Glossary of Air Conditioning Terms

 

Vocab that lets you speak like an authority on all things air conditioning 

Here at Mercury Installations our air conditioning service and installation technicians make a point to speak in clear and easy to understand language wherever possible, however this doesn’t mean that there isn’t some terminology that leaves some people scratching their heads. For this reason we’ve put together a list of common in industry lingo in our air conditioning glossary below.

Air Filter – Responsible for catching particles in the air flow.

Coil – The part of an air conditioning system that transfers or collects heat depending on the flow of air.

Compressor – The component that is responsible for squeezing the refrigerant gas which in turn increases the temperature of the refrigerant.

Ductwork – The silver coloured tubing or pipe shaped material installed in the ceiling where air flows in ducted air conditioning systems.

EER – Stands for Energy Efficiency Rating – A measure used to determine the energy efficiency of an AC system.

Evaporator – Responsible for dehumidifying air by converting a liquid refrigerant into gas form. Used to remove the heated air inside the room.

Grille – A panel (usually steel) with linear slits that covers the opening to a ceiling or wall used in ducted systems.

Heat Pump – The component which pumps air either in a inward or outward direction depending if the system is heating or cooling.

HVAC – Stands for heating, ventilation, air conditioning

Humidifier – A product that adds humidity to indoor air during winter or in hot dry climates. – Not needed in Queensland.

Louvre – The movable slats used in split system air conditioners which control the angle of air fow

Refrigerant – R22 refrigerant is also known as Freon. A refrigerant is a chemical that can provide a cooling effect by expanding or vaporising.

Reversing valve – A device which reversed the movement of refrigerant in the system depending on whether it is set for cooling or heating.

Thermostat – The essential component that allows you to set the room to a desired temperature. It self regulates the air temperature to maintain the temperature at the level that has been set.

Zoning – Used in ducted systems to create separate areas in a home or commercial building to save energy. In larger buildings zoning lets you cool different areas as needed.

Understanding how some of the major components of an AC system work goes a long way in understanding the technology in an air conditioning system. Here at Mercury Installations our technicians will be happy to explain air conditioning related and provide advice on the best system for your home. Call our office today on (07) 3312 4244.
