How Do Outdoor Air Conditioners Work?

Understanding how outdoor air conditioners work can help you make an informed choice based on your cooling needs. Unlike evaporative coolers, air conditioners operate using a compressor, condenser coil, and a fan. The heat from inside your home is absorbed and transferred to the refrigerant, which is then pumped to the outdoor unit. The heat is dispersed outside, while the cooled refrigerant is pumped back indoors, repeating the process.

Evaporative coolers, on the other hand, operate on the principle of evaporation. Hot air is drawn into the cooler, passing over wet cooling pads. The cool and moisturized air is then released into the room or space, providing quick relief from the heat.

How Humidity Affects Evaporative Cooling

One common misconception is that evaporative coolers are ineffective in humid climates. While extremely high humidity can impact their performance, evaporative coolers can provide relief in any climate. They work by cooling the air through the evaporation of water. However, they are most effective in climates where the average humidity level is less than 30%. As the humidity rises, the cooling capability decreases, affecting the temperature difference between the inside and outside of the space.

To determine if evaporative cooling will be effective, you can measure the wet bulb temperature using a moist cloth and a thermometer. The temperature measured represents the minimum temperature achievable through evaporative cooling. It's important to note that evaporative cooling systems naturally cool the air using water.

Types of Outdoor Air Conditioners

There are several types of outdoor air conditioners and evaporative coolers available. Let's explore the different types:

Outdoor Air Conditioners:

  • Central air conditioners: These use a split system to regulate air through installed ducts.
  • Window air conditioners: Designed specifically for use on windows.
  • Floor-mounted air conditioners: Designed to be placed on the floor, around 6 inches higher.
  • Ductless mini-split: Ideal for modern homes, combining outdoor and indoor AC units.
  • Geothermal air conditioners: Circulate water through piping with a loop in your home.
  • Hybrid/dual fuel air conditioners: Utilize a combination of gas furnaces and electric air-source heat pumps.
  • Smart air conditioners: IoT-enabled, including mini-split, portable, and window units.
  • Portable air conditioners: Freestanding units similar to window ACs, but with the flexibility to be easily moved.

Evaporative Coolers:

  • Direct evaporative coolers: Use water vapor's natural cooling properties to lower air temperature.
  • Indirect evaporative coolers: Do not add humidity to the air and allow for cooling to lower temperatures.
  • Mounted coolers: Can be mounted on the ground, window, or roof.

What Size of Outdoor Air Conditioner for Patio Do I Need?

Determining the suitable size of an evaporative cooler for your space is crucial. Evaporative coolers are rated by cubic feet per minute (CFM) of the air they deliver. Most coolers available range from 3,000 to 25,000 CFM. Manufacturers recommend providing enough air-moving capacity for approximately 20 to 40 air changes per hour, depending on the climate.

To find the right evaporative cooler for your space, follow these steps:

  1. Calculate the square footage of your space and multiply it by the ceiling height.
  2. Divide the result by 2.
  3. The result is the CFM rating of the swamp cooler you should buy.

For example, a small swamp cooler can effectively cool a space of about 300 sq. ft.

How to Choose an Outdoor Air Conditioner

To choose the best outdoor evaporative cooler, consider the following factors:

  1. Cooling capacity: Check the CFM rating to ensure it is suitable for your space.
  2. Cost: Determine your budget and find a cooler that offers the best value for money.
  3. Portability: Consider the weight, wheels, and handles for easy movement.
  4. Efficiency: Look for features like adjustable louvers, multiple cooling modes, and programmable timers.
  5. Size: Ensure the cooler is appropriate for your space to maximize its effectiveness.
