Differences Between an Air Cooler and an Air Conditioner

Let us take a closer look at some differences between an air cooler and an air conditioner in multiple aspects related to the working of each device.

  • Cooling Method. A mini AC unit uses a chemical coolant called a refrigerant to cool the air. It converts from vapor to liquid form and passes through indoor evaporative coils, thus lowering the temperature. Air coolers have a simpler cooling method of passing air through wet absorbent pads. There is no risk of refrigerant leakage involved, and you only need water to maintain the temperature.
  • Energy Efficiency. Air conditioners take the help of compressors to cool down a room, which requires massive amounts of electricity. On the other hand, air coolers use motors to pull and cool air, which is a much more energy-efficient method of cooling.
  • Climate Considerations. Air coolers are recommended for use only in areas with low humidity, as they hydrate the air too. Air conditioners can be used anywhere, since they circulate the internal air and cool it down with the help of powerful condensers. But while using them you might need a humidifier, as they do dry out the air.
  • Maintenance. Miniature air conditioner units are very costly when it comes to their maintenance. It requires experienced labor in addition to a significant amount of money, whereas air coolers are budget-friendly and easy to maintain.

From the above-mentioned differences we get a clear idea that mini air coolers use a more straightforward, energy-efficient cooling method than commercial air conditioners. The maintenance cost of these easy-to-use devices is also lesser than air conditioners. However, coolers' only drawback is that they are more efficient in dry and arid areas, while air conditioners are universally operated.

What to Consider When Buying a Mini Air Cooler

Choosing a mini air cooler needs precision

What to Consider When Buying a Mini Air Cooler

Let us take a closer peek at some factors that should be considered before choosing or purchasing a miniature swamp cooler or any other air conditioner.

  • Size. The dimensions of the appliance are the primary factor to keep in mind while seeking out any sort of air-cooling device. First, you should measure your room. Then, proceed to choose among particularly-sized cooler options. For a residential or professional space, divide the volume of the user's room in cubic feet by two (minutes) and get the needed number in cubic feet/minute (cfm).
  • Cooling Power. Personal air coolers of distinguishable varieties sport different cooling powers. You should choose a mini air cooler with a cooling capacity to cool your space conveniently. The average minimum for cooling area is 40 square feet. However, the real cooling power depends on the AC type and the size of your space.
    If you are looking to cool your whole bedroom, for example, you may want to consider air conditioners.
  • Energy Efficiency. Selecting a mini cooler that packs tons of power might only lead to a greater electricity consumption than is necessary to cool your space. Therefore, you should choose an energy-efficient air conditioner that cools down your space by consuming as little electricity as possible. It’s a great deal if you’ve found something below 10 Watts.
  • Warranty and Support. One must only opt for a cooler manufactured by a manufacturer that provides a warranty and guarantees excellent and efficient after-sales support. Most companies nowadays that manufacture air-cooling machines provide both. To minimize the risk of new repairs, avoid materials for AC units that cost cheaper than $30. It’s better to invest in quality right away.
  • Noise Level. Depending on the model, the quality of the device, and the fan's speed settings, an air conditioning unit can emit noise of anywhere between 30 and 82 decibels. In contrast, a desk air cooler makes minimal noise while functioning, with a sound rating between 25 and 45 decibels.
  • Versatility. A modern mini air conditioner can provide you with fresh air and take care of the quality of the air you breathe by humidifying and purifying it. So, don't settle for the basic setup; use the versatility modern technologies offer.
  • Adjustable Speeds. Almost all miniature swamp cooler options manufactured these days come with different speed settings. When shopping for one, you must always choose one that features several speed-adjusting settings for your comfort and convenience.
  • Water Tank Capacity (for Evaporative Air Coolers). When you have a large space you need to cool down, you must choose a mini evaporative air cooler featuring a huge tank capacity that starts above 300 milliliters. Similarly, if you need one for usage in a small room, a mini air cooler with a lower capacity will do the trick.

Why a Mini Air Conditioner Is Better Than a Large One

When deciding on your new air conditioner, you can suppose larger is better. However, this is not ultimately true. Of course, the larger gadget can produce a more powerful airflow, but you should consider whether you really need it. Here we provide several arguments for buying a small air conditioning unit.

  • Size. The primary advantage of a tiny air conditioners is their compact shape that can be accommodated conveniently in a small space within your room or office. The portable nature of these appliances adds an extra edge to their presence. Are you feeling sultry in your living room? Transport your device for a relaxed TV session, or you can have a relieving afternoon nap in your bedroom.
  • Expenses. You’ll pay more for a larger device, not only in the initial transaction but also in terms of utility costs. Review your utility bills before choosing a larger air conditioner — the next payment may upset you. Even if you choose the A+ device with minimal energy consumption, it needs power to run.  
  • Installation and movement. You can install or move a smaller air conditioner by yourself. However, the larger units can be as massive as 213 pounds (almost 100 kg). One person can hardly complete the installation or movement, and you'll need some assistance. If you plan to hire a serviceman for this, do not forget to add this payment to the total amount.
  • Cycle length. There is a specific problem you can face when your air conditioner is oversized. Most air conditioners have a temperature sensor. When the device cools the room too fast, the cycle lengths can take just ten minutes. First, this sharp temperature gap is not good for your body. Health care professionals are familiar with this problem — they record a growing number of respiratory infections due to air conditioners' impact in summer.
  • Cooling and noise performance. Mini air conditioners often have the ultimate combo of noise and cooling performance, when they efficiently cool the space next to you and still operate in a whisper-quiet mode.

Second, this cycle is too short for changing humidity levels. If you want to cool down the room AND change the humidity level — decrease or increase it — you need time for this. Properly sized air conditioners run longer but more effectively.

At last, the frequent but short cycles wear your equipment out — the number of starting-up and shutting-down cycles increases because the device satisfies the cooling load quickly. After a certain number of cycles, you will face the necessity of repair work.  

It would be unfair to say that large air coolers do not work at all. For a shopping mall, offices, halls, and large homes, you will obviously need something massive and powerful to cool the air, especially in hot climates.

However, if you live in a small house or apartment, it does matter for you. You're better off buying an additional mini air conditioner for a bedroom or work area to make it comfortable. Cooling your space by zones would be more reasonable than installing a huge system that will not work correctly. You can find a list of the top five mini coolers in the next section.
