Abstract
A packaged terminal air conditioner (PTAC) system includes a wall sleeve in which a chassis is mounted. The chassis includes the major electrical and mechanical components for the evaporator and condenser sections, and includes a pan that collects condensate from the evaporator section for use in cooling the condenser coil. The sleeve includes one or more guide openings in a sidewall, and correspondingly mounted guide structures inside the sleeve that are configured to guide treatment pellets into different portions of the PTAC system to suppress or inhibit microbial growth. This arrangement obviates the need to partially disassemble the PTAC unit to remove the chassis so that treatment pellets can be placed into the PTAC unit.
