Hot or Cold: How Reverse Cycle Air Conditioner Works

A reverse cycle air conditioner refers to a heating-cooling system that reverses its refrigeration cycle. During winter season, reverse cycle air conditioners take heat from outside and transfer it inside the house. These units reverse their function during the summer – they take heat energy from inside the home and transfer it outdoors.

As with most commercial air conditioning systems, there are different types of reverse cycle air conditioner available on the market.

Split systems

A split-system air conditioner separates the system’s hot side from the cold side. The cold side is composed of an expansion valve and cold coil. It is usually placed into a blast furnace or air handler. The air handler helps by blowing air through the coil and then routing the air all over the building interior using a series of ducts. The hot side is the condensing unit is located on the outside of the building. The unit is made up of a long, spiral coil that looks like a cylinder. A fan blows air from inside the coil with the help of a weather-resistant compressor and software control logic.

Multi-head split systems

Multiple split or multi-head air conditioners have several wall split air conditioners powered by a single outdoor unit. This type of air conditioner provides flexibility as allows the control of individual room temperature and airflow.

Ducted systems

Ducted refrigerated air conditioning can cool and heat the inside of the building when needed as it filters the air and removes humidity. It combines the functionality of a ducted heating and a split system in each room but without the high cost.

A reverse cycle air conditioning system is designed to be more efficient than other electric heaters. In fact, most reverse cycle air conditioners can transfer three units of heat per electrical energy unit that they consume. With reverse cycle air conditioner, your home can become hot when it’s cold and, conversely, cold when it’s hot. Just like that Katy Perry song.
