Air Conditioning Technical Terms Clarified
Inverter and Non-Inverter Systems
The difference between Inverter and non Inverter systems is Inverter systems continuously and constantly maintain a set temperature and can alter their speed in response to cooling demand, unlike conventional non-inverter systems which operate on a ‘stop and start’ principle. Inverter systems work like the cruise control of a car, gently increasing or decreasing power according to the temperature setting. The benefits are constant comfort, significant energy savings and very quiet operation.
Reverse Cycle
Reverse-cycle Air Conditioning is designed to both cool and heat your home. This is achieved by having the refrigeration gases run in reverse direction, hence the name.
Cooling Only
These units, as the name suggests can only cool. Although they are less expensive than reverse cycle units to run, they cannot be used in winter to heat your home.
Horse Power versus Kilowatt
Horse power is a very basic sizing of air conditioning output. Construction and mechanical engineering consultants use kilowatts as a more accurate means of measuring required capacity.
Split Systems
Split systems are designed for specialist operation in your home or office, able to cool or heat more than one room and consists of connected components. The working unit fits on an outside wall which helps to keep the noise out of the house whilst the output device is mounted on an inside wall, on the ceiling or it could even be floor standing.
Ducted Systems
In a Ducted Air Conditioning system, an outdoor unit (condenser) is connected to an indoor unit (fan coil) which supplies warm or cool conditioned air to concealed flexible ductwork that runs through the ceilings of the property. The air is then disbursed into each room via outlets in the walls, floor or ceiling.
The outdoor unit may be mounted on brackets or a concrete slab while the indoor unit is usually placed in your roof space or under the floor. A wall-mounted indoor temperature controller allows you to operate and control all functions of the system.
