Small Portable Air Conditioners

LORIZA Portable Handheld Mini Cool Air ConditionerIf you are looking for an even smaller-scale device to cool down, the best air conditioner for you might be a hand-held or a mini portable air conditioner. Some small portable ac units work exactly like their larger counterparts, while others are hand-held devices that use internal evaporative cooling and a small fan to cool the air around them.

Hot air is drawn inside the tiny air conditioner using a wet sponge and then cooled as it passes through. Compact air conditioners like these work best in dry heat rather than humidity. There is a substantial difference between the largest and smallest air conditioners in this category, which means there are multitudes of options to suit a wide variety of needs.

Some of the smallest portable air conditioners and best-rated portable air conditioners include the Frigidaire Mini Window Air Conditioner, the Senville Mini Split Air Conditioner and Heat Pump, and the LORIZA Portable Handheld Mini Cool Air Conditioner. All of these are a great choice for a compact portable air conditioner.

Portable Air Conditioners for Cars

Portable Air Conditioners for CarsPortable air conditioners for cars are an excellent option for many people including those who have a vehicle that have an air conditioning unit that is no longer functioning and requires endless amounts of coolant and recharge to be added, or for those who camp out in their vehicle that need a cooling unit that doesn’t require the vehicle running, or depleting the battery.

Instead of paying thousands to repair your current system, or pay the excess gas and battery prices, a portable air conditioner for your vehicle can be purchased. Portable car air conditioners are units that run off of the 12V outlet located in the cigarette lighter.

The portable A/C for cars mostly have built in batteries that allow them to run for several hours without needing to be recharged, have a standby time of much longer than that. They have many of the same functionality of a household unit; like adjustable, digital temperature gages, multiple fan speeds, and adjustable timers and settings, making them a great mobile air conditioner.

Desktop Air Conditioners

Desktop Air ConditionersDesktop air conditioners are great for those situations when your workspace is exceptionally hot during the winter months because the office heater thermostat is broken, or in the summer when the air can’t keep up.

The Office Portable Mini Fan is an excellent option for those who need an upright air conditioner to put on their desk to cool the area for a situation such as that. This little unit packs quite a punch, and can be used as both a fan and an air conditioning unit.

Powered by both a USB and/or three small batteries, this unit can go anywhere because finding a power outlet is not essential. Anywhere you would have your computer, you can use this system. Desktop air conditioners are special because they are manufactured to take up little space, have little to no power consumption, but still provide a reasonable cooling output for the space they are designed for.

Quiet Portable Air Conditioners

Finding the quietest portable air conditioners can be a difficult task to accomplish, because manufacturers don’t always post that information in the product descriptions, but determining truly what is the quietest portable air conditioner can be established from customer feedback and reviews.

Quiet Portable Air ConditionersThe Honeywell MN12CES is a near silent portable air conditioner, and is great for quiet rooms. It has adjustable fan speeds and timers so it can be programmed to be nearly silent when necessary, or louder and more effective when there are no listeners around to hear it.

Quiet AC units are handy for those situations when you want to cool a room down, but don’t want to create a large amount of noise doing so, whether in a social gathering or in a child’s room who is sleeping.

The possibilities for where keeping a portable air conditioner quiet are endless, so a unit like the Whynter dual hose air conditioner is a great choice. It has the ability to rapidly cool the area down, and turn all the fans to a slow circulation speed to keep the air moving and cool, but not make much noise.

Portable air conditioners for the bedroom are more common in recent years because of the failing central air systems and the ease of a portable system to replace it. A quiet portable AC can effectively eliminate the need for a central AC unit, and be more energy efficient in the process.

If you are looking for the best portable room air conditioner, consider finding one that is incredibly quiet. Read portable room air conditioner reviews to determine their noise level.

Most Energy Efficient Portable Air Conditioner

NewAir AC-12000EEnergy saver portable air conditioners set themselves apart from their competing models because they are designed to use their energy differently; in a more efficient manner.

The NewAir AC-12000E is a good example of this, as it is ranked as an energy efficient model that is meant to efficiently cool an area while still maintaining a good quality of air and not drawing excessive power.

Some models can be guilty of power leaching, which is term that is used to describe the unneeded resistance within the unit that uses more power than it is required, costing you more money in the long run.

The Whynter ARC-142BX is also a great low energy air conditioner and a contender for the best of the energy efficient portable air conditioners.

Self-Evaporating Portable Air Conditioners

Self-Evaporating Portable Air ConditionersHaving a self evaporating portable air conditioner is essential if you want a unit that is hands free for much of its operating time. Self-evaporating is referring to the units ability to use the water that condenses from the air and using it to cool the warm air, thus expelling it back into the air.

The Honeywell MN12CES is a great example of this, as it is a bucket-less design that is totally self contained, not requiring users to empty any containers from condensed water. The DeLonghi America portable air conditioner also fits this description, as does many other models on the market.

