Air coolers work by evaporating water into the air. Because air can only hold a certain amount of moisture, the more moisture in the air to begin with, the less you can add.
The technical answer is to use a psychrometric chart to analyze the problem.
A common thermometer measures dry bulb temperatures (the x-axis on the chart). From that temperature follow a vertical line up until you reach the current relative humidity value. This intersection gives the properties for the air you're trying to cool. From this point, a horizontal line all the way to the left side of the graph will give you the temperature for 100% relative humidity level. This value is the theoretical minimum temperature you can reach through evaporative cooling.
Seeing this with numbers shows that a common value for someplace humid, like Florida today is, 80 deg F and around 80% humidity. If you follow these values on the chart, the minimum temperature you can achieve is around 74 deg F @ 100% humidity.
The same problem with cooling someplace dry, like Arizona, where the temperature is warmer, 100 deg F, but the humidity is lower, 15%, can get a minimum temperature of 44 deg F @ 100% humidity.
This level of humidity is uncomfortable, and most people shoot for around 50%. If you live someplace dry use evaporative cooling (adding moisture to cool a space) and if you live someplace humid, use air conditioning (cooling & removing moisture to condition a space).

Why are water coolers not effective in coastal areas?
Water coolers may not be as effective in coastal areas due to the high humidity levels present in these regions. The moisture in the air can create condensation on the outside of the cooler, compromising its cooling capabilities. Additionally, the constant exposure to saltwater and salt air in coastal areas can lead to corrosion and damage to the cooler.
Why are most of the nuclear plants located near the coast?
Most nuclear plants are located near the coast because they require large amounts of water for cooling purposes. Coastal areas provide easy access to large bodies of water for cooling the reactors. Additionally, coastal locations offer transportation infrastructure for receiving fuel and sending out electricity.
Why are nuclear power plants are located in coastal areas?

Installing evaportaive cooler on my home?
You can install an evaporative cooler. They are only effective in very dry areas. If the humidity regularly gets high, they are not effective in cooling. For more information you can visit the swamp coolers page at www.hvac-for-beginners.com
Why are solar air conditioner are preferred and solar air cooler not preferred?
Solar air conditioners are generally preferred over solar air coolers because they are more effective at cooling and can maintain a constant temperature even in extremely hot weather conditions. Solar air conditioners use a vapor compression refrigeration cycle, similar to traditional air conditioners, but they are powered by solar energy instead of electricity from the grid. On the other hand, solar air coolers, also known as evaporative coolers, use a different cooling mechanism. They work by blowing air over a wet pad or filter, which evaporates the water and cools the air. However, they are less effective in high humidity areas, and they can only cool the air to a certain extent, which is usually a few degrees lower than the ambient temperature. They also require more maintenance, as the wet pad or filter needs to be cleaned regularly to prevent mold and bacteria growth. Overall, solar air conditioners are preferred over solar air coolers because they offer more efficient and consistent cooling performance, especially in hotter and more humid environments. However, solar air coolers can still be a good option for low-humidity environments or for use as a supplementary cooling system.
What are the benefits of choosing a cooling-only mini split system for your home?
A cooling-only mini split system can provide efficient and targeted cooling for specific areas of your home, allowing for customized comfort and potentially lower energy costs compared to central air conditioning.
What are the benefits of using portable air conditioners in small spaces?
Portable air conditioners offer several benefits for small spaces. They are easy to install and move around, making them convenient for use in different rooms. They also provide targeted cooling, allowing you to cool specific areas without wasting energy on cooling the entire space. Additionally, portable air conditioners are cost-effective and energy-efficient, making them a practical choice for cooling small spaces.
How does perspiring contribute to maintaining homeostasis?
Sweating cools down the body through evaporative cooling. As the liquid evaporates energy is absorbed from the skin. Sweating is not effective in high humidity areas.
How does a 2 zone AC system work to provide efficient cooling in different areas of a home or building?
A 2 zone AC system uses two separate thermostats to control cooling in different areas of a home or building. Each zone has its own set temperature, allowing for customized comfort levels. This system is efficient because it only cools the areas that need it, reducing energy waste.
What is the tonnage of goodman CPLE24-1?
The Goodman CPLE24-1 is a 2-ton air conditioning unit. This means it is designed to provide cooling for spaces that typically require around 24,000 BTUs of cooling capacity. It is suitable for medium-sized residential or commercial areas.
Can someone explain evaporative cooling to me?
An evaporative cooling system allows air to be cooled through the simple evaporation of water. This type of element is best used in hot, dry climates such as the western/mountain states and Australia. One things that makes them so popular in these areas is that they can be as much as 80% cheaper than traditional refridgerated air. They are used quite widely commercially in such places as laundromats, dry cleaners, green houses and confinement farming. In areas of high humidity, evaporative cooling systems do not do a whole lot other than just push the air around.
What is district cooling system?
A district cooling system is a centralized cooling method that provides chilled water from a central plant to multiple buildings or facilities through a network of insulated pipes. This system is designed to enhance energy efficiency and reduce overall cooling costs by utilizing a single, large-scale cooling plant instead of individual air conditioning units. District cooling is particularly effective in urban areas, as it optimizes energy use and minimizes greenhouse gas emissions, while also offering a reliable and consistent cooling source.
Why was electricity introduced to urban areas before rural areas?
Electricity was introduced in urban areas before rural areas as there is more population in urban areas. This would mean that there is therefore more demand. Also, in rural areas, it can be harder and less cost effective to provide electricity as it may be just a small cluster of houses.
Various Uses for a Spot Cooler?
A portable air condition, or a spot cooler, is made to use for temporary cooling. Areas where there are not air condition units, or where the units do not adequately cool the spaces for which they are intended, may benefit from this cooling device. Spot coolers are excellent for computer rooms, factories, offices, residential rental homes and temporary business locations.The Inner Workings of a Spot CoolerSpot coolers work in the same manner as window air condition units. Both of these devices are powered by electricity. In order to cool a room, they pull warm air into the condenser and cool the air. Once the air is cooled, it is recirculated throughout the room. The only difference between a window air condition and a spot cooler is that the spot cooler has wheels, which makes it portable. Every spot cooler's performance level is measured by British Thermal Units, or BTUs. Most spot coolers have a BTU measurement that ranges from 11,000-30,000.Dehumidifying and Cooling Computer Server RoomsSpot coolers can dehumidify and cool a room that does not have its own air condition unit or needs extra cooling. Rooms that contain computer equipment, like server rooms, require a constantly maintained cool temperature and low humidity in order for the equipment to stay in working order. Spot coolers are ideal backups for times when the air condition in the room fails.Spot Coolers in Factory and Warehouse SettingsA lot of businesses purchase spot coolers to use during emergencies or during times where temporary cooling is needed. Large factories, such as automotive plants, must perform temporary "shutdowns" at least once per year for maintenance purposes. When central air condition units are not in working order, the factory workers will stay cool and comfortable with strategically placed spot coolers.Cooling Residential HomesSpot coolers work well in residential homes too. People who rent homes without a central air condition unit can use spot coolers instead. The cost of a typical spot cooler is more than the price of a window air condition unit. However, many spot coolers are more energy efficient than their window unit counterparts.
