What Is an Evaporative Air Cooler?

Evaporative air cooler

An evaporative air cooler is a type of air conditioning system that cools the air in a room by evaporating water. It is a different type of air conditioner from other systems that use absorption refrigeration and vapor-compression cycles. An evaporative cooler is one of the most efficient and effective ways to keep a room cool.

Indirect evaporative cooling

Indirect evaporative cooling systems can reduce your air conditioning costs by up to 60 percent. This type of cooling works by dissipating the heat in the air and chilling the entire space. It works at a constant rate, so it doesn’t need to be switched on or off when the weather changes.

The indirect evaporative cooling process works by utilizing the same principles as direct evaporative cooling, but it uses a heat exchanger to cool the air. The process takes place in the humidification section of a building and involves two air streams. One of the airstreams passes over the inner wall of the heat exchanger, while the other passes through the outer wall. The water in the air evaporates, transferring the heat to the exterior wall, thus cooling the airstream.

Indirect evaporative cooling can save energy because the cooling process requires less power than conventional air conditioners. In fact, it uses up to 55% less power than conventional air conditioners. In addition, it performs almost as well in hot and dry climates as a conventional air conditioner.

Another benefit of indirect evaporative cooling is that it does not add moisture to the primary air stream. The secondary air source removes the heat from the primary air stream, lowering the wet-bulb temperature. However, it is limited by the efficiency of the heat exchanger and the amount of secondary air that is pre-cooled.

Evaporative cooling is a versatile air conditioning solution, which can be used in a variety of industries. It is also extremely energy efficient, environmentally conscious, and cost-effective. Unlike mechanical refrigeration, evaporative cooling saves money. Compared to a mechanical air conditioning system, it produces fewer emissions.

Energy efficiency

An evaporative air cooler is an environmentally friendly HVAC system that cools air without using refrigerants. It has improved efficiency and is also less expensive than traditional refrigeration systems. The main difference between a typical evaporating air cooler and a M-cycle cooler is that the former uses less water and electricity, while the latter does not.

An evaporative air cooler is 85% efficient when operating at a constant air temperature. The air inside it is 80-90% relative humidity. This can be high enough to affect the rate of evaporation of moisture from the skin. High humidity also accelerates the corrosion of dust and electronics. The high humidity also causes water to condense, which shortens the life of the equipment and reduces its performance. Also, the humidity levels outside the building can affect the evaporative air cooler’s efficiency, since it requires a constant supply of water to function.

Another factor that affects energy efficiency is where to place the cooler. Smaller evaporative air coolers are designed to sit in the window, but larger ones require ducting. The size and location of the ducting will determine how complicated the installation is. Larger units can be installed in a window-mounted location, wall-mounted, or stand fan with water spray roof-mounted location. Some can also be ground-mounted and connected to a forced air duct system.

An evaporative air cooler is also efficient at removing pollutants from the air. A two-stage system is ideal for hot days when moisture is high in the air. A two-stage system will allow the system to evaporate more water while maintaining the same temperature, and this will increase its cooling power. Moreover, the two-stage system does not increase energy consumption. A two-stage evaporative air cooler has two stages, and each stage allows more water to evaporate, thereby providing more cooling power.

An evaporative air cooler should have at least two speed settings. It should also have a vent-only setting, which will disable the water pump and allow the cooler to cool the house without the use of water.


An evaporative air cooler is a great way to save money while cooling your home or business. Evaporative coolers run on water as the working fluid, so they don’t use any toxic refrigerants or CFCs. These units can be easily repaired and can be installed by the average DIY homeowner. Even better, they require only two mechanical parts and don’t require the services of HVAC contractors.

An evaporative air cooler costs between $500 and $3,000 depending on the size and model. Some models come with ice compartments and gel ice packs to make the system more effective. However, these options can add up to another $50 to $150 to the overall price of the cooler. You’ll also need to buy replacement pads for the unit, which may need replacing annually or every few years.

The media for evaporative air coolers must be replaced frequently. While wood wool pads are inexpensive, they’ll need replacement every few months. Higher-efficiency rigid media can last for several years, though this time is dependent on the amount of water in your area. During the winter, you’ll need to winterize your system. An unmaintained or defective system can lead to the development of sick building syndrome and adverse effects on asthmatics.

A home evaporative air cooler can save on energy and is a more environmentally-friendly option for cooling your home. They operate by evaporating water to cool the air. However, you must have a lot of fresh air to use them effectively. The best way to do this is to open windows to let in fresh air. The market for evaporative air coolers is expected to grow by X.X% from 2017 to 2022 and is projected to reach USD XX million by 2029.

The average cost of an evaporative air cooler stand fan with water spray is around $2,000, including labor. This figure also includes the cost of a technician to install the unit. The technician will charge you between $50 and $80 an hour for this work.


An evaporative air cooler is a cost-effective cooling solution for industrial buildings. Its use of low-pressure pumps and fans to circulate water allows it to cool rooms with minimal pressure drop. The cost of running an evaporative air cooler is a fraction of what it costs to run an air conditioning system.

The most common installation method is on the roof, but there are alternatives available. Evaporative air coolers are most commonly installed in commercial buildings, such as restaurants and industrial buildings, where they can reduce temperature levels in a space. Because they use outside air, they need to be properly insulated and protected against freezing. They can be installed in a variety of configurations, including ceiling-mounted barometric dampers or windowsills.

Before installing an evaporative air cooler, it is important to consider the location of the air conditioner’s inlet. It should be placed at least 10 feet away from plumbing vents and at least 3 feet below them. In addition, the cooler should be located in an area where it can easily be serviced. It should also be placed in an area that is free of fuel and chemicals.

Most evaporative air coolers feature a belt-driven system and an adjustable pulley on the motor. This system is similar to bicycle drive systems in that the larger the motor’s sheave, the faster it will spin and deliver air. Ideally, the evaporative cooler should be sized appropriately for its room size.

If you are a homeowner, you can install an evaporative air cooler yourself. This type of unit is a great choice for houses in hot climates. It can be mounted in an attic, a roof, or on the ground. You can even install one in your window if you have an accessible window. The cost of installing an evaporative air cooler depends on several factors.

The average cost of an evaporative air cooler is about $2,000. This includes the cost of the technician’s labor, which typically falls between $50 and 80 an hour. A swamp cooler should be serviced regularly and inspected for signs of failure. Signs of a faulty unit include excessive amounts of corrosion and water leaks. A swamp cooler should also provide consistently cool air.