Non-Vented Portable Air Conditioner

Non-Vented Portable Air ConditionerFreestanding air conditioner with no venting is a common desirable trait that many have for their portable air conditioners. Vented air conditioners require either a window mount vent or a hose that is connected to the back of the unit that is run to a vent hole to allow warm or excess air to be ported away from the cooled area.

The Honeywell MN10CESBB Vent-less portable air conditioner is a great portable air conditioner for the bedroom, because it can be placed anywhere without having to worry about venting and hoses.

The Luma Comfort EC110S is also an excellent option for a smaller portable air conditioner without a vent. The unit can be placed virtually anywhere it will fit, and cool an area up to 250 square feet, making it a great unit for those smaller enclosed areas.

Portable air conditioners are small self-contained units that are used to cool single rooms. They make a great alternative to window units because most portable air conditioners have wheels and can be moved from room to room.

These portable ac units are simple to install and provide excellent support for AC systems that are older or less powerful.

Compact portable air conditioners can be utilized throughout the home in bedrooms, dens, computer rooms, garage conversions, and room additions.

How does a portable air conditioner work?

Portable air conditioners are designed to function just like window units or central air conditioning systems. Air conditioners intake fresh air and expel hot air outdoors to remove it from a building. Window units are positioned in the room so that they can expel air right outside the wall where they are placed, while central air conditioning units are installed outdoors where they can intake cooler air and expel hot air directly.

Portable air conditioners simply use a small tube to achieve this same goal without the hassle of installation. One end of the tube is connected to the portable unit, while the other end is extended through an opening such as a window, door, or mail slot. The portable air conditioner and its tube are both lightweight, which makes them very easily moveable.

Just like other air conditioning systems, portable air conditioners use refrigeration chemicals, a compressor, a condenser, and an evaporator. What set them apart from window or central models is that their compressors and condensers are located inside the interior space that is cooling.

Refrigeration chemicals are passed through the compressor as a low-pressure gas so that the molecules can be tightly packed together. This increases their energy and temperature levels. This warm, high-pressure gas enters the condenser where it is simultaneously transformed into a liquid and cooled.

This liquid passes into the evaporator, and it turns back into a gas with the drop in pressure. The cool air is then released into the interior space and gas returns to the compressor to repeat the same cycle. Portable air conditioners also come with a receptacle to collect any excess condensation. This can be emptied manually or drained with a hose and discarded.

Portable air conditioners function best when they are placed nearer to an opening than the center of a room because it allows them to maximize the amount of hot hair they expel outside. It is a good idea to insulate the exhaust tube with rags to prevent it from radiating heat into the room.

Factors to Consider When Purchasing a Portable Air Conditioner

What is the best potable air conditioner? To ensure the best purchasing experience possible, there are a few factors to consider when buying a portable air conditioner. Although there is a plethora of options to choose from, these points can assist in narrowing your focus. The best portable air conditioners will exhibit high ratings in a few key qualities. Here are some guidelines for picking out top-rated portable air conditioners:

Choose the proper BTU rating.Choose the proper BTU rating.

Factors to Consider When Purchasing a Portable Air Conditioner

Courtesy of Rick Cameron

BTU (British Thermal Unit) measures the amount of heat necessary to raise the temperature of 1lb of water by one degree Fahrenheit and is the equivalent of 1,055 Joules. Essentially, a greater BTU rating means greater cooling power, which will maximize your portable air conditioner efficiency.

Although portable air conditioners do not have the same cooling capacity as, for instance, a window unit, there are still some helpful guidelines that can maximize their efficiency depending on the size of the room. Portable air conditioners are best utilized at:

  • 7500 BTU: 150 square feet
  • 9000 BTU: 250 square feet
  • 10,000 BTU: 300 square feet
  • 12,000 BTU: 400 square feet
  • 13,000 BTU: 450 square feet
  • 14,000 BTU: 500 square feet

The maximum suggested room size according to the manufacturer may differ from these suggestions, and it is important to remember that an excessive amount of heat will impede any type of air conditioner. Remember, an air conditioner without enough cooling power will not cool your space adequately. However, an air conditioner with too much power will fail to dehumidify your space.

Choose the proper BTU rating.Consider the EE

The Energy Efficiency Ratio (EER) indicates how much an air conditioner can cool a room in relation to the energy it uses. The higher the EER, the more energy efficient the unit is. The number is calculated by dividing the BTU by the wattage. The minimum requirement for the EER by law is 10.

Choose the proper BTU rating.Inspect different condensate disposal methods.

Water that is dehumidified from the air is called condensate. It is collected in a bucket inside of portable air conditioners, but different models dispose of it three different ways.

Choose the proper BTU rating.Drip

Some models have internal buckets that fill up every 2-8 hours and must be emptied by hand.

Choose the proper BTU rating.Partial Drip

Other models evaporate the vast majority of the condensate, which is then vented out of the exhaust hose. The rest fills a bucket which must be removed by hand ever 12 hours-several days. Occasionally models will be equipped with a drain pump that allows users to pump the condensate out through a small tube within the exhaust hose.

Choose the proper BTU rating.No Drip
