What is a Portable AC

Before we jump into how they works, we need to cover what an AC is. Being able to distinguish the different types of air conditioning is important. The build of a these units is small and it works best for cooling off one room. They normally sit on the ground and offer great portability when compared to windowed AC.

How does it Work?

When taking a portable AC with you, it may have crossed your mind how exactly they work. The fascinating mechanisms inside of these devices help to produce cool air for you. But, what exactly are these mechanisms that doing? Today, we will be going over how AC works and see how some of these mechanisms cut down electricity consumption. There are many different styles and models of out there, but we will be going over the general concept of the AC.

Setting Up an AC

Every  AC is different, but for the most part, you can set up your  AC in a similar fashion. Doing so is quite simple. Although these are ACs, they still need to circulate air and dump some out. Most  AC will come with a window kit to set up. Your  AC unit should come with clear instructions to set this up. After getting your window kit installed, your AC unit will be ready to use. Removing your window kit and moving it around is also extremely easy to aid in the portability.

Handling Water

So, since  AC units work similar to traditional window units, you may be curious what happens to the water build up. Knowing how ACs work, it has to go somewhere. This is dependent on the model that you have. There are different types of ACs and each deal with this water build up different.

Drain Hose:

Some people will utilize a drain hose to get rid of the water that builds up in the AC. If you need to use a drain hose, the unit will likely come with one. Finding the drain hole on the unit should not be hard after following the user manual and connecting the hose to the drain hole is all the setup you need here. In addition to the drain hose, there is also another component called a condensation drain which basically does the same thing as a drain hose except it typically is longer and stretches outside of a window.

What are the True Electricity Costs ?

The summer is a fun time. Going out and enjoying the beach is a wonderful pastime. When you arrive home though, things can get a little out of hand. With the scorching heat coming down on you, AC seems the only way to stay cool. So, this leads you to search online for a good AC.

Now that you know how they work and have found one, there is only one question that remains: how much does AC electricity costs? Yes, these units are not nearly as expensive as window units, but are they more cost efficient? That is what we will be discussing today.

Choosing  your unit

AC electricity costs highly depend on the type of  AC that you purchase. They come in all different shapes and sizes and picking the right one can be tough. When deciding on the right AC, it is important that you keep these aspects in mind

BTUs or British Thermal Unit

This is a measurement for air conditioning units that helps you determine the amount of cooling power in an air conditioner. The higher the BTU is, the more power that you will get out of the AC unit you buy. There are BTU calculators available for you to use online that should help you with this step. Determine the size of the room that you are cooling and select a BTU that will be able to handle that room size.

 Size

With an indirect correlation to the BTU, the size of the  AC is also important. Having a larger  AC will allow for you to cool off a larger sized room when compared to a smallest ac unit. This means more BTU, and consequently, more electricity cost. When picking a good  AC unit, make sure to keep this in mind.

Other Features

Features do a great job of making or breaking products. There are some AC units that have dual functionality. From  AC units that can act as an air purifier to those that work as humidifiers, there are tons of different styles available. We highly recommend sticking with an AC with features that you will find useful in the future.

Costs

Now, let’s talk about costs. Costs are highly relative to the features listed above, however, for the most part, you can easily break down the costs of your  AC. Make sure to find out the BTU of your device. BTUs can then be converted to kilowatts per hour and measured by price. As a general rule of thumb, 10,000 BTU is about $3.75 per hour based off of California electricity costs.

Single Vs. Double Exhaust Hose

These units that are equipped with a single hose capture the air from the surrounding area, cool it down, and then blow most of it back into the room. The remaining is used to cool the unit, and is then expelled through the exhaust. Because the air from inside the room is used to cool the appliance, the pressure tends to be negative, which results in warm air flowing into the room to restore the equilibrium. For a more in depth article of how portables ac works click the link.

Dual hose portable units capture the air from the surrounding area, cool it and then return it all to the original space. Cooling ambient temperature results in the accumulation of heat in the appliance. The unit draws air from outside through a separate hose, cools the compressor, and then expels it through the exhaust hose, ensuring that the pressure is unaffected.

Check the energy rating of the unit that you purchase as the use of fans and the method used to chill the compressor can influence its energy efficiency.

Unique Features to Consider

  • Programmable Thermostat – allows you to determine the exact temperature that you require in the affected space. Once the ambient temperature reaches the pre- set condition, the AC will turn off. Some of the top units will even allow you to pre-program the unit to switch on at a specified time.
  • Auto Drain System – changes the water caused by condensation into steam so that it can be vented off. You can also consider a window vent kit if your unit needs to be vented. (R)
  • Remote Control – allows you to control the appliance without approaching it.
  • Heater and AC combination – offering the option of both heating and cooling the room, so it can be used winter and summer.
  • Dehumidifier - helps to remove moisture from the air. Being able to handle humidity is particularly important in the hot summer months.
Single Vs. Double Exhaust Hose

It is not necessary to struggle through sweltering temperatures this summer. Whether you’re looking for great portability or cooling ability there are options out there. By considering the ambient requirements, cost, and premium features of the best units, you could chill out in the summer months, no matter your location.
