Air conditioning, often abbreviated as a/c or ac, is the process of removing heat from an enclosed space to achieve a more comfortable interior environment (sometimes referred to as 'comfort cooling') and in some cases also strictly controlling the humidity of internal
air
. Air conditioning can be achieved using a mechanical 'air conditioner' or alternatively a variety of other methods, including passive cooling and ventilative cooling.
Air conditioning is a member of a family of systems and techniques that provide heating, ventilation, and air conditioning (hvac). Heat pumps are similar in many ways to air conditioners, but use a reversing valve to allow then to both heat and also cool an enclosed space.
This unit of study develops an advanced knowledge of air conditioning systems and refrigeration applications. At the completion of this unit students will be able to determine thermal loads on structures and design an air conditioning or refrigeration system with attention to comfort, control, air distribution and energy consumption. Course content will include: applied psychrometrics, air conditioning systems, design principles, comfort in the built environment, cooling load calculations, heat ing load calculations, introduction and use of computer-based load estimation packages software, air distribution, fans, ducts, air conditioning controls, advanced refrigeration cycles, evaporators, condensers, cooling towers, compressors, pumps, throttling devices, piping, refrigerants, control, refrigeration equipment, simulation of refrigeration systems, food refrigeration and industrial applications; use of cfd packages as tools to simulate flows in building and to optimise air conditioning design, energy estimation methods and software, energy evaluation and management in the built environment.
Air conditioning is the process of removing heat/cold and moisture from the interior of an occupied space and often means equipment used for that process. A common air conditioner uses a mechanical system called a “heat pump” that allows for the transfer of heat between indoor and outdoor units, with the help of a gaseous refrigerant. An air conditioner draws heat from the indoor exchanger and releases it to the outdoor exchanger. When cooling, the compressor inside the outdoor unit liquefies the refrigerant to absorb heat. When heating, conversely, heated pressurized gas generated by the heat exchanger and compressor inside the outdoor unit is condensed to heat air in the room.

The most common type in australian homes is split system air conditioning units. This means there are two components, one placed outdoors and the other indoors. These frequently feature reverse cycle functionality, offering cool air conditioning in summer and heating in winter. Window/wall air conditioners are compact and easy to install, making them ideal for smaller spaces. An inverter air conditioner provides faster cooling while maintaining an optimum room temperature. We also stock a selection of portable air conditioners that can be transported from room to room to provide cooling wherever needed. For the tech-forward home, shop our smart air conditioners that allow you to monitor temperature and humidity levels remotely using your smart phone.
The fan speed that you use does in-fact impact on the overall heating or cooling performance of your air conditioning unit. Ford & doonan recommend operating the air conditioner on a high speed fan setting. This delivers the system’s maximum capacity. At night, selecting a lower fan speed setting or turning less zones on can also be beneficial. On modern air conditioning controllers, that can be simply done via the app.
Hvac systems account for an estimated 39% of the energy currently used in commercial buildings in the united states. Therefore, most business or government agency have the potential to realize significant savings by improving their control of hvac operations and improving the efficiency of the system they use. There are basically two approaches to conditioning a room or building. The first method is using a radiant system, the second is using a forced air system. Radiant systems usually involve running hot or chw through pipes that loop around the structure and radiate into the conditioned space via a floor surface or radiator pipe.
