WHAT IS AIR CONDITIONING ?
Cooling Mode
Air conditioning is the precise control of temperature, humidity, air flow and air cleanliness. Air conditioners regulate these elements to provide you with the environment that can meet all your lifestyle requirements.
The refrigerant is the special liquid which flows through the indoor unit to absorb the excess heat indoors. It thens evaporates and is carried through narrow copper tubes to the outdoor unit as a gas, where the heat is released into the atmosphere. Thus , the gas becomes a liquid again and flows back to the indoor unit, where air is fanned over it and out into the room. This cycle is repeated until the preset temperature is reached.
Heating Mode
Heat pump air conditioning units additionally allow the cycle described above to be reversed. A heat pump extracts “free” heat from the outdoor air and transfers the heat indoors. This principle even continues to function on very cold days with temperatures down to -5°c, -10°c or -15°c, depending on the type of air conditioning system used. Therefore, heat pump units eliminate the need for a heating system and allow you to cool the heat with the same unit, with savings in costs and energy throughout the year.
What is Back-To-Back Installation?
This applies to the installation of a split system. If the installation is back to back the indoor unit is placed on the same wall as the outdoor unit reducing the amount of pipe run required to connect the two units.
What size unit will I need ?
There are a lot of factors taken into account when calculating the size of unit Eg. area size, glass etc. Finese recommends that you have a site visit by one of our sales experts to determine the correct size unit and type for your home or office. If site inspections are not possible then floor plans will aid in the preperation of your recommendation. Our sales representative will do a heat load calculation and also take into account the number of people occupying the area this is very important so you can save on cost and have an efficient running unit all year round.
What is the operating cost ?
The most energy efficient method of heating/cooling your home or office is reverse cycle air conditioning. Operating costs are determined by how long the air conditioning system runs.
It is important the correct size unit is installed . An undersized unit will be significantly more expensive to run taking longer to reach the temperature desired to heat/cool effectively.
Eg. The average 5hp ducted unit with a 5.7kw input would approximately cost 75cents per hour to operate.
What are the benefits of a ducted system over a split system?
A ducted system is designed to air condition more than one room within your home. The indoor fan coil unit is situated manually in the ceiling space and is connected to the outdoor condensing unit. Individual outlets are situated in each room with ceiling, wall or floor grilles so conditioned air can flow throughout which is controlled by a central controller. Unlike ducted the split system, is primarily designed to air condition only one room at a time. If you are looking to condition the whole house then you should consider a ducted system.
What is zoning in a ducted system?
Zoning allows you to turn on or off the air conditioning in certain areas of the house. This is done through the use of zone controls in the ductwork in the ceiling space.
eg. Two storey home may have 2 zones zone one for upstairs rooms and zone two for living areas downstairs. Other homes may have 3 to 5 homes depending on how they use there home.
