Is an Evaporative Cooler the Same as an Air Conditioner?

Many people prioritize keeping their homes cool during the summer seasons. Several cooling devices are in the market today, and most people opt for either an evaporative cooler or an air conditioner. Do they work the same? No.

While both evaporative coolers and air conditioners are capable of cooling indoor air, they do vastly differ in functionality, their region, and pattern of usage. We shall elaborate on the dissimilarities between these two below.

Differences in working principles

Evaporative Cooler

Evaporative Cooler, also known as an evaporative cooler, uses the evaporation of water to cool down. In simple terms, it cools down the air by blowing air over a wet cooling pad, using the property of water evaporation to absorb heat.

• Advantages: Requires less energy because it doesn’t rely on a compressor to run.
• Disadvantages: Has a high humidity requirement and is limited in humid areas.

Air Conditioner

The Air Conditioner, or the A/C, cools by circulating refrigerant. A/Cs draw in hot air from a room and compress it into releasing heat outside, while condensing and other processes and blowing cold air into the room.

• Advantages: Able to accurately control temperature and humidity, suitable for any climate environment.
• Disadvantages: High energy consumption and high cost of use.

Differences in applicable scenarios

Application Scenarios of Evaporative Cooler

The evaporative cooler is very suitable for dry and hot climate regions like deserts or inland cities. In moist air, evaporation is very high. But in dry air, water evaporates faster and its cooling effect becomes more obvious. Additionally, it can increase indoor humidity and make the air more comfortable too.

Application Scenarios of Air Conditioner

Air Conditioner is more versatile and can work properly in both humid coastal areas and dry inland areas. If you need stable temperature control, air conditioning is a better choice.

Comparison of energy consumption and environmental protection performance

Evaporative Cooler energy consumption and environmental protection performance

• Energy consumption: Compared with air conditioners, Evaporative Cooler consumes only 10%-20% of the latter, which is very energy-saving.
• Environmental protection: No refrigerant is used, which has less impact on the environment.

Energy consumption and environmental performance of Air Conditioner

• Energy Consumption: Air conditioners need compressors to work, which consumes a lot of energy, particularly if it has to run for several hours.
• Environmental protection: Traditional air conditioners contain harmful refrigerants that destroy the environment. While new-generation air conditioners use relatively friendlier refrigerants, the overall environmental performance is still not as effective as evaporative coolers.

Comparison of maintenance and cost

Evaporative Cooler

• Maintenance: The maintenance needed usually includes just cleaning of the cooling pad, water change, and cleaning the equipment surface and requires a small cost.
• Purchase cost: The initial investment is lower than that of air conditioners.

Air Conditioner

• Maintenance: Cleaning of filter elements should be periodically conducted, along with checking and changing of the refrigerant as well as compressor, to keep the expenses relatively high in maintenance.
• Purchase cost: The initial investment is high, but it can provide a more precise and comfortable indoor environment.

Selection suggestions

The choice between Evaporative Cooler and Air Conditioner shall be determined with respect to geographical location, budget, and requirement for cooling, as follows.

• If you have a dry climatic area and want some energy-saving along with environmentally friendly cooling method then Evaporative Cooler is right for you.
• If you require an accurate temperature and are staying in a place with high humidity, Air Conditioner is the better choice.

結論

Evaporative Cooler and Air Conditioner are two common household cooling devices. However, there are huge differences between them in terms of working principles, applicable scenarios, and energy consumption. Only by choosing the right device according to your needs and budget can you enjoy the best comfort experience in the hot summer.
