Some models offer the option of adding an ice pack to further cool the air the fan blows out into the room. Varying fan speeds, oscillating functions and a remote control are also useful features.
A swamp cooler is often a term reserved for a whole-house evaporative air conditioning unit, while evaporative coolers can be any size — including compact, portable evaporative coolers.
Permanent swamp coolers are large units designed to cool a whole house. Cool air flows down from roof-mounted systems, or it can be piped through ductwork to be directed to any location you like. Evaporative coolers have two major advantages over traditional air conditioners : energy efficiency and sustainability.
Both are due to the fact that evaporative coolers use far less electricity to operate; in fact, a standard air conditioner can use up to seven times as many watts of electricity. This is because, in general, evaporative coolers only need to run the fan that draws airflow over the cooling pad. Standard air conditioning systems , on the other hand, rely on a compressor to press liquid refrigerant into a smaller space and then move it across a heat exchanger to pull heat out of the air.
This process requires a great deal of electricity to accomplish, in addition to the fan that send cold air out into the room. Using less electricity with an evaporative cooler means lowering your carbon footprint as well as paying less on your utility bills.
It should also be noted that evaporative coolers use only water and no chemical refrigerants, which are harmful to the ozone layer. This makes sense, of course, when you pause to break down how they work. Because these coolers depend on water being able to evaporate into the atmosphere, having a house full of dry air makes this process much more efficient.
The water molecules can separate and float off into dry air much more easily than they can into humid air, which is already pretty saturated with water. In these arid locations, water will evaporate quickly and cool your air well. The other reason that evaporative coolers are better in the Southwest than in other regions is because using them actually boosts the humidity level in your home.
As the water evaporates , it leaves the cooler and stays in the air in your home. If you live in the desert, this can be a real bonus for helping you stay hydrated and to keep your skin in good shape. In humid climates , however, this could be a deal breaker. Know Your Humidity Levels. To understand why, consider how your body feels on a muggy day. When you are hot, your body sweats to cool you naturally through the process of evaporation your sweat evaporates into the air and cools you. The same thing happens with an evaporative cooler in a humid region: It pumps more moisture into the air, making it even more humid — and less likely that water will evaporate and make you feel cool.
The bottom line? Depending on your needs, you will consider if an evaporative cooler is built to function successfully in your home. An evaporative cooler generally has four main components :. These components work together to cool the air it is bringing into your home. The following steps are the basic aspects of a working evaporative cooler:. There are two different types of evaporative coolers, which can slightly alter how the air is taken in and expelled out of the machine:.
With a whole-house evaporative cooler, it can be installed in various locations :. An evaporative cooler can be very useful, as it is an environmentally friendly and economical purchase.
If you have been convinced to purchase an evaporative cooler, you may be wondering which option is best for you! Look no further than the helpful chart below, which has collated important information on the different types of evaporative coolers.
If you are still confused about what evaporative cooler is the right choice for you, reach out to a local HVAC service or go to a home improvement store for guidance. Many evaporative coolers have the same features, but you can find a model that suits all your needs. Many times, people will think an evaporative cooler will cool just as well as an air conditioner.
This statement is only true in some regions and even then during specific times of the year. As you can see, there are quite a few features that you can choose from when shopping for an evaporative cooler. If you want to buy an evaporative cooler, it may be helpful to read online reviews or go into a store to compare various models.
Evaporative coolers really can cool your house. These coolers are very popular out in the Western United States, where dry heat is a major obstacle. If you are not living in an area where dry heat is prevalent, you can still use an evaporative cooler. Try using an evaporative cooler in the transitions between spring and summer or summer and fall.
Evaporative coolers work specifically by adding water molecules to the air, which increases humidity. Filter that reduces air pollution. Great for dry climates. A residential central air conditioning system is an intricate device, and all its components need to work together seamlessly for October 28, By Intelligent Air Services. How Does Evaporative Cooling Work? What differs between a standard central AC and an evaporative cooler is the cooling mechanism.
A standard air conditioner circulates refrigerant to pump heat from inside the house to the outside. Electrical power goes to a compressor to super-heat the refrigerant and places it under extreme pressure so it circulates. Electricity also powers a set of exhaust and blower fans. An evaporative cooler uses the water to cool off air brought in from outside the house. Water is pumped onto the pads the air passes over, and the air loses its heat to the water—this is evaporative cooling.
Electrical power goes to the pumps wetting the pads and to the blower fan.
