Confusing Air Con Terminology Explained
It’s summertime again and you’ve finally chosen the perfect air conditioner for your home. Sometimes when getting your new aircon installed, the specialists will be speaking in terms that you’ve never heard of before. This is why it’s important you need to know all the terms or lingo when it comes to air conditioning. First of all, some of the words are pretty straight forward and others aren’t always that simple. Some are abbreviated and others are explained in full length. Depending on the country, there are many words and meanings used as part of the Air Conditioning Glossary. For obvious reasons, we’ll be using Australian Terminology. Below are a few words we’ve found from the Glossary that we feel will be useful to you.
FROM A TO Z
ARC – Australian Refrigeration Council: A Council body that holds the responsibility of granting refrigeration handling licenses to approved Australian technicians. All Australian technicians must be licensed in order to install your air conditioner. If you’re unsure whether your local tradesman/air conditioner installer is licensed, don’t hesitate to ask. It’s better to be safe than sorry!
Absolute Pressure: Caused by gauge and atmospheric pressure. This can also be an equal amount of gauge pressure and atmospheric.
Air Diffuser: When air is distributed through a grill that is designed to divert and develop airflow. This airflow is then diverted to the designated area allowing the air to stay at a certain consistency.
Azeotropic Point: When a liquid mixture boils, it reaches a certain temperature where it produces a vapour through the same composition as the liquid.
Commissioning: Meaning a service that is conducted after the installation process to ensure all equipment is functioning correctly. The commissioning is an important part of the installation process as every aspect of the air conditioner must be in perfect working order.
Compressor: A key component in the air conditioner. It rises in pressure and in temperature allowing circulation through a loop system. This loop system also allows circulation throughout the designated area or house.
COP: Coefficient of performance (COP) is the value of the refrigerant effect (total capacity) versus the compressor over a unit of time. The higher the number, the more efficient the system.
CWR: Chilled water returns to a chiller or cooling system. The CWR stops the air conditioner from overheating and usually relies on a cooling tower method where chilled water is transferred over to the ventilation via piping. This piping is installed throughout the house allowing cool water to flow through the pipes leading all the way to the air conditioner where it is then dispersed into cool air.
CWS: Chilled water supply to a cooling unit. The water is usually supplied through the main water supply where it is stored for later use.
Dehumidification: In order to maintain humidity at the required level, the dehumidification process involves removing air that is contained in a conditioned space. The dehumidification eliminates the humidity in the house whilst also producing benefits such as improvement in health, better air circulation, provide a healthy home and reduce allergies.
Duct: Tubes that are mainly used for HVAC (Heating, Ventilation and Air Conditioning) that assist in the delivery and removal process of air.
DX: Direct Expansion Systems used to help expand or spread air around the contained room. This speeds up the cooling process, however, with a single split system, this can only work in one direct space instead of multiple spaces unless of course, you have a multi-split system.
EER: Energy Efficient Ratio. This ratio is used to determine the energy efficiency rating of each air conditioner or electrical appliance. The ratio is measured in different categories by star ratings (1-5) such as heating capacity, cooling capacity, watts per hour, cooling and heating efficiency, noise level and the three best climates across Australia and New Zealand. The more stars, the better the efficiency.
Free Cooling: This term implies free air that is cooled using three different types of systems such as water-cooled or glycol cooled. These systems can provide at least 80% more free cooling for the life of the air conditioner.
Gauge Pressure: A reading used to measure the atmospheric pressure. This is normally measured when the atmosphere is zeroed. It’s also equal to that of absolute pressure and is zero-referenced against ambient air pressure.
GWP: Global Warming Potential which measures global warming relative to CO2 =1. This figure is often between 5,000 and 10,000.
Heating/Cooling System: Based on the amount of capacity of heating/cooling the air conditioning unit can produce.
Heat Pump: Basically a reverse cycle air conditioner which can heat and cool indoor spaces.
HVAC: Short for heating, ventilation, and air conditioning. Some can be built to control humidity and regulate temperatures.
Hydronic System: A type heating and cooling system using ‘liquid heat transfer’ which allows heated water to travel through pipes situated under the floor.
Inverter Compressor: A type of compressor used as an inverter to drive the control through the motor speed.
Inverter Technology: An inverter that gradually increases/decreases power. This technology assists in achieving the desired room temperature.
Thermostat: A device specifically designed to control the temperature inside your home/space.
Refrigerant: A type of fluid used for the heat transfer process within a refrigeration system.
R410A: A non-ozone depleting refrigerant or fluid that transfers heat energy between the outdoor and indoor units.
R-32: Another refrigerant liquid that is more environmentally friendly as the R-32 has 66% lower global warming potential (GWP).
Vapour: A type of gaseous form that is released with the aircon unit hits a certain dew point which then formed into droplets of water.
Water-Cooled System: A type of refrigerant-based air conditioning system that uses water instead of gas. This refrigerant is safer than gas as it prevents hazardous explosions and can be damaging to your health.
Zerotrope: A refrigerant blend that consists of two or more components that are boiled at the same temperature.
Zoning: A method of heating or cooling used to change the temperature of different areas in one household.
