The device absorbs dry hot air from one side and converts it into colder, wetter steam to be discharged from the other side. If you want to create cool air without the drying temperature of an ordinary air conditioning system, then Tundra Breeze AC may be the right choice for you.

Portable air conditioners all promise similar benefits. They all claim to lower the air temperature in a small space while providing a compact and portable design.

Unfortunately, not all portable AC devices can deliver on this promise. Some just spread water vapor around your home without cooling the air. The others broke down after a few months.

In order to separate the best and worst portable air cooling devices from each other, we used the following indicators:

Cooling efficiency: Some portable air coolers are not very effective. Others will produce surprisingly cold temperatures. The biggest ranking factor we use is the cooling effect. You are buying a portable air conditioner to create a cool temperature in your home. The best units above achieved these goals.

Humidification effect: Many people buy portable air conditioners not only for cool temperature, but also for humidity. A good portable air conditioner is a humidifier, which rolls the air conditioner into a convenient device. We also considered the humidification effect of the unit in the ranking.

Style, design and aesthetics: This is not our most important ranking factor, but we do consider style, design and aesthetics in the ranking. Some of the portable air conditioners above have been invested in quality design features, making them ideal choices to complement your home or bedroom decor. Others look plain and boring.

Easy to use: Regardless of your technical skills, most portable air conditioners are easy to use. For most of the above devices, you just need to fill them with water and ice, plug them in, and let them run. That's it.

Additional function: The main goal of the portable air conditioner is to cool the room. However, many of the portable air conditioners listed above also generate moisture, filter the air, and even use ultraviolet light to remove bacteria from the air. We considered these additional features in our rankings.

Return Policy: Some portable air conditioners do not work well. If you are not satisfied with a unit, you should be able to return it. However, the return policy of some portable air conditioners is surprisingly strict. If a company deliberately makes returns difficult (or does not provide any returns), then their ranking will drop. All reputable manufacturers support their portable air conditioners so that they can easily apply for refunds if they are not satisfied.

Customization options: Depending on the time and temperature of the day, you may need different degrees of coolness. For example, some people want a cool temperature all night, while others want a fan that is gentle and cool all day. We considered customization options in the ranking.

Ice tray, water curtain and atomization device: Most portable air conditioners use ice tray, water curtain and atomization device to generate cold vapor. These devices absorb hot, dry air through one side and expel it as cooler, cleaner air through the other side. Some ice trays, water curtains and atomizers are better than others.

Price and value: Some people want to buy a portable air conditioner for $15. Others want to spend 200 dollars. We have launched portable air conditioners at various price points, allowing you to easily choose the air conditioner that fits your budget. However, at all price points, we ensure that portable air conditioners are worth the money. No one wants to be ripped off.

Customer reviews: Although we personally tested each of the portable AC devices listed above, we also considered customer reviews in our rankings. Customers test portable communication devices under various weather conditions, humidity levels and temperatures. Although we are confident in our tests, we also consider customer reviews.

Transparency: Some portable air-conditioning companies provide user manuals and other information in advance. Other companies even refused to disclose basic information-such as the size of the water tank or the capacity of the battery. We considered transparency in the ranking. Where to use portable air conditioners

Most are powered by a USB port and battery, providing power consumption similar to that of a smartphone or tablet.

2) Custom temperature: Some portable air conditioners have a thermostat, while others do not. Most portable air conditioners let you choose from three to five temperature levels. Even if you can't customize the temperature to a specific level, you can also choose how hot or cold you want the room to be-similar to a whole house air conditioner.

How does the portable air conditioner work?

Portable air conditioners work differently. The portable air conditioners listed above use basic technology to produce a lower temperature, passing air through a water curtain to produce cold vapor. They are designed for smaller spaces, including bedrooms and apartments.

Other portable air conditioners are more advanced. They can spread cool temperatures in a larger space. For example, some have 12,000 BTU and use hoses to connect to outside air. Some use a single-hose design, while others use a dual-hose design.

When you buy a premium air conditioner, you will get a device filled with refrigerant (used to cool the air), a compressor (used to compress the refrigerant), and a fan (used to move the air). This is similar to the working principle of a whole house air conditioning system. The device sucks in air from the outside, uses refrigerants and compressors to cool the air, and then circulates the air in your home.

Advanced air conditioners are suitable for larger homes and spaces. However, they can be very noisy. Some people use too much electricity. They also absorb moisture in the air, making the temperature in your home drier.

The above-mentioned air cooling system works differently. They will add moisture to your home, not remove it. They create cool temperatures without creating a dry environment. They still extract heat from the air-but they do not need to use refrigerants or compressors.

The following is the basic process used by the above air cooling system to generate cool temperatures:

Step 1) The equipment draws in dry hot air from one side.

Step 2) Air enters the unit and passes through the water curtain. The water curtain is connected to the hydration chamber and, in many cases, to the ice tray. The water curtain was cold and wet.

Step 3) When air passes through the water curtain, it will cause the water in the water curtain to evaporate. Evaporation requires heat. As the water evaporates, it removes heat from the air, creating a cooler and cleaner temperature.

Step 4) The fan blows the cool, humid air out of the other end of the device, spreading the lower temperature throughout the room or home.

That's it! Some portable air conditioners also have ultraviolet lamps, bacterial filters and other advanced features. However, most devices use the steps listed above to cool the air around you. Frequently asked questions about portable air conditioners

Q: Why is there ultraviolet light on my air conditioner?

Answer: Some portable air conditioners use UV and other filtering systems. According to data from the American Academy of Allergy, 50% of diseases are aggravated or caused by indoor polluted air.

Answer: The portable air-conditioning devices listed above are very suitable for cooling the home without air-conditioning. You can lower the temperature in your home without the need for an entire home HVAC system or similar systems.

Question: How does the central air-conditioning system work?

Answer: The central air-conditioning system uses a compressor to pump refrigerant into the system, collects heat and humidity from the room and discharges it from the home, thereby reducing the temperature of the entire home. The high temperature from your home is pumped to the cooling indoor coil (usually located on the top of your furnace). The heat in the air is transferred to the coil, reducing the air temperature. Then the hot air is pumped outside, while the cold air circulates inside.

Q: Why does my air conditioner blow out the air?

Answer: Modern HVAC systems reduce the air temperature while removing moisture. This is why many households feel dry after running the air conditioner for a long time. Some people experience dry skin and other problems when running the air conditioner for a long time. The portable air conditioners listed above will increase the moisture in the air instead of removing it.

Q: What is Energy Star?
