PTAC Air Conditioner
Using electricity as its power source, the PTAC compressor pumps refrigerant through the system. The refrigerant attracts heat and moisture from indoors and then transfers it outdoors. Heat and moisture inside are removed when warm air passes over the cool indoor coil. The heat and humidity in the air are removed by the coil, thereby "cooling" the air indoors.
When the PTAC operates in the heating mode air passes over heated electric resistance coils. If the unit is a heat pump which is more energy efficient, the AC refrigerant cycle operates in reverse. The refrigerant is used to create a heated indoor coil. As air passes over the heated coil the heat is transferred to the air inside the room creating warm air.
Indoor comfort all year - PTACs can rapidly remove heat and moisture from indoor air. You simply set the units thermostat to the temperature that you desire and the unit automatically cools to that level. You can manually select fan speed or use the automatic fan speed setting. When you need the room to be heated you use the same basic settings. Just set the thermostat to the temperature you want and select the heating function.
Simple Installation - PTACs are easy to install because they come in standard sizes and shapes. Regardless of the heating and cooling load requirements, the unit is the same size. Since both the heating and cooling systems exist inside a single unit, installation is easier than the installation of a split system.
Independent Operation - Unlike split-system heating and cooling systems which condition whole buildings through the use of ductwork, PTACs cool and heat only the rooms or spaces where they are installed. This means you cool or heat only what you want with individual temperature control. With multiple PTACs installed, you can easily control indoor temperature on a room to room basis.
