Title
(EN) HVAC SYSTEM
(FR) SYSTÈME DE CVC
Abstract
(EN) An HVAC system for a multi-unit building having a riser stack in flow communication with a single unit HVAC system. The single unit HVAC system has a first heat exchanger thermally connected to the riser stack, a second heat exchanger thermally connected to a fluid distribution system within the unit, and a closed loop fluid flow path extending between the first and second heat exchangers. The first heat exchanger exchanges heat between a riser stack fluid in the riser stack and the closed loop fluid in the closed loop fluid flow path and the second heat exchanger exchanges heat between the closed loop fluid and a distribution fluid of the fluid distribution system.
(FR) Système de CVC pour un bâtiment à unités multiples présentant un empilement de colonnes montantes en communication fluidique avec un système de CVC à unité unique. Le système de CVC à unité unique comprend un premier échangeur de chaleur thermiquement relié à l'empilement de colonnes montantes, un second échangeur de chaleur thermiquement relié à un système de distribution de fluide à l'intérieur de l'unité, et un trajet d'écoulement de fluide à boucle fermée s'étendant entre les premier et second échangeurs de chaleur. Le premier échangeur de chaleur échange de la chaleur entre un fluide d'empilement de colonnes montantes dans l'empilement de colonnes montantes et le fluide à boucle fermée dans le trajet d'écoulement de fluide à boucle fermée, et le second échangeur de chaleur échange de la chaleur entre le fluide à boucle fermée et un fluide de distribution du système de distribution de fluide.
