Reviewing the various features helps consumers make an informed decision when purchasing a home cooling system.
Trane uses the term Packaged Terminal Air Conditioner, or PTAC, to describe these units, which are installed through an exterior wall. Some high-end models will heat the room during the winter in addition to cooling the room during the summer.
These units are popular in hotels because it simplifies individual temperature control in each room. Turning the unit off when the room is unoccupied saves money and energy.
A PTAC capable of heating a room is a heat pump, which reverses the cooling process and delivers warm air to the room.
Trane’s PTACs have between 7,000 and 15,000 BTUs and utilize either 265 or 208 volt electricity for power. Some have up to 5 kilowatts, while others are not designed for electrical heating.
Users have the option of controlling the unit with a remote. This feature is convenient for hotel operators who can operate units from a central location to ensure the air conditioners are not wasting energy in unoccupied rooms.
These units are compatible with different types of thermostats. Maintenance workers can easily set the thermostats at the desired upper and lower temperatures. In some cases, an additional temperature sensor is installed in a more desirable location inside the room.
Units are also capable of dehumidifying the air only, without providing cooling power. A filter purifies the outside air to remove dust and allergens, creating a healthier environment. Most units are quiet with the fan on the low setting.
A unit with a heat pump will automatically turn on when power is restored after an outage. Each unit can be set to restart at a different interval to eliminate the risk of a power surge caused by multiple units turning on at the same time.
Many consumers prefer a central heating and air conditioning system because it is quiet and efficient but through the wall coolers have their own distinct advantages and are worthy of consideration.
