Four of the most common types of air conditioners

1Written by Movincool

Based on the requirements of the space in question, you will have different options when it comes to air conditioning systems. This choice depends on a few factors, such as space, expected heat generation within the space etc indoor or outdoor cooling etc. Here are the most common types of air conditioners:

Window air conditioner

This is the most common and one of the oldest types of air conditioners used today. With this type of air conditioner, the compressor, condenser, expansion valve or coil, evaporator and cooling coil and any other units are all in a single unit. It gets its name from the most common mounting location which is on a window sill.

Split air conditioner

Unlike the single unit window air conditioners, a split a/c has an indoor and an outdoor unit. These two are connected through ducting for the air to be sent and returned from the outdoor unit which contains the compressor, condenser and expansion valve. The indoor unit on the other hand contains the evaporator or cooling coil and the cooling fan.

Package air conditioner

These units are required if you want to cool more than one or two rooms or larger areas. In this situation the cooled air is sent through various ducts that cool different sections of the rooms. This is a common design for a server room air conditioner where the cooling is sent out through raised floor vents.


The final and most expensive type is the central air conditioner. This is the system that cools hotels, malls, factories and large offices. This is when it becomes too costly to run individual or multiple packaged units to cool several areas. The larger the space the more economical it is to run central air conditioners.
