Packaged Terminal Equipment
Factory-assembled packaged terminal air-conditioners and heat pumps intended for use in residential, commercial, and industrial heating and cooling systems.
A packaged terminal air-conditioner is a wall sleeve and a separate encased combination of heating and cooling assemblies specified by the manufacturer and intended for mounting through the wall. It includes refrigeration components, separable outdoor louvers, forced ventilation, and heating which may be provided by hot water, steam, or electrical resistance heat. Models designated as "cooling only" units need not include heating elements if the physical characteristics and arrangement of the refrigeration systems are identical to models with heating availability.
A packaged terminal heat pump is a separate encased refrigeration system installed in a cabinet of similar function and configuration to that of a packaged terminal air-conditioner. It utilizes reverse refrigeration as its prime heat source and should have another supplementary heat source which may be provided by hot water steam, or electric resistance heat.
Excluded are room air-conditioners, room fan-coil air-conditioners, water-source heat pumps, unitary single packaged air-conditioners and heat pumps, and single package vertical air conditioners and heat pumps.
Single Package Vertical Units
A single package vertical air conditioner consists of a separate encased or un-encased combination of cooling and optional heating components, factory assembled as a single package, and intended for exterior mounting on, adjacent interior to, or through, an outside wall. The major components of the unit are arranged vertically, and may contain separate indoor grille(s), outdoor louvers, various ventilation options, indoor free air discharge, ductwork, wall plenum or a sleeve. Heating components may include electrical resistance, steam, hot water, gas or no heat, but may not include reverse cycle refrigeration as a heating means. This equipment either alone or in combination with a heating plant, provides air-circulation, air-cleaning, cooling with controlled temperature and dehumidification, and may optionally include the function of heating and possible humidifying and ventilation.
