Take The Cover Off The Unit, & Locate The Air Conditioner Coils
This system is called a “split” system because it is made up of two units: one indoor and one outdoor. The former houses the evaporator and cooling fan. The latter, meanwhile, houses the compressor, expansion valve, and condenser.
Split air conditioning systems provide the added convenience of not having to make a specialised slot in the room wall. Also, modern split air conditioners do not take as much space as window units.
This type is also referred to as a “packaged terminal air conditioner.” These are usually used in motels, hotels, and apartments. This is a variation of the unitary air conditioning system.
This type has a mobile air conditioning system placed on the floor inside a room. It discharges exhaust heat through the exterior wall by means of a hose vent.
While this type is noisier than other systems, it can cool even the most stubborn hot rooms. This type is best for large buildings, hotels, movie theatres, factories, and other bigger spaces.
Fitting individual units like window air conditioners in each room of a big building can get super expensive. Having a central air conditioning system is the more practical choice when it comes to applications like this.
This type of system makes use of a large compressor. Two separate packaged units are also used. The condensing unit is placed outside the establishment and contains the condensing fan, compressor, and condenser coil.
