Add On Cooling
Refrigerated add-on cooling is added on to a ducted heating system (in ceiling or under floor), providing both air conditioning and gas heating through the same outlets and ducts. Add on cooling is typically zoned giving you the options of what areas you would like to cool in your home, eg., living (during the day) and/or bedrooms (at night). One of the best advantages with zoning would be that it is cost effective.
Providing you have the correct size ducted heating system, add on cooling can be installed at a later stage.
How it works?
Air from inside your home is drawn and filtered via the return air grille. The air then passes through an indoor coil where the heat in the air is transferred to the refrigerant. The now cold air passes through the ductwork and into the rooms via the ceiling or floor vents. The heat given up by the air in the indoor coil is carried by the refrigerant to an outdoor coil where it is dissipated to the outside air.
Evaporative Cooling
An evaporative cooling system is some what the most inexpensive way to cool your entire home. It is also one of the healthiest ways to cool your home, using clean fresh air that replaces the existing air in your home.
How it works?
Evaporative cooling comprises of a central cooling unit connected to a series of outlets installed in your ceiling throughout your house. The cooling unit is installed on top of your roof. The unit draws in fresh air from outside your house, through moistened pads. As the air passes through the pads it is filtered before flowing through the ductwork into your rooms. The air flow given is compared to a comfortable sea breeze. Unlike refrigerated cooling which requires you to keep windows and doors closed to maintain a cooler temperature, evaporative cooling requires you to leave doors and windows open. This is great news if you have children who constantly run in and out of the house.
