Ventless Portable Air Conditioners
As soon as summer starts, people start looking for efficient means to cool themselves down. While regular air conditioners can do this job, some people opt for ventless portable air conditioners to meet their needs.
But what are they exactly? How do they work? Are they better than the regular AC units?
What are Ventless Portable Air Conditioners?
Ventless portable air conditioners are compact units that cool down the room without having an exhaust hose. This feature makes them exceptionally portable, allowing you to move them from one place to another.
Unlike window or central ACs, these units do not require installation and can be set-up easily without the need for hiring a professional too. Also called swamp coolers, ventless air conditioners perform best in dry environments.
How do Ventless Portable Air Conditioners Work?
These evaporative coolers function quite differently than a mini-split system or portable air conditioners. In regular vented ACs, heat is taken from inside the room and exchanged with fresh air from the outside. These units use refrigerant-based systems to cool down the outside air to the desired temperature and blow it into the room.
Meanwhile, a ventless AC does not require a hose to ventilate the room, minimizing the need to install it near a window. Instead, these air conditioners use a tank of water to cool down the warm air inside the room. The method is quite simple. The machine draws in the air from the room through a spongy damp medium, which takes in the heat from the air molecules. In return, the water in the sponge evaporates, cooling down the room temperature air.
By using the natural process of evaporation, this ventless air conditioner eliminates the need for the hose for heat exchange. Next, an integrated fan blows out the cool breeze inside the room to give you relief during hot days. The water reservoir is generally installed at the bottom of the air conditioner. While these AC models use pumps to keep the cooling pads damp, other models use gravity by keeping the tank at the top. Additionally, many models can use ice in the water tank to provide colder air.
If you want more efficient results, keep the ventless air conditioner near an open window or door to allow fresh air inside the room.
Benefits of a Ventless Portable Air Conditioner
Since they do not have an exhaust system or vents, these air conditioners are truly portable. Neither do you have to install them permanently, nor do you need an expert to set them up.
Apart from these, let us take a look at some other benefits:
- With low energy consumption operation, these AC units use fewer fuels and are eco-friendly.
- Instead of using compressors to cool and blow the air, the fan uses just 100 to 200W. Hence, these economic models save you a lot of money.
- Since they do not have any parts exposed to the environment, you do not have to waterproof anything.
- They add moisture to the air, making them perfect for use in dry arid regions.
- These models require minimum maintenance.
You need to consider a few points in order to choose the best ventless portable AC for your home.
First, determine how much cooling coverage is ideal for your room. This will require you to measure the room area in square feet.
The unit should be able to cover the entire space to ensure every corner of the room is comfortable and cool. Luma Comfort EC220W, for example, can be great as it offers excellent coverage.
Ventless Portable AC Runtime
This is important as some units only offer about 3 hours of run-time, which may not be enough.
Pick a unit that offers at least 8 hours of run-time so you can sleep without worries. The size of the tank plays a very important role here.
It can be frustrating to wake up in the middle of the night to take care of the ventless air cooler. You can avoid this by choosing a unit that has a timer option. You can set it to shut down automatically to save energy and reduce effort.
Other than this, pick a unit that sends low water alerts so that it doesn’t have to run when the water level is low as it can be bad for the unit.
Honeywell CO30XE 525 CFM can be a good pick, it has a remote control and an alert system as well.
It is important to make sure tha you pick a unit that offers excellent performance. Some factors that can influence the performance include customization options (fan speeds), the ability to use ice, etc.
Ease To Use
Consider how easy it is to use a unit. Some manufacturers offer detachable tanks for added ease. Plus, some portable ductless air conditioners even come with remote controls so that you do not have to move every time you want to change settings.
Luma Comfort EC110S 500 CFM can be an excellent pick as it offers good performance and is customizable as well.
Portable Air Conditioner Noise Level
You do not want to go for a unit that’s too noisy. It will disturb you and cause you to feel irritated so pay attention to the level of noise a unit creates when it is operating.
In the end, choose a portable air conditioner or ventless AC unit that fits your needs. All the three options discussed above are great, pick one that suits you the best.
Portable AC Units: Dual Hose vs Single Hose
In a portable air conditioning system, hoses are perhaps the most important setup element. Regardless of the number of hoses, the air conditioner has to pull in hot air and expel it outside through a vent while drawing in air from another one.
On a summer day, your air conditioner needs to regulate the heated air it produces, more than the heat outside. For this purpose, you need to choose from two different configurations for air conditioners. Here are some details for each to help you get an insight.
Single Hose Portable Air Conditioners
Single hose air conditioners are the most common and basic of air-cooling system designs. The technology uses an air compressor to draw out the heat from your room. In turn, this warmth is expelled outside through an outer unit, creating negative air pressure in the room.
The single-hose design works great for small and medium-sized rooms. Although, it proves to be inefficient in retaining the cool environment.
That’s because these units work with a single hose while the dual-hose unit works with two hoses. This means that at some point, enough warm air is entering your room to fill the air drawn out, as compared to the warm air the air conditioner is drawing out. This makes the unit work harder, which uses more energy.
However, if you need a highly portable machine, then the single hose unit is the one for you. You can easily move it closer to you when you need more cooling. Also, always check the BTU of a single hose unit before purchase, as they differ depending on the brand.
Dual Hose Portable Air Conditioners
Needless to say, this is the advanced version of a single hose unit and has two different exhaust hoses working together. Each of the hoses has different functions, which makes the machine operate more efficiently. One of them works as an exhaust pipe and draws out the hot air from the window. Simultaneously, the other hose draws air from the outside.
Here’s how it works:
The unit takes the warm air from the room, cools it down, and expels it out again. However, you’ll face a problem when using the single-hose unit for this, because in this case, the unit itself gets heated up.
To eliminate this issue, the second hose in the dual-hose unit takes air from the outside and uses it to cool down the compressor and condensing coils inside the machine. This helps the machine ensure consistent cooling for long intervals, even in spacious rooms.
Both of these types of air conditioners have their pros and cons. While the single-hose system is a bit primitive, it works great for small rooms, it is easier to move around, and is light on the pocket.
On the other hand, the dual-hose system is more expensive but has a longer system lifespan and works faster in larger rooms. In the end, the choice depends on your needs and your budget.
Tips to Make a Portable Air Conditioner More Efficient
Do you want to make your portable air conditioner as efficient as possible? With these tips not only can you get your money’s worth, but also ensure more efficient operation of your appliance.
It may not seem important but the installation location of your portable air conditioner is important. If you want your AC to work better, avoid sunspots and high humidity areas when installing your air conditioning unit.
It is only through ventilation that you can get rid of hot air in the compressor of your AC. Proper ventilation not only saves your AC from overheating but also helps maintain the temperature of the room.
Keep the Exhaust Hose Straight
Along with ventilation, taking care of the exhaust hose can also increase the efficiency of your portable air conditioner. Make sure you minimize coils, kinks, and twists in the hose as it should remain as straight as possible to let moisture pass through.
Clean Air Filter
This goes without saying, but regular cleaning of your AC is very important. You need to clean the filters of your air conditioning device every 6 to 8 weeks. This can help you stretch the life of your portable AC.
When you’re not using the air conditioner, we suggest you clean the filter and drain the water container completely before storing it. It should be kept in a safe and dry place. Avoid storing it in places, such as the garage or patio with extreme temperatures.
