Do Reverse Cycle Air Conditioners Draw Air From Outside

Australia has one of the best climates the world has ever seen, with long summers and comparatively mild winters. Air Conditioning has been working to improve the air quality inside our homes and create a comfortable environment for us to strive in no matter what the weather may be.

What Is a Reverse Cycle Air Conditioning Unit?

Reverse Cycle Air Conditioners that are also known as heat pumps are units that offer both cooling and heating to provide the ultimate climate control throughout the year. This is done by reversing the refrigeration cycle so that the system can cool in summer and heat in winter. The Reverse Cycle System is extremely efficient adaptable and flexible.

How Does It Work?

Reverse Cycle Air Conditioner filters and removes moisture from the surrounding air to heat your home in winter and cool your home in summer. Basically, the Reverse Cycle Ducted Air Conditioning Unit works by the simple rules of heat absorption and the refrigeration cycle.

How Does a Reverse Cycle Unit heat?

In winter, the system extracts heat from the outside and brings it inside the home. You might be thinking what if heat is nowhere to be found outside? Well, the answer to that question is that a good Reverse Cycle Air Conditioning Unit with an automatic defrost cycle can effectively heat your home even if the outside temperature drops to as low as -15℃.

When set to heating, the refrigerant gas is passed through an external coil to absorb the heat from the outside air. This is then pumped down into the condenser by a compressor. On being compressed, the refrigerant warms up. This hot air is then pumped out into the room through a fan. Once this is done, the refrigerant flows through another evaporator to cool it down before being pumped back into the condenser to repeat the cycle.

How Does a Reverse Cycle Unit cool?

Just by pressing a button, the Reverse Cycle Air Conditioning Unit can start working in cooling mode. When this mode is enabled, the entire process discussed above is reversed. The Reverse Cycle Air Conditioning Unit will now start absorbing heat from the air inside your home and throw it outside, leaving your home cooler in return. A good Reverse Cycle Air Conditioning unit can cool down your home even in temperatures as high as 46℃.

Do Air Conditioners Take In Air From Outside?

In simple words, no, the air conditioners do not take in air from the outside into your home. Even though in split air conditioner designs, heat pumps are located outside your home, they do not bring outside air inside your home. The main operational purpose of the air conditioning unit, cooling, is achieved by moving the undesired heat from the home to the outside, not by moving the cool air inside.

The heat from the inside is kicked out through the heat pump which works both ways. It can either move the heat outside in summer and inside in the winter with the help of refrigerant fluid.

Does a Window Air Conditioner Pull Air From Outside?

You might be thinking that the window air conditioners pull in air from the outside as they go through the wall to the outside of your home. However, that’s not the case. Window Air Conditioners do not bring in the outside air. In fact, they only recirculate the air that is already present inside your home while cooling and filtering it during the process.

Is There Any Air Conditioner That Uses Outside Air?

No, the air conditioners are not designed to bring in fresh air from the outside. They either cool or heat your homes by moving the heat outside or inside respectively with the help of the refrigerant fluid. Evaporative coolers on the other hand work on this principle. They pass the outdoor air over the pads that are saturated with water. The water in the pads evaporates, reducing the air temperature before it is directed inside the home.
