The Difference Between Reverse Cycle And Split System Air Conditioners

Air conditioners help keep us comfortable in our homes, offices, and cars. No matter what the weather is like outside, it comforts us according to our needs.

With their ability to regulate temperature and humidity, air conditioners play a crucial role in providing relief from extreme weather conditions year-round.

And today we will learn about the difference between reverse cycle and split system air conditioners. These two air conditioners are the most popular and front-runners in Australia

Reverse-Cycle Air Conditioner

This special air conditioner does two jobs in one. It can both cool and warm up your place. So, no matter the season, your home will stay cozy. It’s perfect at doing its job efficiently compared to other systems.

When it’s hot, it takes the heat from inside your home and sends it outside to cool things down. But when it’s chilly, it reverses the process, bringing heat from outside into your home.

That means, even when it’s freezing outside, there’s still some heat out there to bring in. You can find reverse cycle air conditioners in two types: ducted and split systems.

How Does A Reverse-Cycle Air Conditioner Function?

Reverse cycle air conditioning functions by reversing the normal operation of an air conditioning system to provide both heating and cooling. Here’s how it works:

Absorbing Heat:

In cooling mode, the system works like a regular air conditioner. It absorbs heat from inside your home using a refrigerant. This refrigerant absorbs the heat and evaporates into a gas.

Reversing the Cycle:

When you switch to heating mode, the system reverses the flow of the refrigerant. Instead of absorbing heat from the inside, it extracts heat from the outside air, even in cold temperatures. This heat exchange process is possible because there is still some heat energy present in the outdoor air, even when it’s cold.

Heat Distribution:

The absorbed heat from outside is then transferred indoors using the same refrigerant cycle. The heat is released inside your home through the indoor unit’s coils, warming up the indoor air.

Air Circulation:

The indoor fan then circulates the warmed air throughout your home, providing comfortable heating during colder weather.


Reverse cycle air conditioning is often more energy-efficient than other heating methods because it doesn’t generate heat but rather transfers it from one place to another. This can result in cost savings on energy bills. By reversing the refrigerant flow, reverse-cycle air conditioning systems provide both cooling and heating capabilities, making them versatile and suitable for year-round use.

Split-System Air Conditioner

A split air conditioner is a type of air conditioning system that consists of two main units: an indoor unit and an outdoor unit.

The indoor unit is usually mounted on a wall inside the room or area to be cooled, while the outdoor unit is typically placed outside the building. These units are connected by refrigerant lines and electrical wiring.

The indoor unit contains the cooling coil, fan, and air filter, while the outdoor unit houses the compressor, condenser coil, and fan.

The indoor unit absorbs heat from the room air and transfers it to the outdoor unit, where it is released into the outside air. This process cools the indoor air.

Split air conditioners are popular because they are efficient, and quiet, and can be used to cool individual rooms or multiple rooms by installing multiple indoor units connected to a single outdoor unit.

They are commonly used in residential, commercial, and institutional buildings for cooling purposes.

How Does a Split-System Air Conditioner Work?

A split system air conditioner works by using a process called refrigeration to cool down the air inside your home. Here’s how it works:

Indoor Unit:

This unit is installed inside your home, typically on a wall. It contains the evaporator coil, which is responsible for absorbing heat from the indoor air. A fan inside the indoor unit blows air over the evaporator coil, cooling it down.

Outdoor Unit:

The outdoor unit is usually located outside the building. It contains the compressor, condenser coil, and a fan. The compressor pressurizes the refrigerant gas, causing it to become hot. As the hot gas travels through the condenser coil, it releases heat into the outdoor air, causing the gas to condense into a liquid.

Refrigerant Circulation:

The cooled liquid refrigerant then travels through copper tubing to the indoor unit. Inside the indoor unit, the expansion valve reduces the pressure of the liquid refrigerant, causing it to evaporate into a gas once again. This process absorbs heat from the indoor air, cooling it down.

Air Circulation:

The indoor fan blows air over the cooled evaporator coil, and this cooled air is then circulated throughout your home via ducts or simply by the unit’s positioning.

Cycle Continues:

The refrigerant continues to cycle between the indoor and outdoor units, absorbing heat from inside and releasing it outside, thus cooling down the indoor air. By repeating this cycle, a split system air conditioner can effectively cool down the air inside your home, keeping you comfortable even on hot days. Some split systems also have a reverse cycle feature, allowing them to provide heating as well as cooling by reversing the direction of refrigerant flow.
