HVAC system with modular architecture
HVAC system includes a front side access panel, an HVAC unit, a mounting sleeve, and a back side grille. The mounting sleeve and the HVAC unit are configured to fit within the preexisting framing of a building, and in particular to be mounted in a wall, between pre-existing studs, of a room. The HVAC unit can be installed into the mounting sleeve via quick connect mechanisms including, but not limited to, snap in connections and/or tab and slot features. The mounting sleeve enables rapid installation and also condensate collection. The HVAC unit includes separate modular units, e.g. an evaporator module unit, a mechanical module unit, and a condenser module unit, that are mounted and interconnected to each other. The HVAC system includes vertically oriented HVAC components and component connections that are self-aligned, and can be further configured with a horizontal configuration portion for multi-zone capability.
