Abstract:
A method of installing a single package air conditioner unit in a walled structure comprising the steps of:(a) positioning the unit against an outside wall;(b) forming an opening through the outside wall;(c) forming an air flow path through the wall opening through an elongated telescoping plenum enabling air flow to transfer heat between the air outside the walled structure and inside the walled structure so that said single package air conditioner unit transfers heat;(d) forming a return air flow path communicating with said unit inside the walled structure;(e) directing treated air from the unit to flow in the walled structure and ultimately return to said return air flow;(f) positioning said unit in a cabinet defining at least part of the return air path;(g) wherein said cabinet is tailored to a particular return air path dependent on the walled structure;(h) said telescoping plenum is elongated to extend to the outer face on the wall; andsaid plenum is mounted to an opening defined louver at the distal end thereof and said plenum is positioned in a sealing relationship to aid single package air conditioner unit; and forming two flow paths along said plenum wherein one flow path is from inside the walled structure and the second flow path is from outside to inside the walled structure.
