURE HOT WATER
(FR) UTILISATION DE LA CHALEUR RÉCUPÉRÉE D'UNE SOURCE DE CHALEUR POUR OBTENIR DE L'EAU CHAUDE À HAUTE TEMPÉRATURE
Abstract:
(EN) Heat is recovered from a heat source to heat water to high temperatures. Apparatuses, systems and methods are described to heat water to a high temperature by using heat, such as may be considered in some instances as waste heat, recovered from a heat source. The methods, systems, and apparatuses described utilize low pressure refrigerant(s) as a fluid to provide a refrigeration cycle that utilizes a source of heat to heat water to a high temperature. The refrigeration cycle can be with or without a cascade cycle. The refrigerant cycle in some examples uses an oil free compressor.
(FR) L'invention a pour but de récupérer de la chaleur à partir d'une source de chaleur afin de chauffer de l'eau à des températures élevées. À cet effet, l'invention concerne des appareils, des systèmes et des procédés destinés à chauffer de l'eau à une température élevée au moyen de l'utilisation de la chaleur, comme celle qui peut être considérée dans certains cas comme chaleur perdue, récupérée à partir d'une source de chaleur. Les procédés, les systèmes et les appareils décrits utilisent au moins un fluide frigorigène à basse pression en tant que fluide pour fournir un cycle frigorifique utilisant une source de chaleur afin de chauffer l'eau à une température élevée. Le cycle frigorifique peut être avec ou sans cycle en cascade. Selon certains exemples, le cycle frigorifique utilise un compresseur sans huile.
