Air Conditioning Glossary (5)

  • Split System – A system where the compressor box is situated outside the building and the head unit circling the air is mounted on the wall inside the room. Split system air conditioning provides convenience during hot summer months (and cold winter days), and is effective when cooling (or heating) a single room or a large area.
  • Reverse Cycle – Reverse cycle air conditioners provide comfort all year round, with the ability to offer cooling in summer and heating in winter. They are perfect for regulating the temperature of a large area and use a refrigerant gas to transfer heat to and from your home.
  • Inverter – Inverter technology uses a variable speed compressor motor similar to a car, with the main function being to slow down and speed up as needed to hold a selected comfort setting. This technology provides a more precise room temperature without the temp variations of fixed speed systems.
  • Ducted – A large cooling fan sits outside and pumps cool air around the building through ducts in the ceiling cavity. Ducted air conditioning gives you complete control for every room in your home – it offers finger-tip control with a single, simple command point for zones, temperature and timers. And with even air distribution, there are no hot or cold spots.  
  • Evaporative – Evaporative air cooling uses evaporation to cool the air through a fan. The system’s fan and motor are sized and designed to deliver the appropriate airflow for the home.
  • Condenser – A condenser unit is a type of heat exchanger, varying in size from small, household appliance units to large, industrial size units and consists of a compressor, a condenser, a fan motor, controls and a mounting plate. Condensing units can be used as cooling in refrigerators and air conditioners.
  • Kilowatt (kW) – This is a unit of energy; the kilowatt rating measures the output of the air conditioner, with ratings given for both cooling and heating. All residential air conditioners carry a label showing the unit’s cooling output in kilowatts.
  • Energy Rating – These labels provide a comparative assessment of the appliance’s energy efficiency and typical annual energy consumption (in kilowatt hours per year). This information will help you understand the energy requirements and running costs of the air conditioning unit. Before purchasing an air conditioning unit, you should check the energy rating label. 
  • Thermostat – This device controls the temperature by turning on or off the air conditioning unit. The thermostat is set at a certain temperature and when the house cools (or heats) to that temperature, the unit will turn off.

  1. Learning as much as I can about AC systems is important to choosing the right one. We will be getting a new one soon but we don’t know which kind yet. Luckily summer is not coming fast, unlike when you wrote this article I think, so we can take our time and do plenty of research.
