Definitions

  • the second type of device used for this purpose is the fluid to fluid heat exchanger.
  • the heat exchanger typically uses steam or hot water from the central boiler system, used to heat the buil- ding, to heat hot water for public consumption. In the case of cooling, the heat exchanger would draw cold water from the cent ⁇ ral chiller circuit, used to cool the building, to cool the pot ⁇ able water.
  • This type of device typically requires too large a capital investment to be cost-effective in a residential situa- tion. It is used almost exclusively in commercial applications.

Abstract

Dans une série de plaques (5, 6) d'échangeurs de chaleur, chacune étant rectangulaire et pourvue dans ses coins d'orifices (7, 8, 9, 10), des plaques alternes (6) sont entièrement obturées et agissent de concert avec des plaques intermédiaires (5) pour définir deux groupes de passages allongés à travers lesquels les fluides respectifs (A, B) échangeant de la chaleur s'écoulent. Chaque plaque intermédiaire (5) n'est que partiellement obturée et définit avec l'une (6) des deux plaques adjacentes entièrement obturées un espace ouvert (20) communiquant directement avec l'atmosphère, l'obturation partielle consistant en des moyens d'obturation des orifices (7a, 8a, 9a, 10a) interconnectant les paires respectives d'orifices opposés pour former des canaux à travers lesquels les deux fluides (A, B) s'écoulent sans entrer dans ledit espace ouvert (20). Les espaces ouverts (20) forment des cheminements à travers lesquels toute fuite de l'un ou l'autre des fluides (A, B) peuvent s'échapper vers l'atmosphère, empêchant ainsi la contamination de l'un des fluides par l'autre.
