Types of Air Conditioning
The term “air conditioning” refers to any form of “Heating, ventilation and air-conditioning”, commonly referred to as HVAC. An air conditioner is a system or a machine that treats air in a defined, usually enclosed area, via a refrigeration cycle in which warm air is removed and replaced with cooler air that can in turn be humidified or dehumidified at the same time depending on the application it is designed for.
In colder climes they may be referred to as ‘Heat Pumps’. Nearly all air conditioners on the market today will heat and cool, referred to as ‘reverse cycle’. Cooling only models are normally reserved for specific rooms ie. data centres etc.
Human comfort level has been designated as 22.5°C and every person will have a personal comfort level either side of this temperature, which brings us to every technicians dilemma – keeping everyone comfortable at the same time.
From wine cellars to underground mines, air conditioning keeps workers reasonably comfortable so they can carry on their normal duties at work or play.
For this article we will deal with residential and commercial air conditioning.
Ducted Air Conditioning
As its name implies, a ducted system comprises a series of insulated ducts installed within a ceiling space (or under floor in some circumstances) which delivers conditioned air to the desired areas.
There are variations on this, but basically for a home air conditioning system one part, the fancoil, is installed within the ceiling cavity and the other half, the condensing unit, outside the house. They are interconnected by specially formed copper tubing (not plumbers copper) which delivers the circulating refrigerant between the two heat exchangers.
Ducted systems these days comprise a system with many zones, giving the user the option to close off rooms which are not in use. It is naturally a power saving mode. However, if your home has many zones, a common misconception here is that you can have all of them open at the one time if you wish and thus cool the whole house. I’m afraid you cannot. Your air conditioner is simply not big enough to condition the whole house at once – hence the zoning.

Wall Mounted Split Systems
These are the most common air conditioners on the market today. You will see them everywhere. They are economically priced so that nearly everyone has at least one of them in their house these days.
They comprise two main components – the wall mounted indoor unit and the outdoor condensing unit, connected by refrigeration copper for the circulating refrigerant.
The further apart the two items are from each other, the greater the installation cost.
A back to back installation is the cheapest option.

Multi Split Systems
A Multi split system is utilised in order to condition more than one room. They are basically connecting multiple indoor units to one outdoor unit. This is a space saving idea and more and more high rise apartments are using these due to space constraints. One drawback with these systems is that if the outdoor unit fails, then everything fails, as the outdoor unit is the heart of the system.

Cassette Type Air Conditioner
These types of air conditioner are more common in a commercial application and installed as close to the middle of the room as possible. They distribute air in four directions which makes them ideal for the application in which they are designed.
The illustration above shows the ceiling fascia which is all you will view of the indoor unit as they are installed through the ceiling with the main components out of sight.
As with most other types of air conditioners they also have their other half installed outside.

A Rooftop Package system can be extremely large and are usually reserved for commercial applications. You will often see them on top of shopping centres with large sheet metal ducting directing the conditioned air to the required locations.
They are one piece systems comprising all the necessary componentry neatly in one ‘package’.
They can be relatively time consuming for technicians to carry out repairs and service on due to their complexity and rooftop access.
