How does a Heat Pump Work?
Heat Pumps are sealed systems similar to a refrigerator - but unlike your fridge they can both heat and cool. Here's how:
Feel the warm air that rises from the back of your fridge. Believe it or not, that warmth is coming from inside. An evaporator coil extracts warmth from the air inside, and transfers it out into your kitchen through a condenser coil on the back.
Heat pumps work much the same way. Two linked coils, one inside your home, one outside, circulate a refrigerant that draws warmth from the outside air and transfers it into your home. There are three different system options available depending on your requirements and building type.
These units take many forms and are designed to be discreet both in appearance and in operation. An outdoor unit contains the heat pump compressor, which is the business end of the system. The indoor unit can be mounted at floor level (console), in the ceiling (cassette), or at high level on the wall (hi-wall). This simple indoor unit circulates the warm or cold air as required, providing a quiet and highly efficient system for a single room/area.
With this option, several indoor units can be connected to a single outdoor unit. This allows you to select the ideal type and capacity of unit best suited to each individual room in your home. The multi-system enhances exterior aesthetics by reducing the number of outdoor units necessary and provides you with an easy and economical option to add indoor units at any time.
Generally designed to heat and cool an entire home, a ducted system includes an indoor unit mounted within the roof space (or sometimes under the floor) with flexible duct work distributing conditioned air through small vents located throughout the home. Many consider this the ideal heat pump air conditioning solution - it is efficient, it requires only one outdoor unit, and the use of small grilles makes it unobtrusive. Ducted systems can be designed to operate in two or more zones which can be heated or cooled at different times.
