Are air coolers better than air conditioners?

1. Cost and energy efficiency
Air coolers: They have a lower initial purchase cost and lower operating costs, often saving up to 80% on energy costs compared to air conditioners. They work on the principle of evaporative cooling and require only water and a motor, making them more energy efficient.

Air conditioners: They have a higher initial purchase cost and higher operating costs, especially in high humidity environments, where air conditioners use more energy. Air conditioners use refrigerants and complex mechanical systems, which results in higher energy consumption.

2. Applicable climate
Air coolers: They are suitable for dry climates and are most efficient when humidity is below 20%. In humid environments, air coolers will not cool as well and may even increase indoor humidity.

Air conditioners: They are suitable for all climates, including high humidity and cold areas. Air conditioners perform better in humid environments, effectively dehumidifying and cooling.

3. Cooling effect and comfort
Air coolers: They are not as effective as air conditioners and cannot be set to a specific temperature. They lower the temperature by increasing the humidity in the air, but do not significantly reduce the actual temperature. Air coolers may provide less comfort in high humidity weather.

Air conditioners: Provide faster and more efficient cooling, can precisely control temperature and humidity, and are suitable for environments that require precise control. Air conditioners usually have higher cooling capacity, measured in BTUs (British Thermal Units).

4. Maintenance and environmental friendliness
Air coolers: Relatively simple to maintain, requiring only regular watering and cleaning of the cooling pad. It has a low impact on the environment and does not use harmful refrigerants. However, air coolers can become a source of allergies, especially in humid environments.

Air conditioners: Maintenance is more complicated, requiring regular inspections and professional services. Air conditioners use refrigerants, which have a certain impact on the environment, although modern air conditioners have a lower potential for depleting the ozone layer.

5. Portability and installation
Air coolers: Usually small in size, easy to move and install, and do not need to be fixed in place. Many models are equipped with universal wheels for easy transfer between different rooms.

Air conditioners: Some models (such as portable air conditioners) are easy to store, but split air conditioners require professional installation and the installation process is more complicated.

6. Applicable scenarios
Air coolers: Suitable for users with small spaces, dry climates and limited budgets. It performs well in outdoor activities, offices, shops, etc.

Air conditioner: Suitable for large spaces, environments that require precise temperature control and humidity regulation, such as homes, offices, gyms, etc.

7. Health impact
Air cooler: The air produced is fresher and has moderate humidity, which is good for health. However, air coolers may attract mosquitoes and may become allergens in humid environments.

Air conditioner: Through circulating air and filtering systems, it can provide cleaner air, but it may cause the air to be too dry, affecting respiratory health.

Air coolers and air conditioners each have their own advantages and disadvantages, and which device to choose depends on specific needs and preferences. If you have a limited budget, live in a dry climate, and need to save energy, an air cooler is a good choice. If you need precise temperature control, it is suitable for high humidity environments or large spaces, an air conditioner is more suitable. When choosing, you should also consider maintenance costs, environmental protection, and personal health needs.
