Does Evaporative Cooling Utilize Gas? Understanding What It Is And How It Works
While many cooling systems depend on compressors that need gas, evaporative coolers take a different, more natural approach to keeping your home cool.
Evaporative cooling is a popular and energy-efficient cooling solution for Australian homes, especially in dry and warm climates. After deciding on such an option, homeowners often ask the question: does evaporative cooling use gas? Let that sink in. The short and straightforward answer is: No!
Evaporative cooling doesn’t use gas to operate.
Gas is used as a refrigerant in appliances that have a compressor. But an evaporative cooler doesn’t have a compressor, so it doesn’t work with gas. Evaporative coolers rely on the natural process of water evaporation to cool air, using only electricity—usually less—for the fan and water pump, and no refrigerants.
Now you got cleared with this question. Now look into how evaporative cooling works? To explore more about how exactly this cooling method works, keep reading…
The Basics of Evaporative Cooling
In simple words, this is the process where heat evaporates water – it transforms from liquid to vapor, which helps cool the surrounding air. Since evaporation is a natural way to lower the body temperature, the best everyday example is sweating. Essentially, an evaporative cooling system works on the same idea as how perspiration adjusts the temperature of the body.
When hot, dry air is drawn into the cooling system, it flows across pads soaked in water. The water then evaporates, pulling heat from the air. This process results in cooler air, which is then pushed throughout your home. With the help of a few moving components, the system brings down the air temperature and delivers 100% fresh, cooled air into every room.
Does Evaporative Cooling Use Gas?
No, electricity is needed for Evaporative cooling systems to operate.
It works as follows:-
- Electricity gives power to the fan and water pump, it draws in warm air, goes through the water-saturated pads, and circulates the cooled air throughout the house.
- No gas is used in traditional air conditioners, which rely on refrigerants. When creating a cooling system of evaporation type, which is more environmentally friendly and energy-skilled than traditional air conditioners.
The answer to your question is that evaporative coolers use electricity, and they do not require gas to be honest.
Then How Does Evaporative Cooling Work?
Unlike traditional air conditioners that recycle and cool the air inside your house, the evaporational cooling uses a natural, centuries-old chronic cooling method. It draws warm, dry air from outside and passes it through water-sorting cooling pads. As soon as the air passes through moist cooling pads, moisture in the pad is evaporated, which brings down the air temperature and adds humidity. This cooler, moisture-rich air is then pushed indoors, usually the temperature is reduced by about 10°C to 15°C. However, due to additional humidity, this is not always the best option for an indoor environment.
The two-stage evaporative cooling system improves the air more effectively by cooling the air-dropping the temperature up to 7°C compared to the traditional single-phase systems. This method results in low humidity (about 70% less) and provides better cooling performance.
In ducted evaporative cooling systems, the cooling unit is installed outside the house and contains several cooling pads. These pads are continuously supplied with water from the internal tank. An underlying fan draws hot air in the unit, where it passes over the soaked pad. Now cooled air is distributed equally in your home through a network of ducts.
Modern evaporative coolers go a step further with advanced features. Their pads are often made from fluted cellulose sheets, which resist decay and require minimal upkeep. Plus, upgraded water distribution systems ensure the water spreads evenly over the pad surface, boosting cooling performance and energy efficiency.

- Maintenance needs: Needs regular cleaning of pads, water lines, and fans to maintain performance and air quality.
Beat the Heat with Energy-Efficient Cooling
Why Choose Evaporative Coolers?
The Benefits
The evaporation cooling is a way to defeat heat during the scorching summer of Melbourne, as these coolers are an energy-skilled, environmentally-friendly cooling solution with many benefits for your home.
Soft on Skin, Eyes and Airways
Because they use moisture to cool the air, the intellectual system does not dry your nose, skin or eyes. They are particularly suitable for allergies or asthma victims, who require a breath, soft indoor climate.
Low Energy Bill, High Efficiency
The evaporational cooling is much more energy-skilled than traditional air conditioning. The cost of installation is often half of central air systems, and they consume 75% less energy you get to save money every summer.
Fresh Air, not Recycled
Unlike standard air conditioners, evaporative coolers attract fresh outdoor air, filter dust and allergies, and broadcast it indoors. This means that you are breathing in cleaner, healthy air every day.
Environmentally Friendly Cooling
With the use of refrigerants or harmful chemicals, evaporative coolers are a durable, environment-conscious option that reduces your carbon footprint while you can feel good while resting.
Disadvantages Of Evaporative Cooling
While evaporative cooling is a cost-effective and environmentally friendly solution, there are some disadvantages that should consider homeowners and businesses:
Limited Efficiency In Humid Climate
The evaporational cooling works best in warm and dry climates. In coastal areas of Queensland such as humid areas, its cooling efficiency decreases significantly because the air is already saturated by moisture. It is less effective when the level of humidity is high.
Water Consumption
The evaporative cooler requires a continuous water supply for operation. While this makes them energy-efficient, they can use sufficient amounts of water, especially in large systems. This can lead to high water bills in some areas and can be a concern in water areas.
Regular Maintenance
Regular maintenance is necessary to run an evaporative cooler efficiently. This includes cleaning cooling pads, regularly drought and filter space. Without proper maintenance, the system can deposit dirt, dust and algae, can reduce its effectiveness and lead to potential malfunctions.
Proper Ventilation Requires
To function properly, the cooler must have proper ventilation in the space. In rooms with airtight homes or poor airflows, evaporative cooling may not be as effective, as the cold air may not be properly transmitted, and the indoor environment may be stuffy.
Can Increase Humidity Indoors
While evaporative coolers add moisture to the air, this can lead to increased humidity indoors, which may feel uncomfortable for some individuals. For instance, if you’re in an area with already high humidity, the extra moisture might make the space feel warmer or more uncomfortable.
Noise
Evaporative cooling systems for home, especially ducted models, can be noisier than traditional air conditioners. The fans and water pumps create sound, which might be distracting in quiet environments such as bedrooms or offices.
Not Ideal for All Property Types
Evaporative coolers are best suited for single-story homes or properties with open floor plans. In homes with multiple levels or complex layouts, getting effective cooling can be challenging, as the system relies on even air circulation.
Beauty Ideas
For homeowners who prioritize aesthetics, evaporative coolers cannot always mix with home design. Large exterior units or roof-mounted systems can be noticeable and different from the presence of the house.
