Reverse Cycle Air Conditioners - Perth, Western Australia Commercial & Domestic Ducted Reverse Cycle Air Conditioners in Perth, WA

How do reverse cycle air conditioners work? Most electric heaters create heat directly, using elements which heat up when an electric current passes through them. These ‘direct element ’heaters include portable heaters, panel convectors and off-peak storage heaters. These air conditioning units have a maximum efficiency of 100%, when all the electricity is converted to heat and delivered to the room. Reverse cycle air conditioners extracts heat from the outside air, even on mid-winter nights, and transfers it inside. A refrigerant is passed through an external coil, absorbing heat from the outside air. This refrigerant is then pumped through a compressor into a fan coil unit (or ‘condenser ’) inside the roof space of the home, releasing its heat into the room. Up to three or more units of heat can be transferred for every unit of electricity used to run reverse cycle air conditioners. Therefore, running costs can be as low as one-third of those for direct element heaters. By reversing the flow of this refrigerant, reverse cycle air conditioners also provide efficient refrigerative cooling in summer.

One of the most economical forms of heating Able to provide both heating and cooling Remain cool to touch at all times Have no exposed elements or flames Lifetime of up to 20 years Filter and dehumidify air Ducted systems are designed to centrally heat and cool a large number of rooms or an entire home. They can be suitable if you have an open-plan house, and/or prefer heating and cooling in all or most rooms of your house simultaneously. As they heat and cool larger areas, they are more expensive to purchase and run than other types of air conditioners. Ducted systems consist of: the heat pump itself, located outside or in the roof space; ducting, is usually laid above the ceiling, distributing the conditioned air throughout the home; vents, attached to the ceiling or walls (or sometimes the floor), directing the conditioned air into each room; and a return air vent (grille) to reticulate air to the system for reheating. A filter is attached to the grille to reduce dust circulation. Wherever possible, it is recommended that ducted systems be zoned. Zoning divides a home into two or more sections that can be heated or cooled separately. This enables, for example, living areas to be conditioned during the day and sleeping areas at night, reducing running costs by up to 50%. Purchase costs are also reduced as a smaller system can be used. A single ducted unit can heat areas up to 200 m 2 . Contact us today for more info on our reverse cycle air conditioners. Will my power supply be efficient? It is recommended you contact Western Power to ensure you have sufficient power supply available to run any systems which are not connected to standard power points. Larger split and ducted systems, particularly with outputs greater than 11 kW, may require three phase power to be available. Sizing of air conditioning units... Click here fore more information on correct sizing of air conditioning units. Economical running costs rely on selecting reverse cycle air conditioning units that are the right size for your needs. Accurate sizing is essential before buying a unit and should include a detailed heat load survey of your home by qualified personal recommended by a unit ’s manufacturer or retailer. Under or oversized units will give poor performance. Ask for the reverse cycle air conditioners output capacity to be expressed in kilowatts (kW). Horsepower (HP) is often inaccurate and misleading as it measures the size of the motor, but does not accurately reflect the unit ’s output. Features to look for when buying air conditioning units... Programmable thermostats help in setting the most appropriate temperatures and to turn the system on and off at different times of the day. Generally, living areas should be kept at 18 –20 °C, with bedrooms between 16 –18 °C. If the unit has an external thermostat, it should be placed in a draught-free position in the main living area. It should not be placed near a return air grille and should be kept out of direct sunlight. ‘Economy ’cycles also help to save energy. These gradually decrease the output temperature of a unit for a few hours after it has been switched on. Correctly insulated ducting... Poorly insulated ducting will significantly decrease the performance of even the most efficient ducted air conditioning system, with significant heat losses and gains occurring through it. Ducting and all fittings should be insulated to a level of at least R0.6*, with all joints well-sealed and taped. Your ducting supplier will be able to provide ducting with the correct insulation level. *R values measure the ducting ’s resistance to heat loss and gain. The higher the value, the less heat will move through the ducting ’s outer surface. Vents... Ceiling vents should be located centrally in a room or between the centre and external walls. They should never be placed towards the internal walls, as air circulation will be impeded. ‘Four directional ’ceiling vents, or vents with adjustable louvers directed downwards rather than sideways, provide optimum heat distribution. Return air grille location... Locate the grille at floor level, or in the ceiling centrally positioned in the home. Ensure conditioned air flows directly through living areas before being recirculated. If you are installing a zoned system, we will ensure the grille is located correctly to enable the zoning to operate effectively. Maintenance... Maintain and service your reverse cycle air conditioners in accordance with manufacturer ’s instructions. Running costs - ducted air conditioning units...
Please note: The running costs on this page are based on Western Powers domestic tariffs (12.67 cents per kilowatt) correct at time of print. As tariffs will vary, check with Western Power for the tariff applicable to your home, and adjust running costs accordingly.
