A packaged terminal air conditioner, also known as PTAC units, is a type of self-contained heating and air conditioning system commonly found in hotels and apartment buildings. These systems are designed to go through a wall, having vents and heat sinks both inside and outside. Typically these systems will come in standard sizes.
PTAC units are designed as a heating (and cooling) system ideal for single living spaces. The PTAC units are designed to use only electricity, which make them ideal for commercial offices or hotels. The heating capacity will typically range from 2 to 5.5 kilowatts nominal. The PTAC units have several unique characteristics which make them ideal for operations which have many small rooms. The condensate drain piping which is found on pretty much all heating units is not required because the condensate water extracted from the air by the evaporator coil is drawn by the condenser fan onto the condenser coil surface where it evaporates. This eliminates the need for unattractive or expensive drainage systems connected to PTAC units. However, conventional PTACs that utilize older technology may still require the drain piping.
Sizing a PTAC unit can be done quickly and easily with sizing charts provided by manufacturers. A room of 150 square feet will utilize a 5,000 BTU sized unit and a 1600 square foot room will need a 32,000 BTU unit. The typical rule of thumb is that you need about 25 BTUs for every square foot of area. However, it is always good to contact the manufacturer or a technician and get an energy audit to determine the specifics.
