Portable Air Conditioners : The Basics

How does a portable AC work and cool the air?

Short version : ah! our favorite subject! Heat from air is absorbed by refrigerant. Find out more here!

A portable air conditioning unit extracts hot air from your room and exhausts it to the outside to ensure that your space has the desired temperature. Just like central air conditioners or any other type of air conditioners, this self-contained cooling system uses a refrigerant to cool the air in your room. This fluid flows in the system and changes state during the cooling process. The heat that is extracted from your room is exhausted to the outside through an exhaust hose. A single-hose cooling system has one hose while a dual system has two.

A portable air conditioning unit uses a fan to draw air into its cooling chamber. Most portable air conditioners have a filter that removes airborne particles from the incoming air. The incoming warm air is blown over the cooling coils. These coils contain a refrigerant that absorbs heat from the air making it cold. The heat absorbed from the warm air causes the refrigerant to evaporate. The cooled air is released back into your room.

From the cooling coils, the vaporized refrigerant goes to the compressor. The compressor compresses the refrigerant and pumps it to the condenser coils. Here, the refrigerant loses its heat to the air. This hot air is exhausted to the outside through the exhaust hose.

The refrigerant flows to the evaporator where it absorbs heat from incoming warm air for another cycle. This cycle is repeated over and over until the desired temperature is achieved. If you are using a single hose portable air conditioner, the cooling process creates a negative pressure inside the house.

As the air losses heat in the cooling coils, airborne moisture condenses on the coils. This water is channeled to a reservoir tank or an external sink. In high humidity environments, the system can capture a lot of water. When installed properly and serviced on regular basis, a portable air conditioner cools your room effectively to ensure that it has the desired environment.

Are portable air conditioners noisy?

Short version : no! Most portable AC’s emit noises under 65 dB. Check out our selection of silent portable ACs.

An air conditioner plays a critical role in ensuring that your home has a favorable environment. Whereas this appliance helps to effectively control the temperature of your bedroom, living room, or office, it can pollute the environment of your space by producing a disturbing sound.

As such, it is important to consider the noise rating of an air conditioner when selecting a unit for your space. If you are looking for a suitable air conditioner for a space that demands quietness, then it is advisable to go for a unit that runs quietly.

Overexposure to noise can put your health at risk, and it is, therefore, critical to select whisper quiet appliances. Research has shown that people who are overexposed to high levels of noise are more likely to experience loss of sleep, increased stress levels, hearing problems, blood pressure problems, and so on. As such, it is important to ensure that your unit does not expose your family to disturbing sounds.

The amount of noise produced by an air conditioner is measured in decibels, and the measuring device is known as a decibel meter. Most air conditioners produce 55 to 70 dB of noise. The amount of noise produced by an air conditioning unit mainly depends on the speed at which the unit is running, size of the appliance, and the make. Although all air conditioners produce sound, some are optimized to produce less noise. Such appliances are suitable for study rooms, living rooms, and other spaces that demand quietness.

Portable ACs are always less than 70 dB

Portable ACs are always less than 70 dB. Some are around 55dB.

Do portable air conditioners use freon?

Short version : they all use a refrigerant which should not leak.

A portable air conditioning unit uses a refrigerant to cool the air in your room and exhaust hot air to the outside. It changes states thereby allowing easy heat transfer. When warm air is drawn to the cooling chamber of a portable air conditioner, it passes over the coils of the evaporator. The low pressure Freon in the cooling pipes absorbs heat from the incoming warm air and evaporates. This causes the incoming air to cool. The cooler air is blown back to into the room.

Freon, courtesy of Honeywell

Freon, courtesy of Honeywell

From the evaporator coils, the vaporized Freon flows to the compressor where it is compressed. The compression process increases the temperature and pressure of the refrigerant. From the compressor, the high pressure liquid refrigerant flows to the condenser coils.

As air passes over the coils of the condenser, it absorbs heat from the liquid Freon. The warmer air is exhausted to the outside through the exhaust hose. From the condenser coils, the refrigerant flows to the evaporator, and the cycle is repeated again and again until the desired temperature is achieved.

Although Freon plays a critical role in eliminating excess heat from the air in your room, it is a dangerous gas when deeply inhaled. In gaseous state, Freon is odorless and tasteless, and it may not be easy to detect a minor leakage. Exposure to a low amount of Freon can cause dizziness, headaches, heart palpitations, and irritation of the eyes, lungs, or skin. When inhaled in high amounts, Freon can cut off the supply of oxygen to vital body organs.

As such, it is critical to ensure that your family is not exposed to a Freon leakage.

If you suspect that your appliance is releasing Freon, you should immediately remove it from your house to avoid exposing yourself and your family to high amounts of this toxic gas. You should then contact an expert to check the appliance and fix the problem.

→ Always make sure refrigerant is not leaking.

Do portable air conditioners drip water?

Short version : yes! It is collected in a tank that should be emptied from time to time.

Just like dehumidifier, a portable air conditioner captures some moisture from the air in your room. Airborne moisture condenses on the cooling coils as the refrigerant absorbs heat from incoming warm air. The cooling coils are usually freezing cold and this causes water vapor to condense on their surface. The amount of water captured by a portable air conditioner mainly depends on the amount of excess moisture in the air. In high humidity places, a portable air conditioner can capture a lot of water.

Emptying the tank is easy

Emptying the tank is easy

Most air conditioners have a reservoir for collecting the condensate. In low humidity environments, a portable air conditioner can run for many days without filling the tank. However, in high humidity environments, the unit can fill the tank in hours.

You can empty the water manually or you can drain the water to an external sink by gravity.

Most portable air conditioners have an indicator that alerts you when the reservoir is almost full. They are also designed to shut off automatically when the tank is full. This ensures that water does not spill on your carpet or floor.

In high humidity environments, the unit can be attention demanding, and this drainage method is, therefore, not a suitable option for such places. Draining the condensate under gravity enables your portable system to run for days without shutting off or demanding your attention.

It is important to note that the water captured by your air conditioner is not suitable for human or animal consumption. It contains a variety of harmful contaminants that can cause diseases. Air conditioners are not constructed with food grade materials, and the water captured by these units is likely to have compounds that can harm your body. You can use the condensate to water your lawns and flower garden, clean your car, and so on. It is advisable not to use the condensate for watering your fruits, vegetables, and other edible plants.
